It is here!!  It works !! yeah

It auto seeks an empty ip address just like the sp20.

IT IS TOO LOUD WITH STOCK FAN AND STOCK FREQ OF 350

If you run stock fan at stock freq it is over 75db and is a nasty sounding 75db.

So a sound proof room and ear plugs are needed. My ears rang from the sound after I turned off the miner at stock speeds and using stock fan. (the fan is pictured here)

https://bitcointalk.org/index.php?topic=907219.msg9980310#msg9980310

if your s-5 comes with this fan you will almost certainly want to remove it and find a better fan or two fans.

That said I like other parts of the miner


Well with more test and going to freq 356 I get  1197 gh at 588 watts = .49 watts per gh   this is making the s-5 look a lot better.

I will keep the miner at freq 356 for 4 hours to see if it is stable at 1197gh/588 watts and very few hw's

This may make me think it is better then the sp20 if it continues to scale well as I crank up freq.

1) I got it to do 1156gh at stock speed---freq 350
2) uses 581 watts  at stock speed ------freq 350
3) that is .502 watts per gh
4) auto seeks an ip so if you have a 192.168.x.xxx router it should find an address easy
5) once fan modded sound is okay at freq 350
6) temps are 64 and 58 c  I think this is okay my room temp is 28c
7) gui has huge choice of freq from 100 to 500 in steps of 6.25 or 16 per every 100 total of 64 in all
8 ) new miner interface that allows you to see all your miners  use miner config then miner link

So that is 8 good things.

The bad

1) loud loud loud and since I am 57 higher pitched sound is nastier then lower so the stock fan  running at 3600 or 3800 rpm  hurt my ears.
2) it is an s-1 not an s-3 case.  
3) the black sides are plastic
4) no top or bottom
5) stacking is not easy due to plastic sides
6) my s-5 does not like to do more then 1200gh others have had the s-5 do 1300gh------- this may be the fan mod


Would I buy this at 455 for 1 shipped to my home over a sp20e for 500 shipped to my home
some will say use 2  not 1 miner to price compare
2 s-5's to usa NJ with shipping = 899
2 sp20's to usa NJ with shipping = 1000

well I need to add 54 for new fans so  899 + 54 = 953 s-5 vs 1000 sp20  at this price point the sp20 wins
if I make a big set up 10 or more in my house the sp20 wins due to ease to stack.
some people have setups of long none stacked miners  then it is a tie sp20e vs s-5

If I paid 800 for 2 s-5's shipped to my home and did a fan fix for 54 bucks I would be at 854 usd vs 1000 usd.  for a small setup I would say the s-5 is better in this case.


These are very close to the sp20 if they cost a little less and if you add a fan mod.

These are very close to the sp20 if you are able to manage sound in an isolated area.

These are very close to the sp20 if you want under 5  or if you do not need to stack them.

These would best the sp20 for value if the price drops more say 2 for 800 shipped to the usa vs 2 for 900 as they are now.

More tests later today.

Give us an idea of the noise that the s-5 produce.

yeah a bit of a tease sorry.

I  will have a screen shot of it mining soon note many freq choices

http://imagizer.imageshack.us/v2/1280x1024q90/537/JXdu53.png

it is noisy 67 db with a down clock to freq 300 vs freq 350

noisy WITH a downclock? I can't have two types of noisy miners...was hoping that this one would be tame.
Promise to myself: never order a bitcoin miner UNTIL manufacturer posts a detailed dB table (with various distances vs speed and/or fan speed)

I have a very easy mod will do it and get back

it's the same format as s1, s3, sp20.... the more power it consumes the more ventilation it needs, resulting in higher decibels ;)

anything can be made to run silent, it only depends on your skill and the money available ;D

The multiple choice frequency is an interesting addition ... looking forward as ever to your informed review and information philipma.

first mod is adding the silverstone fan  model  141 from amazon.

the stock fan is the same as always it is  set as a push fan.  It is a weird fan.  38 inches deep yet the blades are only 1 inch.  then a focus set of frozen blades . loud loud loud nasty sound!.

I set the silverstone as a pull and db dropped from 72 to 66 still very loud ,but a huge improvement on power 496 watts and 1077 gh

496/1077 = .4605 watts per gh  so I added the fan and the better cooling added about 100gh of hash.  I smell overclocking possiblites.

now this never happened with the s-1 or s-3 adding the silverstones dropped fan speeds and kept gh the same.  so the gear became quieter not more power efficient .  so the chain design may have a really good benefit if you don't have other issues.
based on this my impression is add a second pull fan asap.  we also need more people to see if this happens to their s-5
forget  all that that it dropped to the same  

http://imagizer.imageshack.us/v2/1280x1024q90/908/Qqx2Dp.png

dB isnt always the best way to do it - a 120mm fan can be loud but at a low frequency and seem much more tame than a 60mm fan at a higher frequency but lower decibles. The S2 used 140mm fans and had a sucking/whooshing noise that was very tolerable in a work environment compared with 120mm fans of similar airflow.

does the S5 have the ability to add a second fan? this could really improve the noise, as could a shroud for the top if airflow escapes that way

okay added a silverstone as a pull fan.

slight clip to make it fit.

the control board takes 2x 4 pin fans

http://imagizer.imageshack.us/v2/1280x1024q90/538/EZxhW6.jpg

two fans.

http://imagizer.imageshack.us/v2/1280x1024q90/540/7yMv0P.jpg

now see this photo.  this is a huge mistake that bitmain did. if that jack was ½ inch taller 2 silverstone fans would make this gear really easy to mod.

I have complain about this more then one thread and others have mention this.  So someone dropped the ball here.
Especially  since this miner has 600 watts of heat to dump not 400.
The sad part is they decided to use 1 fast fan.  This was in my not so humble opinion a fuck up on their part.
I thought I would tame the sound of this miner with no real effort and I would like it better then the sp20e.  I will need to work hard to make the miner quiet.  Just think slap on 2 silverstone fans in 2 minutes and boom a quite or at least a pretty quiet miner with little or no effort.  Right now I unplugged the crazy loud stock fan and I am using the silverstone as pull.  very nice no issues.  but I downclocked to freq 225

I have a new mod in mind for the noise but that will be on tues.

http://imagizer.imageshack.us/v2/1280x1024q90/908/Tuz523.jpg

dislike for the s1 style radiators, gives not so good feelings ;D

curious if those extra ports for 2 more boards are working and if we can upgrade by buying just the boards and use s1 radiators....

just throw a 14cm fan on top of it, at the front!

okay I found a quiet 1200 rpm  120 mm pwm fan for the push  and I have the 140 silverstone for the pull

noise is tamed but I have a heavy under clock.  i need to do so more work but for now I will let it mine

the sides of this are plastic and bend  they will prevent shorts (I think) but forget stacking on the side like you can do with s-3's


this is what I will run over night this uses 361 watts

You got this bad boy in the living room Phil?

ninja edit: congrats on the Legendary buddy!!

in the home theater room or the den.  thank you

when you replace the stock fan with the silverstone you go from a PWN fan to a fan with tach only?  so the silverstone fans go full speed all the time?

what is the CFM of the silverstone?  Volts and amp rating?

I say this because bitmain uses off the shelf chinese brand server fans.  If you use delta or nidec brand fans, you will see a huge boost in cfm with minimal noise increase at stock speeds or better yet, you can slow down those (delta, nidec) fans and have minimal noise and decent cfm.

Thanks for the Review. Spondoolies-tech must be doing cart-wheels right about now  ;D

Biggest failure on the side of BitMain is that these miners are noisy. I guess SP20 wins this round.

I could care less about the noise. How many watts are you drawing at 350 freq and what hash rate?

Too damn right, if you clip a Nidec TA500DC with a resistor (to reduce voltage / amperage) you get a fantastic airflow / CFM with little noise. I think that is because the fins on the TA500DC are a bit longer (and more angled) than on the regular fans that bitmain deploy. I use a several of these on my S1's (don't laugh ... ) in pull position as replacement for the stock fans and they work wonders.

Ouch we are 0 for 2 so far on reviews. :(

no the silverstone is 4 pin pwm it is the pull fan.

I will order this as the push

http://www.amazon.com/gp/product/B00KFCRATC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

these two as push pull should work

Philipma,

Do you know where the cgminer conf file is? I can't find it anywhere - seems to be a different file system to Bitmains usual setup. I want to change the --queue setting, it's set at 8192!!

Cheers.

If you are going to try out another fan, I'd hasten to suggest you look for one with deeper fins. They will provide a higher CFM at lower voltage and be quieter. For example, the stock NMB 4715KL fans that bitmain deploy are 1 inch (2.5 cm) deep, whereas a Nidec TA500DC is 1.5 inches (3.8 cm). If you can get a 2 inch deep fin / blade on the fan, I think you'll get an even better airflow + quieter for if you run them at less voltage.

PS. The Nidec TA500DC is not a 120mm fan, more like a 125mm fan, and on the S1's that I run it on, the holes do not fit those on the frame, however, it fits inside the frame and I attach them using double sided tape, that and the pull layout make it stick rather well. Additionally, I run them without the PWM (though they certainly have PWM as they are 6 wire). You can pick these off flea-bay for a pittance, shipped.

cheap design, not good
S5 sux

So far this review feels like a bit more of how to fix a broken miner with cooling you would do differently, and how to mod it.

I'm confused about the review thread a bit, nothing personal.. just constructive criticism..  Hopefully there is more to come in terms of testing the default clocks and cooling configuration..

I'm not 100% sure the single fan design is "dropping the ball"..   There was a discussion on cooling designs I read someplace here, and a fluid dynamics engineer chimed in and said that a pull only configuration will always be more efficient than a push pull configuration.  He said Fluid Dynamics Don't Lie.

Also.. you mention the Db of the unit, which is a nice thing to give.. but for the laymen.. it would be nice to get an opinion on the volume of the noise by comparison to other miners..  I don't have a Db meter handy, and if I did, I would probably be forced to try to replicate the Db you are giving with my SP20E to get a subjective understanding of how loud the miner is.

Anyway.. so far it seems that you think in your humble opinion that this miner is a dud, the cooling system is dysfunctional, and it doesnt run at stock clocked configuration so you are going to run it at a decreased  frequency because there is a problem with the stock frequency.   Did the miner shut down at the stock clocks?  did it perform over time as they stated it would in the stock configuration?

Did I miss anything?   I'm just playing devils advocate here trying to flush out a fully rounded review of the miner as it comes... plug and play.. and how it performs as intended.  

I know you want to customize this beast to your liking, but how much solid data have you collected in the way bitmain ships this miner?.  Eh, to each his own.. I know you aren't a dummy.  :-)

I ordered an S5 also.. kinda bummed after reading your thread but still excited to get it... We shall see..

Looking forward to your final conclusion of how the miner performed before and after you had a chance to fix it properly... It would be nice to hear more about the miner in its stock configuration though, and how it performs... unless you are convinced its broken by design.


Rich

Oic, from the pic I could only see three wires.  Yea that fan works but at 24 bucks a pop that's super expensive.
I don't know if the board can handle the amps on the fan but you don't need to go full speed, you can get this for cheaper.



Dell  BETA V TA450DC B35502-35 120mm x 38mm Fan Y4574  NIDEC

Or


Delta 12V DC 1.60A Fan Model : AFC1212DE

http://ebay.to/1B0zZ6x

Umm.. not sure where you are getting your ideas from.

Its obvious just by looking at it that the S5  uses a 38mm fan, in fact the NMB 4715KL is a 38mm fan that pushes 130CFM@50dBA, not sure if thats what they are using on the S5 but nevertheless :)

Nidec TA500DC is a 127mm fan the 130CFM version is 48.8dBA and the 150CFM version 52.5dBA so not much in it.

The Silverstone is actually a better fan than both of them
Airflow: 42.8~171 CFM
Noise Level: 13.4~43.5 dBA(Max)

Even at max speed its more powerful than the Nidec and quieter than both, plus it uses the standard 120mm screw holes :)

Not saying its the best fan for the job, just that its not a bad one to try if you have it lying around from other stuff :)

Phillip is like a decent amount of people here that run miners in their homes.

Down clocks for better wattage and to keep the power bill down as well as to try and keep the unit nice and quite for the home. If what he's saying is true and its loud, then it wouldn't be a good choice for home miners. And don't forget its a review, why run it at stock when your supposed to run it threw its paces.

Some people buy a miner based on what it would be doing in 3 months, you can run a miner for a few months stock but whats the power / efficiency like when you need to down clock.

I sure wouldn't want an SP10 under my bed, or in my room (Got a C1 to do that, nice little heater)

Yes phillip is a tinkerer trying to get the best watt/gh ratio with low noise as possible. Its a refreshing approach, not one everyone always considers, but he'll probably be mining long after we give up from electrical costs :)

Are you sure that the network port if blocked if you use the Silverstone 140mm fan?  I've replaced the front fan on my S3+'s with the Silverstone 140mm fan and it goes just to the bottom of the network port and with a unsleeved network cable it fits fine.  If the S5 is the same as the S3 as I suspect, then it should fit even if others have said it doesn't.  If it's just at the edge, shaving a mm off the fan should work also.  With one in the front and rear, it should be able to have the Quiet setting on the fan for both and still have enough airflow (hoping).

Those are not ideas, they are the facts as I have them.
1. The NMB 4715KL has a 38mm frame BUT the fan blades / fins are, like I said, 25mm. I know this because I've just measured one. And it is classified as a 120mm fan.
2. The TA500DC has 50mm frame and the fan blades are 38mm, just like I said. It may indeed be classified as a 127mm fan (against my 125mm), but my point was that the holes on it will not fit a with the frame of an S1, and possibly S5.

