Ok. Fan3 is disabled because the chip is programed to disabled - (IO pin) > Here's another iteration of the driver, please give it a try: It loads now. I have moved my extra fan to some other connector, now it is fan1 for w83627EHF chip. ATK0110 ATK0110:00: removing... ATK0110 ATK0110:00: atk: adding...

I have loaded/unloaded the driver several times before I checked the dir, so maybe is something wrong? Does it show up in your /sys/class/hwmon? Thanks, Rudolf
