Removing the Heat Sink

1 Turn off the system, including any attached peripherals, and disconnect

the system from its electrical outlet.

2 Open the system. See "Opening the System" on page 58.
3 Remove the cooling shroud. See "Removing the Cooling Shroud" on

page 60.

4 If required, remove the expansion-card riser assembly. See "Removing the

Expansion-Card Riser" on page 75.

WARNING:

The heat sink is hot to touch for some time after the system has been

powered down. Allow the heat sink to cool before handling it.

CAUTION:

Never remove the heat sink from a processor unless you intend

to remove the processor. The heat sink is necessary to maintain proper
thermal conditions.

5 Using a #2 Phillips screwdriver, loosen one of the heat-sink captive screws.

See Figure 3-8.
Wait 30 seconds for the heat sink to loosen from the processor.

6 Loosen the screw that is diagonally opposite to the screw that you have

already loosened. See Figure 3-8.

7 Repeat step 5 till you have loosened the remaining screws.
8 Gently lift the heat sink off the processor and set the heat sink aside with

the thermal grease side facing up.
