HWMonitor - CPU vs Core vs Package temps

[DEDRICK]

So I undervolted my 4790K by (- offset 0.075) to try to shave few more degrees off.  I stress tested with Intel XTU, all 3 maxes report a different number, 62 CPU, 63 on the cores and 64 on the package.

 

I'm fairly happy with both my idle and max load temps but I'm curious though, what temperature do you all look at?

 

CPU is the socket temp on the motherboard, the core temps are each individual core and the package is something.

My 4790K idles at 32C, and at 100% load hits around 55C, while overclocked to 4.8ghz @1.285V

You look at Core#0-3. Those are temps for individual cores. Package is average over all four and updates bit slower.
