I call BS. Mine will not go over 72C OCd 1100/1400

52c on 1.3v without water or aftermarket cooling, i find that highly doubtful.

His card has huge heatsink on it so for gaming temps sound possible with fans high but I doubt temps are 52C under furmark load.


VRM temps are important too. Hot VRM temps will prevent high over clocks. Have to keep VRM temps as low as possible. VRM temps on over clocked HD7950 easily reach over 100C if not effectively cooled.

52c on 1.3v without water or aftermarket cooling, i find that highly doubtful.

Dead serious haha I myself was shocked at the temps. I play BF3 and my load temps are incredibly low. I backed my clocks down to 1150/1550 because Im getting another 7950 tomorrow to crossfire and well, I dont need it cranked as high as I had it on a 60htz monitor with crossfired 7950's and my load temp on the single WF3 dont go over 49C in any map.

Hold up Ill go take a screeny of my 1150/1550 and post it at 49C lol. You will also see my VRM's at 55C/56C.

Edit: apparently I cant take a screenshot and have it show Rivatuner OSD....... anyone know how else I can do this?

I am not so much interested in clock speeds, i'm more referring to 1.3v and 52c under max load.
What speed are your GPU fans running on?

What speed are your GPU fans running on?

65% is about the max it hits. this is a screeny I just took of 1150/1550 on 1.25V and its after about 10 mins of play. Top row on the left is temps, far right last 2 are the VRMS and the first % from the left is GPU usage then fan speed. The screenshot is crappy though I did the print screen paste to paint thing.... It was taken in fullscreen though



Edit: I dont take my temps from benching I take them from my daily use (BF3). I Believe in heaven bench I hit 60-62C at 1.3V

That sounds realistic for good air cooling.





My temps for my water cooled HD7950 under Furmark. (Hot stuff, only try it if you feel confident about your cards cooling)
16.5C Ambient Temps

Furmark 15 minute Burn in Benchmark

Yea my vrms don't go much over 62c even in heaven. I have a side fan that blows directly onto the card and I have my hdd cage removed now (picture in my sig rig hasn't been updated yet) so the air from the front 2 120's blows directly on the card as well. And since I'm running an H80 I don't get the heat floating around the case from a massive heatsync so all the air is fresh and cool.

And somehow i still doubt it, 52c on 1.3v... I have seen watercooled GPU's on those temps.
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?

1920x1080 with 4xmsaa ultra in bf3. Ambient is around 18 or 20c (at least. That's what our crappy thermostat says). Sapphires cooling isn't as good as gigabyte wf3 is. Refunded a sapphire 7950 for stock artifacting before getting the gigabyte and saw a good 5 or 6c difference.

Ok so I ran a Heaven Bench at 1250/1600 on 1.31V and took a screeny of the desktop. Here ya go. Excuse the snip of HWinfo it tend to reset itself for whatever reason so I snipped it before it did so, note it says 1800 memory max, this is because I was monkeying around with it trying to get the 1250/1800 to run in Heaven but had no luck so I backed the memory down to 1600.




Note that I dont even hit 60C at 1.31V. Eat your heart out.
