    • 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 faces of the CPU and GPU.

    • 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.

    • Logic board remains.

    • When reassembling your logic board, be sure the rubber gasket is installed correctly. The nub on the gasket should mate with the hole cut into the logic board near the heat sink fins.

    • The rubber gasket should attach to the end of the heat sink as seen in the second picture.

This does not show the battery removal in the early steps, but it is shown as removed in later steps.

Thanks for pointing that out! Missing steps have been added :)

Thanks i fixed my MacBook Air (11 inch) with this tutorial.

My MBA became very slow after a water spill over the keyboard.

Although Hardware check said everything was fine, i disabled the MB and found a spot with corrosion, after removing the corrosion and assembling it was on speed again. the water spill was some months ago so it had some time to corrode and show were a clean was needed :-)

Wat I real appreciatie is the accurate way of description of the connector disassembly :-)

Would it be possible to upgrade this machine to hold a newer logic board?

Get That Geek - Réponse

No. There are no compatible logic boards that I am aware of.
