replaced, use the thermal pad provided in the kit to ensure that thermal
conductivity is achieved.
1 Clean the thermal grease from the bottom of the heat sink and reapply it.
2 Align the screw holes on the heat sink with the screw holes on the
system board.
3 In sequential order (indicated on the heat sink), tighten the captive screws that