I have no claims to make towards comparative noise levels, but like I suggested, I clipped mine with resistors to reduce the voltage / wattage and they work wonderfully with my OC's S1's with little noise, much better than the stock NMB 4715KL (even with the blue wire hack!). I put that down to the size of the fan blades.

And by the way, there is no speculation in my comment, and therefore no chance of confusing / mixing numbers like you did, just un-udulterated observation.

A superior pull configuration only works in the case is fully sealed. The S5 is not sealed, so a pull configuration would be horrible on it.

Controller on the top again :( Heat rises. Guess I'll be running 'em 90 degrees on their side (or upside-down on a wire rack) like the S3's.

Just remember nidec have different models of the ta450dc although frame will not vary.
Worst case even if the holes don't line perfectly you can't beat 10 bucks shipped.

Hello：
      You can modify 'user_setting' file in /config directory to change --queue setting.

Yep they do, and more pertinent different depths.

38mm - 120CFM max 43.1dba @ 2750rpm => http://www.nidecpg.com/fanpdfs/c2003_4546.pdf

51mm - 190CFM max 56.7dba @ 4000rpm => http://www.nidecpg.com/fanpdfs/c2003_4747.pdf

I was referring to the latter type (model A34538-90 but can not find its datasheet though plenty on fleabay!). Also the CFM & noise levels at the reduced voltage should be the ones that matter, as I am sure they will be better than the stock fans, possibly even the silverstone.

There ya go petey, shoulda been more specific, the nidec fans I've used are mainly the standard TA500DC 38mm fans (http://www.nidecpg.com/fanpdfs/c2003_4546.pdf), so I couldn't imagine how you were thinking it had a 38mm fan blade inside a 38mm housing. I didn't know you meant the 51mm WIDEBODY TA500DC monsters that came out of old compaq servers etc.

Interestingly Nidec were also the OEM for the very popular range of watercooling fans in the Scythe GT range.

Anyway no harm no foul, just don't get your fingers caught in those suckers!

I have to live with my miners too..  oh, and believe me.. I'm all about the underclock and the tinker.. 

I think out of the gate its pretty well understood that the design of this miner and the BM1384 is such that it has a narrow overclocking and underclocking potential when operating at 12v (In terms of watts per gh).. if he had his hands on a 9V 10A PSU, I would applaud him doing underclocking tests... and would bit sitting on the edge of my seat to see what he discovered and shared here. mod it up with a silent high flow low rpm fan.. neat!  Thats the mod I want to see...

I'm sure there will be some in depth S5 modding thread(s) coming.. unless this one ends up being it..

Anyway, I'm interested to see where this review ends up in summation and final thoughts..

It is really a ping pong thing to call the 38mm as the standard ones ..... 51mm one may actually be the standard ones, but never mind, though you should have thought of the 51mm ones seeing I'd suggested they had 38mm blades ....

But more interesting from your point of view, is what CFM + noise level would you get from those 51mm fans, bearing in mind that the ones that come from the compaq servers are 12v 2.7A they are bound to have a higher CFM rating than those in the 51mm datasheet, i.e higher than 190CFM (of course even the dba), BUT at a reduced voltage, the dba will be less (possibly less than the stock /silverstone running at medium), and the CFM too (but possible higher than the stock /silverstone running at medium); then there you have a good substitute.

Nice work Phil.  Keep the info coming.

Okay just got back home from a party. I need to find a few other fans.

 at freq 250 I do 824 gh and 404 watts that comes to .49 watts per gh.

 I bounce to 416 watts which is .504  watts per gh this is good.

It will run too hot with my current fan setup if I go above freq 250. temps are 60c and 57 c

It is too  loud stock!  it runs hot at stock speed with stock fan. stock fan ramps to 3800 rpm and temps were over 60c for each board.



 if you want db's 75 plus it is a nasty  pitch.

my complaint is really simple here 2 silverstone 140's would allow it to run max speed and quiet. A no brainer 1 minute mod.  instead I will need to fuck around with it.

If noise does not matter run it stock.  It is louder then the s1 or the s3 it is as loud as the asic miner tube.  So far at 225 ,250, 275, 300  and stock 350 it scales close to .51 or .52 watts

per gh. I am looking at the stock fan and it is a bizarre fan.  It is 38 mm yet has 1 inch deep blades I have never seen a fan like this. I have to go back and correct part of the review.

3 shots of the  my wife will kill me sounding  stock fan.  it has 38mm depth with 25mm blades then 13mm focus grill. it was pushing 3800 rpm at freq 350 worse sound of any fan I ever use for a miner.

http://imagizer.imageshack.us/v2/1280x1024q90/673/3bn6I6.jpg

http://imagizer.imageshack.us/v2/1280x1024q90/537/dIZxMi.jpg

http://imagizer.imageshack.us/v2/1280x1024q90/912/kAtEmz.jpg

That is a crap fan! It looks like the ones that ship with the AMT 1.2 miners (are they 12v 3A?) Do they have a sticker and care to post a photo?
The design of the safety /focus grill is what makes them whine (and therefore loud), but I suppose they were chosen because of the CFM they can output, but if running normally is 3800rpm .... then I wonder.

EDIT: I think this is the fan (220 CFM 12v 3.3A max 64.8 dba) - datasheet => http://www.nidecpg.com/fanpdfs/va450dcf.pdf
the ones that ship with the AMT 1.2 are V34809-INT1F

good news I have a delta 3 pin fan a 38 mm runs at 3000 rpm.  I put it in place of the four pin pwm  fan  and it is pushing at 3000 rpm.  using the silver stone 141 mm to pull while loud it is not holy fucking shit loud.

So it is imperative  to understand the stock fan sent to me is not usable in a home it is too loud and you must get better fans.

I now push  at 3000 rpm since it ia a 3 pin it will just do that.  and the silverstone is pulling at at 1440 rpm temps are 51.

So I think I can now do a  higher freq testing. So I am jumping to freq 300


http://imagizer.imageshack.us/v2/1280x1024q90/633/hEQanT.png

http://imagizer.imageshack.us/v2/1280x1024q90/538/dXWQW1.png

and so far freq 300 with new fan setup is good.

http://imagizer.imageshack.us/v2/1280x1024q90/540/PgmKfW.png

  freq 300 has settled in at 999gh and 489 watts

I have a delta 3000 rpm 3 pin fan as the push it moves 113 cfm  I have the silverstone 141 mm as the pull it is running at 1560 rpm

watts are 488/999 = .489 watt per gh  

Here is my impression you must get new fans.  as to the best fans over the next few days I will test for some.

temps are 57c and 54c in an 80f room.

okay 22 minutes in with a push pull setup at freq 300  we have

975gh
489 watts at kwatt meter    
delta  push fan is 3000 rpm
 silverstone pull fan is  1560 rpm
temps are 57c and 54 c
db is 61 at 1 meter and pitch is okay


going to bump to freq 325

Just to recap, if the stock fan is the V34809 (http://www.nidecpg.com/fanpdfs/va450dcf.pdf), then with a top rpm of 5300 (and assuming a linear increase in CFM and dba), then to get to stock cooling levels you'd need:
(stock rpm / fan max rpm) * fan max CFM = Stock CFM
(3800/5300) * 220 = 157 CFM
Applying the same simplistic logic to the dba: (3800 / 5300) * 64.8 = 46.46 dba
Thus any fan that can provide over 157 CFM with a dba less than 40 would be better.

PS. I know I am most likely wrong, but please don't shoot!

philipma1957 Thank you for the review!

What are your thoughts on 2x SILVERSTONE FHP-141 140mm (1 push, 1 pull)? Not going to be too much for the board to handle?

okay fan has no label   FXDS  IS IN TWO DIFFERENT SPOTS.  

I won't use it as I like my ears.  the two fans I have are a 3 pin 38mm delta that does 113 cfm max as push and the silverstone 141 mm by 38mm does 170cfm max as the pull  I know that 113 + 170 = 283 cfm total but push pull loses some of that.

as i have ramped up to freq 325 watts are now 516 to 530  and a board failed so I will go to a lower freq. many x's and 1 0

 this issue could be my seasonic 760 watt psu not the miner


I dropped down to freq 306  and I am good  no hw's temps are 58 and 54

I may stay at this number for now.  I need to get a better psu out as this 760 watt plat seems to want to stay at the 499 watt level on my kwatt meter.

at cryptoglance  i seem to be running 2 fans safely for now I do not know rating on the fans I use and the board powering them but  so far so good.

Is there a reason you can't increase the temps above 60C?

no I think 65c would be okay but I never ran an s-1 or an s-3 at that temp.  So I do not mind going at a different temp.  I just switched the  silverstone to quiet

and the 3 pin is still at 3000 rpm the silverstone dropped to 840 rpm with temps holding at 58c and 54 c

see freq 306 numbers   watts are at 495-499

Thank you. I expect to have this miner in my hands soon. Hopefully I can mod two silverstone fans for a better noise level.

Cheers

okay I opened my new evga 1300 g2 up since the 760 watt seasonic plat crapped out at freq 325 and liked up to freq 306.

I am back at freq 325 and I will see if there is an issue with this freq.

 at freq 325  watts are 542

 542/1027 =  .53 watts per gh 

 So over freq 306 may be when this miner loses best watts per gh.  db is 59 at a meter  distance the pitch is okay. stock fan  was 75db!! pitch was nasty

 there are better fans then the 113 cfm delta 3 pin  but this delta and this silver stone cost me about 10+ 17 = 27 bucks  .   I think I will run this at 325 for 6 hours then change to higher.  good night folks

Didn't you go from a Platinum to a Gold PSU? You should expect slightly higher power draw with the Gold.

Not necessarily, it depends on the efficiency curve which usually peaks at about 50% of max. load and that would be closer on a 1300w than a 760w.

yeah and that plat has done a year of mining. it dropped out 1 board to all x's and 1 zero  after a few minutes of mining at freq 325.

  the evga is 2 hours old. still solid with the freq 331.

going to bump to freq 337

I had a thought, now please remember this is just a thought and probably not to practical(cost efficient) for the home miner, but what about a waterblock cooler, something similar to the C1. If the heat is dissipated by the top of the chips then this should be an easy application, perhaps not by us, but perhaps bitmain in future releases. By that I mean it wouldn't be worth the cost for a home miner to buy all the required parts to watercool. if they could machine a waterblock that could intake/exhaust the coolant at the top of the block, perhaps intake at the top back and exhaust at the top front or something like that, then one could still stack sideways, cool extremely efficiently, and run a full loop system that could cool perhaps up to 3-5 units per radiator(haven't done the math, just spitballing). In theory I would guess that at stock speeds, this would keep the chips running under temp compared to a fan setup. Also as a bonus I would think a single fan used as a booster cooler to cool the interior of the unit would be an idea. Just remember this is only an idea that popped in my head so please do comment, I'd love to hear what others think of this, Good or bad. I'll prob post this in a few S5 threads to get some extra feedback.

IMHO the main mistake is to use such an semi-open case. It should be just like S3 has, also with two fans to provide more intensive and directed airflow...

these 2 fans are 10 on ebay-delta + 16.95 on amazon -silverstone = 27  

1 s-5 = 480 in the paypal group buy + 27 fans = 507

1 sp20E= 500 group buy.  must buy 2  = 500  

    at that price point  and running both at 1100 the sp20e is 7 dollars less  and at 1100gh uses less power per gh and appears stronger built .  

so a quick  set of opinions is the s-5 needs a price drop.

the sp20e is better made  has  case that is easy to stack.

the sp20e has a better gui

I need to test more but if I was buying  more  pieces and I was to pick the s-5  I think 400usd counting shipping is closer to a competitive price.

 

If I was to run an 100 unit setup I would not pick the s-5 due to case weakness.

The sides are plastic no bottom or top.  These are like an s-1 with plastic sides.  A big setup would be a P.I.T.A  compared to the s-3  or the sp20E .

 stacking these s-5's is not easy  you will need to take some care.




I ran over night at freq 337  power was 563 watts at the kwatt meter  my 2 replacement fans are hanging  there db wise 60 db at  1 meter.  the 3 pin runs at 3000 the silverstone is at 1800 rpm it has a max of 2000 rpm. the noise with this setup is better then the noise a sp20 makes if you drop fans to setting 20 and mine at 1100.

563/1108 = .508 watt per gh.  very few errors

results below>>>>>>>>>> I am bumping to freq 343


http://imagizer.imageshack.us/v2/1280x1024q90/661/GmKYWt.png

Nice best share. 1 year ago this would solve a block.

Nice review @philipma1957 , thanks for your work !

  Just got freq  343 working

it is at 1099gh   and 1 HW error after 20 minutes.   so far  going over and staying over 1100gh is not that easy to do.

  I think I will change the pool setting for diff to d=1000

I will try to go to 1155 and 590 watts  but so far I seem to flatten at 1100 gh and 565 watts.  freq 331 337 and 343  all give near 1100gh with 562 watts

this is with a newly opened   evga 1300 g2 and 4 cables.

bitmain wrote its possible to run s5 at 0.2w/ghs (less hashrate) with a 9v psu. is there a way to test it?

