Now it's time to test the unit. Hook it up to your computer power supply and connect all your fans to the 4 Fanbus wire clip terminals. Turn on your systems and start to flick the switch one at a time.

In the previous guide, you see that 5V isn't enough to make my 120mm fan start rotating. This time however, the same fan started without a glitch! And I can feel that it is actually moving a lot more air than at 5V! But at the same noise level!

12V was obviously not a problem. :O) And none of the fans stalled when switched back to 7V.

I am pretty pleased that my first attempt at the 7V/Off/12V Baybus was a successful one. The unit ended up in my buddy Yuzfigo's system.
