Thank You, Guenter. Please, how could I correct that?


Something like

chip "k10temp-pci-00c3"
	compute temp1 @ + 10000, @ - 10000

to correct the reported temperature by 10 degrees C.

But please don't top-post.

Thanks,
Guenter

Hi,

I have an AMD A8 7600 (socket FM2+). The sensors command gives wrong values; after boot, CPU has some 8 degree Celsius, after few minutes of runtime it gives this:

$ sensors
radeon-pci-0008
Adapter: PCI adapter
temp1:        +40.0°C  (crit = +120.0°C, hyst = +90.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +40.5°C  (high = +70.0°C)
                        (crit = +80.0°C, hyst = +79.0°C)

(...althought going into BIOS shows some 70 degrees)


CPU sensors on those CPUs are very unreliable. You can try to correct
the reported numbers by adding configuration data to /etc/sensors3.conf.

$ sensors-detect

Please, is it possible to correct this just by tweaking some values in conf?
