If hot laptops have ever been a problem, here's the perfect, simple solution. Cooler Master NotePal all-aluminum coolers work for 15-and 17-inch laptops and even have a range designed for Apple's widescreens. The NotePal takes down heat with twin 2.8-inch fans (that have a life expectancy of 3000 hours), which also help with airflow around your laptop, shielding it from any direct heat. And bonus—it's fairly quiet as well. The NotePal is powered directly from your laptop and has two 2.0 USB ports and an on/off power button for the fans. The line starts at about $40.
