Operating Basics

To protect against overheating, the processor is equipped with an internal 

temperature sensor which activates a cooling fan or lowers the processing 

speed if the computer's internal temperature rises to a certain level. You are 

able to select whether to control this temperature by either turning on the 

fan first, then if necessary lowering the processor speed, or by lowering the 

processor speed first, then if necessary turning on the fan. Both of these 

functions are controlled through the Power Options.
When the processor's temperature falls within normal range, the fan will be 

turned off and the processor operation returned to its standard speed.
