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