The advantages of the PWM control technique are undisputed. Good and cheap PWM-enabled fans are on the market. However, PC motherboards make insufficient use of the PWM technology. There are also hardly any PWM fan controllers for retrofitting available – especially with so many fan
The program provides a graphical interface to configure the controller and to display the readings. The fans and the temperature sensors can be identified and activated when required. In the basic functionality, the speed of the fans can be individually adjusted with the sliders. The
First and foremost, the firmware generates the PWM signal to the 8 outputs of a port. The control values are provided over the serial interface. In parallel, the firmware digitizes analog values periodically and sends them on to the PC. The tacho signal is also
