The Cooler Master NotePal U2 Plus features two 80mm fans that can be moved around to focus on a laptop's hot spots. The NotePal U2 Plus uses a solid sandblasted aluminum base to help spread the heat from laptop components. Cooler Master set up the U2 Plus notebook cooler to be a multi-functional peripheral. It can be used as protection for a laptop while transporting, using the included strap, along with the additional cooling. Each of the 80mm fans pushes a steady 31 CFM of air and run at a quiet 21 dBA. The fans are powered by a single USB port and the connector includes a pass through, so you can still use the USB port.
