The Laptop Cooling & Comfort Stand from Xbrand uses USB-powered cooling fans to maintain system longevity and optimum performance by protecting your computer (and you) from the damaging effects of excessive heat. It can also improve workplace comfort by placing a gentle slope on your laptop's keyboard and raising your screen height to reduce neck and wrist strain commonly associated with laptop computer use. Blowing ambient air on the laptop enhances cooling by pushing hot air in its natural upward direction while the curved platform increases laptop clearance to naturally enhance the fan's cooling capacity. The fan is 2.75" with 11 cooling blades. Warranty: 1 year. |
