I use an ANTEC two fan "coolpad". I won't rave about it's performance, but I can say that it has provided more airflow, more quietly, than I got without it. What's important is examining the laptop to figure out what the airflow and heat-dispersion "plan" might be.

My laptop "inhales" through the back, and "exhales" through the bottom. The coolpad enhances the pull of air from the exhale-slots, blowing the hot air more forcefully out to the sides than the laptop's fans themselves. Also, I tilt the coolpad (with laptop atop it) about 5 degrees toward me, providing more room to disperse hot air.

My GPU and CPU are in the "top" (as you look at the screen) left and right corners, so I make sure that the fan are positioned nearby.

When I know I want to game for a few hours, I also remove the battery (a slide-out deal, on the lower-right of the lappie) to increase airflow - and if it's a Steam game (like Red orchestra) where I don't need a disc to play, I also remove the DVD player module for the same reason.

This plan works for me, because my laptop is a desktop replacement - it seldom moves from by bedside table. I once took it with me on a trip to New Mexico, figuring I could get a few turns of MTW in when it wasn't my turn to drive. The heat generated just about burnt my pants-covered legs! One hour was all I could stand. So, these hi-end GPU & CPU laptops, so-called 'desktop replacements', are "cool", but not cool. :)

Does anyone know if the dual-core CPU laptops are running any cooler?
