The Active Thermal Management System 2, a self-contained ventilating system for small-to-midsize enclosures with moderate heat loads, has been redesigned. It consists of two 120mm fans on a mounting board which also holds a thermal control board with a remote sensor. A small display on the control board is meant for set-up only. It reads in degrees Celsius, not Fahrenheit.
The System 2 is mounted over a 14 1/2" x 5 1/2" rectangular hole (not exact - verify this dimension with the System 2 to be installed) located at the hottest part of the enclosure, usually at the top rear, and moves this air out into the room.The foam strips around the base of the System 2 will provide an air-tight seal.
