I got the unibody macbook the day after it came out. (the 2.0 ghz model) The fans were dead silent when I first got it unless they were really going then you could hear them. Now they always make a purring sound and at times will go into a crazy noise and it only gets worse until I shut down because I don't let it last too long because it is a horrid sound and I don't want anything getting damaged. It's coming from the left fan. I then installed fan control just to see what it was saying about my fans, I start it up and then I see this. The right fan is going at -1 rpm? So I have no idea whats going on with that. Even just this morning right after it booted up, I had nothing running but I started up photobooth because I heard the fans getting louder and it ended in this... http://b3.s3.p.quickshareit.com/files/movie25371b88.mov So will apple fix this? I've seen people have fan problems and say apple wouldnt fix it because they couldnt recreate the problem at the store? So what if the sound is too faint in the store and it ends up not making the loud sounds? The loud sounds are very random, just like in that video, it was taken first thing in the morning after booting up.
