No fan or controller needs an RPM sensor wire to work. You hook the black wire to ground, and the red wire to 5-12v and the fan just works. The rpm sensor and sensor wire has nothing to do w/ this closed circuit.
You can test this very simply. Get a cheap fan from the closet or old PC that has an rpm wire. Hook it up to your controller and make sure it works right. Now, cut the yellow wire, and see if it still works correctly. I guarantee you that it will. The only thing different is now you cannot get the rpm readout.
It certainly does if you want the RPM display on the Fan Controller to show the RPM of the fans that you're monitoring. Which has been my point all along. If you still can't figure out what I'm getting at I'll try to explain it again.
I want to see what rpm's the fans are turning at by using the displays of my fan controllers.
Of course fans will work that don't have rpm sensors, but, they will not report the rpm's that they are turning. Can you now comprehend what I'm saying? I really can't simplify my explanation any further.
