The heat sink is secured atop the processor with four captive Torx screws. The heat sink does not
include a fan.
1. Prepare the computer for disassembly (
Preparation for Disassembly on page 165).
2. Remove the access panel (
Access Panel on page 166).
3. Remove the fan duct (
Fan duct on page 189).
4. Remove the front fan (
Front Fan Assembly on page 190).
5. In the order shown, loosen the four captive screws that secure the heat sink to the system board
tray.
CAUTION: Heat sink retaining screws should be removed in diagonally opposite pairs (as in
an X) to even the downward forces on the processor. This is especially important as the pins on
the socket are very fragile and any damage to them may require replacing the system board.
