Disable cpu fan on GuixSD

[znavko]

Hello! I have Lenovo G50-30, that had passive cooling by default, but I've inserted cpu fan there, and it works.

But I need to switch off cpu fan. Here [1] said about config in /etc/sensors.d/fan-speed-control.conf and also pwmconfig, I am complicated with this.

1) How does lm-sensors get config, where to place it in GuixSD?
2) What module do I need for pwmconfig?


# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +39.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +39.0°C (high = +105.0°C, crit = +105.0°C)
Core 2: +42.0°C (high = +105.0°C, crit = +105.0°C)
Core 3: +42.0°C (high = +105.0°C, crit = +105.0°C)

# 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


3) Would you be so kind give me ready config for disable cpu fan while temperature less then 55 °C?
