switch off cpu fan on lenovo g50-30

switch off cpu fan on lenovo g50-30

[znavko]

Hello! Sometimes I need my laptop Lenovo G50-30 is silent, need to switch off CPU fan.
Basically this laptop had no cpu fan but only passive cooling system. I had inserted cpu fan by my hands and there were fan power joint on the motherboard. This is nice. I hope Guix Linux-Libre has necessary fan control driver for my laptop.

There is package 'thinkfan' in Guix repository. Would you advice me how to config it and is it possible to switch off fan?

When I look at `git blame`, I find thinkfan is from 2016-04.  I find:

Re: switch off cpu fan on lenovo g50-30

[znavko]

Hello, Efraim Flashner! I want your support cause my question is not figuring out from the web.
For typing my config for 'thinkfan' need to write thinkfan.conf, and there, I think, it is necessary to define temperature control kernel module. 
After running `sensors-detect` (from 'lmsensors' package) this config file appeared:

# cat /etc/sysconfig/lm_sensors
# Generated by sensors-detect on Thu Jul  4 12:53:51 2019
# This file is sourced by /etc/init.d/lm_sensors and defines the modules to
# be loaded/unloaded.
#
# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or SPI).

HWMON_MODULES="coretemp"


As I understood 'coretemp' is that module I can use in thinkfan.conf.  I see `sensors` is using coretemp-isa-0000


# sensors
soc_dts0-virtual-0
Adapter: Virtual device
temp1:        +42.0°C  

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +60.0°C  (crit = +90.0°C)

soc_dts1-virtual-0
Adapter: Virtual device
temp1:        +42.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +46.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +46.0°C  (high = +105.0°C, crit = +105.0°C)
Core 2:       +52.0°C  (high = +105.0°C, crit = +105.0°C)
Core 3:       +52.0°C  (high = +105.0°C, crit = +105.0°C)


Ok. But I need to use 'coretemp' file from /proc as in example here [1]. But I do not know where is it:

# find /proc -name 'corete*'
# 


Please, can you help me?

I often turn to Debian when I have a problem like this one. In the
source (I assume in ours and not just in theirs) There's an example
folder with two example configs¹ so I'd suggest checking them out and
seeing if they look right.

Re: switch off cpu fan on lenovo g50-30

[znavko]

With thinkfan.conf.simple having this:

# thinkfan

ERROR: TpFanDriver: Initializing fan control in /proc/acpi/ibm/fan: No such file or directory


With  thinkfan.conf.complex this:

# thinkfan

ERROR: SensorDriver: Initializing fan control in /proc/acpi/ibm/thermal: No such file or directory


Linux-libre has no fan control module for lenovo g50-30. How to get it?

Re: switch off cpu fan on lenovo g50-30

[znavko]

As there [1] said  have no fan control module:

 pwm_fan sysfs-path

    Control a sysfs PWM fan. Many hwmon drivers that provide a `temp*_input' file also allow fan control, although there may also be drivers that are specific to either temperature reading or fan control. You can search for a PWM control file e.g. with `find /sys -type f -name "pwm?"'. Note that with PWM, fan levels usually range from 0 to 255, although besides a file like `pwm1' there may also be `pwm1_min' and `pwm1_max' that specify different (soft or recommended?) limits for a particular fan.


# find /sys -type f -name "pwm?"
#
# find /sys -type f -name "pwm*"
# 

Have you on your linux-libre?

yes. I ran, but thinkfan cannot use module:

# modprobe thinkpad_acpi fan_control=1

Say me how to type thinkpad.conf to use thinkpad_acpi module?

This is strange.  I can only do a Web search because I own no
Thinkpad.  I find

http://forum.notebookreview.com/threads/ubuntu-question-t420.603272/

They say:

“The cause: the file /proc/acpi/ibm/thermal no longer exists in the
affected models. The temperature sensors are moved to another location
in the sysfs thinkfan and she does not recognize.”

They point to a different sensor line in thinkfan.conf.

I assume thinkfan_acpi is listed in lsmod.

A bad alternative would be that you try using a different kernel version.

Florian

Re: switch off cpu fan on lenovo g50-30

[znavko]

I see this now:

# pwmconfig
# pwmconfig revision $Revision$ ($Date$)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/root/.guix-profile/sbin/pwmconfig: There are no pwm-capable sensor modules installed
