Heat dispersal

To protect from overheating, the processor 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 processor temperature by 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. These functions
are controlled within the Power Options.
When the processor temperature falls to a normal range, the fan is turned
off and the processor operation returns to standard speed.
If the processor temperature reaches an unacceptably high level with
either setting, the system automatically shuts down to prevent damage.
Data in memory will be lost.
