I see you have an AMD APU. Good luck getting an accurate temp of the cores. I have had 3 APUs, and several FX processors. I have yet to find a program that can read the core temps. Not even AMD's own Overdrive reads them. Usually the tmp0 is close to accurate, though. See if your MB disk comes with a utility pgm that can read the temp.
I seriously doubt those temps you show are correct.
