7970 hot hot hot!

Find somewhere else for your rigs..... My rigs are loud..... Multiple scyte high RPM fans... Lucky me it's not located at my house

wow... my 7970s have to be undervolted to keep temps under 80C.  i run mine at 975mhz 50% fan speed (noise is a concern for me)  its border line unacceptable.  im getting 575mh/sec each, sure would love to get 700 though...

Just beef your intensity, 575mh/s is kinda low

575 is about right for 975 core...

you running yours in a case? you probably need more cool air coming in if your seeing that high of temps. Also even a couple more mm between the two cards can make a huge difference if you can separate them. I run caseless though

Over the years, I've always criticized my uncle anytime he ran his computer with the side panel off, but I've noticed significantly lower temps on my home computer when mining by taking it off. This is with a Gigabyte 7970.

A few of my MSI 7950 Twin Frozr III's hit 82°C on hot days (+90°F).  I recently added a Thermaltake Water 2.0 Performer to one of them and it's now at 57°C.  Was hoping for a better result after hooking up MSI GTX 670 up with an Antec KUHLER H2O 620 (max temp is 46°C) but then I realized that the TDP on the 7950/7970 is a bit higher than Kepler.  I do have a Water 2.0 Performer Pro which is similar to an Antec KUHLER H2O 920 which I'm going to try on the other 7950.  Hopefully it will drop the temps a little more.

That's great, 1) I didn't know you could put a CPU cooler on a GPU! 2) How are the VRM temps on that?

I have to give all credit to this man:

Otherwise I'd be using zip ties and probably making a mess of things.   

The VRMs are still fairly warm.  The Twin Frozr III's have a metal plate that covers most of them with a thermal pad underneath.  They weren't cool to begin with, usually 80°C or more at times.  But right now they're reporting 51°C/77°C with a 120mm blowing at the side.  My reference 7970 has cooler VRMs -- 51°C/68°C.

The biggest pain is the copper shim you have to put between the block and GPU.  I went cheap and got a 5-pack of 20x20x0.5mm shims for $2 on eBay.  FrozenCPU sells something similar for $3.99+shipping.

Cool.... I don't think those all in 1 Eco cooler things would be all that great for cooling a mining card...
