CPU temp at 122c

Troubleshooting
21

There’s a wierd thing happening, the system appears to be changing the file that the CPU temp gets written too after a reboot.
It’s now on temp7_input

Why does it change that…?

22

not sure if this is something we could influence but @MichaIng might now it better than I.

23

Hmm, there was no kernel upgrade in the meantime, which could cause this? The same sysfs entry should be used on every boot session.

Can you check lm-sensors:

apt install lm-sensors
sensors

It might show some indicators about which sensor is for which device.

Hi Michalng
Sensors for the CPU are:

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +31.2°C
Tdie:         +31.2°C

It’s accurate, when I run a stress test the temperature rises in line with expectations.

Of if you want everything:

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +31.2°C
Tdie:         +31.2°C

nvme-pci-0100

Composite:    +28.9°C

This is getting frustrating
On a new machine, the temp is 122c and no amount of hacks will show the real temp.
Neofetch does, but not the dietpi detector.
