Do your audio/video components live in an enclosed closet or cabinet? If so, the heat they generate while operating could affect their operation or even damage them. A cooling fan is the solution, but how do you know when to turn it on? The answer is the Bora Lite THS. It has a built-in thermal switch that automatically activates the fan when the temperature inside the enclosure reaches 85°. Your gear receives the cooling air circulation it needs, and only when it needs it.
The fan moves 65 cubic feet of air per minute. The frame is specially designed to isolate any vibration from the fan, so there's no sympathetic hum from your cabinet. And the fan itself is amazingly quiet, emitting a mere 11dB soft as the rustle of leaves.
