    • Bend the connector back toward the battery, ensuring that the battery connector doesn't accidentally make contact with the logic board.

    • Peel the left rubber cover up off the fan and fold it out of the way.

    • Remove the following three screws securing the left fan to the logic board:

      • One 3.6 mm T5 Torx screw with a wide head

      • One 5.0 mm T5 Torx screw with a 2.0 mm long shoulder

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Lift the fan and push it gently towards the back edge of the MacBook to free the fan cable from its socket.

      • The fan cable may be adhered to the logic board—to avoid tearing the cable, gently peel it up while lifting the fan.

    • Remove the fan.
