Description Spare part number
Fan sink 657402-001
The fan sink is secured atop the processor with four captive Torx screws. A fan cable connects to the
system board.
1. Prepare the computer for disassembly (
Preparation for Disassembly on page 104).
2. Remove the access panel (
Access Panel on page 105).
3. Loosen the four captive screws that secure the fan sink to the system board tray.
CAUTION: Fan 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.