What the size of fan
To replace with better one??

yes but I won't be able to try it for a while.  this psu


http://www.ebay.com/itm/400-Watt-Adj-Volts-9-15-DC-36-Amp-HAM-CB-Power-Supply-Real-USA-MegaWatt-/180777043955?pt=US_Radio_Comm_Device_Power_Supplies&hash=item2a1726c7f3



can provide 360 watts 24/7/365   so with it lowered to 9 or 10 volts and freq lowered to 200 or 225 on an s-5 you should get low numbers.

the problem is this psu is around 80% efficient   so if you use a 92 efficient evga 1300 g2  and 12/12 volts  or a 80 percent efficient megawatt 9/12 volts  

you make out with the 9/12  volts ratio and lose out with the 80/92 efficient  psu ratio


simple math is 9/12 x 100 = 75  then  92 /80 x 75 = 86.25       still better then the 100  but not as good as 75

once you add in the price of the psu vs an atx you have in house it kind of does not pay.

I have talked with a forum member about  a down volt  'pot' device   this would be about 87 % vs the 80%  of the megawatt psu.

he may  Post about this device in a week or so.

@ jelin1984

stock fan is 120mm by 38mm  .   my push delta is 120mm by 38mm  my pull  silverstone is 140mm by 38mm  but has  120 mm fan holes.

my fans kept the temps at 60 and 57 with freq  350  my watts  were at .5 and hash at 1154 hw were good

so I now went to  freq 356  will get back  later.

I am not sure I understand: do you suggest Noctua as a push and Silverstone as pull? Why not two Noctuas (one as push, another as pull)?
Also, would I need to clip a wire on any of them?
In addition, what is that Delta 3pin everybody is talking about? I look at ebay-there are many different variants.
Thanks, much obliged.

Well I know the noctua fits on the push side under the ethernet jack. the silverstone is a combo 120/140 mm fan and only fits on one side.
I had the silverstone in house I know it is a good powerful quiet 4 pin pwm fan.  this is why I use it.

I will  look for a ebay link on the 3 pin delta

http://www.ebay.com/itm/Delta-AFB1212VHE-120mm-x-38mm-Very-High-Speed-Fan-3-Pin-Connector-148-CFM-NEW-/121150995989?pt=US_Computer_Case_Fans&hash=item1c35297e15

Thanks, Phil. I am trying to price in various options. The delta fan is ~$18 with shipping (ebay), noctua (also for push) is $24.5, but the fan looks awesome.
i found another good pull fan (1500 pwm): also Noctua ($18.99) on Amazon
http://www.amazon.com/Bearing-Cooling-NF-P14r-redux-1500-PWM/dp/B00KF7QO2G
I see the advantage there in size-Silverstone is 140/120, so although it has 120mm spaced holes, it will stick out (that's why is covers the ethernet port, i assume)
Two Noctuas together $43.5 with free shipping since it is above $35 (or prime).

I got the second silverstone to fit I used a nail clipper to remove a little bit  of the shroud and it fits  under the ethernet jack. I am boosted to  freq  356 and getting 1202gh using about 595 watts still under .5 watts per gh.  but 2 silverstones cost me 34.52 with tax and shipping from amazon.

 a 35 dollar mod is not cheap. but the meter reads 60-61 db and a lower pitch.  temps are okay and hw's are 0 at 30 minutes.

I think the silverstones won't keep up with freq's much higher then  356 .  those noctua 1500 pwm's do not move enough air for this machine.
the two silverstones are giving me good sound not nasty and temps are still kind of okay my room is 80 f / 28c  board temps temps are 62 c  to 67c

philipma1957, are the Two silverstone fans on the high performance mode or quiet mode?

Yes! Excellent - thank you  :)

Can you also tell me if your cgminer fork is set to submit stales or not? If not, can I add the option in the same config file as where the queue setting is?
P2pool can use stale shares to find good blocks, so is throwing away good shares if cgminer is not submitting them.

Thanks again.

high setting as  quiet is not cool enough . here is how I fit the second fan

I use a nail clipper  to remove a little of the fan shroud

http://imagizer.imageshack.us/v2/1280x1024q90/537/wCDBzL.jpg

then plug in the ethernet cord which seals the hole most air goes into the
heatsink since the cord sealed the shroud cut

Phil, what fan speed on the SP20E matches the noise of an S5?

Phil, do you happen to have an oscilloscope that can do FFT? It'd be interesting to do a spectral decomposition of the noise from the SP20, S5 and Silverstone fans.

For those who want to mod, the delta fan on ebay is $11.51+6.11 shipping, so ~$18
Noctua $24.5, silverstone $16.99 (both at Amazon), but they don't have silverstone in stock (I did not get immediate shipping confirm).
I think that noctua, silverstone and delta all could be used as push (with some clipping of silverstone as phil has done-to fit in the ethernet connection).

However, I wonder what would be the best choice of a pull fan?
This fan provides up to 76.8 CFM (is this enough?):
http://www.amazon.com/Cooler-Master-Blade-120-Radiators/dp/B0030DL37I
If 76.8 CFM is not enough for a pull fan, then what would be? Silverstone is ~170CFM-possible overkill for a pull fan?
thanks

that would be awesome because some anti-noise setup would be theoretically possible.
http://en.wikipedia.org/wiki/Active_noise_control

I'd suggest these inexpensive network cables like this without the boot (connector sleeve) if you're going to use the Silverstone fan up front, better than removing so much from the fan frame.

http://www.amazon.com/gp/product/B00E5I7VJQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

yeah they do not quite fit but you could sand the shrould on the  silverstone  rather then clip it.

At mr teal alas no o-scope.

but the two silverstones run at 60 db in a room that is 55 db due to 7 sp20 fans near by in the garage and in the guest bedroom.

My upper end was freq 356 which did  1202 gh at 585-599watts on the kwatt meter.

So it goes a tiny bit beyond specs.

bitmain specs are :
 freq 350
hash 1155 gh
watts 590

my best specs are
freq 356
hash 1202
watts 585-599 at the kwatt meter

I did this with an evga 1300 g2

when I went to freq 362 I got a row of x's


my next test will be to lower freq to 300 and set  the 2 silverstones to low.

this will be a very quiet setting if it cools the unit off.  

  after 10 minutes I get this

sound is pleasant you could watch tv or run this in an office.  I could sleep with the noise this makes.

watts are 492-497 and hash at 1013
temps look too high will drop it to  freq 293

Hum!!!  Great info for under clocked condition.  Thank you for the status page screenshot.

Picture is good

I'm curious, does anyone have a sidewinder they can test with this unit?

http://www.sidewindercomputers.com/df12gf.html

nice fan, but i think the noise problem is an issue with the PWM settings. allowing th eboards to have a higher temperature setpoint would help a lot.

53C & 3850RPM at stock is a lot of noise, but i think up to 58C would be acceptable
39C & 3000RPM at 225MHz is silly though. the fan should drop to 2500RPM or less and let the temps idle closer to 50C.

Im running off -3C intake and the fan is approx 3000RPM at 7V with 375MHz speeds and <54C   (using PWM drives the fan to 3950rpm and the temps only go down 3-5C)

So at full clock with stock fan this is best set in a garage?  Is it feasible with fan mod at full clock for living room? ::)

yeah the stock fan has  poor temp control.   I dropped the unit down to 250 and still was spinning at over 3600 rpm

If I want to clock low I can have a pretty much silent miner

this gives dead quiet.  now if I had a 10 volt power supply   the 417 watts over 823 gh  would be really good.

http://imagizer.imageshack.us/v2/1280x1024q90/538/KNxrdo.png

it is a little too loud to run at full speed in my living room with the 2x silverstone fan mod.

but I don't have enough fans to play with.

 the right fan combo will let you run this at 300 freq if you are in the room.  maybe a little more.

then in 2 minutes switch to freq 350 if you leave the room.

the built-in PWM settings are pretty high. I think if you use a cooler air intake you could run 90cfm fans and as long as the temps are <60C you should be just fine. Im running the stock fan on 7V w/o PWM (approx 3000RPM) and overclocking with -5C intake air and 54-56C temps

I have a spare bed room I am going to open the window to allow for colder air.  I will then try  higher clocks.

It is running at  freq 362 and doing 1193 gh temps are  66/67  but i am only 5 minutes into the test run

try running the included fan at 5V without PWM. The noise is managable (slightly louder than s3, but about 30% of the 12V volume), and the board temperatures should be about 54C in cold air or 63C in a warm room. Its still not something for a living room, but a basement or spare bedroom would likely contain the majority of noise

well that option is no cost.  even if it is louder then the 2 silverstone fans you save 34 bucks.

I am running mine at freq 343 I get almost 1149gh.

my unit does not seem to do well for over clock.

I have to say at 343 with the 2 silverstones it is a decent miner and quieter then the sp20.

I am running this overnight at 343 should be good.

Firstly, Kudos on a great post Philip!

The form factor, the power cables still enter from the now open top. Ether on the end. With plastic sides, this makes, the form factor is rather different. Almost impossible to stack the s5's?
The SP20 has the edge here, fully enclosed and easily stackable with cables all on one end.

It sounds as though Bitmain and the s5 followed AM's one fan option to dump a lot of heat. We know that didn't work out too well long term.

With the small price difference, lets be honest, I'd prefer something that is a Ferrari, over a plastic sided heater.

An afterthought, cooling is easier also on a large scale with stackable single end entry.

edit your post! i didn't write that!

s5 has two things going for it:
1) it can operate at 0.5w/GH and up to 1300GH+ on 12V, whereas the SP20 is using closer to 0.6W/gh (or about 150W more) to achieve similar speeds
2) it should be cheaper to produce - if so it might be a viable farm option and a better fan control system would allow home use.

you could stack these the same way as with the S1 or s3 - I often made 3x2 stacks with the units on thier sides and the bottoms of the units against each other or a flat surface.

the s-1 was not easy to stack the s-3 was easy.  I have stacked  s-3's 4 high on the sturdy metal sides.  The s-1 you could stack two high but you then needed to make sure they were held by something.
  
 Frankly I still like this s-5.  I would buy more if I did not have 9 sp20's.  At 2 sp20's for 1000 usd vs 2 s-5's for 900 >  I would pick up sp20's.  But that's just me.
 If the s-5 were 2 for 800 shipped They would clearly be a better deal as of now I give the sp20's a small edge.

I can not get my unit to do more then 1200 gh -----------may be due to the fan mods may not.  s-3 batch 1 had low performers  and high performers.

 Two other reviewers got to 1300gh  if my s-5 went to 1300gh and used .5 watts I would rate it better.

If you stack them on their side, do they slide around a bit? I was thinking of using some of these in between them (from the gpu rig days): http://www.amazon.com/gp/product/B00004YOHP/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

4 small pieces of this would work well.  small like ½ by ½ inch or maybe ¾ by ¾ inch

http://www.amazon.com/3M-Scotch-Mounting-5-Inch-75-Inch/dp/B00004Z498/ref=sr_1_1?ie=UTF8&qid=1420034507&sr=8-1&keywords=double+sided+foam+tape


You could do 3 high by 2 wide.   3 sets of  wires all face out on the left for access 3 sets of wire face out on the right for access

Good idea, thanks!

How would this be done?  Direct to +5 on PSU?

  yeah the stuff is low cost staples has it.  go small so you can separate them if you need to.

 I use this tool also cheap I prefer the 'stiff' blade not the flexible blade  http://www.amazon.com/Stanley-28-140-4-Inch-Nylon-Handle/dp/B000NNK8DI/ref=sr_1_5?ie=UTF8&qid=1420042603&sr=8-5&keywords=putty+knife

back to fan tests I got the expensive noctua 3000 rpm  pwm fan

it is now the push fan

noctua push :

http://www.amazon.com/gp/product/B00KFCRATC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

silverstone pull:


http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1


btw the way both noctua and silverstone prices went up on amazon. 

this is now more then 24 + 24 = 48 dollar mod.  there are better fan choices price-wise.

Just put it in and all sound problems are gone. 

previous price silverstone (16.99) is on backorder. Do you rec any other fan , especially for pull?

I found a really good deal on ebay five minutes ago.

http://www.ebay.com/itm/Delta-AFB1212SHE-Computer-Case-Power-Fan-120X120mm-Lot-of-5-/191443200211?pt=US_Computer_Case_Fans&hash=item2c92e768d3

5 fans for 29 + 12 = 41 bucks  they are pwm   meaning 4 pin  speed control direct plug into the s-5   

 2 of these would be nice for an s-5.

 I  just ordered 1 set of 5 fans.

how silent/noisy are these: more or less same as noctua and silverstone? i thought that you used one delta before?

Keep in mind those ones are the 150CFM version, not the 240CFM AFB1212GHE. It is a good price though, especially for one ready to go with long leads and the 0.1" 4 pin connector.

yup, feed 5V to the red wire, GND to the black. Even a 7V adapter (yellow and red wires from PSU) helps a lot to drop noise. ideally you should get it as slow as possible while achieving <62C

I used a 3 pin fixed  speed delta  which was  about 148cfm ran at 2800 to 3000 rpm it was a decent  fan purchased  form the same ebay seller  months ago. it was louder then I liked.  these on ebay will ramp up and down if clocked higher or lower at 8 dollars each two of these would be decent.  they will cool as well or better then the silverstone or the noctua will cool.  they will be not as quiet as the silverstone/noctua

they will be much quieter then the  stock fan.  since I order them from the west coast and I am on the east coast .  I may get them for monday.
I purchased them to help buyers find the best fan compromise ... at  8 bucks each 2 for 16 just clip a tiny piece on the fan connector and they will plug right in.

  I think a lot of people would like this better then the stock fan.  and at 16 bucks an s-5 pretty cheap much cheaper then 2 silverstones or 2 noctua's.

klondike_bar's idea of a fixed speed to the stock fan is a possible work around.   

thanks, much appreciated. in the end, I ordered this set and two noctuas, which have a very fast shipment using prime (will be here on Fri).
silversones were either backordered or shipping mid next week, so I cancelled those.

