1.Turn the system board upside down with the front toward you.
2.Loosen the four captive screws (1) that secure the heat sink to the system board.
NOTE: Due to the adhesive quality of the thermal material located between the heat sink and system board components, it may be necessary to move the heat sink from side to side to detach it.
3.Remove the heat sink (2).
NOTE: The thermal material must be thoroughly cleaned from the surfaces of the heat sink and the system board each time the heat sink is removed. Thermal paste is used on the processor (1) and the heat sink section (2) that services it.
