Smart Way Controlling of all Fans & Airflow. The Rheosmart 3 Fan Controller is designed to make any existing 3-pin fan automatically regularized by the PWM signal from the Motherboard! With three independent channels at a maximum of 30W/channel, a wide selection of fans can be supported.
The Rheosmart 3 Fan Controller operates in two different modes; when connected to a PWM-enabled motherboard, you can allow the system to auto-adjust fan speed through the motherboard's temperature sensor. When switched onto manual mode by pressing the small button below each knob, you turn that specific channel into manual control mode.
