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

Be sure to apply a new layer of thermal paste before reinstalling your heat sink.

    • 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

you should seriously note the danger of the cpu screw holders. apple for some reason decided to attach the fricken screw receivers/standoffs via surface mount. they dont have a bottom cap either. use a screw slightly too long or turn too far and pop(screw pushes against motherboard and pops the holder off)... one corner is unable to be screwed in. ask me how i learned this...lol...I cant see how this design decision helps anything but apples wallet. the other side of the board has components smds as well so its not like a really short through hole was undo-able.

There is step missing between 3 and 4. There is another ribbon cable over fan that is still there in step 3 but gone in step 4.
