i think its just a laptop thing to over heat (mostly, i know other things can come into play) but, like the other guy said, some kind of stand helps. i have a flat basket that i can flip over and still rest on my lap, the computer goes on top, and it can breath way better. also, if you have a box fan or are running the AC set the computer next to it. i have a box fan set up and just blast my computer with it (trying to hit the processor and hard disk area the most) or if your not getto like me, they actually make platform/fan cooling systems for laptops that plug into the USB for power. and i don't know how comfortable you are with taking your computer apart (laptops are known to be head aches in this respect) but i took out the CPU fan and cleaned it and its cover and the heat sink...and did a general dust cleaning. dust is like an insulator. and plus when it is blocking the CPU fan that doesn't help ether. anyway after i cleaned that up, i noticed a difference in heat management and performance (grant it the performance boost was minimal it was there all the same)
