      [antiX-22]

      My fan does not appear to be working correctly. Occasionally it will kick in if the CPU hits close to 90C, but only for a split second, which is not what should be happening. I do not really let it even get to 80C, I just tested it a few times to see when it would kick in.

      I’ve ran the BIOS diags thoroughly, multiple times and updated to the latest version of the BIOS [A24] and even restored default settings. Nothing seems wrong there.

      I’m unsure where to go next, as I’m new to this. I tried doing some research but haven’t had much luck figuring this out so far.

      Any help would be appreciated. Please let me know what you may need.

      TIA.

      Edit: For additional context, here are the outputs from watch sensors

      acpitz-acpi-0
      Adapter: ACPI interface
      temp1:        +25.0°C  (crit = +107.0°C)
      dell_smm-virtual-0
      Adapter: Virtual device
      Processor Fan:    0 RPM
      CPU:            +50.0°C

      ACPI is a static 25C – this never changes.

        Hi and welcome to the forum.
        Dell E6420 XFR, a highly ruggedised device.
        many reviews state it is very hot running. device with uncomfortably high vent and case temperatures.

        The only way I see to find some trustworthy clarity as to cooling system functionality is to test using windoze 10 and the specific dell
        diagnostic tools and checking system logs..

          Wife gave me a laptop cooling pad when my Panasonic Cf-48 ran hot with antiX 32 bit. I had to repaste the cpu with cooling paste to bring it down to 80F.
          But I don’t expect you to do that.

          One like so.

          I was careful to pick cheapest and ships worldwide.
          I still use it and have it for years. Just pointing out a easy option.

            I’ve already repasted with Arctic MX-6 with copper spacers, pasting on both sides. I also have a cooling pad. Yes, it technically helps circumvent, at idle with just a few Firefox tabs open it’s 40C-50C, but doing much else it bumps up the heat beyond what it should. I’ve updated to the latest version of the BIOS as well. I’ve ran sensors-detect, which only found coretemp. Updated everything in antiX, but not sure where else to go from here.

            I appreciate the input.

                This sounds like a hardware issue to me. Testing on Windows if you can would be best, but failing that a live USB of another Linux distro might shed some light. Try something quite different from antiX like Mint or Manjaro or something.

                Also, have you looked at the ArchWiki page on Fan Speed Control? It mentions a Dell-specific package that you might want to try out.

                There’s also the fancontrol component of lm-sensors described on that page. It’s availabke, but not pre-installed with antiX even though lm-sensors itself is.

                A more rough and ready method of testing fans without installing any additional packages is the /sys/class/thermal/cooling_device* interface.

                cat /sys/class/thermal/cooling_device*/type
                

                will give you a list of recognized devices and you can test them using a command like

                sudo sh -c "echo $(cat /sys/class/thermal/cooling_device0/max_state) > /sys/class/thermal/cooling_device0/cur_state"
                

                to see if manually enabling works at all.

                  Update: got it working.

                  Installed fancontrol, which wasn’t reading anything, and did some digging.

                  Found this post
                  https://www.reddit.com/r/linux_gaming/comments/15u6ghz/system_fan_control/

                  Which led me to this

                  Which led me to this
                  https://wiki.archlinux.org/title/Fan_speed_control#Dell_laptops

                  And led to this
                  https://askubuntu.com/questions/1227489/i8kctl-not-working-for-dell-inspiron-fan-control

                  After installing i8kutils and disabling the Dell BIOS fan control I ran pwmconfig, which was able to read things and generate a config file. Fans are working fine now.

                  Thanks, everyone.

                  Edit: had to add this line to /etc/rc.local:

                  sudo ./home/[username]/gitclones/dell-bios-fan-control/dell-bios-fan-control 0

                  I made a specific directory for it, so if this is ever copied by anyone, make sure to take note of that.
