Carefully replace the fan without bending or pinching any cables.

Use a Phillips #0 screwdriver to secure the three 2.5 mm screws.

Ensure the fan is aligned correctly before tightening the screws. Over-tightening may cause damage to the fan or mounting points.

To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.

Don't push on the cables themselves, or you may damage the connector.
