Hi,
I'm not sure it's the right place to ask my question, if it's not please
feel free to indicate me the post appropriate place ;)

I have some problems configuring the fancontrol script, because each time I
shutdown my computer, when I reboot my /sys/class/hwmon/ is different
(subfolders hwmon? are numbered differently).
What is responsible for this order ?
How can I configure it to have i fixed order ?

my motherboard is a Asus MN2 SLI DELUXE with AMD CPU
below some results:
