Use this guide to replace the fan.

Don't forget to follow our thermal paste application guide before you reinstall your heat sink.

    • Remove the following ten screws securing the lower case to the upper case:

      • Two 2.3 mm Pentalobe screws

      • Eight 3.0 mm Pentalobe screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

  1. Wedge your fingers between the upper case and the lower case.
    • Wedge your fingers between the upper case and the lower case.

    • Gently pull the lower case away from the upper case to remove it.

    • The lower case is connected to the upper case with two plastic clips near its center.

    • During reassembly, gently push down the center of the lower case to reattach the two plastic clips.

    • If necessary, remove the plastic cover adhered to the battery contact board.

    • Use the flat end of a spudger to lift the battery connector straight up out of its socket on the logic board.

    • Be sure you lift up only on the connector itself, not the socket, or you risk permanent damage to the logic board.

    • Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.

    • Carefully remove the rubber fan bumper from the edge of the heat sink.

    • The fan bumper wraps around the heat sink and fits into slots in the fan duct. During reassembly, be sure to fit the tabs into the notches in the fan duct.

    • Use the flat end of a spudger to peel the four foam stickers off of the heat sink screws.

    • Remove the following screws securing the heat sink to the logic board:

      • One 2.7 mm T5 screw (silver)

      • Four T5 screws (black)

    • Use the tip of a spudger to push on either side of the the iSight camera cable connector to walk it out of its socket on the logic board.

    • Peel the iSight camera cable off the fan housing to fold it out of the way.

    • Use the tip of a spudger to flip the tab on the fan's ZIF connector.

    • Carefully pull the fan cable straight out of its socket.

    • Remove the following screws securing the fan to the upper case:

      • One 5.0 mm T5 Torx screw

      • Two 3.6 mm T5 Torx screws

    • Lift the end of the fan closest to the display hinge and remove the fan from the upper case.


To reassemble your device, follow these instructions in reverse order.

I completed this guide and it was brilliant, so thank you Andrew Optimus Goldberg and your contributors! I have a question about the Macbook's heat post-installation of a new fan.

I replaced the fan last night, and put everything back together. Today, the new fan is responding well under activities that would previously make the fan extremely loud and cause intense heat to build up on the bottom right of the Macbook: so far so good.

However, it seems heat is now being distributed to the keys and directly below the screen, and I can even feel it underneath the trackpad, and this is from simply turning the Macbook on with no applications straining the CPU.

Is this something to worry about? Have I possibly made a mistake in my installation, or is this normal for an ordinary working fan?

Thanks for any help that may be given. Appreciated

Is the fan you replaced the original one with the exact same model? While im no expert on this stuff my guess would be that it distributes air differently. I hope it works out for you though.
