Just R&R'ed the fan in my black MacBook Core 2 Duo tonight. Took me 30 minutes tops and I was taking my time. These instructions are SPOT ON! Great job ifixit.com! Two thumbs up!
Follow the instructions exactly as you see and have a piece of paper taped to the table next to you that you can outline all the screws you took out so you know where they go back in. I expected this to be a LOT harder, but it was one of the simplest repairs I've ever done to ANY computer!
