AV Cabinet/Desk Cooling Fans with Adjustable Thermostat & multispeed/White Model This cooling system is designed to be mounted in your enclosed equipment cabinet, home theater cabinet or computer desk. It will quietly exhaust the hot air outside, or pull cooling air into the cabinet -- you choose how it is set up. It has 2 high-quality, low-noise 80mm fans mounted together into a single housing. The fan is controlled by a rugged, no-maintenance adjustable thermostat. In addition, YOU select the fan speed, using the multi-speed fan controller. The 80mm dual-fan cabinet cooling unit measures approximately 4-5/8" high x 8" wide, which includes the mounting plate. The required mounting hole is approximately 3-1/4" high x 6-5/8" wide. The unit is 1-1/4" thick behind the mounting plate, and only requires about 1/3" additional space behind the back of the fan to allow for airflow. At full speed, the 80mm dual-fan unit is rated at 22db, while moving 62 cubic feet of air per minute. It has approximately these specs at different speeds: 1/2 speed = 32CFM at 13db, 2/3 speed = 41CFM at 16db , and 3/4 speed = 46CFM at 19db (approximate). With cabinet cooling, slow (and quiet) are the way to go! This model has a white mounting plate and front grill, and stainless silver screws on the front. The back (non-visible) side is black.
