Already at first glance, the Enermax UC-A8FATR4 sets itself apart from the competition, as its left and right dial controls glow in different colors. At first we thought that it was intended that way just to look cool. As we began to understand the functions though, the color coding made sense. The left dial and the blue-lighting in the display pertain to one of two separate fan controllers. Green is for the other one. When you throw a switch the display turns green to show the temperature and fan data for the second controller.

The UC-A8FATR4 will first detect whether a rotating fan is attached to one of the four possible connections before displaying the rotations. If the fan is stopped or is rotating below 1000 rpm, it starts to beep. The signal only goes away after restarting the fan or resetting the controllers. A small sliding control in the faceplate switches the display between Celsius and Fahrenheit.

The fan controller is actually made up of two separate units.

Listen to the alarm sound

Is that an alarm clock? Time to get up again already?

The dual button is used to switch over to the other controller.

Both controller units share the same display.

One unit glows green, the other blue.

The connection cables almost all attach firmly onto the fan controller.
