Wow thats a big GPU mining setup

How do you do thermal management of your home?

That's only a portion of it. Wink

71Ghash total.

Maintaining thermal management without making it too hot/cold has been a learning experience.

I've been doing it for about a year and a half now though.

That's epic my friend

I'm running a Gigabyte GV-R797OC-3GD and I've been happy with it. Topped out at about 1100 MHz on stock voltage. No problems regarding thermal management, but I'm running a good amount of case air flow. The video card is quieter than the case fans in my instance.

I have 25 of them and they all stay cool/quiet.

Use these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102982&name=Desktop-Graphics-Cards

They are a reference PCB, but they have a better heatsink and quiet fans. I have 25 of them and they all stay cool/quiet. I would not recommend them if you're going to put them inside a case though (it'll be difficult to vent the heat). If you're going to do that, stick with a reference cooler.

The Gigabyte cards and Powercolor cards that use 3 fans have their own proprietary method of sending fan RPM readings, so programs like CGMiner that read & control fan speed from ADL will give crazy readings for them (like this):

Also, most of the Gigabyte cards with "WINDFORCE" coolers (like the one above) use *very* cheap fans and they tend to lightly rub on the fan shroud. The cooler is effective, but the fans are crap. I was sick of dealing with it, so I sold all of mine (the Gigabyte cards). They usually work fine if they're mounted upside down in an ATX case though.

My Gigabyte WINDFORCE Tri-fan doesn't have that issue. Cgminer correctly reports it as set to 70%, 3430RPM.

Something with double or triple fans

not only do the fans spin slower (so quieter) it gives you backup should a fan go down.

Thanks for the reply. Yeah, I've been hearing good things about Gigabyte and MSI Lightning. Voltage over/unders, memory downlocks, and good VRM cooling.

Gigabyte's been making some really good shit the past few years, GPUs or anything else. My brother's also got a Gigabyte 7770, factory OC to 1100MHz, and it's also rock solid, and very cool.

I have this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125439

I've always preferred reference coolers, as the main heatsink directly cools the VRMs, but I went with this one. I ended up putting little aluminum RAM heatsinks on the back of the VRMs, cuz they were getting too hot. That's the only issue I've had, and once I got past that, it's the best card I've ever owned!

I can overclock it to 1200MHz, even with my low ASIC quality. I normally run it at 1050MHz @ 1050mV, tho.

You can't hear the fan < 50%. I normally run it at 60-70%, and it keeps my core between 55-60C, and my VRMs around 65-76C, depending on ambient.

What's the best 7970 out there that keeps things cool enough for a good overclock, and who's fans aren't as loud as the 6990s I used to have.

I know asking for good cooling at load and for them to be quiet is quite the request, but I just wanted to get an idea...

Thanks!
