An intelligent cooling fan system designed to be mounted onto a wide range of 19-inch racks requiring quiet or high airflow cooling. Maintaining an optimal temperature for rack-mount equipment prevents overheating, ensures constant performance, and extends their lifespan. The LCD digital controller features a programmable thermostat with automated speed control, alarm warnings, status alerts, and backup memory. The system is housed in a solid aluminum construction that takes up one rack units of space (1U). Each aluminum frame is anodized with a light-brush finish, then the corners CNC-machined and edges chamfered for a high-end professional appearance. This model holds six custom-engineered dual-ball bearing fans rated at 67,000 hours, and certified by CE and RoHS. The fans are set to exhaust out heated air and should be positioned near the top of the rack; an intake version of this model is available, sold separately. This complete kit includes the 1U fan unit, corded 6-ft thermal probe, user’s manual, rack mount screws, cage nuts, and corded 6-ft power supply.
