Confused over CPU/Core Temp difference

[Resident]

It's not a major issue but I was wondering if someone could alleviate my confusion over the difference in CPU/Core temps.

Running Aida64 my CPU temp is reported at 34°C however for all 3 core temp readings I'm given a reading of 24°C

Why such a difference?

Dont look at the cpu temp, look at the core temps, thats the right one

So it's just a mis-read by what I assume to be the mainboard CPU sensor ?
