Hi, I mean the sensor to change the color fans. I don't know where it's going to work, what part of the case. The K20 comes with a sensor that goes inside the case and with a remote control that is to change the LED lights color. Greetings friend.
Yeah, I don't know anything about that. I am not into case lighting as I personally don't think cases should be distractions or draw attention to themselves (I prefer to pay attention to what's happening on my monitors). I would think it would be in the user guide.
