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. See “Removing the Side Panel” on page 31.
2. Use a long-nosed screwdriver to loosen the four screws on the heatsink fan assembly.
3. Lift the heatsink fan assembly off the mainboard.
4. Lay it down in an upright position—with the thermal patch facing upward, on top of the optical drive then
disconnect the fan cable from its mainboard connector. Do not let the thermal patch on the heat sink fan
assembly touch the work surface.
5. Use an alcohol pad to wipe off the thermal grease from both the heat sink and the processor.
