7. Lift the failing heat sink and fan assembly off the system board.
Notes:
a. You might have to gently twist the heat sink and fan assembly to free it from the microprocessor.
b. While handling the heat sink and fan assembly, do not touch the thermal grease on the bottom of it.
8. Place the new heat sink and fan assembly on the system board so that the four screws on the heat sink
and fan assembly are aligned with the corresponding holes on the system board. Make sure that you
properly place the heat sink and fan assembly so that you can easily connect the heat sink and fan
assembly cable to the microprocessor fan connector on the system board.
