coretemp or msi dualcore centre, correct temps

[m4r71n]

i was wondering which program i should be taking as the more likely to be accurate, right now core temp is showing 22/20 and dc centre is showing 30. i've always thought core temp was pretty much spot on before but i dont see how they could be so far different if that was the case
