new 7950 running hot - Page 2

Got it.

Anyways, this is unrelated, but I finally figured out where my "boost" switch is. I flipped it to the other one and my settings are still the same (950x1250). Even more strange is my box claims it has both 800 and 925boost. My card stock runs at 950. This thing is so confusing. Anyways, as an experiment, I took the side panel off and I have a mini fan blowing into the case and now at 5 min I am at 69c. So I knocked down a few, but nothing noteworthy. Mind you this is all stock, this thing surely will be very hot once I overclock it...

Those temps aren't anything to be worried about. My repasted Dual-X 7950s run into the 70s all the time. Granted, this is at 1100 core at 1.243v. Just keep it under 85 under full load and your cards won't sustain any damage or degradation. AMD themselves have confirmed this. Unfortunately, I don't have the link handy.

It all depends on how HIS preset the fan speed ratios.
Very likely it will stay around 70C, but get louder in the process.

If you're happy with stock performance then undervolt. Or overclock while undervolting.

I run my Vapor-X @ 1000MHz / 1.012V and my temperature never exceeds 60C and fan speed stays at ~45% with the default fan profile. It's pure pleasure to use.
My laptop runs louder under load than that thing.

I see, so I suppose it was all marketing talk then about these "ice" coolers. Still confused about why my boost switch doesnt work though.

But yeah, stock settings it performs fine(fps wise), so I guess I will try undervolting when I get home.

I still feel like my temps are too high though.

You bought more performance per Watt, not less Watts.

Compare your card to a reference HD7950. You'll appreciate your IceQ^2 :-).

You can also ramp the fan to 100% and have a cool running card, but what's the point? It's been already tuned for optimum noise/temperature performance.

Okay, so I did an experiment and found that case airflow isn't a factor at all. I currently have all my fans maxed out at full tilt would another I just added to my side window blowing air right at the card. At stock settings with kombuster, my temps are only 2c lower than when all my fans were on silent.

Take the side panel off your computer and test again. Also, if you have a premium fan on your GPU, you might be able to run it at very high speed without it being too audible.

Please note, some GPU's can run hotter than others based on their quality (Silicon lottery) or if the cooler or TIM is badly seated/pasted.
