What CPU temp reading is the correct one?

[Pareeeee]

I'm attempting to overclock my old PC and the BIOS is showing a different temperature than all of the sensors within HWINFO64. I'm assuming because once the OS starts it uses more CPU than the BIOS interface does.

Anyway, I'm not sure which one of these I should be looking at for my CPU temp.

CPU: AMD Athlon(tm) X4 860K Quad Core Processor
RAM: 16.0 GB
Mobo: GIGABYTE F2A78M-D3H
OS: Windows 10 Home 22H2

Older AMD CPUs don't feature a reliable internal thermal sensor. Instead one needs to rely on the sensor in mainboard but this one usually provides only the external (socket/Tcase) CPU temperature.

Thank you for the information. Do you mean the one that's reading 26 degrees in the photo I posted? Is that the correct one to look at?
How many degrees does one need to add to the reading to have an approximation?

Yes, the 26°C one is under the gygabyte section so it's the motherboard socket sensor.

Old memories of those CPUs claiming to do sub-ambient cooling ^^

Thank you!
