How to Change the ATI GPU Fan Speed

PC video cards are very powerful, but this power comes with high operating temperatures. To combat this, video cards have powerful fans that cool the graphics processing unit (GPU) down. The fan automatically responds to changes in temperature in the card, speeding up when the chip is too hot and slowing down when the chip is cool. This can lead to a constant shifting in fan speed that some people find irritating to listen to. Manually adjust the fan speed to prevent unwanted variations in noise output. Modify fan speed on an ATI GPU from within Windows using ATI’s Catalyst Control Center.
