So i picked up my 1st mac in November, primary for school (and WoW). It ran perfectly with only minor problems with getting used to OS X, but lately it have started to turn really, really hot when playing WoW (all graphix on low!!) and Counter-Strike with CrossOver. Even when i browse the web i now hear the fan a bit, where it ran completely silent. I googled a bit, and found out that there sometimes is a piece of plastic in the vent, to prevent dust at the factories, but that's not the case. It is the 2,4 unibody model if it makes a diffrence. And i admit that it have been lying on my bed, playing movies alot when i couldn't fall asleep. So my questions are: Have anyone else experienced this, and/or is it normal? Can it be fixed? Should i call AppleCare?
