Why is the sound of my computer’s fan so loud?
The computer’s fan may be running at a high speed to cool the CPU. By lowering the CPU speed, you also lower the speed and noise level of the computer’s fan. If your computer comes with the PowerPanel™ utility*, use it to lower the CPU speed. If your computer does not come with the PowerPanel utility, use the power schemes to lower the CPU speed.
