MacBook Pro Fan making loud noises (like a coffee grinder)

Mi Problema

My right fan started making ridiculously loud noises, it would even wake me from sleep when I left it on overnight.

Mi Solución

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.

Mi Consejo

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.
