Are there any pc cases that would fit 2 antminer s1 in it? I wanted to know because my Local Datacenter requires it in a enclosure. If any body have any good ideas let me know thanks!

Your local datacenter likely uses 19" racks

Get a rosewill 4U RSV-Lxxxx Case:

Rip out all of the guts including the front and rear panels.

Screw it into the rack.

Good to go.

The short rosewill might work, I haven't used though so check the dimensions.

The Cabinet is a G2 HP 42U Cabinet. What kind of Rails do you recommend for this case?

I totally appreciate it, you are a great person!

I'm lazy, I usually just screw them into the rack from the front panel.

The rails for these cases are about $20 a shot from newegg.

Is it difficult to remove the guts (the internals), is easy to unscrew it and take apart? And what do you mean by ripping out the front and back panel? Do you mean take out the fans harddrive cages?  And by screwing in the front panel to the cabinet will it hold the rosewill case good? Thanks I appreciate your comments.

And now for something completely different.

So when the web interface says 45C, they're really upwards of 80C?

It's a bunch of little screws.

I remove:

The top button panel (power button etc)
The hard drive cages
The metal that holds in the hard drive cages
The rear panel (Pci slots, fan slots PSU mount) it's all one piece
The motherboard tray
The rear support bar/cable tie bar
The inner front panel mesh
The inner front panel mesh holder.

That is all.

They work fine with no rails if you have a full rack.

I suppose if you stick it in the middle of empty rack it may sag a bit.

And now for something completely different.

BadAss.

I put the same fans, 1 on each side and found that at the expense of sound, when OC'ed to 400Mhz, it still runs warmer and doesn't get close to 200Gh/s like the other Ants running the stock fans. Do you have the same results?

The unit in left, my original runs 205 the other 2 run around 195. I dont think its the temps. Some units just OC better its the overcloking facts, some chips perform better.

I got no diffrence when tested each unit with single psu so its no power issue. Some overclock better.

I guess so. I thought the thermal specs on the chips were much lower than 80C.

Question here:
Wouldn't the machine just shut down when it reaches a very high temperature?

I found the best results by placing fans on the outside, blowing on the chips, exactly where the images show they are the hottest: https://bitcointalk.org/index.php?topic=443718.msg4920949#msg4920949

OC @ 400Mhz and HW around 0.6%

I would hope so. GUI still stays under 50C.
These pictures were taken at stock too and were stable for a week.
I OCed them last night and they're still going strong as of right now.
I'll check the temps again. I'm curious to see if they went up at all after a bump to 375.

Just having a look round and managed to group some really nice Ant setups:

[philipma1957]

I have 4 with 2 fractal 1000 watt platinum psu's and 2 ups units from eaton along with a 16 port switch from trendnet



setup gives 720gh for 1460 watts  and has the ups backup

How much does that actually help with airflow and cooling?  I am seriously considering this, but don't know if it actually helps or is just a bit gimmicky...

it definitely helps. However, there is a tradeoff between the extra fan cost ($15 for a good one with >70cfm) and how much more you will mine by overclocking an extra 5-10GH.

[the-skeptic]

Two of my six Antminers. I've made custom covers for all of them, which helps force a lot more air over the heat sinks and chips.

My brother actually suggested that i should do the same about a week ago.

He said it will work out much better to reduce heat that way.

So, how is it going?

EDIT: Doesn't the hot air coming out from one Ant affect the heat of the other?
I mean because you have them facing the opposite direction.

New Update. In my non-climate controlled 2-car garage I have three S1 Antminers overclocked to 393 MHz. The temperature here in Santa Fe, New Mexico is 62F/17C, but the three miners bring the temperature up to a cozy 89F/32C inside the garage. I ran one miner for 8 hours without my custom cover, which then reported temperatures of 54C/57C in the "Miner Status" tab. After 30 minutes with the cover on the temperatures had dropped to 51C/53C, and after 45 minutes the temperatures had dropped to a stable 47C/50C. This equates to a 13 degree Fahrenheit drop on both boards.

I will be selling an improved version of the case within a week, with the price point in the .017 BTC range for quantities under 10, and ~.0155 BTC for 10+ units (based on the current exchange rate). The price will include UPS ground shipping with tracking inside the USA for orders of 10+, while smaller orders will be at a flat rate of .009 BTC for UPS shipping.

Has anyone tried a liquid-cooling solution? I was thinking it might bring down weight and noise a lot...

I would love to see bitmain do this in the S2.

however, from an end-user POV there are two issues I see:
1) cost of building custom waterblocks is high, probably more then what you would save over air cooling (maybe $25/month) and by getting the extra 5-10GH (~$50), particularly in small quantities
2) you could try immersion cooling similar to asicminer, but the initial costs for that are very high (You would probably need to spend a few thousand in r&d to have one designed for 1TH or so)


In bulk, the prices could be reasonable. I'm sure bitmain could have custom waterblocks made in china that weigh a little more then the current heatsinks for an extra $10 each.

Add in hoses, pumps, and a radiator - you could build a 1TH antminer that takes up about the space of 3 S1 units (weighing about the same as 3 units) and requires only 2 fans on a decent radiator. The final cost might be achievable at a 5% premium over current costs.

I can envision having an antminer where a pair of big waterblocks measuring about 10"x10"x2" (about the size of two of the current heatsinks stacked vertically) could have 4 blades bolted to each it and would only require about the same amount of space as 2 antminers

{[]} {[]}
{[]} {[]}       {,} represent hashing boards    [] represents waterblock
  |\   /|
[radiator]

however, the design costs for this would probably outweigh the benefits up until at least making >100 of them. There would also become the risk of liquids in your mining farm if build quality is lacking or hoses get pulled loose

Best way to lower noise and heat output on these bad boys?

Turn them off.

[precrime3]

Best way to mitigate noise/heat while they are hashing at default speeds, my bad it seems I did not clarify.
