In general, laptops get very hot. You won't find a laptop that stays much cooler than the rest. One reason they get so hot is that all of the internal hardware is in a tight fit (that's what makes it mobile and portable).
There are some websites that sell laptop coolers. Try http://www.xoxide.com or go to Google or Yahoo! and search "Laptop Coolers."
there are bay freezers for laptops that might do the trick, though celerons tend to run hot, but if playin those kinda games y not a pc?? better venting and better proformce, and more bang for the buck compared to laptops
