I'm user of Ubuntu 20.04.2 LTS, Gigabyte B450 AORUS ELITE ATX v2.
I tried to check temperature of my CPU but sensors showed nothing. I did sensors-detect, with "yes" everywhere and it did not help.
I have installed this: https://github.com/ocerman/zenpower and see:
Is that my CPU data? In BIOS my CPU voltage is set up to 1.3V, here is another result.
