Not saying i don't believe you, but i just cant imagine.
When i ran single GPU, my Sapphire 7950 Dual-X (by far, not the worst cooling around) on far less voltage, it reached 70 degrees easily after a good gaming session. That was still in my HAF case.
What is your ambient temp?
Edit: what resolution you play on?

My 7950 dual-x at 1150/1550 1.156V MSI AB (1.080V gpu-z load) hits 70-72C (fans an 100%) after a good session of BF3. And the ambient temps of the room are arround 20-21.

How is your overclock with these bios'?

I flashed to this and temps went down but couldnt overclock the memory as well, only stable at 1250.
I noticed that MVDCC went down to 1.5 and couldnt raise this in AB

A tad high for 100% fan speed, but around 70c on 1.156v sounds about right for a dual-x i think.

Can you upload your profile or write how you setup your radeon pro,i can't seem to configure it correctly...

Also, you seem to be capping yourself at 60FPS? That will take care of the rest.
Now I can understand your temps. The only thing left to wonder is that golden chip of yours, stable at 1250MHz with a real voltage of 1.09V. Golden, I say to you! :thumb.gif

Nono its not really 1.09. I also noticed this when I first installed HWinfo, it ALWAYS shows 1.09 and never changes. The Trixx voltage is the real voltage.

load temps - 59c
http://www.legitreviews.com/article/1862/13/
gaming temps - 53c. furmark - 63c. (open test bench)
the cooler is very good and can easily run the card at below 70c temps even when overclocked to 1.1 Ghz. thumb.gif

Cheers for that, although I am still at a cross roads between this card and the 7970 Lightning.
Is there much benefit of going with the Lightning? I know about the lack of dual link DVI and its somewhat putting me off.
But to use 3 monitors I am going to have to use a Display Port compatible screen anyway.
I will be going with crossfire at some point with either of these cards, so I want to ask, is the performance on the lightning worth the trade-off with the price and lack of dual link DVI?
Also what is the performance difference between 7970 crossfire and 7950 crossfire?

The Trixx voltage is and never will be "the real voltage". Trixx tells you the nominal voltage, the real voltage is always lower than that because of Vdroop. But Vdroop alone is not going to explain that much of a difference. Still, I'm absolutely sure there is no way you'll get VRM temps such as yours with anything even near 1.31V. Core temps, maybe with a really good contact to the heat sink and fan really high. But VRM, no way.

I believe in HWinfo, simple as that.

I dont think you understand what I was saying. The HWinfo voltage doesnt change, EVER. I can have my voltage set at 1.31V or 1.20V and it always shows 1.09V.
