Laptop Problem - Alienware I think its overheating

[Bigka79]

I currently play a lot of poker on my alienware laptop. the main problem is about 2 hours into a session with 4 tables open at a time (poker ace and pokertracker running smoothly) my computer will just shut down.

i was wondering if anyone had any advice for this. i think it is due to heating problems as it only happens during the summer and quickly on hot days. i was wondering if i could find a way to drop the temp. on this computer maybe through a 3rd party fan or something of that nature

thanks
