The Targus HD3 Gaming Chill Mat is specifically designed to cool up to 18" high-performance laptops. This cooling system features three ultra-quiet highly efficient fans with bearings that have twice the rated lifespan than standard cooling device fans. An adjustable fan speed dial features precise tactile control so it's easy to adjust the cooling level without taking your eyes off of the laptop screen. The durable aluminum alloy grill is lightweight and cool to the touch. Its industrial perforated design was built to improve heat dissipation while the laptop is in use.
