I bought a new ASUS motherboard. I have three fan connection plug in's. The CPU
is ok and the chassis fan one is ok, but what about the power fan connector. All
it does I BELIEVE is measure the speed of the Power Supply Fan.
I have a device I found is my miscellanous collection that on one end is a 3 prong
plug in with a black and red wire going to it, with one not connected. The black
and red wire go back to a 4 prong power connector . The red goes to a yellow wire(I
believe is 12V) and the black to black(I believe is ground). Is this the correct
connector to use just to measure fan speed or is it even necessary?
