CPU Temperature versus Core Temperature in Hardware Monitor

[xproofx]

Can anyone explain the difference between the cpu temperature reading and core temperature from CPUID Hardware Monitor from the screen capture below and also at a cursory look at my values and knowing I am running stock, if I should be concerned about anything?

Thanks for the assist.

Processor temperature is the external temperature. It is usually the temperature underneath the chip, or measured by a thermal diode on the CPU die.

The processor temperatures for the cores is reported by the sensor that is internal and located in the part of each core that was identified by intel to be the hottest of part of the cores.

Which one should I be more concerned with and recognizing these temps were taken at idle with a stock fan does it appear it is running too hot?
