Why use a T8 Torx when these screws are metric hex 2? The T8 didn't work at all. Other than that this was a very easy repair. It cost $29 instead of the $150 that I paid the last time a Mac shop made the same repair.
How can you tell if your fan is bad? I'm replacing the hard drive and I figured I would change the fan too. It doesn't make any noise so I can never tell if it is working. Thanks
