No CPU Temperature

  • Hello,
      I can't monitor the CPU temperature using pfSense version 2.1 Release (i386) (upgraded from version 2.0.3).
    The PC is a HP DC 7700 (Intel Pentium D 945 Processor (3.4-GHz, 2x2MB L2 cache, 800-MHz FSB))

    What I did is:

    1. Add coretemp_load="yes" to the file loader.conf.local
    2. Set System/Advanced/Misc/Thermal Sensors to "Intel Core …"

    but the widget on the dashboard says "No Thermal Sensors data available.".

    I was trying to dig a little bit, and when I run from the console:

    kldload coretemp

    I get a:

    kldload: can't load coretemp: File exists

    and that should mean that the module has already been loaded.

    If I run:
    sysctl -a | grep temperature
    I just get no results… :S

    When I boot pfSense on that machine I see:

    Sep 27 09:03:36	kernel: est0: <enhanced speedstep="" frequency="" control=""> on cpu0

    Anyone can figure out why I can't monitor the CPU Temperature?


  • Netgate Administrator

    The Pentium D was still based on the Netburst architecture and the coretemp module only works with Core based CPU.

    You would have to try to use mbmon to read temperatures. There are a few threads about intergrating it's output with the dashboard widget.

    You may be able to read the ACPI temperature. Is it enabled in the bios?


  • Hi Steve,
    thank you for your answer… unfortunately both solutions didn't work...

    mbmon -c1

    No Hardware Monitor found!!
    InitMBInfo: No error: 0

    sysctl -a | grep therm
    sysctl -a | grep temper

    return no results… :(

    Ok, I got it, I will upgrade my firewall sooner or later... :D

    EDIT: and yes, ACPI is enabled in the BIOS setup, and recognized during the boot... (ACPI APIC Table: <compaq broadh2o="">)
