An Antminer S5 review by klondike_bar; the loud, affordable miner

[klondike_bar]

Im measuring at the PSU, not at the wall. and by measure, I only know what the SP20 tells me (i set it to 150W/cable) and whether the PSU trips (612.5W 12V rail, seems to trip at 625W+). Right now the SP20 is at 10% fan, 18/52/47 temps, and 1.195TH. noise is about the same as my S5 at 5V fan power, 56/62 temps, and 1.23TH

update: pushed the Sp20 to 8% fan and 155W per connector. PSU seems steady so far and volume is about the same as the S5. 50/55C exhaust on it with 1.21TH. Both peices of hardware are excellent and capable of similar specs when running at 1.2TH

I'm going to tune both S5 and SP20 to 700 watts each, and see what performance they get.

at the wall? Im guessing that would be 1.22-1.32Th on the SP20 and 1.25-1.35TH on the S5, thouh the S5 seems to max out on 12V at about 412.5MHz (~1.32TH)

Can you post the settings you use for the sp20 so i can compare and measure power on the wall.
I am in the eu, with 220-240 volt. I think we get a slightly higher effiency on the psu's
Was hoping bitmaintech start selling a 4 boards type like the c1, that would be very good for home miners
Even without a slight overclock they would be a great solution to avoid noise and would give me the ability to place it inside the house.
Luckily i have now 3 phase 35 amps so can feed more machines than i can afford

I sold the SP20 units, and dont have a killawatt. My estimates are based on wire/PSU temp (the CS650M gets quite warm over 580W, and very hot in spots at 600W+, same for the PCIe cables which get barely warm at a ~300W draw each), and the DC12V draw readings of the SP20.

for the SP20 my settings were similar to most people getting 1.15-1.3TH from the device at low fan speeds. As i recall;
start: 0.635 max: 0.655 wattage: 155 fan: 10% (cold air at inlet)
running like this said 150W draw per PCIe (so presumably 600W 12VDC)

[bronan]

Thank you yes the voltage settings is what i am looking at they run pretty decent
My psu's are 1 antec 1200 quattro which does not even get warm at all on cables or casing even at full speed of the sp20's
The other psu's i own are a recom 1600 watt which does get handwarm at cables and casing
I am wondering which miner is more efficient the s5 or the sp20, noise wise i think the sp20 is better after i heard the s5 run over a skype call

How good S5 with underclock ?
Ex can it work 800GH with only 300 watt ?

Thanks...

it could if you had a 300W 10.5V (approx) power supply

want to bring down the noise and the s5 fan do this it helps a lot.




Take a old 120mm fan rip the fan out just leave the frame remount the fan back on and wolla!! your S5 will sound like A s3 even runs cooler to.



I can sleep at night my wife is not beating me over the head lol lol. it worked for me and the best part about it its still the original S5 fan!!!

[opentoe]

Wait, you mounted a fan on top of another fan? Are they both blowing in the same direction? I'd love to buy 1 or 2 of these rigs, but I just can't have the noise. That's what I love about the C1's. Have to deal with a pump and coolant, but you can't even tell it is in the room. Runs Silent.

[alh]

So the net effect of this is to use a 120mm fan frame as a spacer between the original S5 fan, and the case itself? How did you stumble on this idea? If true, it's about the cheapest change I have seen mentioned for S5 fan noise.

[dog1965]

This started me out with the idea and the fact that I could not take the noise anymore.

http://www.silverstonetek.com/techtalk_cont.php?area=&tid=wh10_0061


then I thought how can I make the air more directional so I was looking at shrouds like this. This is what you use by the way not to fans.

http://pc.mmgn.com/Gallery/120mm-Fan-Shroud

Then I said wait a minute. So I ripped out a 120mm fan from a burnt out one that I found in my closet and just kept the hollow frame and then mounted the original S5 fan back on and WOLLA! noise is gone.

The trick is to add some space between the case and the fan especially with delta fans you cant have nothing to close to the blades not even a fan guard. only fan guard you can use is the one that came with it.

Take your hand and put it over the fan guard you see how much more noise there is.

It cost me nothing but time and now it sound like a s3 a tiny bit louder with the fan guard on but I am going to ad another shroud just to space the guard with the fan.

Brings down temperature as well.

