My aging mac book pro began making loud fan noise whenever I watch Hi-def videos on youtube ( or on any other flash based video sites ). The fan noise got so loud, that I almost thought it was about to explode.
The repair guide from iFixIt was clear and easy to follow. I was able to disassemble my macbook pro, and re-assemble it back to life. My macbook is quite as brand new one. thanks iFixIt!
iFixIt gave me two choices for screwdrivers ( one with life-time warranty and another with limited warranty ). I purchased ones with limited warranty and they are solid and pretty much impossible to break. Unless you are fixing a bunch of mac books, buy screwdrivers with limited warranty and save few bucks.
