OK, so I got a memory card reader which has fan controllers on it.
You supply the reader with power and then it had 2 wires coming off it for the two fan controllers.
The wires are like this:
Black + yellow wire > 3 pin female connector (with red, yellow and black wires) > 3 pin male connector.
So, I plugged in the 3 pin fan into the end male connector and the other into the motherboard (like the instructions said). No luck. Then I tried the middle one straight into the power and it didn't work either.
Thanks for your time.
