When I loaded GPU-Z I saw the idle temp was hovering around 80 degrees. I used the Catalyst hack to set fan speed to 30% and the idle temps dropped a good 20 degrees. At 30%, the fan is barely audible, but anything past that and it's easily the loudest thing in the case.

How did you do the 'Catalyst hack' to set the fan speed?

The fan is simply a POS, worse than the 2900XT's fan even though at full throttle its not as loud, allthough I think I will be happy with the performance of this card so I'll let it be happy and play my games with the music LOUD, I'll let it get up to about 95-100degrees untill I turn it up anymore.
