I am having two issues I would really like some input on.. First, my Asus AIO on my GPU gets its RGB signal via 9 pin internal USB off my motherboard. Dragon center does not have an option to address RGB ar this header.. I tried to use armory crate to address this RGB, but it conflicts with Dragon Center and makes my RAM strobe white and sometimes shut off. I tried setting armory crate to address the AIO only but still have the same issue. Is there any way I can get this AIO to stop showing me rainbows and just remain one color of my choosing?

 

Secondly, I am rebuilding my PC in a Fractal Meshify C. I am planning to use the Lian Li unifans. 2 front 140mm intake, 2 top 120mm cpu radiator exhaust fans, and 1 rear 120mm GPU radiator exhaust fan. The lian li controller also connects via internal USB2. If I don't have a free header on my motherboard, can I use a splitter and run both my GPU AIO and the Lian Li controller off the same header? 

 

Wish I either purchased an ASUS mobo or a different AIO. Had no idea this would be an issue at the time.
