Operating Basics

To protect from overheating, the CPU has an internal temperature sensor. If 

the computer’s internal temperature rises to a certain level, the cooling fan 

is turned on or the processing speed is lowered. You can select whether to 

control the CPU temperature by turning on the fan first, then if necessary, 

lowering the CPU speed. Or, by lowering the CPU speed first, then if 

necessary, turning on the fan. These functions are controlled within the 

Power Options.
When the CPU temperature falls to a normal range, the fan is turned off 

and the CPU operation returns to standard speed.