I found this thread whilst searching to DE-NOISE the 3 Antminer S5's I have in my basement. Howling banshee's would be a better term for them... ;-)
So I looked at the interesting  pics to 'double' fan (shroud), but looking at the pics and the 120mm I have, it doesn't match. The fan I have is all around open, so there is no shrouding effect.
Spending hours upon hours searching forums and what not, I would just throw the towel and find me some good replacement fans, suitable for the job of cooling (summer coming soon) the S5 and cutting the noise from 65db to about 40.
Do any of you fellow miners have any suggestions?
I am seriously looking at this fan: Noctua NF-F12 industrialPPC 3000 PWM
but there are so many other brands/ choices like Corsair SP120, or cooler masters etc.
Does anybody have any idea what the stock fans value for CFM is?
I vaguely remember seeing something at 4:30 a.m that looked like 286 CFM...
That is a lot of cfm for an 'open' system.... I don't think a push/pull as in the S3 does any good.
I don't overclock at this time, and rather have under-clocking on my mind.
Recommendations would really be very welcomed, as well as opinions. (this water cooling thing is just not for me)

I also would like to know if the same fan solution would work in this bloody S4 that I got myself into. (These are definitely not 'home' mining friendly)
thanks

not to plug it, but i have a post in marketplace (computers) with the description and pics that describes what happen if you use the Noctua NF-12 3000rpm and Scythe ultra kaze combo. Much less noise, but NOT 40 dB, that's just bs from manufacturers.
Real life noise of that config would be ~55dB, but it is day and night in comparison with 72dB howling from the default fans- I used those for less than 24hr and by the end of the day my ears were ringing nonstop.

I searched the threads with 'all' your posts ... even 55db would be great. One of these S5's is 78db the others about 72ish. Why did the Scythe not work for you in the push setup? At 133 cfm it should do the same/better than stock. Rabinovich in another thread claims that the stock fan is 107 cfm?
I can't see any benefit of having push/pull with an open case. Why did you decide to go with that?
Thanks for your many informative posts though.... I did try the 'double' fan thing and it does not work for me at all....it's still 75db

btctalk ate my long post.
In short: somehow Noctua is better than Scythe in push-maybe because of the fan geometry (with larger central part in scythe).
I tried scythe for push, but temp was rising too fast to 65c, and scythe is not PWM, but Noctua is.
However, Scythe does help to lower temp in pull position.
Noctua alone worked in push, but only at 325 or 337.5mhz setting. I did not want temp to exceed 60-61C. I have ambient at 29-30, though. lower ambient might help.

Your ambient is more than warm, you have summer in your house...
I finally found your pics with the Noc/Scyth on your miners and see that you want to sell them, did you sell them already?

Whilst shopping for fans (some other thread had a user that was adamant that the Noc is not sufficient) I stumbled across a deal I just could not pass
up at 45 bucks. I am getting sometime this week a box of 18 used Delta AFB1212HHE-F00 with 4 pin connectors. Rated at 120 cfm, 2900 rpm it should be sufficient to quiet my basement down... And with 18, I can try push alone or push/pull on all my S5's with hopefully acceptable results....
Thank you for your replies, they gave me a good idea how to approach these 'vacuums'!!
Now I have to figure out if they would work on the S4 also. Right now with the guards off and the case open it is manageable (not really actually). I don't think I will ever go for another S4, but if this noise factor on the S5's is working out, I will get some more.
cheers

those deltas should work for you

Hello philipma,
thank you for your expert opinion. I feel much better now about the impulse purchase.

I read all about your experiments and downloaded all pictures you posted.That mod with the 4 pin floppy and molex connector is a keeper.

I found that other thread / guide about the S5's in vertical position and the improvement in cooling.
I will post there and ask you maybe another question or two....

These fans are different that what you have and everybody else it talking about though.
At least I will be able to rest easier tonight knowing that the deltas's might work to quiet down my little private basement airport. Thanks!!!

So you modded a fan shroud and it reduces the noise? Interesting. Do you have DB measurements?

yeah he has wanted me to test it ..  I was happy with the delta's but I should test it with the shroud.  one thing I did was find longer screws.  so the grill is about ½  inch  off the delta fan.

I was getting 55 db and 393gh with my 1 s-5 and said fuck it . it is good enough.  If you find longer screws and space the grill off the delta it does help. somewhere i have a photo of that mod.


here is the s-5 in a 85f garage running with a lot of sp20e's . numbers are good 1290gh  with 99.9922% good and 0.0078% bad  


 and I don't mind the noise as it is in the garage. I suspect the temps are high since we got to 44f today in NJ.

I would be interested in that as well. I tried the mod with a 120x25mm (his is for sure a 38mm) and it did not work.
I took the grill completely off...
