About this task
The following images indicate the location of the processor fan and heat-sink assembly and provide a visual representation of
the removal procedure.
CAUTION: For maximum cooling of the processor, do not touch the heat transfer areas on the heat sink. The oils
in your skin can reduce the heat transfer capability of the thermal grease.
NOTE: The heat sink may become hot during normal operation. Allow sufficient time for the heat sink to cool before you
touch it.
