Powered by a single USB connection to your laptop, the Chill Mat has two fairly quiet fans that aim toward the back-left and back-right corners of the laptop. To improve airflow, the Chill Mat itself has an open design, with a large air channel in the middle, allowing for easy air intake.
The only problem we ran into was with the four rubber stoppers that sit on the plastic fan grate. Each is held in place by four tiny rubber nubs that plug into the circular holes in the fan grate, but they pulled up far too easily when moving our laptop around, and required some serious elbow grease to push back into place.
