What makes a fan PWM?

The difference between DC fans and PWM fans is that DC fans have an extra pin for pulse width measurement. The fan’s speed can be controlled by this fourth pin. The fans work by continuously sending power to them.

Can 3 pin fans be PWM?

There is only one mode for putting out signals for a 4-pin fan system headers. The power can be provided to both fan types, but it can’t control the speed of a 3-pin fan, which will run full speed all the time.

How do you connect a 4-pin fan to a 3 pin fan controller?

The 4-pin fans have to have a 4-pin splitter. Two of these can be used to connect to the SYS_FAN1 and SYS_FAN2 headers. Your SYS_FAN1 and 2 headers can be used to control all of them.

How do I control the speed of a 3 wire fan?

The system for controlling the speed of 3-pin fans is called “Voltage Control Mode”, or sometimes “DC Mode”, and it only works if the voltage on Pin #2 is changed. A 4-pin fan has a fixed voltage supply and a special signal on Pin 4 that can be used to control it in a different way.
