Replacing the Processor Fan and Heat-Sink Assembly

processor operation.

4 Place the processor fan and heat-sink assembly over the processor.
5 Align the four captive screws on the processor fan and heat-sink assembly
with the screw holes on the system board.
6 Tighten the four captive screws that secure the processor fan and heat-sink
assembly to the system board.
NOTE: Ensure that the processor fan and heat-sink assembly is correctly seated
and secure.
7 Connect the processor fan cable to the system board connector, CPU_FAN
(see "System Board Components" on page 10).
8 Replace the computer cover (see "Replacing the Computer Cover" on
page 18).

on.
