WARNING: The heat sink may be hot to touch for some time after the system has
been powered down. Allow the heat sink to cool before removing it.
CAUTION: Never remove the heat sink from a processor unless you intend to
remove the processor. The heat sink is necessary to maintain proper thermal
conditions.

screws. See Figure 3-19.
Wait for 30 seconds for the heat sink to loosen from the processor.
