Removing the Heatsink Fan Assembly

WARNING:The heatsink becomes very hot when the system is on. NEVER touch the heatsink with any metal or with your hands.

1.Use a screwdriver to loosen the four screws on the heatsink.

Note: Plastic parts containing bromide have been highlighted with the yellow circle as the

above image shows. Please remove these parts and follow local regulations for disposal.

2.Disconnect the heatsink fan cable from the mainboard.

3.Remove the heatsink fan assembly from the chassis then lay it down in an upright position—with the thermal patch facing upward. Do not let the thermal patch on the heatsink fan assembly touch the work surface.

4.Use an alcohol pad to wipe off the thermal grease from both the heatsink and the processor.
