About this task
NOTE: The thermal heat-sink may become hot during normal operation. Allow sufficient time for the thermal heat-sink to
cool before you touch it.
NOTE: For maximum cooling of the processor, do not touch the heat transfer areas on the thermal heat-sink. The oils in
your skin can reduce the heat transfer capability of the thermal grease.
The following image indicates the location of the thermal heat-sink and provides a visual representation of the removal
procedure.
Steps
1. Loosen the four captive screws that secure the thermal heat-sink to the system board.
NOTE:
Loosen the four captive screws in the reverse sequential order mentioned on the thermal heat-sink [4 > 3 > 2 >
1]
2. Lift and remove the thermal heat-sink from the system board.
