68 Replacing the Heat Sink Assembly
CAUTION: The processor heat sink is attached to the processor fan shroud. When
you remove the processor fan shroud, lay it upside down or on its side to avoid
damaging the heat sink thermal interface.
CAUTION: Ensure that adequate thermal grease is applied to the top of the
processor. Thermal grease is critical for ensuring adequate thermal bonding,
which is a requirement for optimal processor operation.
