The Sound Of My Notebook's Fan Is Too Loud; Why Does The System Properties Dialog Box Display A Slower Cpu Speed Than Advertised - Sony PCG-FX410 Primary User Manual

✍
If this procedure does not work, press and hold the power button for four seconds or
longer to shut down the notebook.

The sound of my notebook's fan is too 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.
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, System Properties may display the CPU's current speed
instead of the maximum advertised speed.
