The mobo ARGB control system has no way to send out different control signals to multiple devices on one mobo output header. This means that all three fan light sustems are receiving exactly the SAME control signals from the mobo and do the same thing. I fully expect that the ARGB cables from each fan are all connected together in an ARGB Splitter, and that then is plugged into the mobo 3-pin ARGB header. Of course, you would be using two separate software utilities to do this - neither of them can access the other system. They would produce different displays - in fact, because you would be using two completely independent controllers, you could not make them match each other. Then you would use the utility that came with your mobo, RGB Fusion 2, to control that second group. The other group of lighting cables can be connected instead to the mobo ARGB header.

One will continue to be connected to the Cooler Master controller and all of them will do their joint thing. So you do have two independent controllers with separate outputs, and you could arrange your fans' lighting in two groups.

Your mobo does have one ARGB header that you are not using. You are using ONE ARGB controller to connect all of your lighted fans, so they all do the same thing because they all get exactly the same signals. The key to your situation is a simple word, 'the', as in: 'I connected the controller to. You do NOT try to connect an ARGB light device to more than one controller.
