Note that fanX_input is always a read-only file, so writing to it isn't going to do anything. fanX_output is not a standard attribute for hwmon devices, it shouldn't be there in the first place... The applesmc driver doesn't see to follow the standard interface, so it's probably best to not assume too much. -- Jean Delvare
