Check out the second link in my post above. It gives instructions and details.

You only need to save the yellow wire on one of the fans you are connecting, and only then if you want to hook it up to an RPM monitor. Easiest thing to do is hook it up to a fan controller, where you adjust the speed manually. Make sure you don't just connect them all together and then plug into one of your motherboard fan leads ... that may cause a problem.

You can mess around with extenders/splitters, but you'll be better off doing it yourself. It's not that hard once you do the first one - it's actually kind of addicting.