If anyone's interested in really pushing it, I have a pile of these TFC1212DE (http://www.coolingsurplus.com/index.php?option=com_content&view=article&id=59:tfc1212de-pwm&catid=5:120mm-fans&Itemid=8) 250CFM monsters (or their Nidec equivalents), along with a bunch of the 25mm deep 150CFM FFB1212SH Deltas that I don't need anymore. Not all have the 4pin ends.

Hi i'm new on this. I have a real interest to bring a couple of S5 home but i have a concern about the no íes issue. I have read the thread and see that it's possible to reduce the noise lowering the fan volts or changing the fan but i don't now so much about cooling systems.

 So can i get any recomendation? I plan to put it in my living room and i my home temp is about 20c whole year, Thank you!

Just fixing the quote train so the quotes match the people. Continue.

no wars over the gear please.

be nice to one another. 

The PWM configuration of the S5 is not good for home use, but if you have a molex-3/4pin adapter that can provide 5V or 7V, it becomes managable.
The SP20 is a similar volume when set to similar specs, but has room to run much faster if you are okay with noise, or slower if you want better efficiency.

Its a close call, and I think the deciding factor is price. AT $500 w/ shipping the SP20 groupbuy is a better deal, but the 3/$1900 pack (~$630 each) loses to the S5.

Thanks for your answer! I have read your review of the Sp20 and definitely it's a close call. I can find an adapter, so i an try that.   

In matter of prices the best option it's the sp20 group@500$ each w/free shipping but its no longer available. So my i'll see my chances with S5. It cost about 510$ w/shipping to my country.

I'll Keep looking for mod, i think that 60 dB it's fine for me.

See if you can find this fan in your country

note it is a four pin pwm model.  I mentioned this  sale  a few post back right here:

https://bitcointalk.org/index.php?topic=907219.msg9994638#msg9994638



and the seller is really  selling them quickly here on usa ebay.

 With the noctua + silverstone  cooling is a little better then 2 silverstones.

I now have the gear running at freq 381  hashing at 1251 power is 621 watts or .496 watts a gh   sound is decent.

 I opened a bedroom window to let in some cooler air.

they are pretty good….

 now if the cheaper delta's from here:


http://www.ebay.com/itm/191443200211?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT


do the trick sound and cooling wise. I hope they cool better then the noctua/silverstone's cool.  I hope the sound is decent.


  I would then rate the s-5 tied with the sp20

my ratings now are made with:

 2 s-5's shipped to my home for 900 + 74  to mod fans = 974-----note the fans I picked went up to 74 for two machines.

 hmmm I wonder if amazon reads this ?

2 sp20's shipped to my home for 1000 + 0 no mod = 1000 .  

 this would change if the price of the fan mod was dropped to 32 not  74 .  making 2 cost  932 not 974

  any way you look at this it is very close and your setup in home will matter.

Weve ordered 24 of these, should be here next week.

Phillip, a tremendous thanks for all the insight and noise fixes. Much appreciated.

Im assuming yes, but I take it there would be no issues running (2) of these off a single EVGA 1300G2 PSU?

Were adding this to our S3+ Farm, and we have a bunch of extra 1300s we'd like to put to use.

Next week, 80 T/Hash up and running! :)

Strato

you can but the cables need to placed correctly  .

Hey Phillip,

Could you elaborate a bit?  Obviously we would run 4 x cables to each unit, and the split pairs running I assume to the same side of a single miner?

Just want to make sure we dont burn the server room down. ;)

Strato

The 1300 would get pretty maxed out by any overclocking, but I can do 375MHz on a CS650M, which is a 612W rail. If your PSU doesnt have 8 discinct wires, be careful with how much load goes down a single wire. a 2-headed cable might get hot if it powers a single board (280-300W draw). using a 16awg or better splitter is likely better than using only 1 socket on a blade as it distributes the input amperage better.

Good point indeed.

Would running our server room a few degrees cooler make a big difference?  We keep it at 65 F. I could bump it down to 62 or 61.

Also, wondering if anyone has given thought to putting together a blower / dryer exhaust hose system.

You can get a single industrial blower rated at 4000+ CFM, MacGyver a distro umbilical with 3" Dryer Hoses, which are super cheap, and easilly run 10x outputs off the blower giving each miner 400 CFM airflow. Using 1 large 18" air tube, you could place your blower away from your miners, or even outside if air temps are cold.

Just a thought! 

Strato

I am not sure that it would matter. I put my first S5 in front of a max airflow from Vornado fan (they are quite powerful)-and it did not cause much improvement in fan speed (still ~3.5 thou rpm even at setting 325). In the same conditions, S1 fan typically powered down to 1600-1800 rpm.

this wiring   allows the left board of each miner  pull say 300 watts on 2  single cables = 150 watts a cable----okay

this wiring allows the right board  of each miner to pull say 300 watts on 1 double cable =  I melted my evga 1300 g2 why oh why did I do this?


A suggestion   set each miner at  freq 275  if you wire two to your  evga 1300 g2  feel all six cables after 5 minutes they should all feel the same.

bump to  287   feel all six cables after 5 minute they should all feel the same ----cool to warm

bump to 300 feel all six cables  after 5 miuntes they  "          "         "            '       '       '

do it till 325 or 331.

 maybe you can go up to 356  



 the evga 1300 g2 can do 3 s-3's  at 231 or 462 hash at about 1208 watts at the  kwatt meter.  you are pulling about 200 watts each cable .  i have done that for months at a time.

Can you translate the "S" and "D"
Single connection cable and double connection?

Hi Philip,

Good review so far.. I'm liking it better than I did in the first 24 hours.   I guess I was a little annoyed at everyone calling the miner a dud, before you made that proclaimation.. probably because I ordered one.

One thing is for sure, it sounds like its a noisy beast...

#1  Do you know what the stock CFM/RPM, etc is for the 12038 fan which is included.. and what its model number is, or a link to the specsheet?

I may have found a nice, quiet, pretty high cfm fan for a push/pull, or strictly pull configuration which would be sufficient for home mining. Looks like a great combo of watts, cfm, and noise levels.  How do you think it would fare on the S5 in terms of achieving proper cooling >1TH/s in terms of environmental requirements, room temp, or anything else you can think of.  I'm thinking this may be a nice upgrade for myself or anyone concerned with the sound levels of the miner.

yes so the left board has 1 single and shares 1 double

the right board has 1 single and shares that  same double.

four plugs into 1 miner and 3 cables into the psu

the 1 miner pulls  about 580 watts across 3 cables about 200 a cable

the load is balance correctly since each board shares the double cable.


@RchGrav   that fan is one step below this fan a little less air a little quieter


http://www.ebay.com/itm/191443200211


which sold out in under 6 hours since I posted about it in this thread.

you pick or the one above should work.  the one above is gone.  hell maybe mix one of each.

I had the 3 pin version of yours it ran at 2800 or 3000 it was okay  I did some testing early but it was not a pwm.

It cooled better then the noctua cools.  it was noiser then the noctua

it cooled worse then the stock fan.  it was quieter then the stock fan.

So if you get the pwm version cheap why not? the worse case is you will need to run the s-5 at 331 or 325 not 350.

Thanks for this review. I will put this into effect when selecting my next gen miners. I don't think noise concerns me too much since I run them outdoors but hey the less noise the better.

you are welcome and of course if the noise has no meaning  to you it is a good miner.

 with ten miners in my home and a pretty happy wife  I have to keep noise at least okay.

It took 2 years to show her I make a few bucks doing this with a possible upside of more to come.  So letting it sound half way okay is worth it to me.

Heh, lol. Whipped...  :D

Wish I was whipped... :-\

Can you get the numbers on the existing fan by any chance?

Or .. what CFM do you think is actually required by the miner to run at stock frequency under normal environmental conditions?

  Thank you! I'll take a look. Maybe i can find something similar Here. 

  I had a 3000 rpm fixed speed  3 pin delta delta it was between 2800 and 3000 rpm . quieter then the stock and kept the gear cool enough to go to freq 350.  I think it is 148 cfm at 3000 rpm

Any idea on the model number of that fan?  Trying to go by CFM and dBA on spec sheets I'm scouring... and when I start spec hunting I tend to go overboard.

and well... I went a little crazy...

I ordered a ridiculous SAN ACE 120 fan model 9SX1212P1K001.. (available from Mouser, Newark, Element14, Farnell, Arrow and Sager)

Here is a video of an older model Aluminum Sanyo Denki 6000 RPM fan...  

https://www.youtube.com/watch?v=XTdD5FXlrsk (https://www.youtube.com/watch?v=XTdD5FXlrsk)

The operation range of this fan is 15% PWM which is 2600RPM/88.2CFM @ 37dB to 100% PWM which is 7400RPM/257.7CFM @ 66dB

For those looking at aftermarket fans, the Silverstone isn't the only 140mm fan with 120mm fan holes (although it's the only one 38mm thick and probably the best), there are a few others.  Those will move more air at a lower RPM causing less noise.  One thing you may need with some aftermarket fans though that I've learned is that the screws sticking out of the front and back can cause interference with the blades, so something like these can help.  http://www.amazon.com/gp/product/B00NODDHLY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Here are a few of the fans I've found.

http://www.amazon.com/gp/product/B00Q8RLCBU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1  shipped from China so they haven't arrived yet.

http://www.amazon.com/gp/product/B0078IWS6Q/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1  white LED and good airflow but not as quiet as others.

http://www.amazon.com/gp/product/B00B1WQ4VA/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 if you happen to need a shorter fan, not high airflow but pretty quiet.  Optional Static Booster:http://www.amazon.com/gp/product/B00HRJ550W/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1  which makes it as thick as a typical one so this option isn't really useful.

http://www.amazon.com/gp/product/B00G8GUE74/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1  Similar to the Prolimatech above but spins a little faster.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835856013&cm_re=140mm_fan_120mm-_-35-856-013-_-Product  Quiet but not a lot of airflow.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835856015&cm_re=140mm_fan_120mm-_-35-856-015-_-Product  Same as above.

Some of these are right up to the bottom of the network port on AntMiners, so you should use network cables without boots / connector sleeves like these:  http://www.amazon.com/gp/product/B00E5I7VJQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1  
Or you may have to shave a bit off the fan frame.

 

yeah it will be a guessing game to get the correct   fan/price/sound/cfm   frankly bitmain had them before us and could have done some more sound tests.  the stock fan has no marks.  it moves a ton of air (150 cfm or more)    but runs at 3600 to 3800 rpm.  it is fine in a garage not attached. or I guess use a speed controller on it.

 push noctua is 2700 rpm pull silverstone is 1900 rpm -  not quite cool as I would like. considering I am letting outside air at -5c into the room via the window,  but 381 freq is giving 1250 gh at 621 watts plus powering the 2 fans. Sound is really good. cost is too high 24 + 16 = 40 and it went up  to 24+20 = 44

HW's are decent.  Would I run this setup 24/7/365  yeah if I was running 1 or 2 s-5's   but if I had 20 or 30 no.  I think I am just a bit too hot see below.

http://imagizer.imageshack.us/v2/1024x768q90/633/xqFRNo.png

One point-stock fan does not move that much air comparing with SP20 at a low 30 setting. The choice of the fan clearly was not right, since the S5 fan even at 325 (hashing at 1070gh) is MUCH louder than the SP20 fan is at setting 30 (hashing at 1360Gh).
Very much looking forward to see how Noctua-Noctua (expensive at ~$48) or Noctua-Delta ($32) fan combos will work.

 I am going to lock this thread and lock my sp20 review thread maybe on monday.

I am going to sell this to a forum member that lives a few miles from me along with a sp20.

I am done testing it and will give it to him with the stock fan on the side.

  I will install my delta 3 pin and run that .  it is louder then the noctua - silverstone in use, but it cools better.

I have the 4 pin deltas coming to my house  on monday.

  I will give him a pair and ask him to test them.

I would buy these if I needed miners. (I have 8 sp20's)

I may buy 2 of these in a bit if the price drops.

My home is suited to run 7 to 9 sp20's and 1-3 s-5's.

  If you are an established miner that has used s-1's or s-3's and you want to upgrade I suggest  
2 s-5's and 2 sp20's.  I think that would be 900 for a pair of s-5's shipped to the usa and 1020 for a pair of sp20's shipped to the usa.  

  To bitmaintech thank you for the miner  and it was a pretty good miner,  but better fans would have been smarter for you to do.

532 watts 1073 gh  = .496 per gh

clock at 325
push noctua 2640 rpm  pull silverstone  1800 rpm.--quiet

hw's good

http://imagizer.imageshack.us/v2/1280x1024q90/911/zTmL68.png

honestly, just try powering the stock fan at 5V. molex adapters are cheap and you likely have a few lying around if you bought fans in the past. at 5V the fan is about the same volume as the SP20 at 10-20%, and is sufficient to keep the machine cool at stock speeds (as long as its under ~65C, 55-60C is ideal)

not sure how to power stock fans at 5V if I have just regular PSUs.
Edit: saw the picture, care to give a product link-search for molex has >12 pages of products. Thanks.

http://www.directron.com/zmmc1.html?gsear=1

Directron is my fav. stop since it's right by our office.  All my little adapters for fans and such for miners came from there lol.

great, thanks.

