In use, the NZXT Sentry Mix 2 is very simple and easy to set. Each potentiometer controls one channel from 40% to 100% of the full power. There is no way to turn off a fan.
There is also mode to sense fan speed, which means the controller will not show if the fan is really spinning or if it has stopped for some reason. Actually, it doesn’t even show if there is a fan connected to each channel.
On the other hand, the channel number below each potentiometer is illuminated and, pressing the button at the left of the controller, you can change the color. You can set it to red, blue, green, orange, or white. Pressing the button for five seconds will turn off the light (while continuing to control the fans).
