You can see this in my latest build log to the 5900X, but I used to use Corsair's product for RGB, mine wasn't the full commander Pro, combined with my ol'faithful Swiftech hub for power and PWM control.
Now I've ditched the Corsair stuff mostly because I actually had a hardware issue with mine, fans wouldn't light, etc. but also because I was repeatedly frustrated with iCue and the inconsistent setting of RGB profiles. So the new build gets rid of RGB lighting completely in the fans, and my new ram has no RGB anyway. So now just RGB on the motherboard and GPU. It also reduces the programs running on start up and in the background, which is never a bad thing.
I like the hub because it simplifies the wiring and cable management, bringing everything back behind the the motherboard and just a single connector out to a motherboard fan header. I don't find I need individual fan curves for my five case fans, so this works fine for me and keeps things tidy.
