Thermoswitch-controlled quiet cooling fans, with enlarged air-chamber bases & multi-speed controlThese two super-quiet 80mm fan units are designed sit on your component\'s top air vents, while being turn on and off by a thermoswitch controller. Each fan has a special raised air-chamber base, which covers nearly twice the area of a standard fan. In addition, you control the speed of the fans, with the multi-voltage power transformer. The thermoswitch module turns the fans on at approximately 82 degrees Fahrenheit (a good operating temperature for most equipment). Just place the thermoswitch heat collector over a warm spot on top of your component\'s air vents, and it will do the rest. A vortex of air is pulled out of the top of your component over the full area of the fan\'s raised bases. The system is intended for receivers, amplifiers and other components with top air vents.

Note: In the listing pictures, the component cooling systems are shown in two views: 1) On top of a receiver or other component to show how it is used and 2) against a colored panel, displaying the complete system. These components and panels are used for display purposes only, and are not included with the system.
