removed from the heat sink, do not touch the thermal grease on the bottom of
the heat sink or set down the heat sink. For more information about applying or
working with thermal grease, see "Thermal grease" on page 92.
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.
