MacBook Pro Fan making loud noises (like a coffee grinder)
20 - 30 minutos
My right fan started making ridiculously loud noises, it would even wake me from sleep when I left it on overnight.
Super easy, first time I've ever worked on a laptop (usually just replace desktop parts). Took about 30 minutes of time total from taking it apart to getting it up and running again.
Make sure to remember to buy a Torx screwdriver. I had a set of Torx and didn't check the size, ended up way smaller than what I had. Quick trip to Fry's fixed the problem but would have been better if I ordered at the same time as the parts.
