You should stress-test the laptop and see if things are really malfunctioning... try using the everest app for that. There is a section where it will run a series of stress tests, nothing that displays images but it stresses the cpu and gpu mathematically. A good laptop should pass the tests without a problem, otherwise something could be screwy. Run it for 5, 10, or 15 mins if you dare.
I ran mine for almost 10 and the cpu fan was on in all 4 stages (the last stage was loud like a hair dryer) and the cpu reached like 80 degrees.
I have the same setup as you except the vid. card. But pay attention to the screen in case it reaches the real extremes like 100 degrees (but like 80 wasn't extreme enough teehee)...
Also after you are done turn on the on-screen temp. controls and run them when you play fear, etc. for a little while. Post the temps, the cpu shouldn't reach THAT far just by playing a game like that (esp. since the C2D are pretty efficient). You don't technically need a inter cooler attachment like that since laptops should be designed to run a little hot (understandably more hot that desktops but they do a series of tests on each configuration when designing it so it shouldn't really die just by playing games unless it has major malfunctions). But when it comes to summers, I would definitely run mine in ac rooms when playing games.
