4Loosen the four captive screws that secure the heat sink to the system board. (Two screws on the far side of the heat sink are not visible in the following photograph.)

Caution

The heat sink has Thermal Interface Material (TIM) on the bottom. Be careful not to damage this material when you remove the heat sink from the processor. If removing the heat sink also pulls the processor out of the processor socket, the processor could be damaged.

Screws

5Remove the heat sink. If the heatsink sticks to the processor, rotate the heatsink slightly to loosen it.

6Place the heat sink over the processor, lining up the four captive screws with the four posts surrounding the processor.

Caution

The heat sink has Thermal Interface Material (TIM) located on the bottom of it. Use caution when you unpack the heat sink so you do not damage the TIM.

7Loosely screw in the captive screws on the corners of the heat sink, gently tightening diagonal screws (screw in one screw, then the screw located diagonally to the first screw). Do not fully tighten one screw before tightening another.

8Gradually and equally tighten each captive screw until each is firmly tightened. Do not over-tighten the screws.

9Connect the new heat sink fan’s power connector to the system board.
