Wrong cpu temperature report with athlon 5350

[Limbi]

Hi,

The temperature reported in the dashboard is way lower of what it should be. When it was actively cooled the cpu temp was lower than ambient temperature, it is impossible. Please fix that or show me a workaround.

2.3.2 is doing this also. I recently built a new box with a 5350 and noticed it.

It did even on previous release, 2.3.2 and 2.3.1 sure.

What my cpu isn't really running at 11 degrees? ;D

The FreeBSD drivers report only what the hardware tells them, they are not aware of the adjustment factors for various motherboards that need to be applied to the raw values to get the real temperatures and that's why the numbers make no sense as absolute numbers.

If you "know" the difference (offset)

You can use the "shellcmd option" and adjust/tune the value

I've done this way with my "C70M1" MB

<shellcmd>sysctl -a dev.amdtemp.0.sensor_offset:-18</shellcmd>

Go to    System>Advanced>Miscellaneous and check you have AMD selected under the Cryptographic & Thermal Hardware header on the Thermal Sensor drop down.
