The fan controller has 2 RGB modes: chassis button control and motherboard control. In order to switch to motherboard control, you must press the chassis button for 3-5 seconds until the fans flash.
No, not yet.
I have recently bought the V200 TG RGB case which comes with 3 RGB and 1 non-RGB 120mm fans, and I would like to be able to control the fans speed. The included controller has no way of doing this, but my motherboard has spare fan connectors, and I wanted to know if there was any way I could control the fan speed with my motherboard. I have a MSI B450 Gaming Plus MB.
