Disconnect the Fan's Power Cable: Locate the fan's power cable connected to the motherboard. Gently unplug the cable by pulling on the wire very close to the connector perpendicular to the board.

Unscrew the Fan: Use a screwdriver to remove the screws that secure the cooling fan in place. There are only three screws.

Note: Keep the screws in a safe place for reassembly.

Remove the Fan: Lift the cooling fan away from the CPU and motherboard.

Cooling bar system: Do not remove this, yet.

WARNING: The device directly behind the fan is the cooling bar system. This is attached to the CPU on the motherboard. Make sure not to damage the system.
