I don't quite understand it, there is a 4pin PWM signal, e.g. from the mainboard, but 3pin connections go to the fans? How are the fans controlled? PWM or via the voltage?
it doesn't work either, the fans turn to 100%, so i bought another product.

I can only agree with the previous speaker. I also had the problem and thought it was controlled via the voltage. However, the fans always ran full for me too, so I removed it again and installed a manual fan control.
