So there is no 1:1 relationship between fans connectors and fan attributes. The GPIO pins used vary from board to board. There are some possibilities to support this, such as to modify the fancontrol script to also support setting gpio pins (if there is a gpio driver for the given HW), or to somehow implement the necessary support in the kernel. But those are all not really good solutions, and there are some questions if it can be made to work reliably in the first place. The AIDA64 folks tried to implement it but gave up (see http://forums.aida64.com/index.php?/topic/386-asrocks-fan-controller-sensor-trouble/), which is not a good sign.
