Processor Fan and Heat Sink Assembly

Replacing the Processor Fan and Heat Sink

Assembly

CAUTION:

When reinstalling the fan, ensure that you do not pinch the wires that

run between the system board and the fan.

Clean the thermal grease from the bottom of the processor fan and heat

sink assembly.

CAUTION:

Ensure that you apply new thermal grease. New thermal grease is

critical for ensuring adequate thermal bonding, which is a requirement for optimal
processor operation.

Apply the new thermal grease to the top of the processor.

Place the processor fan and heat sink assembly back onto the bracket.

Ensure that the two clamp grips are aligned with the two bracket

projections.

Hold the processor fan and heat sink assembly in place and rotate the

clamp lever 180 degrees counter-clockwise to secure the processor fan and

heat sink assembly.
