Why is the sound of my computer's fan so loud?
Use the PowerPanel™ utility to change the Thermal Control Strategy setting to
Quiet. This setting slows down the CPU speed. See PowerPanel Help for more
information.
To reduce fan noise
1 Right-click the Battery icon on the taskbar, and select Edit/Create Profiles.
The Profile Editor window appears.
2 If it isn't already opened, double-click the System folder in the right panel.
3 Double-click Thermal Control Strategy - Performance, and select Quiet.
4 Click the File menu, and click Save.
5 Restart your computer.
Why does the System Properties dialog box display a slower CPU speed than
advertised?
This is normal. Because your computer's CPU utilizes a type of CPU speed
controlling technology for power conservation purposes, System Properties may
display the CPU's current speed instead of the maximum speed.
