I suspect the fan leads are getting the full voltage but the fan only speeds up if it gets the right PWM signal. When connected to PWN_FAN the CPU fan rpms were in same i.e. I hoped this would finally do it but this didn't get the CPU fan to full speed either. ![]() So try plugging the CPU PWM fan into this header and you should get the desired result. However in addition the PWR_FAN header also supplied an uncontrolled 12V so any fan plugged into it, 3 pin or otherwise, would run at full speed and its rpm could be monitored. This was a 3 pin header designed as its name suggests to monitor the speed of a power supply fan (there were PSUs around at the time which had an external lead which you could plug into this header).
