Hey folks. So I have a 1.83 version 15" CD MBP. Just recently the left fan by the screen has started to make this loud propeller like sound. When I'm putting the computer under heavy load (Photoshop or a game) it gets really loud like the sound made by a playing card slapping against bicycle spokes (was I the only one who did that as a child?) It's almost grinding and it really is loud to the point where my roommate on the other side of the wall might hear. So what's up with my computer? I'm going to be going to an Apple Store soon (duh) but if there was a home-remedy I'd rather try that first. Thanks so much!
