vcore in BIOs or monitoring software?

Just wondering which one to believe? In the BIOS I've set it to 1.52V. coretemp, CPUZ and ASUS PCProbe all say 1.47V. So which is it? It's with the system in my sig.

EDIT: Also, which CPU temperature should I worry about? The two core temperatures in coretemp and TAT are quite a bit lower than the overall CPU temp that speedfan and ASUS PCProbe detect.

the volt differences are due to vDrop, happens on a lot of boards, the real-life value you describe is 1.47v, i.e. the actual volts going through your cpu. Another concern is vDroop, where (potentially) your 1.47 may further decline under load.

That could be the same as what I am seeing with my Gigabyte P35 board. I set 1.45 (for example) in the BIOS and then find 1.40 in CPU-z which drops slightly to 1.392 when running Prime.
