I have a asus prime B450-Plus and I am trying to use phanteks SK PWM fans, the fans are spining fine but the rgb does not work. The rgb header on the motherboard had has a 4 pin connector but the fans did not come with a cable to connect to that header so I bought one that phanteks was selling. The problem is that the cable I got has 4 pin connectors but the fans only has 3 pin and I do not know what to do. Can anyone help?
