Removing the Processor Heat-Sink Assembly

CAUTION: Unless a new heat sink is required for the new processor, reuse the original heat-sink assembly when you replace the processor.

1Follow the procedure in "Before Working on Your Computer" on page 9.

2Remove the computer cover (see "Removing the Mini Tower Computer Cover" on page 19 or "Removing the Desktop Computer Cover" on page 21).

3Disconnect the heat-sink assembly power cable from the system board.

4Loosen the two captive screws securing the heat-sink assembly to the system board.

WARNING: Despite having a plastic shield, the heat-sink assembly may become very hot during normal operation. Allow sufficient time for it to cool before you touch it.

CAUTION: A strong thermal solution bond may exist between the processor and heat sink. Do not use excessive force to separate the heat-sink assembly from the processor to avoid damaging the processor.

5Rotate the heat-sink assembly outward on its hinges, away from the screw holes, detach it from the hinges, and lift it out of the computer chassis.

6Lay the heat-sink assembly down on its top, with the thermal grease facing upward.
