The Notebook Cooler Classic runs off any USB port and provides quiet cooling to protect your investment and to reduce heat-related instability. An aluminum surface conducts heat away from the laptop. Heat is dissipated through rear and side vents, and your computer, desk and lap stay cool. The Notebook Cooler Classic is compatible with all notebooks with screens up to 16.0".
