The case has a cable, or two cables connected together, from the two large front fans. I plugged it into the fan header on the mobo, but there is a white connector attached to this cable which seems to fit nowhere on the mobo. Is it for the rgb? Does it serve any necessary function? Can I ignore it since I’m not using rgb anyway? It’s the only white connector on this case, so I’m hoping that other owners of the case can please explain its purpose.
