I have still problem with fan on my ThinkPad T440s. I spent lot of time with googling and trying diferent configurations but my problem is still persit...

My thinkfan service probably service works:

sudo service thinkfan status 



● thinkfan.service - simple and lightweight fan control program

   Loaded: loaded (/lib/systemd/system/thinkfan.service; enabled; vendor preset: enabled)

   Active: active (running) since Wed 2019-01-16 17:17:01 CET; 1 day 14h ago

But after few minutes after restart OS is my fan so loud and run with full speed:

cat /proc/acpi/ibm/fan



status:     disabled

speed:      65535

level:      0

commands:   level <level> (<level> is 0-7, auto, disengaged, full-speed)

commands:   enable, disable

commands:   watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))

Speed of my fan everytime 65535 (without any changes).

Temperatures on my Thinkpad are fine:

sensors



thinkpad-isa-0000

Adapter: ISA adapter

fan1:        65535 RPM



acpitz-virtual-0

Adapter: Virtual device

temp1:        +35.0°C  (crit = +200.0°C)



coretemp-isa-0000

Adapter: ISA adapter

Package id 0:  +35.0°C  (high = +100.0°C, crit = +100.0°C)

Core 0:        +30.0°C  (high = +100.0°C, crit = +100.0°C)

Core 1:        +33.0°C  (high = +100.0°C, crit = +100.0°C)

But when i try command: dstat --cpufreq --fan --thermal i see "curious" error:

Module dstat_thermal failed to load. (Needs kernel ACPI or IBM-ACPI support)

dstat --cpufreq --fan --thermal

In files: /etc/modprobe.d/thinkfan.conf and /etc/modprobe.d/thinkpad_acpi.conf (i don't know which file i have to use, because in tutorials and topics on internet are used both files).

options thinkpad_acpi experimental=1 fan_control=1

Bios was updated to latest version 2.50.

I tried it with kernels 4.20.0 and 4.15.

Please, have you any ideas what i can do? Or is a HW fan problem?
I am still linux HW beginner and i don't knowledge to solve it :/

Thanks for any ideas.

UPDATE

New information (i don't know if is relevant):

sudo service fancontrol status

And when i use command pwmconfig:

sudo pwmconfig

...

...

Testing pwm control hwmon2/pwm1 ...

  hwmon2/fan1_input ... speed was 65535 now 65535

    no correlation



No correlations were detected.

There is either no fan connected to the output of hwmon2/pwm1,

or the connected fan has no rpm-signal connected to one of

the tested fan sensors. (Note: not all motherboards have

the pwm outputs connected to the fan connectors,

Thank you.
