Ordered my fan yesterday it arrived today. Followed these steps it was so easy. My computer has been thru !@#$ and back a few times it's an early model 2009 MacBook and the fan started to sound like that jet so many have referred to would overheat and shutdown. I've never attempted to fix a computer so was a bit nervous but it was a fun project. Can't imagine how much I saved if I were to take it into a repair shop. Thanks for being so fast with delivery and the instructions! See if we can get a bit more life out of the Ol girl!!
