Fans have always been an issue, there's no set standards. Some are molex, some are 5v, 7v, 9v or 12v. Some are 2pin, 3pin or 4pin. I've even seen 12pin hook ups. When RGB first got crazy, after the LED craze, nobody had the same connection or specification. Everybody used what they wanted. Corsair even went as far as using a hair-brained idea and used 4pin PWM connections for its RGB, on a 3pin DC fan. Ppl burned them out quick and several complaints later this was changed again. Most are now leaning towards a 5050 connection for strips, 4pin molex looking plugs (3wires) for ARGB, 4/5 pin for RGB /RGBW, but that still leaves software. Now you have asrock, CoolerMaster, thermaltake, Asus, MSI, Gigabyte, Corsair, and thats just the major players, not mentioning the half a hundred other wannabes throwing their opinions out there. And most are not universal, but will be compatible with a few others.
Which is where you are now. Trying to force compatability between two similar systems that are not fully incorporated the way an ASR board would have been. So it's going to be a Royal pain in the tuskus, aggravating, frustrating, but it has been accomplished, so it is doable. You are going to have to open the CM software with the Asus software at the same time. Turn things on/off, see what's gray'd out. Call Asus tech support, hunt the web for as much info as possible. It's been done, but I haven't yet seen a single post explaining exactly how it was accomplished, in what order, with what connections. No step by step instructions that cover every scenario. Most of what I have seen is that it's been accomplished by ppl with mobo's that have ARGB headers, so even that might preclude success.
It might be you can't get one software to sync and control all, you may just have to use both, Asus for the case lighting, CM for the rad fans. That'd suck, but it is what it is when there's no universal compliance.
