I have a unibody macbook pro 13 (2.53 duo) that I got last year and recently the fan has gotten extremely loud even when there is no cpu usage. I was thinking I was still within my 1 year warranty, but that happened to end on Sept 17. I thought I purchased it in October and was starting to think about getting AppleCare before my year ran out, but I'm too late. I'm not really sure what to do. I've taken the back cover off to look to see if there is something stuck and causing the loud noise, but it appears fine. I figured I could replace the fan myself, but one of the fan screws looks like it might be stripped and I didn't want to mess with it. Does anybody know how much Apple would charge to change/fix it out of warranty? It is extremely loud and annoying. It almost sounds like it's about to die and occasionally will stop spinning altogether, even when the CPU temp is pushing 80C. I guess one bit of good news is that I did purchase it with my AMEX card, so perhaps I should call them to see about repair. Has anybody needed to replace a fan on their macbook pro before or have any advice to share? Thanks!
