Processor Fan and Heat-Sink Assembly
Procedure
WARNING:
Despite having a plastic shield, the processor fan and heat-sink
assembly may be very hot during normal operation. Ensure that it has had
sufficient time to cool before you touch it.
CAUTION:
To ensure maximum cooling for the processor, do not touch the heat
transfer areas on the processor fan and heat-sink assembly. The oils in your skin
can reduce the heat transfer capability of the thermal grease.
1 Disconnect the processor fan cable from the system-board connector
(FANCPU1). See "System Board Components" on page 15.
2 Using a flat-blade screwdriver loosen the four captive screws that secure
the processor fan and heat-sink assembly to the system board.
3 Lift the processor fan and heat-sink assembly out of the computer.