You can also look for ones like these (usually come with Noctua fans, warning they can get warm to hot), they're sold out at this link.  http://www.dx.com/p/3-pin-pc-cooling-fan-speed-noise-reduction-cable-5-piece-set-35818#.VKW5W2fwuUk

yeah that looks good and may be best  solution.

good option. searching tech sites and amazon for things like 3pin molex / 5v fan molex / 4pin 5v fan, etc is a good way. Look for one with multiple 5V and/or 7V connections - ignore 12V since that's worse than the PWM. The above link has 2x5v and 2x12V - no 7V options unless you rewire it a little

In your opinion, will 5V support enough speed of the stock fan if intake is ~26C (78F) at least at 325, maybe 350 mhz setting?

All 7V adapters are expensive on amazon and since 7V is 30% louder than 5V, I am not sure that it will change the sound enough (I will experiment with 2 fans setup anyway, since they are coming already).
I know that you posted/tried 5V at 5C intake, which was OK. There is a cold spell right now, so I can theoretically open windows and close the door in the "mining" room, but I am looking at something more stable.

Be aware that some 12V fans won't start with 5V, so you want to test that with your particular fan first.

Thanks, good point, but 5V should work on stock fans, since OP already did it.

With the stock fan, 5V seems sufficient to get it spinning at a good speed, and creates significant airflow. I would suggest making a cover for the unit if too much air seems to escape upwards, as I feel like it improves air movement through the back half of the heatsink. (I used about 4 strips of clear packing tape)

at 26C intake and 5V i doubt youll achieve 350MHz. 325MHz is likely the limit. At 5C I can achieve 381.25MHz+, but at 15C running closer to 360MHz creates the same temperature readings.

I acknowledge this is an extremely stupid question, but its so stupid, I'm wondering if I'm just missing something or have just been drinking too much watching New Years college football.

A PSU like the EVGA 1300W SuperNova G2 has 8 - 8 pin ports (listed as VGA & CPU) and 6 - 6 pin ports (listed as SATA & RERP).  I understand the S5 needs 4 - 6 pin connectors as does the SP20.

So how does the math work here?  For the SP20, you just use the 4 SATA ports and you've maxed out the power.  But with you've got enough power for 2x S5s but only 6 - 6 pin connectors?
   

This question comes up quite frequently. The answer is that EVGA G2 has eight PCI-E connectors, not six as sometimes being posted. The reason is that there are 4 single and two branched connectors (4+2X2=8). Also, you are not using SATA, but VGA ports on the PSU.

http://images.craigslist.org/00606_jBOhOMWRRQg_600x450.jpg

Got it, so somehow the 8 pin goes down to a 6 pin.  So I imagine something like this would only be good for 7 ports then?  Unless is it reasonable to try to replace the melted plastic?

If there is some sort of guide to this that I missed, please let me know so I'm not clogging this up with already asked questions.  Thanks!

that unit above can not do what I wrote below.. you need to repair it.  btw it was most likely melted by using the 2 head pcie cable incorrectly. thus pulling too much power from that plug.

on the s-5 if you plug the two heads on the double cable into one board.  a board pulls 300 watts.  and you melt the plug.



okay I am a bit buzzed but here goes

the s-5 has a pair of pcie jacks. on the left board

it has a pair of pcie jacks on the right board

at freq  350 the unit pulls 600 watts.

each board pulls 300 watts

(shame shame shame on you for bringing up anything but pcie cables> buzzed humor at its worst)

so take 1 pcie cable  color red plug it into a red pcie jack on the evga plug it into the left board. (use a single red pcie cable)

so take 1 pcie cable color red plug it into a red pcie jack on the evga plug it into the right board (use a single plug pcie cable)

now take  a double  plug pcie cable.  plug the single end into the psu. then plug the double plug into the left and right boards of the s-5

so three cables plug into the psu pcie jacks and  feed into the s-5.  if you do it the way I say the s-5's power is divided to the  three cables equally.  since 1 s-5 pulls 600 watts each cable is doing 200 watts.

run the 1 s-5 at stock 350 freq feel the cables a few times all should be okay since the cable are load balanced correctly.

then do the other 3 cable the same wat to the s-5.  the evga 1300 g2 will be doing about 1215 watts at a kwatt meter.  and each cable will pull about 200 watts.

I am a bit buzzed so test this very carefully . and check it every hour or so  for the first 6 hours at least.

Alright, so it (probably) can be fixed.  Any recommendations on where to buy the repair parts?

It looks like those use the non-conventional 8pin PCIe graphics keying. Unfortunately, those are a huge PITA to find. It might be pretty tough.
However, you could snip the end off the bad cable, and wire it with a standard 8 pin Minifit Jr, and then plug it into the CPU spot.

It has a 10 year warranty

Not sure that I understand how this works.
For example, would this work (say, with CX750M that has only split connectors):

D D

I think that it should, I always used doubles on S3 like this. Or has it to be

D---D


D---D
  ^
 fan

Or criss-cross? Or does it matter?  I thought that a single rail system will balance the power draw at each 8 pin connector at the PSU (actually this is where he melted it). That is, I thought that 200W power would be drawn into each 8pin connector if you have 3 cables connected (at the PSU level) to a single 600W miner. Incidentally, since CX750M has only two cords, each would definitely draw ~300W at each 8pin connector while powering S5 at the default speeds.
Maybe I was wrong thinking about PSU balancing power, but would like to hear the physics behind the setups.

What is the potential for damage by running these in an hot environment? Where I work, our server room is pretty damn hot. Right now I run my miners outside my home. Its summer in Australia and its pretty brutal. My miners see 35 - 40c days and hot nights.

Should I be concerned running something like an S5 in this environment?

i think you will need to run at freq 275 to freq 325.

in your case it does not matter   and it will be very hard to run at  freq 350 since your cables should not use 300 watts 24/7/365

the reason it does not matter is you are using 2 doubles from one single rail psu. do matter what you do on one s-5 the cables will be asked to pull 300 watts
_______________________________________________________________________________ ____________________________________________________

this works  

It's unfortunately not that simple; there's no guarantee you'll get a 200/200/100+100 split on the three cables. It won't really matter in the end as you know for sure that you aren't pulling more than ~25A per board even with a bit of an overclock, so you have a lot of headroom there.

In the case of the CX750M, I'd probably recommend going with a single double ended cable to each board.

I haven't seen any problems overclocking mine to 400M in a 40C room.

as long as temperatures dont read much higher than 60C youll be fine i think. fan might get pretty loud though

That's crazy ! You must have some legendary S5 that was forged in Mordor... or something...

EDIT: Board temps <60C ?

Yes, the stock fan is quite loud, but it maxes out long before the ASICs register 60C, so unless I do a fan mod the high temp is not the cause of the noise. The heatsinks themselves are barely 50C, so I'm not worried about it at all.

I clocked to 412 with temps at 58 and 56
I sold this miner to a local  miner from this forum.
 his setup will allow the loud stock fan and the delta 3 pin  which runs between 2800-3200rpm.

 I did my last test run this morning pretty good numbers if you don't mind the nasty sounding  77db fans.  this got about 1300gh at 676 watts that is close to .52 watts per gh  and maybe 10 watts is from that second delta fan.
 the stock fan 4 pin  (3900rpm) is the push
 the delta 3 pin (3100rpm) is the pull

http://imagizer.imageshack.us/v2/1280x1024q90/910/bFy0W6.png

I'll be ordering two of these when my last miner is gone. Noise doesn't concern me, the Bitmine unit I have here is noisy as all hell and is unbearably hot to run.

if noise is not an issue they are pretty good.  I sold mine and he has an added pull fan.  it clocks to 412 and temps are about 58c.

if anyone want this miner and also want  away from the noise at the same time
you can go for me

i provide host service for s5 and charge host fee according 0.1$ per kw'h
which means if the power consumption of s5 is about 600w, the host fee for one s5 is 0.6*0.1*24*30=43.2$ per month

i am not scamer, i have provided host service on this forum for more than 6 month, even philipma host one a1 miner in my data center for three month

I did business with pcfli  and he was okay.   

He may be good for you if your power is too costly.

I am not sure how he is setting up hosting of this gear.

 lee put up  a link to your thread  if you want to.

To anyone  that uses pcfli I get no money from lee.  And while the deal i did with him was okay I do not know the future .  His place is in China.

 I do not know any details and I do not know if it will work out for you.  Lee  sold me and hosted a dragon miner for me for 120days and then purchased it back. His service was good not perfect. Say April 2014 to August 2014.

  I  broke even on this more because of good btc price sales on my part.
For the 120 days of hosting I was up and hashing around 118 days. Which was more then 98% up time.

Who cares for the noise :P
what is the hash rate?

Thanks philipma for the clarify of my service
those s5 gear will hosted on our big farm in chengdu with good stability, which have run for two month without any downtime
i will get my thread ready for the s5 tomorrow, but if you want to check my record, you can go
https://bitcointalk.org/index.php?topic=514758.0

we will test the real power consumption of s5 when it arrive and charge host fee according to 0.1$ per kw.h
should be around 43.2$ each s5 per month.

I maxed at 1290-1305 at freq 412 with a second fan for cooling it used 675 watts.

I'm surprised that the discussion about replacement fans are more focused on their airflow volume (CFM) rather than static pressure (mm/H2O) which is more significant in heat sink/radiator applications.  High static pressure fans are more capable of penetrating through dense heat sink fins such as in the AntMiner devices.  I think there's a reason why Bitmain engineers equip their units with very powerful industrial 12038s with high static pressure (directly proportional to loudness) instead of just mainstream consumer-oriented 12025s.

For better cooling results without a shroud configure your fans inwards as push - push  not push - pull

I did tried on s1 and is crap! the hot air was getting stuck in the middle and temps rose like ~5c!
putting the unit on the side may help ::)

true in the case of  one  push fan only.  but two high cfm fans as push pull get around that.

 since neither one needs full penetration of the heat sink using high static pressure,   but if you don't care about sound the stock fan with a good pull fan cools best.

Push-pull configuration is only effective in an enclosed unit (S3) and not in an open-chassis design (S5) though.

 

    I ran the s-5 with the stock fan pushing  and at freq 412 the temps crept up to 67 and 65 .

   I ran the same freq with the 148 cfm 3 pin delta as a pull and temps never went above 58 and 56 at freq 412.  so for overclocking adding a high cfm pull fan got better results.  

I am sure  that a sealed box would have helped more.

While that should absolutely be true, I can say in my experience the front heatsinks went from too hot to touch to cool to the touch with a high cfm pull fan installed on my S5's.

In your scenario (adding a pull fan in an open S5 unit), the pull fan is able to help dissipate some hot air coming out at the other end of the heat sinks to a certain extent (hence the temperature difference), courtesy of the powerful high-static-pressure (loud) stock fan that is able to force air through the dense heat sink fins.  The key is to have a high-static-pressure fan that is more efficient in pushing/forcing air through restrictive heat sink/radiator fins for optimum cooling, enclosed case or not.  I did add pull fans to my S1s back in the day because it helped to a certain extent.

AND  to be clear the stock fan pushing at about 3900 rpm  and the delta fan pull at about 3000 rpm is silly nut job loud.

I read 75-77db at 1 .1 meters.

But it allowed for an easy freq of 412  and hash of 1290-1300 with power of .52 watt per gh

Unfortunately though, optimum cooling efficiency usually comes with a price (loudness).  Also consider that a good part of that "loudness" is due to resonance created by turbulent air rushing through the restrictive/dense heat sink fins; and this is actually good.  It means that the fan is doing its job.

yeah it is true.  but this miner is pretty good if you have a place that hides the sound.  My freq 412 worked really well for a few hours before I backed it down to freq 375 and sold it off.

I can't take advantage of this miner due to the loud sound.  It is too loud in my garage. which is directly under my bedroom.  But lots of miners have spots where the sound does not matter.  And this miner will work well for them.

I don't think that it is loud with noctua fans-you tested it first anyway. I compared directly with SP20 and noctua fan makes S5 less loud than Sp20 at fan setting 30 (underclocked to 1.35 th). The expense is the problem with this for a larger deployment. I am waiting for delta to do a noctua-delta combo (~$32) and will also check noctua-noctua and delta-delta ($16) as well. If any of these would work, I can deploy more. I cannot deploy more SP20 (have two) because even at setting 30 they are still a bit loud for home.

yeah my sp20's work because I can do this in my attached garage a six stack with fans at 20 speeds at 1200gh this six pack will run until may.

I have 2 more on the far left in the last photo.

I will probably need to sell them off in late march or early april

 if it gets hot just open the garage door:

lastly sound control:

As always love the garage (ghetto) setup, just like mine.  You must have at least 3 different circuits in your garage though don't you?
I have a gable vent at the top of mine which I place a box fan blowing out and added some larger vents for intake, works great.
For sound control, other than fan mods, I considered building a sound baffle case out
of MDF and an itntake and exhaust fan, but maybe it's best open air while it's cold around 40f without anything running.
Waiting on taxes to purchase to try out. Can't wait another 3 weeks, eek. 

No years ago I wired my home. 

I lived in New Jersey  the home was built in 1970 during the Vietnam War the USA had a copper shortage and a few states allowed for Aluminum wiring.

BAD BAD BAD many house fires.  So  NJ came up with the law that if it is your home and you live in it you can diy your house wire.  Just pull a permit from your town and have the town inspect it.

So I went from 100 amp to 200 amp 20 circuits to 40 circuits.  I did everything but the actual box.  Saved a ton of money and ran lots of circuits to the garage.
My garage has 5x 20 amp circuits  for 120 volts wired with 10 awg wire. 

I can do  9000 watts  of power in the garage  safely.   It is too hot  for that even in the winter.

