In that case:

You'll have 2 'entry' points (let's call them A & B) and C+X exit points -> where C = 1 and X is the amount of fans you want to run. Split each pin parallel.

Entry point A:
Ground and 12V from molex/sata for power (pin 3 & 4)

Entry point B:
PWM & RPM signal from the motherboard header (pin 1 & 2)

Exit point C: this is your "primary fan" it uses all pins (1-2-3-4) and it tells the motherboard the RPM it's running at
Exit points X: this are your other 'split' fans - they only use pin 1, 3 and 4 (NO RPM signal!)

Diagram: (not mine)
Just extend it by connecting every extra fan the same way as fan 2.



That said, I HIGHLY recommend using those 8-fan splitters from Swiftech. If you want, you can just hook up 3 of them (either serial or parallel- using the same method you'd use connecting an other fan)

Curious. I'm going to use Phobya PWM fan hubs (a 4 fan splitter and an 8 fan splitter) to reduce the cable mess without voiding the warranty on the fans by modifying their cables.
