Maximum PC

Hey everyone. I have a Precision M2400, and it's been running pretty well for about 18 months, but it's always had a heat problem. I never really noticed it before, but somehow the GPU, a Quadro 370 (m, of course) is overheating. This isn't just dust or poor transfer, though. I just cleared out the fans, cleaned the heatsinks, replaced the terrible thermal pad with Ceramique, and it still overheats. It's not due to poor conduction, either, as the entire six-inch copper sink will heat up. Even underclocked from 580Mhz to 145 Mhz, it still gets up to 70 degrees by simply playing a movie on Netflix in fullscreen.
So, since the GPU is kind of hot, I was wondering if there was a nice way to give the current cooling system a kick in the pants. If it were my desktop, I'd just add a big-ass fan, but I'm not too familiar with laptops. Am I able to buy a new, super-powered fan that can replace the current one, as well as a better heatsink, or am I just SOL and have to buy a cooling pad?

My 720qm with 5970m gets to 84*c and I gamed on it for over a full year while I was overseas without issue. I read that laptops are designed to run hotter than normal PC's. So I just stopped worrying and keep an eye on the temps from time to time. But adding a cooler pad that blows air up into the laptop cooled it off 5*c. So I say you're SOL, lol, and buy a cooling pad that blows into the laptop unlike most which actually starve it and pull air away from the under side.

It's not the temperature that bothers me so much, since it won't go about 72 or so, even under 100% load, it's just that damned fan makes enough noise to make it impossible to hear anything else.
