Hi
@DeLorean:
A i3 or i5 can have always 1 or 2 core warmer then the other core's.
These i3 and i5 cpu's have a embedded Intel HD graphic card, when this graphic card is under load,
the graphic part of the cpu gets hotter and this can rise up cpu core(s) next to it.

I get the same thing on a Intel Pentium Processor N3700, it's just the way they are sometimes, providing no core is exceeding the maximum ratings there is nothing to worry about. I've been running my system 24/7 for almost a year and it is rock solid.
Sometimes the cores are heated by other parts nearby, other times a thread or process is set to have an affinity (will always run) on the same CPU core, or the CPU chooses a core to constantly tick over to allow others to sleep longer, so the result is the other cores run cooler and one core runs warmer, exaggerating the differences.
