The Zalman ZM-MFC1 is an interesting fan controller because it is both a fan controller and a mini rheobus. It has six channels, we’ll call them channels A, B, C, D, E, and F. channels A, B, C, and D are controlled by adjustable knobs on the left of the controller and channels E and F are controlled by 2 switches. These switches have Three different settings: 12v, 5v, and off. Having the ability to completely turn off certain fans is quite nice in certain situations.
