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?

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?

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.

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

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.

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.

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

Good idea, thanks!
