Trying To Set Up Thinkfan on Lenovo Thinkpad Yoga x380

I am having some trouble getting my thinkpad to read and control the fans. Following the wiki page https://wiki.archlinux.org/index.php/Fa … m-sensors), I have done the following...

1.) Install lm_sensors. I then run "sensors-detect" and everything looks normal (I can give this output if need be). However, I then run "pwmconfig" which yields...

 There are no usable PWM outputs. 

This is the output for "sensors."

 BAT0-acpi-0
Adapter: ACPI interface
in0:          17.32 V  

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +38.0°C  

nvme-pci-0500
Adapter: PCI adapter
Composite:    +37.9°C  (low  = -273.1°C, high = +80.8°C)
                       (crit = +81.8°C)
Sensor 1:     +37.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +35.9°C  (low  = -273.1°C, high = +65261.8°C)

iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +32.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +41.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +41.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +41.0°C  (high = +100.0°C, crit = +100.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM
 

I have run a few CPU stress tests, and no matter what the CPU temperature is, the fan speed stays at zero. I don't have this issue when I boot into windows instead of Arch, which is odd.

2.) I tried to install Thinkfan based on the same wiki page. When I run "cat /proc/acpi/ibm/fan," I do not get the desired output...

status:         disabled
speed:          0
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))

However, I can still start Thinkfan using "thinkfan -n" or "systemctl enable thinkfan" and "systemctl start thinkfan," and it yields legitimate temp readings and appropriate levels (despite the fact that I can hear the fan is NOT spinning).

Has anyone had this issue before? Thank you.

Re: Trying To Set Up Thinkfan on Lenovo Thinkpad Yoga x380

Thank you for your reply! I tried that wiki entry before, but couldn't quite get it to work. I am not sure if my chipset name is correct. I used "coretemp-isa-0000" given by "sensors" to populate the /etc/sensors.d/fan-speed-control.conf file.

$ sensors
BAT0-acpi-0
Adapter: ACPI interface
in0:          15.12 V  

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +37.5°C  

nvme-pci-0500
Adapter: PCI adapter
Composite:    +31.9°C  (low  = -273.1°C, high = +80.8°C)
                       (crit = +81.8°C)
Sensor 1:     +31.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +31.9°C  (low  = -273.1°C, high = +65261.8°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +40.0°C  (high = +100.0°C, crit = +100.0°C)

iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +32.0°C  

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM

Here is my /etc/sensors.d/fan-speed-control.conf file.

chip "coretemp-isa-0000"
set fan1_div 4

When I run "sudo sensors -s," I get an error indicating that my chipset name is not correct...

Error: File /etc/sensors.d/fan-speed-control.conf, line 2: Unknown feature name
coretemp-isa-0000: No such subfeature known

Is there a better way to find the chipset name? I could not figure out what this name looks like after searching around for its syntax.

Hi @useMoreArch
could you ever solve this problem?

The OP has not been back since 2020, so I don't think you are going to get an answer.

Please do not necrobump. Instead, start a new topic, and refer back to this one of you think it applies.

Closing.
