Fan Speed Limit?

My 4890 stock cooler never spins up higher than ~37% no matter how hot the gpu gets. I can manually set it higher but why the limit on the automation? During an intense Borderlands game the gpu got up to 71c and the fan speed was just 34%.

ATI probably does not consider 71C a dangerous temperature to their hardware
 
My HD4850 idles at 83*C - with a manual 45% fan speed.

71*C is no issue.
 
I guessed the problem was a hot video card. While playing Borderlands, sometimes the screen would freeze for a second or several and there would be a buzzing sound.

No he is spot-on, a single-slot 4850 won't even hit 100% fan until 104C, which is what it is rated up to. ~80C idle is normal for that card. Cards with two-slot coolers will see much lower temps.

FWIW single-slot 8800GT's weren't a whole lot better.

The key is that the hardware can handle the temperature.
