Replacing the Processor Heat-Sink
CAUTION: Incorrect alignment of the processor heat-sink can cause damage to
the system board and processor.
Procedure
1 Clean the thermal grease from the bottom of the processor heat-sink and
reapply it.
NOTE: The original thermal grease can be reused if the original processor and
processor heat-sink are reinstalled together. If either the processor or the

ensure that thermal conductivity is achieved.
2 Align the captive screws on the processor heat-sink with the screw holes on the
system board.
3 In sequential order (indicated on the processor heat-sink), tighten the
captive screws that secure the processor heat-sink to the system board.
