Bug 1118961

Why do you have thinkfan.service disabled?

What do you have in /etc/thinkfan.conf?

Can you please post output of following two commands?

find /sys/devices -type f -name "temp*_input"

and

sudo thinkfan -n

I didn't notice that it was failing on my system to.

It seems like location of sensor files have changed.

After replacing the above sensors, it has started working fine again.

> Why do you have thinkfan.service disabled?

Because it is Fedora default policy for just installed services. I haven't yet enabled it, I just tried to start it,

Module thinkpad_acpi doesn't seem to support fan_control

It is not started because you have to manually set it up to work. It's failing because you haven't set it up properly.

> Module thinkpad_acpi doesn't seem to support fan_control

Let's make sure you have modules for thinkfan to work.

You should have a file /etc/modprobe.d/thinkfan.conf

cat /etc/modprobe.d/thinkfan.conf
options thinkpad_acpi fan_control=1

It will be safe to restart your system to load thinkpad_acpi

See my attachment to how to setup /etc/thinkfan.conf or this wiki entry https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_T420#Fans

Basically stick sensor in front of the sensors list you generated in the last post and append it above the temperature list in /etc/thinkfan.conf

Ok now it works.
I think that Thinkfan should compile on its own the thinkfan.conf file by auto retrieving infos of
>find /sys/devices -type f -name "temp*_input"

I have opened a new bugreport for that https://bugzilla.redhat.com/show_bug.cgi?id=1118993
