Hi all, Last night I noticed my MBP fans (I think) started making a low "whirring" noise, as if the fans were about to die. When I angled the MBP, the noise got worse. It was going about 2000 rpm, which is usually virtually silent. This was right after I played an intensive game of Company of Heroes where the fans were almost maxed out. I put it to sleep and this morning the whirring is gone. Should I be worried (i.e. call AppleCare)? I did a search for this problem and it doesn't seem to be a common one... Thanks for any advice!
