Due to a misunderstanding about different RGB standards I find myself in a bit of quandary. I have the Level 20 MT with the ARGB fans, but it turns out that my MB (ROG Strix B-450F) only supports four pin 12v RGB, whereas the ARGB requires the 5v 3 pin. I'm seeing noise that the only way I'm ever going to get software control of the fan ARGB is by sourcing a controller that will run through USB header to provide the necessary ports/controls, but most of the controllers I see don't appear to have the USB port (also, given the fan plugs on the case seem to be very specific to the case board, I'm not sure that it would work right without the board? Yes, I am a tad lost here.
