Heat Sink and Fan

Replacing the Heat Sink and Fan

 

NOTE: 

The original thermal grease can be reused if the original system board and 

heat sink are reinstalled together. If either the system board or the heat sink is 

replaced, use the thermal pad provided in the kit to ensure that thermal conductivity 

is achieved.

1

Follow the instructions in "Before You Begin" on page 7.

2

Clean the thermal grease from the bottom of the heat sink and reapply it.

3

Align the screw holes on the heat sink with the screw holes on the system 

board.

4

In sequential order (indicated on the heat sink), replace the six screws that 

secure the heat sink to the system board.

5

Connect the fan cable to the system-board connector.

6

Adhere the display cable tape to the heat sink.
