Cooler pad
A hardware accessory that is placed beneath a laptop to help reduce the laptops overall heat by dissipating the heat using fans in the cooler pad. In addition to helping keep a laptop cooler,
cooler pads can also help with keeping your lap cool if working on a laptop while it's on your legs.
In the picture to the right, is a picture of the Belkin laptop cooling pad, which connects to your USB port to power a small fan that helps keep a good airflow beneath the laptop.
