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?
