PWM Fan Controller

Control and monitor up to 8 3- and 4-pin PC fans

PWM Fan Controller

Our first project, the smart PWM fan controller allows you to control and monitor up to 8 standard 3- or 4- pin PWM fans. With RPM monitoring for 4-pin fans and PWM control of the entire bank, you can adjust and monitor the speed of the fans, along with overall power control via a relay. Everything is powered by a 12-volt barrel jack or 4-pin Molex EPS input for maximum flexibility.
