There should be two cables going out of the Wraith. 1x for the fan header and 1x for RGB.
On the bottom of the black shroud you have two small sockets, one that will connect to a RGB 12v header (this way you won't control the ring) and one that will connect to a USB header. Pick and Plug (PnP ) only ONE!
Now you will have two cables going out of the cooler.
