Remove heat right at the source. Optimized for components on open shelving, this quiet cooler turns on automatically when satellite/cable boxes, receivers and other heater generating components get too hot. Place the component cooler directly on top of equipment vents. The component cooler is available for systems that require multiple components to be cooled. The low-profile unit produces minimal noise and fits beneath most equipment. Rubber discs are included to raise the height of stacked equipment if necessary.
