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.

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

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

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)

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

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? Roll Eyes

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.

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.

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

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

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.

Personally I think the Tube was a great, great layout to remove 900W with 1 fan. And that was coming from the Cube which again, raised the bar of what you can do with a silent 120mm fan (350W).

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

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
