Remove the processor heat sink:

Following the sequence stamped into the processor heat sink, loosen the four Phillips captive
screws (1) that secure the processor heat sink to the system board.

Due to the adhesive quality of the thermal material located between the processor heat

sink and the processor, it may be necessary to move the processor heat sink from side to side to
detach it from the system board.

Lift the processor heat sink up and to the right at an angle and remove it from the base
enclosure (2).

Thermal paste located on the surfaces of the processor (1) and the processor heat sink

(2) must be thoroughly removed and replaced each time the processor heat sink is removed.
Replacement thermal paste is included in the processor heat sink and processor spare part kits.

Reverse this procedure to install the processor heat sink.
