Do I see it correctly that you always supply 12V to the fan?

Some Fan understand 0% PWM signal as a stop and others spin at minimal speed.
Without means of interrupting power to the fan it is not possible to guarantee to stop a fan for a silent mode.

Hey Fabian.

OpenFAN controls the fans via PWM signal.

So at 0% PWM the fan will be at whatever state the fan manufacturer designed as minimum speed. Which should be OFF but there are fan manufacturers that deviate from this.
