The Targus HD3 Gaming Chill Mat is specifically designed to cool high-performance laptops up to 18?. This cooling system features three ultra-quiet, highly efficient fans with bearings that have twice the rated lifespan compared to 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 improves heat dissipation while the laptop is in use. Advanced airflow straighteners help focus the air right where you need it most while reducing air turbulence for more targeted and efficient cooling. The non-skid elastomer feet provide a stable grip so the chill mat does not slide while the laptop is in use. A convenient LED indicator light is positioned on the front of the device so you always know when it?s powered.
