Fancontrol error: echo: write error: invalid argument

How can I manually change Fancontrol speed? I could use the command:

echo level 7 > /proc/acpi/ibm/fan

But I have an error:

echo: write error: invalid argument

My /etc/modprobe.d/thinkpad_acpi.conf :

options thinkpad_acpi fan_control=1

And always:

cat /proc/acpi/ibm/fan
status:     enabled
speed:      0
level:      auto

(I use Arch on Thinkpad P15 Gen1)

Check values of your interested module:

# systool -v -m thinkpad_acpi 

What's reporting?
