I handle screws much like Adam, but I print out the iFixit guide and tape the screws to the guide using blue painters tape.

Thanks for the great instructions on replacing the left fan. Everything worked to perfection and I even put my MacBook Pro back together again without any trouble or missing parts. :) The excessive heat on the machine is gone and I am smiling again.

Also, excellent service on the order and delivery time which was much appreciated.

Cheers, Lowell

Very useful instructions.

I had a very noisy fan and so pulled my macbook apart and cleaned dust out. However, when I put back together, the fan didn’t work at all!!

Started looking at buying a replacement, then had an idea. Took it apart again, and this time I put a small amount of HAIR CLIPPER OIL on the fan’s axel!!

Put it all back together and now have a perfectly functioning, quiet fan again!

These Fans Are Horrible! I’ve become an expert at getting my Mac laptop open because of these horrible fans. I’ve replaced them both three times because they whine and squeal. This is a great guide for you to do the same.
