they are independant of each other. there is no set ratio of cpu voltage to cpu-nb voltage. however, you may find that bumping CPU-NB slightly may help with CPU clocks, and vice-versa.
occt shows the same value as coretemp. asus pc probe is monitoring your socket temps. it sounds about right that your socket is ~5 away from core (mine is ~6 away from core). both should be used so you can get an idea of where your temps are. HWMonitor and Everest will show you both.
