I’ve been having my Thermaltake Riing 12 RGB (CL-F042-PL12SW-B) for about a month now and suddenly this happened.

Only one fan lights up but the other two doesn’t. Sometimes when I turn on my PC, the other two lights up and turns off. Most of the time, they don’t light up at all when I press the power button. All of them are connected to a fan controller included.
