Removing the Processor Fan and Heat-Sink
Assembly
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.
CAUTION: The processor fan and heat-sink assembly is a single unit. Do not try to
remove the fan separately.
1 Disconnect the processor fan cable from the system board connector,
CPU_FAN. See "System-Board Components" on page 21.
