^its unfortunate - It was actually a pretty good setup they had, but the fault protection was the real issue. It took hours for the fire to spread, and the staff were BOTH SLEEPING. electrical fires are otherwise easy to stop if you or a protection system trips the breaker.

The sheer density is boggling - not necessarily unsafe, but I would have personally maxed out at about half as many units per 'stack'

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

My small setup! around 3.5 TH  Grin

1 S5 - 1 Avalon4.1 - 1 SP20




What is the white large hose doing behind the S5? Exhausting the hot air? The stock fan on the S5 keeps it cool without any additional fans. Maybe overclocking?

Just boxed up Corsair CX750M's and pulled the stock fans out of the S5's. Replaced those with Corsair SP120 fans. Replaced PSU's with an evga 1300G2 Supernova.

Right now window cracked open - running cold air intake mode! Once I figure how they will rest will secure them then get on that red cable management. What a mess.

Couldn't be happier with the new fans or the new power. Love these machines, especially now that they are liveable and silent compared to stock.




I ran the SP120 High performance on my S5's and they couldn't cut it. Ambient temps were about 65F and the temps went straight to 65 or higher. Soon as the warm weather sneaks in, those fans will not be able to cool it sufficiently. I opted for the Noctua NF-F12 3000. Used two of them on each S5 and brought the temp back down 10 degrees. A lot less noise than stock fan, but not silent either. In between, but dooable in situation.
Good luck!

Its a better solution than paper clip!



That would be nice to have when your power supply isn't %100 modular and the power cables were built into the power supply. But when you have a main power switch on your power supply, I'd rather use the paper clip and the main power switch. Having two redundant switches doing the same thing would confuse some people after a few beers. Smiley

image of the antminer clip-on

I have and prefer this method, looks much cleaner!
I have a lot of dully-modular supplies. The EVGA can be paperclipped directly at the back of the PSU and you wont have a fat 24pin cable getting in the way at all

I hate to ask... as I've got a number of these Antminer kill switches / paperclip replacements... but how do you paperclip the evga 1300 G2 "at" the PSU? Because honestly unplugging that huge 24pin cable and putting it back in the box would clean things up that much more.

Then again... arranging, re-arranging my miners is as much fun as mining itself. I had a rack of S1's and went through a few summertime setups trying to get rid of the heat. Absolute insanity hearing 5x PSU's running AND the A/C unit running non-stop. Anyway, here is basically the reverse of what I've got going now.



You need this 24pin connector. Just install the correct pin placement and plug it right into your power supply where you would your big ugly power cable. I do it all the time.

Its fresh air from outside to keep the fan as low as possible for the sound. The S5 is in my livingroom with 2 delta fan. They run at about 2000rpm.

Runnung in cellar @ 1,3THS - thanks bitmain! Heating up the room to 26C  Grin
Cores running on 52 and 49 derees
Ethernet cable to repeater on top
One S5 heats up your whole cellar?  How loud is it?  I'm thinking about getting one.

The S5 stock fan probably blows at 250CFM, and is loud. If you put your hand behind the miner you can feel the push of the air really well from that one fan. If the ambient temps are 60-75F I would imagine the fan runs at 3000-3500 rpms and  keeps the temps 48c/49c which is exceptionally good. If I can find a 4 pin fan underclock/undervolter I would give it a try. The stock fan is working way too hard when it doesn't need to. About the noise. If the S5 is in line of sight to your eyes you will definitely hear it and it may bother you after a while. But if it is in another room that is across another room with a turn where you can't physically see the miner then it sounds completely different. Much more tolerable on the ears. Either way I'm replacing all my stock fans with the Noctua NF-F12 Industrial 3000 model. One fan one each end in a push pull config. Take about 20 dB away, but is not silent but MUCH more tolerable. And if in a basement you may not even hear it.

P.S. do not insert filters or anything like that. That will restrict a lot of air flow on any fan. Just don't be lazy and keep your rigs clean. When they need a cleaning, I take them outside and use my air compressor to blow them down and dust them off. Shiny like new.

Pokey, did you tape/cover the bottom fins on those S5's? Lots of air escapes from the bottom if you put them on a bread cart type cart. Can easily use blue painters tape or something. Not talking about a huge difference in temps, but a difference. And every temperature point counts for the life of the miner.

Not to worry,cable management is no longer a problem......that rack & 2 more warehouse's burned,they think arson,but never heard back about it.

http://qz.com/293418/an-enormous-bitcoin-mine-went-up-in-flames-affecting-the-entire-network/

Very sad  Cry
Firstly I wanted to ask how you were sure that it is the same one, but then I recognized the picture. Damn.
I hate when things like these happen. It's sad for multiple reasons. Has the poster of the image responded to this on the forum?

When you ask Spondoolie about it they always come back with, "Can't talk about it, NDA". So who knows, if they are silent about a mining center going up in flames with their products in it, kind of makes you think a little. I don't think anything was insured and the owners lost everything. If it was arson, that's really terrible.

All of that would fit in 1 42U rack. Why wouldn't you rack-mount rack-mountable servers?

Why concentrate the heat and power when you have a large clean open warehouse to fill?

There is no chance of water here? Power on the floor like that is so scary in an industrial environment.

I know what it was! It was the sun reflecting off that floor that started the fire. Sorry, don't mean to joke, but that floor must be the cleanest, shiniest floor I have ever seen in a data center.

I wanted to try other Delta's also. What model(s) did you get and try? Are you using the stock fan plus another 38mm as the pull, which is a Delta? Which model? There are so many.

Even though I'm switching to Noctua's I'd still love to try and slow that stock fan down a little bit. Working harder then it needs to. Slower fan = less noise.

If you check on this thread : https://bitcointalk.org/index.php?topic=907219.280


You will see you need Delta AFB1212SHE

Push pull setup with 2 delta is perfect.

I have not, but I'm very interested in learning more! Please, educate me. Looking at it again, you are talking about sealing the bottom to get more air pushed through instead of having it dissipate out of the bottom. What materials do I have here at home suitable for this that won't catch on fire? Smiley Also guessing a single board or similar that all sit on flatly would do the same trick.

Also, have a fan behind them blowing air out, creates nice air flow at the intakes.

Luckily hit the jackpot connecting with an old friend lately. He's got dozens of fans and controllers and all that good stuff. Soon will have high end fans in a push pull with speed controllers. All at the best price possible!

thanks opentoe!

Doubt theres anywhere in the vicinity water could come from - but i do agree with you. getting some of those power bars an inch or two off the floor would be slightly safer, though very little difference in the long run if the facility has no water sources nearby

Here in the US, I'll bet that's a $20-30 item at Target, a major retailer. I don't think they anything special.

+1. you can get some pretty decent metal shelving units with wood/fiber panel surfaces and a 400-800 pound capacity for $40-60

life is WAYY easier when you have almost 20sqft of surface to hold heavy units or lots of power supplies.
