The heat sink and microprocessor might be very hot. Make sure these
components are cool enough to safely handle before continuing this
procedure.
1. Remove the cover. See "Removing the cover" on page 89.
2. Lift the fan duct off the heat sink fan.
3. Disconnect the heat sink and fan assembly cable from the system board. See
the system board illustration for your machine type at "System board
connectors" on page 88.
4. Remove the four screws securing the heat sink and fan assembly to the system
board.
5. Lift the heat sink and fan assembly off the system board. Place the heat sink
on its side so that the thermal grease does not come in contact with anything.
Note: You might have to gently twist the heat sink to free it from the
microprocessor.
