there is a fan controller and a sync controller.......2 separate controllers. the fan controller comes with riing fans that uses a usb interface cable.....the sync controller does not come with the usb interface cable. the fan controller with usb interface utilizes the riing software. the sync controller utilizes the rgb header on the motherboard to control the color patterns through the motherboard manufacturers software. 2 separate things. i hope this helps.
