No CPU Temperature

mdima

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:

Add coretemp_load="yes" to the file loader.conf.local
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: Origin = "GenuineIntel" Id = 0xf64 Family = f Model = 6 Stepping = 4

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

Thanks,

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
returns

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

and
sysctl -a | grep therm
or
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="">)

Thanks,
