Well to be accurate one is totally dead the other one is wheezing its last. I bought 2 fans online only to take them to the Genius Bar and find out they won't install fan that aren't from them. I called around to a bunch of computer stores in my area and none of them have any experience with Mac's or if they did they wanted to charge an arm and a leg. In most cases like 3 times what I paid for the fans. One guy at Best Buy/Geek Squad said he'd do it for 50 bucks a fan. But when I went back a different staff member said not only does no one there know how to do it but I was grossly under-quoted. *Sigh* So I returned the fans, got my money back and it looks like its back to the genius bar. I've seen people install the fans on Youtube, but with one of them being that close to the logic board I'd sooner tamper with my own DNA than attempt this myself. So, my question is how much can I expect to pay for this? Two fans replaced and installed. Thanks in advance.
