what is your img?
because, to my knowledge, the only img where they forgot the fan control is the NG 2:07
and if so I am attaching a plugin:
Copy the plug-in "fancontrol" to / bin (755 attributes) and replace the rcS.local in / var / etc After a restart of the fan shoulderstand executed with speed = 1 ..
but at the same time I would recommend you put a newer img
