Use this guide to replace a broken or noisy fan.
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.
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.
Use the flat end of a spudger to pry the left and right I/O board cable connectors up off their respective sockets on the I/O board.
Lift and remove the I/O board cable.
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.
