Fan sink
The fan sink is secured atop the processor with four captive Torx screws. The fan sink includes a heat sink and
a fan.
1. Prepare the computer for disassembly (Preparation for disassembly on page 19).
2. Remove the access panel (Access panel on page 20).
3. Remove the rotating fan duct (Rotating fan duct on page 49).
4. Remove the fan sink duct (Fan sink duct on page 50).
5. Disconnect the fan cable from the system board connector labeled CPUFAN (1).
6. Loosen the four captive Torx T15 screws (2) that secure the fan sink to the system board tray.
CAUTION: Remove fan sink retaining screws 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.
7. Remove the fan sink assembly from the computer.
When reinstalling the fan sink, make sure that its bottom has been cleaned with an alcohol wipe and fresh
thermal grease has been applied to the top of the processor.
CAUTION: Fan sink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly
seat the fan sink on the processor to avoid damage that could require replacing the system board.
Make sure to replace the fan duct. Failure to install the fan duct may cause the computer to overheat.
