About this task
NOTE:
The heat sink may become hot during normal operation. Allow sufficient time for the heat sink to cool before you
touch it.
NOTE: 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.
