2. Remove the fan shroud (2).

Heat sink
To remove the heat sink, use these procedures.
IMPORTANT: The bond between the heat sink and the processor can be very tight.
If the computer will turn on, before removing the heat sink, turn on the computer until it warms the heat sink.
Warming the heat sink loosens the bond between the heat sink and the processor, thereby making it easier to
separate them.
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 before removal. Inadvertently removing the processor can damage the pins.
Before removing the heat sink, follow these steps:
1. Prepare the computer for disassembly (Preparation for disassembly on page 21).
2. Remove the access panel (Access panel on page 21).
3. Remove the optical drive (Optical drive on page 22).
4. Remove the fan shroud (Fan shroud on page 38).
Remove the heat sink:
1. Disconnect the fan cable (1) from the system board.
