Have you hooked up the fans that came with the case to the Commander? If so that means your lighting node core(the hub that came with the case) won't have anything hooked up to it. If you are adding extra fans to the Commander and have the original fans hooked up to the included hub you want to plug the USB header from the included hub into the Commanders USB port. If this doesn't work plug the included hub directly into your motherboard.
You also need to set the type of fans hooked up to the commander and lighting node. You do this in Lighting Setup on each device.
