Hi, I have one Thermaltake TH120 V2 ARGB Sync that works regularly for cooling but the RGB part doesn't work. The fan does not turn on and the pump display is off. I don't understand how to make it work, I followed the instructions in the manual but it doesn't turn on. Is there something that needs to be attached to the motherboard? Is it possible that you need the installed software or some settings in the video to start it?
