I am trying to monitor the temperatures and fan speeds of my desktop PC (Intel i7-7700k + Asus TUF Z270 Mark II + GeForce GTX 1060) through lm-sensors but sensors only outputs CPU info. I run several times sensors-detect, answered YES to all the questions YES/no, loaded the corresponding modules in /etc/modules but nothing works.

The modules it seems that I have to load are coretemp, nct6775 and i2c-i801. I put them in the /etc/modules file, restarted kmod, reboot the machine, all things, and nothing works. I only see the CPU temps when running sensors. This is the output:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +43.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +38.0°C  (high = +80.0°C, crit = +100.0°C)
Core 1:        +40.0°C  (high = +80.0°C, crit = +100.0°C)
Core 2:        +39.0°C  (high = +80.0°C, crit = +100.0°C)
Core 3:        +39.0°C  (high = +80.0°C, crit = +100.0°C)

Nothing more. Nothing related to fans, to PCH temperature, motherboard, anything.

Does anyone know what is wrong and can help me please?

Thank you very much

  • Depending on the computer, that might be all the sensors on it. Have a couple older Acers that is all they had, have a better Dell and have quite a few temp sensors and fan control. Add your computer model and make to your question, and someone can tell you more. – crip659 Aug 25 '20 at 22:49
  • It is a desktop PC Intel i7-7700k on an Asus TUF Z270 Mark II motherboard. I will put it in the question also – Javier Aug 25 '20 at 22:58
  • Would think that would have more sensors, but need someone that has one to tell you more. – crip659 Aug 25 '20 at 23:05
  • It does. In windows I have info about PHC and motherboard temperature sensors, and 4 fan speeds. – Javier Aug 25 '20 at 23:07
  • This link has some ideas to help. https://askubuntu.com/questions/1145968/how-to-see-all-my-fans-in-sensors – crip659 Aug 25 '20 at 23:20
  • Yes I saw it. Adding acpi_enforce_resources=lax to grub cmd line solves the problem, but it also seems that exposes the system to some inestabilities. It is a temporal fix, but not the solution to the problem :( – Javier Aug 26 '20 at 10:19
  • Will need someone else with more knowledge to jump in now. Found that with google. – crip659 Aug 26 '20 at 10:39
  • Can you be specific on the instabilities? That setting just allows drivers to access resources that are claimed by ACPI, which is needed to access the Nuvoton chip. I have a similar board and do not have any issues with this setting. – rtaft Aug 26 '20 at 13:10
