Hi Carney
Did you ever resolve this?
I have an X470 Ultra Gaming and 4 x Coolermaster Masterfan Pro 140 RGB.
They work great connected to the case and its adjustable speed, but totally stumped on RGB Fusion connection..
Did you end up getting a controller and did it work?
Cheers

2 x 140mm front intakes Coolermaster Masterfan Pro 140 RGB
Coolermaster RGB Splitter connected to 5 pin 12v GRBW on motherboard and the 2 x RGB fans.

Works with RGB Fusion now (apart from the purple colour!! it's not the right colour).
Replaced the other 2 fans (1 x exhaust and 1 x top) with silentwings 3.
CPU now runs at 55 deg when playing BF V and Far Cry 5 on ultra settings.
Vega 64 runs at around 60-70 deg
Thanks
