Why is the sound of my computer's fan so loud? 1
If your computer comes with the PowerPanel utility, use it 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. On the Windows ® taskbar, right-click either the CPU icon or Profile icon , depending on the model you
purchased.
2. Select Edit/Create Profiles. The AC Power Profile Editor window appears.
3. Double-click System to open the System submenu if it is not already open.
4. Double-click Thermal Control Strategy - Performance, and select Quiet.
5. Restart your computer.
Why does the System Properties dialog box display a slower CPU speed than the maximum?
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.
Why don't my changes appear on the computer screen (LCD)?
You may need to refresh the computer screen. Press the Windows key and press D twice.
