If there's only one header for case fans, you can either use a 3 way splitter (3 fans should be fine off one mobo header) or you can opt to use a molex to fan splitter and power them directly from the psu. Of course you can also use in line voltage reducers to mod the voltage to 7v for slower speed or use some sort of fan controller. It didn't really show in the video how he did it, but those are the most common ways.
