My wife's MacBook has been overheating for some time, and then shutting itself down. Your instructions were great, but I did note that I needed to unscrew the cable tie near the speaker in Step 17.
The system had some dust in it, used the air can to spray it all out. Dust was on the heatsink vents, too. Closed it all up, and peak temps during a software install that crashed it three times yesterday was 145F - yesterday it was passing 170F and crashing.
Thanks for the instructions, ifixit!
Download and print out the PDF version of the repair guide. Tape the screws to their corresponding image in the guide so that you can't go wrong!
what a great idea! i've been thinking about a solution for organizing screws. that's genius!

Good Idea. I generally sketch up rough diagrams and putsmall pieces of double sided tapes and stick the screws on my drawing.
