I have the amd 3700x (with default cooler) the cooler has 3 cables, 1 fan connector, 1 rgb connector, and a usb 2.0 header connector. is the usb header connection optional if my motherboard has rgb? i currently have the usb 2.0 header unplugged (i only have 1 and need to plug in something else for it to work) but everything seams to still be okay?!?
