Overview

The Cooler Master NotePal (R9-NBC-ADAS) is a laptop cooling pad built around an all-aluminum surface that serves a dual purpose: it provides a rigid, stable platform for your notebook while acting as a passive heat sink that draws warmth away from the laptop's underside. Beneath the aluminum deck sit two 70 x 70 x 15 mm fans spinning at 1,500 RPM, pushing 10.5 CFM of air upward through the laptop's intake vents. At just 21 dBA, the fans are effectively silent — well below the ambient noise level of a typical office — making the NotePal a good fit for quiet work environments, libraries, and conference calls.

The cooler measures 320 x 300 x 42 mm, sized to support most 15-inch notebooks including widescreen models. It draws power directly from a laptop USB port, eliminating the need for a separate power supply. Two USB 2.0 passthrough ports are built in, so connecting the cooler does not reduce your available port count. The sleeve bearing fans offer reliable operation for general-use scenarios, though users who run their cooler continuously for years may eventually notice bearing wear. Overall, the NotePal is designed for everyday productivity users who want a simple, quiet way to keep their laptop temperatures in check without adding bulk or complexity to their setup.
