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.

1Disconnect the processor fan cable from the system-board connector (FANCPU1). See "System Board Components" on page 15.

2Using a flat-blade screwdriver loosen the four captive screws that secure the processor fan and heat-sink assembly to the system board.
