  • Disconnect the port hatch ribbon cable from the logic board by pulling it straight up by its black pull tab.

  • Pull the audio out ribbon cable off the adhesive securing it to the upper case.

  • Use a spudger to pry the audio out ribbon cable connector board off the hard drive bracket.

I skipped the step (6c) of prying the audio out ribbon cable connector board off the hard drive bracket (& disconnecting it), since it doesn't come off real easily, and I didn't want to damage it. It only requires a little more care when removing the HD from it's bracket if you skip step 6c.

  • Disconnect the audio out cable from its socket on the port hatch ribbon cable.

This is not necessary and looks pretty risky too.

Agreed, I encountered no issues when I skipped this on a Rev.B model.

Reversing step 8 is where I ran into trouble. The replacement fan I had was slightly thicker than the original and caused the ZIF cable to work its way out of the tenuous connection it had to the SSD, resulting in a "?" missing boot drive error upon startup. Took me three tries to get it right! The difficulty is to get the drive connector to the logic board to reach and seat without pulling the other end out of the drive.

There is a cable glued to the diskframe that must be loosened with a spudger before you can remove the frame.

  • If you have the original version of the MacBook Air (A1237), refer to picture 1. Remove the following screws securing the heat sink to the logic board:

    • One 5.9 mm Phillips screw.

    • Two 1.9 mm Phillips screws.

    • One 1.9 mm Phillips screw.

  • If you have the A1304 version of MacBook Air, refer to picture 2. Remove the following screws securing the heat sink to the logic board:

    • One 5.0 mm Phillips screw

    • Five 1.9 mm Philips screws.

    • One 2.5 mm Phillips screw.

On A1237, the yellow screw is a bit longer then the two orange ones.

I have replaced several Logic boards at this point on the A1304 model, and realized that I did not need to remove the heatsink (Steps 14 through 17). You need to remove the screws around the fan, and disconnect the microphone cable (step 19). Of course if your replacement logic board doesn't include a heatsink, you need to take it off.

  • Lift the processor clamp off the heat sink.

  • Deroute the microphone cable away from the channel in the fan.

  • Lift the heat sink up off the logic board.

  • Be mindful of the microphone cable when lifting the heat sink, as it can get tangled on the top edge of the fan.

  • When you mount the heat sink back onto the logic board, be sure to apply a new layer of thermal paste. We have a guide that makes replacing the thermal paste easy.

I removed the fan at this point as well. Disconnect the small connector from the fan to the logic board and lift out the fan. Good time to blow off the dust!

  • If you have the A1304 version of MacBook Air, the fan is a separate component. The following steps therefore do not apply to your model. Simply detach the microphone cable from where it is adhered to the fan, and lift the fan out from the machine at this point.

  • Remove the four 2.5 mm Phillips screws securing the fan to the heat sink assembly.

  • Lift the heat sink assembly up off the fan.

  • Lift the cosmetic fan bracket out of the fan.

  • Fan remains.

This guide does not say anything about thermal paste. For the original Mac Book Air model, that requires the fan to be replaced together with the heatsink, the thermal paste should probably be removed and re-applied. Here's a guide on how to do it.

Can i replace the fan from a 2008 A1237 model with the one from the 2008-2009 A1304?
