wow i'm confused

I just dont know what my actual cpu temperatures are b/c i get so many different temperature readings from different hardware temperature managing software. Heres what i'm getting:

PC wizard:

CPU temp: 35c
core 1: 45
core 2: 44 (why would it say CPU temp 35 but the cores are in the 40s?)


SpeedFan:

core 0: 29c
core 1: 31c
core: 53c (again, why would core be 53 if core 0 and 1 are around 30c?)


hmonitor:

cpu: 33c
core1:37
core0: 30


BIOS (my mobo BIOS):

cpu: 37c



So what do you guys think? Is PC wizard giving me incorrect temps?

All help is greatly appreciatedwow i'm confused
