A:Answer This does not require a motherboard ARGB header, this plugs into a USB 2.0 header on the motherboard and uses a molex to barrel plug adapter for power which is included. Depending on the hub your fans use this may or may not work, this is designed to replace most argb hubs with its own software.
it will only control the lights, not the fan speeds. If your fans need a hub to control their speeds, it should accept a signal from this, but this will only power the lights, not the fans themselves
