Asus fan control cable

Hi, in this video they talk about a fan cable that goes from the power supply to the 6 fans and motherboard. So it takes power from the power supply and the speed is controlled by the motherboard if I understand it correctly. If so, what is the name of this cable and were can I find it? And will it work for 3 pin fans?