  So I run 8 sp20's at 1200gh/600 watts = 4800 watts.
  If I were alone in the house I would have purchased the 15 unit farm and run 15 of these all around the house.

what is your power price per khw in NJ?

edit:
off topic

according to http://www.eia.gov/state/rankings/?sid=NJ#series/31
it around 15-16 ct

which means, even with best efficiency on market, you never make some money with it, assuming you had to spend nearly 4500 bucks (plus PSUs) for your units, and difficulty also as BTC/$ stays roughly the same, which it won't.
250 bucks/month profit is maximum if you don't reuse the heat energy.  ???

okay, currently you got nothing if you leave you money on bank account (USD).  :P

Hello there,

I'm from Russia and have ordered 1 x ANTMINER S5 BATCH 4.
Now I need some advice from you ...
I have a new out of the box PSU Fractal Design NEWTON R3 80PLUS® Platinum
http://www.fractal-design.com/home/product/power-supplies/newton/newton-r3-600w
and I'll going in anyway to connect it to S5.
Which are the potential minuses I'll get if use the PSU NEWTON R3 with Antminer S5? Please list all if it possible.
Thanks.

it will very likely work fine if you underclock the S5 a bit not to exceed the 600w 12v single rail.

Prompt novice how to do it? Let me know instruction or links.
Thx.

plug the pcie cable into in one side not two sides.

plug the ethernet cable into the s-5 and into your router or your ethernet switch.


it should turn on and start to mine in a minute or two.

look for it's address with an ip scanner

angry ip is free

advanced ip scanner is free   both for windows.

mac has a free one on the app store   ipscanner

once you find the ip sign on to the machine

the sign on is http://192.168.x.xxx          the x.xxx you find on the ip scan   my s-5 was http://192.168.0.191

once you are on the s-5's  GUI 

set freq to 300  down from 350   this should be low enough to run both sides of the s-5 with that psu.

Don't really think the FD PSU will have any issues running at 600W. It should be ok even at 650W

What do you guys think about Scythe DFS123812H-3000 Ultra Kaze 120mm x 38mm Case Fan (http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=DFS123812H-3000&rh=i%3Aaps%2Ck%3ADFS123812H-3000)?

I am planning to order 2 of them for S5. That Delta by RchGrav is OK maybe, but for me here in Russia that Scythe Ultra Kaze 120 mm is quite cheaper.....

My S5 is mining away at a little over 1.1THs on default settings at my pool https://www.kano.is/ working fine :)

I am working on an undervolting solution.

some info here

https://bitcointalk.org/index.php?topic=872014.msg10069844#msg10069844


the hope is it will be ready for testing in 3 weeks.

 I would get a unit to review and run an s-5 from the builder.  The builder is a forum member and well respected.

it would allow you to plug in an atx psu like the evga 1300 g2 and dial it down from 12 volts to a 11 to 7 volt range.  with only a 5% loss of efficency.

 if it works maybe 800gh at 240 watts for an s-5   maybe 800 gh at 300 watts for an s-5.

 right now the s-5 does 800 gh at 400 watts. 

Sounds interesting Phil. So far I am happy with my S5 but know the time will come to do some undervolting.

For those who have a mixed miner set (S5 and SP20): I replaced the stock fan on S5 with Noctua 120mm 3000 PWM, which is quieter and OK for freq 325 at up to 30C ambient (maybe OK for freq 350 if your ambient is colder), but interestingly, Noctua is a little whiny alone, however when I put both S5 with Noctua and SP20 (at setting 20) together, the most annoying frequencies of both seem to cancel each other out and the whole setup (two Sp20 and two S5) "sounds" better. So, maybe Noctua-S5 produce an 'anti-noise" to SP20 noise or vice versa.
http://en.wikipedia.org/wiki/Active_noise_control

Look like there are two unused connector in controller. I wonder is you can use them for another board in case fail controller.

I only had 1 machine but I am almost certain that is possible.  I wonder if a 2x s-5 owner has tried to do that.

Will be interesting if it's work  :)

From what I heard from Bitmain, it's as simple as supplying 9V instead of 12V on the PCIe connectors.
9V PSUs are a different issue all together.
... and the 12V to 9V step downs I found were not all that cheap either since you'd need 4 of them.

I suspect this may be appropriate (times 4):
http://www.amazon.com/VvW-Waterproof-Converter-Die-cast-aluminum/dp/B00J6ODYKY

But I'm no hardware guy so someone else would have to make suggestions about what and how.

At 600W draw at the wall, that'll only give you around 10% headroom.  If you're comfy with that (also keeping in mind that it's a Platinum PSU), then that's your call.  I'd monitor it very closely for the first few days.  Also, make sure that the PCIe cables don't get too hot especially during the hottest ambient temperature that you could possibly have.

I'd get a 750W/800W PSU if it were me though and overclock to heart's content without worrying about power requirement.

Phil I just seen where Bitmain crossed out the 9V feature on the S% sells thread? I guess this is no longer something for us to look at in the future?



Notes
1.   Power consumption figures vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
2.   PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 4 PCI-e connectors for +12V DC input and all four are required. Do not connect more than one PSU to the same hashing board.
3.   When better power efficiency is needed in the future due to higher network difficulties, you may want to buy some special PSUs 9V DC with more than 10A output, which will allow you to have a 0.2J/GH mining efficiency, but at lower hashing speed.

Apparently when Bitmain revised the initial posting for the S5 for 9V feature, they also struck another part regarding the 1 fan cooling solution, though they didn't fix the entire posting. One part still extolls the virtue of a single fan that keeps the miner "cool and quiet". I think everybody agree the 1 fan keeps it cool, though by most accounts it's quite loud in doing so.

Anybody know if there is a revision to the fans on the S5?

not so according to dogie's thread.  dogie said since 9 volt psu's are rare and you kind of need to know what you are doing. they crossed it off.

I must remind everyone I have yet to see any demo on this 9v setup so I AM IN THE THE DARK SO FAR. This is a hoped for solution .

Agreed.

I've found the relative differences between certifications to often be pretty much immaterial, often a case of a few percentage points that could be re-claimed elsewhere for less.

Considering the base efficiency of these devices, I would aim for higher capacity over slightly better PSU efficiency at this time, as you said. Also, based on what I know of average electricity rates in Russia, I expect he would benefit from OC as you suggested.

what I have found is the units scale well using a good 12 volt psu.

Ie they use about .5 or .51 watts per gh at freq

250
 275
300
325
350 stock
375
400
412 my highest test.

So if you can keep it cold and do freq 400 it does the same watt per gh as freq 250  .

 i tested between freq 250 to freq 412 with a platinum seasonic  760 watt psu. 

My best was .495 my worst was .512 per gh. this make the miner good if you can manage your sound issues.

I got mine in totally different packing, some see true hard plastic, but not the usual white box, strange...

Usual white Box???

They went away from the sytrofoam packaging to inflatable air filled packaging. I like the new stuff a lot better, actually.

I think he means the white foam. And yes mine came also in hard bubblewrap.

Nice to know you're still around :D

Indeed, the difference between a Bronze and a Gold PSU (85% and 90% efficiency respectively) is really not that significant in terms of operational (electricity) cost savings over price difference justification.

For example: with a stock S3+ running at 30C ambient, the difference between an 85% and a 90% efficiency PSU of the same wattage rating (identical load %) would be around 21WAC at the wall which equates to 0.5kWh per day.  At a rate of $0.12/kWh, that's a difference of $0.06 per day in power cost savings when using a 90% PSU over an 85% PSU.  For the purpose of extrapolation, let's use $40 as an average full retail price difference between these PSUs.  That would then give us $40 / $0.06 = 667 days = 22 months = 1.8 years to recoup such a price difference.

Of course one could argue that Gold/Platinum PSUs can be had on sale + rebates.  That's true for the Bronze PSUs as well or any PSU for that matter.

The difference between a power supply for running a single S3 isn't going to be $40. You're looking at more like $15 or so.

You can buy a 650W gold supply for only $75. The only other PSU Newegg carries that would work without cable splitters or leaving a PCIe connector unplugged that's cheaper is a $60 550W Bronze one or some refurb Corsair 750's.

You might have $40 difference if you're looking at 850W or 1000W supplies, but you're probably looking at more than a 21W difference there.
I'd say that mining is far and away the best case for making up the cost difference between Gold and Bronze. It's probably closer to a year payoff the difference in cost just on electricity, but at the end of that year you're left with a likely better supply that has a higher resale value.

Fair enough and in that case, I could also contend that since the BFL days, I was able to purchase Corsair CX500s 80 Plus Bronze PSUs at the Egg at a final cost of as low as $9.99 ($39.99 listed sale price minus $20 rebate minus $10 instant promo code discount) and in turn, used those rebate cards to acquire more CX500s at virtually zero out-of-pocket cost.  They have powered BFL, Cube, S1 and currently, S3 miners without missing a beat.  My point is that we really can't mix in discounts, rebates, refurbished units, resale price, etc. and expect to have a controlled comparison (hence the last sentence of my last post).  I think the most sensible way to approach such comparison in order to have a modicum of control with such a variety of complicating factors is to compare the list price of a brand-new Bronze and a brand-new Gold PSU (not refurbs and excluding complex factors such as discounts, rebates, resale value, etc.) with identical/similar wattage rating within a brand as prices vary extensively across brands of identical/similar units.

Since this is an S5 thread, let's narrow it down to the 750W PSUs.  The following is a link to a comparison chart at the Egg with a sampling of five 750W Bronze and Gold PSUs ranging from the cheapest Bronze (Logisys @ $64.99) to the mid-higher end Gold (Seasonic @ $129.99).  Note that there are more Gold PSUs between $129.99 and $199.90 which makes the average price difference to be way more than just $40 across different brands.  But let's focus on the "within a brand" comparison which is between the Corsair CX750 Bronze @ $84.99 and the Corsair RM750 Gold @ $119.99 -- a difference of $35.  That's  almost $40:

Egg comparison chart of five 750W Bronze/Gold PSUs (http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=100007657%20600038000%20600014094%20600037998&IsNodeId=1&page=2&bop=And&CompareItemList=58|17-170-029^17-170-029-09%23%2C17-153-174^17-153-174-TS%2C17-139-040^17-139-040-TS%2C17-139-055^17-139-055-TS%2C17-151-087^17-151-087-TS&percm=17-139-055%3A%24%24%24%24%24%24%24%3B17-151-087%3A%24%24%24%24%24%24%24)

In the end, it's how one justifies it.  I think it's more like a choice of either enjoying the savings now or enjoying it later when the price difference will have been recouped over a year or two later.

Thanks for the discussion on Power Supplies, and the Newegg link. My only comment is that it might be worth considering a larger more capable supply, in anticipation a future mining device. It seems that many folks purchased a "way over the top" PSU in the past, and just continue to use it when they upgrade to a newer mining device. It looks now like the PSU is the "long term" part of mining, while the specific ASIC gadget has a much shorter "life span" in terms of how long it stay connected to your purchased PSU.

Thanks again.

It's been like that for a lot of time!
Even in pc's i kept a case and psu for 5 years but the rest of hardware was changed monthly ;D

I have a small collection of Corsair CX500s that I got for dirt cheap collectively as I've mentioned on my last post on the prior page that have continuously been powering a variety of miners since the BFL days and none of them have failed yet.  I still have a few spare left and I intend to use them to power S5 miners (one for each hashing board) if and when I do get them.  Even if an extremely OC'd S5 draws 700WAC at the wall, that would still give each CX500 a very comfy headroom of about 35%.  Since I already have them, there's no point in investing in pricey overkill PSUs considering the low BTC price coupled with overpriced miners.  I think the ultimate goal is still and has always been to achieve ROI as soon as possible.

Would you mind selling one?

You're better off watching for rebates at the Egg for the CX500.  They offer them pretty regularly and if you time your purchase at a reduced sale price with a rebate and possibly an instant promo code offer, you hit the jackpot. ;D  The key is to keep monitoring the product listing and watch for these deals.  Instant promo codes usually appear/disappear overnight and in some instances, they last for a day or two (I think).  I suggest to avoid the modular (CX500M) version which usually cost more anyway.  The single modular PCIe harness that cascades into 2 PCIe connectors gets hotter than I'm comfy with.

Currently at the Egg, a CX500 is priced at $64.99 ($44.99 after $20 rebate offer which expires on 1/9/15):

Nice review!

Thanks for share!

Will wait and hope someone with a free review miner uses it as a test in case it does not work as planned.

I'd nuke the Logisys from the list. That's why I excluded some PSUs from my search; I don't want to deal with cable issues. The Logisys only has two PCIe cables, and trying to pull 20A+ through each connector on a PSU designed to pinch pennies is a recipe for disaster. On the S1 it was easy because you could just chop the end off a 4 or 8 pin EPS cable, but it's not so easy anymore.
Also, I'm not sure why you included the cheap Logisys but excluded Rosewill, but the Rosewill Capstone 750W (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182073) is extremely well rated (http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=266). It's only $80 for the non-modular version, which is cheaper than all the ones you had listed except the Thermal take, which was only $5 cheaper. :)

Just trying to stay within brands is a little silly though. For instance, Antec has 7 PSUs between 750W and 900W, and the Gold is the cheapest.

I would definitely agree with that you can pick up cheap units if you're only looking at a couple, though that pertains to better rated ones as well. Really, I don't disagree with most of what you're saying, I just disagree that it will cost as much as you suggested to move to Gold from Bronze, or that it would take ~2 years to recoup the difference in most cases. Given an average cost to move up to gold at ~$20, if you're pulling 600W at an efficiency difference of just ~3% (most Bronze exceed spec by more than most Gold), you're looking at 18W which is a 385 day payback on power. Worth it IMO to get other benefits you often see in a better PSU like modular cables and especially moving away from group regulated designs like many Bronze PSUs are.

