[SOLVED] lm_sensors: Ryzen CPU temperature

hello,
i have a Ryzen 5 5600G and i would like to know CPU temperature.
this is lm_sensors output (after Linux startup):

k10temp-pci-00c3

What is the temperature of the cpu? CPUTIN or TSI0_TEMP?
why SYSTIN is 118°C? o_O it's a bug?


EDIT:
temperatures after playing 10 minutes of Zelda botw 720p (cemu):

Re: [SOLVED] lm_sensors: Ryzen CPU temperature

k10temp and TS10_TEMP are identical. k10temp is the official driver/temperature that AMD uses for speed/boost calculations.

nct6973 is the microcontroller on the motherboard which checks multiple sensors. (if you look more into lm_sensors, you can rename the inx channels to other names that make more sense)

tldr: k10temp is the number you want to be checking


Just trying to figure things out in this world
