Trust MBM5 and sandra vs winbond hardware doctor??

Winbond hardware doctor shows temps of 47, and 33 C (smp). Which seems really off to me. So i looked at sandra and it said both temps are 39, then i dled mbm5 and use the iwill dpi533 wizard and it says both are 39. So who do i trust??

What does your bios read ? ive never went off sandra for temps much i usally get some messed up temps