Like I said, it's ultimately a matter of how one justifies it.  We can debate to eternity and still would not be able to come up with a definitive conclusion that we could both agree on as there are a variety of factors that are difficult if not impossible to accurately and consistently quantify.  In other words, it is a very relative and subjective topic.  At least, I attempted to have some sort of controlled comparison by isolating complicating factors to the best of my ability/knowledge and providing numbers/computation.  That's all we can do in this matter.  If you're happy with the justification of your PSU choice and I'm happy with mine, that should be good enough.

I like the evga 1300 g2's for 10 year warranty.
They work well.

 really like that they can run 2 s-5's or 2 sp20's if I down clock.

I like that they make less wires and space. then 2 or 3 smaller psu's

lastly they come with a trick switch for the psu to turn on.

My evga's have

1 run my s-1's
2 run my s-3's
3 now run my sp20's

Since I have 4 of them I have spare wires and such for them.

visdude has also offered a few ideas on the go cheap as you can route they can work for some and not for others

as my evga 1300 g2 pick can work for some not others.

I'm not at all disagreeing with your method, just that your numbers don't match with my experience in terms of the average price difference. It's not a matter of justifying my choices at all, I don't actually use ATX PSUs at all for mining, other than for some testing. I don't need the minor rails so I generally just buy server PSUs. It's hard to beat the value of a 2450W Platinum PSU for $50. :P

That's why there's a thing called "cable management".  To some, it's a worthwhile challenge that's rewarding when done successfully. ;D

Convenience (non-essential features) is not a function of effectiveness (performance).

Edit:  None of my cheap PSUs has conked out yet.

I think you are drifting towards debating semantics.  Let's leave it at "relative and subjective" while we're ahead and not digress. ;D

Just in case you missed it, I did qualify my original post with "For example:".  I did not intend or claim it to be a definitive presentation.  I'm not sure why you're nitpicking it.  It was merely to show one of many possibilities and I had to come up with a price difference of $40 which is sound, valid and reasonable to base my computation on.  You contended that it is less than $40 which is another possibility and that's fine; so is a figure above $40 as I have illustrated.  Again, "relative and subjective".

I wish the wife would let me run a 220 line for a pair of them. oh well

Is there an interface board available for the 2450W PSU?  I have a Delta DPS-2000BB with a Gekko Science breakout board, but I like the idea of a Platinum PSU.  If there isn't a interface board available, would you mind sharing how you wired yours?

Do more people use the server power supplies or the standard ATX power supplies int heir home use?
It seems to me I hear about the PC ATX more, and I got a heck of a deal from a poster on another forum. The EVGA 1300G2 and Corsair AX1200 are running my pair of 'doolie SP20s. I bought those two, an EVGA 1000 G2 and a EVGA750 shipped for 350. They were used, but they were also spotless, so the guy cleaned them well or they were not used much except in a very clean environment.

I bought a crapload of 36" 16 gauge cables from klondike_bar, and used some C14 cables I had laying around for power. I actually included the proper connectors so I could remove the line and 12V cables along with a toggle switch to turn it on and off, but you don't have to. Minimum cost I could have been up and running for about an extra $20 for 8 PCIe plugs, which would be just about right for an SP20. You might want 12 cables to run 3 S5s per PSU though.

Hey all! About the fan, I found 2 or 3 fan that should do the trick with push pull installation!

 ;D I bought 2 of each of the 2 first. Will let you know when I receive the miner!

they will work with an underclock .  not with stock speeds or an overclock.

Because of the cfm ??

I have two S5 coming this week  my question is i can use two of these on each S5 I hate noise I'm 58 .  I have two of these fans right now on  one of my S1 I'm  replacing with S5 .I'll either junk the S1's save the heat sinks for some thing later on or sell them super cheap on Ebay.


http://www.amazon.com/gp/product/B00FKNAG7Y/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I have them in a isolated basement ;D

 yeah most of the ones that work at freq 350 are cfm of 140 or more

@topek those 4 pin delta's should work in a push pull 

cool ty i just bought one of these to i gonna test it, i read some place if you use  this one with just one 3 pin plug it can be controlled by a fan controller while the other, same one with 3-4 plug can't be unless you  mod it all most same price gonna see.


http://www.amazon.com/gp/product/B00CIB9BTU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1


there we go

Connector : 4 pin male molex and 3 pin female.There is a 4-pin molex power connector and a 3-pin TAC connector. The 4-pin molex power connects to a power supply and the 3-pin connects to a 3-pin header. You won't be able to use a fan controller to control the speed of this fan. If you want to be able to use this fan with a fan controller, please purchase the same fan with only the 3-pin TAC connector


That is this fan for 4  bucks less im just testing things so i know what way to go for me .

cool  ty  noise drives me up a wall  but that's my age . :) .  btw these are very nice fans to from time to time i watch for deals on them and i keep one or two on hand if I need it .


http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1


some one else on the forums told me once to try them.

yeah I will be 58 this month  and the higher pitch on the stock s-5 is very hard on my ears.  I can't imagine a room of 20 or more of them clocked to freq 375.

I love the fact that Bitmain always comes through with product and is always working on a new product just as they are releasing one. 
I have always believed in home mining and am addicted to it's nature.
But truth be told hardware in the last year hasn't seemed to make the significant leap to pull ahead of the difficulty.
Yes, we can all buy the latest and sell in 2 to 3 months and buy the new hardware.
This just seems to benefit the manufacturers since they always have the hobbyist willing to buy.
I wish from a hobby only standpoint I could keep miners running, but I usually don't have the overhead
for electric costs vs just buying btc outright.

Short story Long, just wish Bitmain could step ahead of the minimal gains in new hardware only to
be  obsolete next month.  I know this is the way it just is, but can't help think they're r&d has the funds to really
help the home miner and the decentrilization.

I have two deltas similar to the ones you have on an S5 that runs very quite. There is a link to a video here it has 15 seconds of SP20s and 15 seconds of the S5. Not a very scientific approach but a quick and dirty comparison: https://bitcointalk.org/index.php?topic=902305.1240 (https://bitcointalk.org/index.php?topic=902305.1240). I like both unit types as they both serve me well.

what is your power cost?

It's low compared to everywhere else at $.09 kwh but running 7 - 8 S3+'s with btc being low made it tough to keep going.
S1's faired better at the start of last year.  Just trying to keep the btc mined without trading it in to pay expenses.  I don't mind paying
additional $250 or $300 in pud costs but why when you mine less than that in btc.

get some S5 sell off the S3  it will be i was talking to some one from Canada he ( hes a home miner ) told me he has to upgrade to S5 from S3 the power is not worth it any more with S 3 and 8 S5 should give you 901.13 $ A month  before deductions and Next Difficulty [estimated] @ 835.69 $ at stock speeds if did the math right . at 9 cents per KW it wont go that much higher .but i wish the Miner would last a little longer may be 7 to  9 month over 3  go try  alt coins its worse im glad there is a company out there like bit main. most the lite coin miner are way worse and very little of  them beyond KNC i have nothing good to say about them . and A2. I know one or two who mine and pay there power cost each month with the sell of bitcoins they told me it  works out for them that way no real money out of there packets they said they are still able to keep a nice amount of BTC on hand even after paying there power cost each month

TY Man I was little worried about the noise i would have to buy some kind of cabinet to put them in or sound proof a cover some how .

Hi,

Whats happening if you use only 2 pcie power connectors?

You're cables and PCI-e connector will melt! Max 250 watt per cable, less if you use flatcables. With the S3 yes, with the S5 NO!!!

So I think I found a solution to the high pitch whine of the stock fans. We all know the guide vanes are what's causing the pitch. I received a fan with a broken blade on my my batch 1 S5's and Bitmain was kind enough to ship me a new one. I decided to do a little experiment today to see if reducing the number of vanes would change the pitch, which for my ears (healthy 35 year old) now sounds more like a S3.

You notice on the vane there is a thicker part on the outer edge, I took some wire cutters and cut every other vane right where the thin part of the vane meets the thicker part (careful to line up the fan blades so you don't accidentally cut one). I then used my thumb and as close to center as possible I just pushed down on the cut vane and it popped right off. Note that the power wires run down one vane so you probably will want to start there and you'll still end up with an odd number of cuts. Here's a picture and for those brave enough to try it, let us know your results. My temps are exactly the same and I do use a high cfm pull fans as well. Still experimenting with those, so far the Silverstone Tek 140mm x 38mm Fan seems to be giving me the lowest temps but these S5's seem to run in all different temperature ranges so it's all subjective.

https://farm8.staticflickr.com/7515/16089177837_65df09d9d5.jpg

that looks like it could work.

As a completely different question coins are now 223 usd.

 next diff may drop back under 39.

It looks more and more like s-5's or sp20s are a home miners only chance .

I get an s-5 tommorrow I will post shots of it with modded delta fans. this will bring me up to 8 sp20's and 1 s-5

I may buy another s-5 but with this drop in coins it is very tough to do.

That has been my thought/plan if and when (a big if and when) I get S5s except I would be leaving only 3 or 4 vanes and Dremel the rest of them out "clean".  If that will not be satisfactory, there's always the Delta fan option.  I'm glad to know that it did make a difference.

My only suggestion would be to remove and test. The vanes do make a big difference in channeling the air down the center and across the heat sinks. I have higher CFM and higher pressure fans that should in theory cool the S5 down better but without those vanes to center the air they aren't as efficient and my temps get dangerously high. Unfortunately we're stuck with the stock fans or Delta's, for us home miners that don't have climate control.

 My miner comes today. 

will post a delta- delta    push- pull    using an external psu for the fan speeds.

No, we are not (see highlighted). I use Noctua 3000-great for 325mhz/1070Gh and much much less noise or Noctua/Scythe combo-OK for 1100 Gh at one step up from 325 (331 something?).

 man i love these S 5 just got my fist one today with  two more on the way . the fans are not that bad  but yea I can see were 6 or more going at once would  drive me up a wall i just sold all but two Zeus miners the noise levels form them are as bad as 4 of these to one of those,it forced me to sell, they use way to much power and i get nothing in return . at least with these i can lower the noise  to were 7 or  so in one room won't be bad and use way less power and get more maybe not a real  good RoI  but some thing worth the effect to me . so all in all  the S 5 are really really nice  for me so far expect the sound over time will get to me so I'll fix it or am as we speak and gonna get 7 to 8 , in time.

okay I finally got an s-5 after selling the demo to a friend.



I am using 2 delta fans push pull db = 61

Stock db = 75

I have a seperate psu that can go from 3 volts to 15 volts   I am sending 9.22 volts to the 2 delta's.


and here are the current readings on the s-5.

nice overclock at freq 393 runs cool .

 I can crank the fans up to 10 volts but at 9.22 volts they do the job and the noise is okay. loud but not crazy nasty loud.

44 hw's out of more then 1,000,000 are nothing.


http://imagizer.imageshack.us/v2/1280x1024q90/910/5T3Kzr.png

Great.
Probably the best hash with OK noise.

yeah got lots of photo's here is the first one

I give my blood for Bitcointalk.   I cut the fuck out of my thumb putting in the deltas.  the fans have really solid blades be careful!!!
http://imagizer.imageshack.us/v2/1280x1024q90/538/VtJ0y0.jpg

next photo I got some screws from lowes

you can get the short ones

http://imagizer.imageshack.us/v2/1280x1024q90/909/qodAWb.jpg
and not use the long ones


http://imagizer.imageshack.us/v2/1280x1024q90/538/6BzD9O.jpg


if you do this use two short and two stock screws per fan.  put on grills my thumb still hurts!!!

stock long screw holds the grill
http://imagizer.imageshack.us/v2/1280x1024q90/538/ebgAot.jpg


meter reads around 60 to 62 and you get pretty fast hashing at freq 393

http://imagizer.imageshack.us/v2/1280x1024q90/633/qBQniS.jpg

now to power the antminer.  I used an evga 1300 g2----on the top left   also note room temps is 73f


but I wanted a decent test bed for the deltas
 so here is the power supply and the power distribution

this is a jetstream power supply makes for an amazing fan controller

power distribution and the volts to the fan
http://imagizer.imageshack.us/v2/1280x1024q90/673/VhHkul.jpg

now you do not need that adjustable psu to do fan control


this can do about 6-8 deltas

http://www.amazon.com/Meanwell-Switching-Power-Constant-Ledwholesalers/dp/B007K4XZPG/ref=sr_1_2?ie=UTF8&qid=1421285286&sr=8-2&keywords=meanwell+12v

use 2 of these one pos one neg

and a piece of wood for mounting


will control fans pretty good  may be just a bit too fast.

last test will be how to have the miner quiet with the delta's

I will clock to freq 300 vs freq 393

I would think hash will drop to about 1000gh vs 1290-1300gh--------------------------getting 950gh


I will set fans to 8 volts hoping for 50db and temps under 60c------------------------------58db temps are 54 c in a 73 f room


I went to 7 volts  temps are solid 56/54  in a 73f room sound dropped to 56db  hashing at 978 gh  not quiet enough to run in a room and watch a tv show.    but close.

Will drop to 5 volts as many atx psu's will allow for a  5 volt power supply.

at 5 volts  db is under 48 47.7 db noise is not an issue.  but at freq 300 it is just over 60c in a 73f room.

Have to say if you have a cooler room then 73 f  two of these deltas in a push pull work . you get a quiet miner quieter then the sp20 at 1000gh.

