Hi All, I recently bought a Thermaltake V250 which comes with 3 Thermaltale ARGB fans and a fan controller on the back of the motherboard tray. I also recently bought a a Gigabyte B450 Elite motherboard. However I am a bit confused, both the case and the motherboard claim to support RGB Fusion. However I can't work out how I am supposed connect my fan controller and motherboard as they seem to have different connectors. Any help is greatly appreciated. Thanks
