I have an Asus A7N8X Deluxe and a Vantec Aeroflow T.M.D. fan/heatsink. The problem is that the mobo apparently does not provide enough current at start-up to spin the fan, so I had to use a 3/4 pin adapter and plug directly into the power supply. Now I can't monitor the fan speed so I want to connect whichever wire is for monitoring to the cpu fan header, but which wire/pin is it?
