Installing New Heatsinks
If you are installing a new heatsink, do not apply new grease to either the heatsink or processor,
as the replacement heatsink comes with the full capacity of grease applied.
Note: When installing a new heatsink, be sure to remove any residual grease from the top edges
of the heatsink’s processor. To clean o the grease, do the following:
Remove the processor from its holder on the logic board. (See “• Processors” in this chapter.)
Using rst the lint-free cloth and then the alcohol wipe included with the replacement •
heatsink, carefully clean o any grease from the top edges of the processor. Be very careful
not to touch the silver-colored coating on the top of the processor and the gold pins on the
bottom of the processor.
Use the cloth to carefully wipe the top edges of the processor one more time to clean o any •
remaining grease.
