Processor temperature.

I have a mixture of mostly AMD and a few Intel based computers. I run boinc on 
them which runs at 100% utilization. The sensors package gives me an indication 
of the temperatures, but I'm not sure I'm using the right sensor to measure with 
and what that temperature should be.
So, I'm asking is there a place where I can go find the proper sensor to work 
with, given the processor make/model and MB make/model, along with the maximum 
values for temperature?

For example, on this computer:
openSUSE Leap 15.5, all the computers have this in common
AMD Ryzen 7 5700G with Radeon Graphics
ASRock B550M-ITX/ac
CPUTIN: +74.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = thermistor
The sensors command show multiple temperatures and I guessed this was the one to 
track.

Any assistance would be appreciated.
