Inleiding

Use this guide to replace a damaged heat sink or its thermal paste.

    • Shut down and close your computer. Lay it on a soft surface top-side down.

    • Remove the following ten screws:

      • Two 8 mm 5-point Pentalobe screws

      • Eight 2.5 mm 5-point Pentalobe screws

    • The special screwdriver needed to remove the 5-point Pentalobe screws can be found here.

    When you say:

    Remove the following ten screws:

    Two 8 mm 5-point Pentalobe screws

    Eight 2.5 mm 5-point Pentalobe screws

    Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

    Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

    Nerdily yours,

    The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

    I sourced all the parts from ifixit, plus a magnetic project mat which I found to be very useful for organising the teardown and reassembly.

    Keep the 2.5mm tiny screws away from the MagSafe connector as they will be attracted and sucked in to the magnet.

  1. Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.

    • In this step you will disconnect the battery to help avoid shorting out any components during service.

    • Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

    • Bend the battery cable slightly away from the logic board so the connector will not accidentally bend back and make contact with its socket.

    When reassembling the connector wire needs to be bent to fit.

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

    • We recommend you gently "walk" the connector out of its socket.

    • Peel the iSight camera cable up off the adhesive securing it to the fan.

    • Use the tip of a spudger to carefully flip up the retaining flap on the fan cable ZIF socket.

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

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

      • Two 5.5 mm T5 Torx screws

      • One 4.6 mm T5 Torx screw

        • In some models this is a 3.6 mm T5 Torx screw.

    • Lift, but do not remove the fan out of its recess in the upper case.

    • Carefully pull the fan ribbon cable out of its socket as you remove the fan from the Air.

    • Remove the four 2.5 mm T5 Torx screws securing the heat sink to the logic board.

    • If the heat sink seems to be stuck to the logic board after removing all four screws, use a spudger to carefully separate the heat sink from the face of the CPU.

    • Remove the heat sink from the logic board.

    • When reinstalling the heat sink, be sure to apply a new layer of thermal paste. If you have never applied thermal paste before, we have a guide that makes it easy.
