The fan/rgb controller uses a 12v connector to the motherboard. In other words, NOT ARGB. Also, the fans have two speeds (again, from the controller) - Low and High. There is no ability to use motherboard PWM control for them.
Coming into this belatedly, but I used this case for my son's PC, father/son build for Christmas 2019.
The US version does not allow for the two fan speeds. That said, what little noise you hear from the fans is a sort of comforting whoosh, not really intrusive except in a quiet office setting maybe.
I'd have to double-check the connections, but, while there are pre-set RGB patterns for the fan, one is to use what the board does. There is a connection to the board, and we were able to set it up to use what the ARGB software assigns to it.
