 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.

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!!!

next photo I got some screws from lowes

you can get the short ones


and not use the long ones





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



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

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

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.

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.



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.

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? Huh

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.

http://www.ebay.com/itm/Switching-Power-Supplies-100-8W-9V-11-2A-Power-Supply-/171616908246?pt=LH_DefaultDomain_0&hash=item27f52a33d6

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

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.  Tongue

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  Tongue
