CAUTION: The bond between the heat sink and the processor may be very tight.
If the computer will power on, before removing the heat sink, turn on the computer until it warms the heat sink. Warming the heat sink lessens the bond between the heat sink and the processor, thereby making separating them easier.
Make sure not to pull the processor out of the socket when you lift the heat sink, especially if you cannot warm the heat sink prior to removal. Inadvertently removing the processor can damage the pins.
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 99).
2.Remove the access panel (Access Panel on page 100).
3.Remove the fan duct (Fan duct on page 132).
4.Remove the front fan (Front Fan Assembly on page 133).
5.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.
