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.

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.

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.

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.

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.

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.

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!

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?

Anyone know the model of the stock S5 fan? Also, do they make a PWM adapter that goes between the fan and connection to undervolt/clock the fan a little? The fan is working too hard, temps are 49-50, I could lower the RPMs a little to get it a little quieter. Also, how many watts/amps/volts can we pull from the fan connections on the controller board? The fan on there must be pulling like 4-5 watts, right?

I don't see anything to do with bitmain, maybe because their ddos protection kicked in and is working?

Where do you see that reward?

Not that simple. Some attacks only last an hour, not days. It all depends on how the system admins know what they are doing. Can't just put a caching service up and say you are protected. Need to log into the server itself, review the logs and know where to look to find the right solution. I have no idea what kind of service Bitmain uses to run his site. His own server or has it hosting somewhere. But if an attack renders your site useless for a few days and you have tried all that you can then you need to hire some big boys to take over and clean house.

They are sitting on a flat surface already. I guess I can try taping the bottom and top heatsinks and see what happens. I do like to keep them running at 60 or below, since we really don't know the real temp of the ASIC chips. Do you know the max temps of the ASIC chips on there? The sustained temp?

Let me get on your server....I'll have them running away in 20 minutes, because every packet that makes it back will contain malware for their computer, not to mention being automatically blacklisted on the firewall for 6 months. Yes, the entire subnet. Been dealing with ipchains and firewalls for years. Very good at Linux security.

Guys, the piece that comes with the EVGA is the female version. It will not plug into the modular power supply itself. You still have to hook up that bulky cable. That's why I bought those 24pin female plugs (couple posts above) so I can pull the power cable out and put back in the box. Then just easily plug that little piece in.

Am I beat here? I bought 6 S5's for $419 yesterday and now see them for $369. Bad business practice. I would cancel my order if I could get into my account. And if there are any left then so be it. If not then it was never meant to be. I've never never been money sucked that bad in a long time. Probably comes out to a $350 difference.

Using two SP120's temps rose to 65c right away, and it was cool in my house. Soon as the warmer months come that S5 will fry up. Used two Noctua 3000 and temps were 10c less in same room. Nothing special at all about the Corsairs.

I flashed my C1's and they all work exactly as they did before except they have the newer cgminer running. I did not author the software, so I can't give you specifics.

Anyone know what model the stock fan is on the S5? And if they are any other 35mm fans out there that can keep the S5 cool at ambient temps?

Also don't waste your money on getting the Corsair SP120 fans. While they are quiter than the Noctua's the temps will rise over 60c pretty much %100 of the time.

If any of the current deals fall through I will contact the users that have messaged me.
All C1's are operating fine and have been well taken care of. All have upgraded pumps, Feser One coolant and siler kill coils in both the in and out lines. They all have been flushed a couple of times until I found the perfect combination of coolant and silver.
