Cool-it II is single unit equipment cooler that is placed on top of equipment that is running hotter than it should be. Two almost totally silent 4.7-inch (120mm) fans send stream of air down into the equipment to remove excess heat and prevent damage due to overheating. Needing virtually no installation, cool-it II is simply placed on top of the overheated receiver, processor or amplifier, the thermal switch is fastened and the wall-type power supply is plugged into an always-live outlet. When the thermal switch closes cool-it II sends quiet stream of cool air down into the component. Using the Cool-it II dramatically lowers the temperature of the output transistors and nearby components within a receiver or amplifier and will extend its useful life significantly.
