I have a mid-2009 Macbook Pro and unfortunately it is my only computer so I do all of my gaming on it (I have Boot Camp). The problem is whenever I play any game (whether on Mac OS or on Windows), there's a chance that after a few minutes my FPS will suddenly drop to around 2. It doesn't matter what game it is, whether it's Crysis or Warcraft 3 it happens eventually. After trying to solve this for a couple of years (by reintalling OS, switching from XP to 7, etc) I've reached the conclusion that the only reasonable explanation for this is that there's dust in my fans and my GPU starts overheating whenever I play a game. So my question is, how do I clean my Macbook's fans? Also I'm not really good with this kind of stuff, so is there anyone who would do this for me? (Can I take my Macbook to an Apple store and ask them to clean it?) Thanks.