I will post a screen shot  later . my guess is 2 deltas at 6 volts or 2 deltas at 5.5 volts would be better then 2 at 5 volts unless your room is cold.

Phillip how many watts are you pulling at 1300 gh/s?

 670 watts

670/1300 = .515 watts per gh

one thing I like about the s-5 is the power is between .49 - .52 watts.
I tested from freq 200  to freq 412 .

I also think that if you tossed 13

volts at this and used 2 killer fans to kool the gear you could do freq 450 .

In this sense the s-5 is better then the sp20.

My problems are the s-5 does not fit as well as the sp20 in my garage setup. I will run my s-5 at freq 300 .  I will use 2 delta fans and 5.5 volts per fan.
If the s-5 had the s-3 case I would have grabbed 5 to 10 or them.

I am going to try to run the deltas with 4 pins tomorrow . Hook them direct to the s-5 . See if I get the pwm to work.

But you already said, "My temps are exactly the same" (after cutting off some of the vanes).  You now seem to say that (cutting off the vanes) affects the temp.  Did it affect your temp or not?  Which one is it? ???

I am not knocking the cutting up of the stock fan but if it does not work well you no longer have the stock fan.

I got the deltas on ebay for 41 bucks a total of 5 of them that is 8 bucks each .  2 per s-5 a 16 dollar mod.

But I had proper power supply to act as a controller.
Any psu that has  the  adjusting range of 5 to 10 volts  would be a great controller for the delta's.

or this one this centers at 7.5 volts

http://www.trcelectronics.com/View/Mean-Well/SE-100-7.5.shtml

this one centers at 9 volts

http://www.trcelectronics.com/View/Mean-Well/SE-100-9.shtml

both of the ones above could control 8 fans .  get the 7.5 if you want quiet and underclock
get the 9 volt one if you want to run a little louder and overclock.

they are lowe cost cheaper then a fan controller and they run more fans.

or you could use the one I had which costs a little more ,but has full range for the fan speed


the delta's allow me to do freq 393 and 1292 -1300 gh hash   using 9.2 volts in a push pull sound level = 60-62db
the delta's allow me to do freq 300 and 990-1000 gh hash      using 5.5 volts in a push pull sound level = 47.7 to 49 db    pretty quiet


in my setup I am opting for the lower freq as sound is an issue

I will see how well it does in the morning


http://imagizer.imageshack.us/v2/1280x1024q90/538/4oyx6n.png

The number of vanes I removed did not change the centering of the air flow affect the vanes create and my temps did not change. Cutting them out to only leave 4 I think would change that centering effect a possibly temps, I'm just saying if you're going to remove more than every other one, you might want to do it carefully and test between each cut.

Ok I finally install everything.
With my setup, I cant run at 350. I run at 275 and get around 875 gh
But the sound is almost 0.

The temps are 63 and 54 is that ok ?

Im also looking to put 2 S1 fan on it but the wire is to short I need to find extender.  :P

S1 fan is better than no fan, but S5 fan is a lot more powerful than S1, so you may struggle to keep S5 cold enough...

Totally Understand that! Just want to fine a good way to mine at a good temp with a resonable sound level.
2 S1 fan in push pull should be good ? What is the CFM of the S1 fan ?

two s-1's   in push pull will work at least to freq 325.  I tested them.  the cfm of them is around 129-135 and they penetrate air in and out of the heatsinks  pretty well.

Hands down the best is a pair of the delta's from the ebay link.

You can run  quiet (db 47.7)  at freq 300 hash rate 990  or run up to freq 393 at 1290-1300 dp of 60-62   

 the stock fan at freq 393 does db of 75 +   and struggles to cool the s-5.

If super clock is you goal a stock fan and 1 delta gave me freq 412   decent  hash rate 1315-1325   crazy loud db 78-80

The miner is in my living room so I will like to have the best ratio sound vs hashrate.
Im currently 0 dba (almost) but only 275 mhz.
I wanted to test the S1 fan since it was not to high when I run my 3 S1.
I need to find 4 pin extender  :P

I knew a guy that worked for Intel. They would actually have the latest processor chips sitting on shelves, never to used yet because they wanted to milk more out of their current technology. So when you see Intel processors saturate the market that usually means some new chips are coming out on the market. The public has no clue about this, and just like bitcoin manufacturer's, they with-hold information from us on purpose for financial gain. Why do you think all the manufacturers were pushing the hell out of their inventory, having big sales and trying to sell as much as they could right before bitcoin dropped below the $400's. Usually when you have and use inside information for financial gain it is illegal, but since this bitcoin market is unrelated, apparently anything goes.

I know + the gov some times gets stuff that due to be released a year before it's released or 6 month to a year before hand . I remember one time a friend that worked for the GOV showed me some thing that wasn't even on the drawing board so we were being told but it was the GoV had it . that's was a few years back i thought that was a lot of BS till he showed it to me. i think it was a  CD Rom player they wasn't  suppose to be on the market or in DEV,  the GOV had it . if they had it im sure they have stuff we wouldn't believe.

What link is that?

It was a few pages back .  Some one was selling 5 deltas for 41 bucks.

truly these are really good if you use  2 in a push pull at  5.5-6 volts they are really quiet and allow for  a 990gh quiet miner. freq 300

if you use 7 volts  they are pretty quiet and allow for freq 325-350

at 9.2 volts they are better then the stock fan and allow overclock.

I did not bother setting them as pwm as I want a freq super quiet miner .  I send 5.5 volts to the fans   and I am doing this.:

If anyone in Canada is interested and doesn't want to pay shipping and import charges, I have a bunch of 25mm (WFB1212H - 87CFM 37dBA - no PWM, FFC1212DE - 140CFM 54dBA - PWM) and 38mm (TFC1212DE - 252CFM 66dBA PWM) fans laying around I probably won't use again. I have about a dozen each of the 25mm ones, and I think about 20 of the 38mm Deltas (or their Nidec equivalent) though some of the 38mm ones don't have 0.1" headers on yet.

yeah these s-5's with a pair of your delta's the ffc1212de   the 140 cfm  

 I think are nice gear.
I bolded your quote  as It may be a typo.

WHAT? I CAN'T HEAR YOU.

TYPO?

What is the hash rate, and is noise really so loud?

No. Noise is quiet.

Stock S5 is 74 db, its a lot! You need to change the fan to drop the sound.

Delta seems to be the best one!  ;)

stock settings = 1150gh at freq 350 and sound is 72-74db.  plus it is nasty pitch with the stock fan.

"nasty pitch", it's closer to a cat being tortured. Worst than those high speed 40mm fans in network switches. I sold my first two (and only) within 24 hours of receiving them. Modding them simply isn't worth the cost.

the 2 deltas cost 8 bucks each.  but I had a power supply to give them perfect volts

Holy cow, one fan makes that much noise. I was a little interested in picking one of these up, but a constant noise that high is a problem. Technology will take care of the electrical problem (how much they hog up), but what's going to take care of cooling these things silently. Whoever makes something like that will have a winner!

the solution or solutions were posted on multiple threads, if you want to spend money on one or two extra fans (anywhere between $20 to $40). I went with Noctua 3000(push)/Scythe ultra kaze (pull)-good for at least 1100GH at ~58-59C and ONLY ~46dB;powering Scythe through molex directly off the PSU-piece of cake because it comes with an adapter; Noctua connector fits into the same slot as the stock (you have to clip one rail off the connector because it gets in the way). Phil likes two deltas because he found a good deal (two for $20 now, but you have to use an external additional power supply with voltage regulation or it will be louder than I like PLUS these have an unconventional connector).

I am going to show a different way to power it. using a four pin molex I should be able to do 7 volts and directly connect to the psu on the  4 pin molex connection.

this should allow for freq 350 and sound at 56db 

 compared to stock fan freq  350 and sound over 70db

  i  will post a few photos  later today

I just bought this with 2 delta.

Will see the result soon!  ;)

it says it can do 30 watts the deltas use around 15 watts at top speed.  So as long as you run the fans a bit slower it should handle 2  deltas.

Oh my bad. Didnt even take a look at the watt  :o

Thanks philipma1957

Just use 2 fans and back off a bit on the power should run 24/7/365

If you try doing 4 fans it will melt.

Good thank you philipma  ;D

I was wondering will it be possible to modifie one file to modify the fans setup.

I mean, the fan go full power at 50. Could we change it to 60??

That will gave us less noise for better result.

You can try that :

(I didn't test it)

To use it see my post here it is the same manipulation for the S5 :

New mod photos.  First off I use a evga 1300 g2 I plugged in a molex connector to the psu.  I made an adapter that provides a constant 7 volts.  I then spliced the adapter to the pair of delta fans.  very good sound results and very good hash results.     about 52db and about 1100gh at freq 331.

Did you guys saw this fan ??

Koolance 120mm x 38mm High Speed 4000 RPM / 184 CFM Fan (FAN-12038HBK-184)

Its a beast!  :P

I did a separate thread for my fan mod
https://bitcointalk.org/index.php?topic=927941.0

Mr Teal inspired me to use the  atx psu's with a 4 pin molex cable.  I used the evga 1300 g2  ATX-psu which comes with

1)a trick stating plug.
2) a molex 4 pin cable
3) a floppy disk adapter

the psu is on sale at new egg for  169
a rebate for 30 drops it to 139

Canada does that at times.

Hey guys, i ordered some S5 miners and i got them finally.

I have the fallowing question.
Since i have a lot of PSU's left from my alt GPU mining rigs i will be using them. But since i had a good offer back in the day, all my PSU's are Corsair 1200w Platinum.

Yesterday i tested and at clock 375, one S5 is drawing about 565w of the wall.
So my question is, would it be okay to connect 2 S5's to the one Corsair 1200w Platinum PSU ?

Thanks !





https://bitcointalk.org/index.php?topic=902305.new#new

The load will be closed to 93%, but yes it's will work since the psu is platinum.
You can underclock if it's fail  :D

That would load the AX1200i to 86% which makes it around 91% efficient and leaves you with a 14% headroom.  That's really up to you if your comfy with that.  However, you do have a Platinum PSU.  I'd try it out and closely monitor it for a day or two and see if something is unusually heating up.

Edit:  Sorry...I got dyslexic there for a bit.  It's 84% load with 16% headroom and not 86% load with 14% headroom.  ;D

If I were you I would connect 2 at freq 343  run 6 hours .
  IF ALL IS WELL
 clock the  two at 350 run 6 hours
IF ALL IS WELL
clock the two at 356 run 6 hours
IF ALL IS WELL
clock the two at 362 run 6 hours
IF ALL IS WELL
clock the two at 368 run 6 hours
IF ALL IS WELL
clock the two at 375 check every 6 hours.

Thanks for the answers, i will try it out then :)

And one more question about the fan, what if i do no care for the sound ( they are in e different place ).
With what fans could i replace the stock ones for better cooling ?

I have a fan mod thread.


https://bitcointalk.org/index.php?topic=927941.0;all


links are in it.  the deltas allow  for fast clocks  and lower sound then the stock.    but this post spot interests me


https://bitcointalk.org/index.php?topic=902305.msg10296057#msg10296057

he has an older dead fan gutted attached to the s-5 then the stock fan without a grill (watch your  fingers)  he has good sound results

Looking at the description of the Silverstone 141 there is no mention of it being PWM, only that it has a "PWM header" (ie. 4 pins).  Looking at the fan wiring, I only see three wires -- again indicating not PWM.

So what convinces you that it's PWM?

I installed  and used about 10 of them they run as pwm. you need to doctor the plug a little to make it fit. (shave a small piece of plastic and it fits on the s-5 4 pin header.

I have another thread about final fan mods. I will look for it.

An s-5 with a silverstone 141 pwm fan as the pull and a delta 1212 pwm fan as the push is pretty good for sound and cooling. I just gave up on the entire s-5 line due to pricing ups and down along with the need to do a fan mod or 2 to keep them quiet.

So, you're saying there actually are four wires going to the connector?  Or are you saying the controlled speed of a PWM push fan has the effect of modulating the speed of the pull fan?

PS. A fan can't be PWM controlled without both a sense wire and a control wire.  If less than four wires, no fan can be PWM.

this is a four pin pwm fan. it will scale up and down with your clocking of the s-5. used as a pull with a four pin  delta the s-5 is a nice miner.

I like alot s5 that is my first miner i have connected to corsair 850 rm and is perfect!I will keep buying them!
Just to share my experience for those they are looking to change the fan as it is too loud, i have changed it with two corsair sp120 High performance pwm direct on s5 and the results are amazing it is really silent, running at 2160 and 2040 with temp usually stable at 67-69 but some time it goes to 71-72 for couple minutes.I have underclock it at 312.5 and hashing 1050GHS to 1200GHS but i am really pleased with the sound now!

Kind Regards,
BTC-Bank.

That temp is faaaaaaar to high, you're miners will die sooner or later with those temps, 60 is allready very hot....

Thank you for the tip @Furio!Other says it is ok and other that i will have problem on other threads too.
Anyway i know that this isn't the best temp, before i change it was 58-60 temp after 24 hours with the standard fan.I have order 2 more corsair af120 silent to add direct on the psu and put them under the miner, that it will help a lot!I know it is too much but i have the silence i want now. :)

Kind Regards,
BTC-Bank.

just drop the clocks to 275 you don't need more fans then 2.

Thank you for the tip @philipma1957!I have follow your advice and i have drop the clock to 275 temporary until i receive the fan i ordered.The temp is now 64 - 65 and mining at 950GH/S +/- for the first 10 minutes.  8)

Kind Regards,
BTC-Bank.
