The Sentry Mix 2
The fan controller uses only one 5.25” bay. It is merely a fan controller, with neither thermometers nor USB ports. Each channel has a simple sliding potentiometer and an LED illuminated number below it. There is a small button on the left of the front panel, which will be discussed later. The front panel is made of plastic.
Figure 4 exhibits the side of the controller, where you see the holes for the screws.
Figure 5 presents the rear side of the controller. The cables come connected to the printed circuit board, but you can remove the ones you will not use.
