So.im using the corsair XD3 pump combo for my but I dont have the commander Pro or the rgb thing for it. So I'm curious what are the 2 cables that are for rgb? I know I can use just the motherboard and molex to power and rgb but there are 2 rgb connectors coming out of the XD3. There is an adaptor but like I keep saying it only connects to one rgb cable and the other one is just dangling free. What do I do with it?
