In the world of computers, heat tends to be a bad thing. Heat is a major limiting factor in the performance of most computers, especially laptops, which do not have room for large fans or other cooling systems due to their compact size. This is where an external notebook cooler, like this one from Antec, comes in handy. The design of this cooler allows a constant airflow underneath the laptop, bringing in cool air and removing the hot air. This constant circulation of air, in theory, helps the performance of the laptop. Anyone who has used their laptop on their legs will also appreciate not having the hot bottom of the laptop resting directly on their thighs.
