Inconsistant Temp Readings MB vs OS Which do I trust?

[devren]

When I boot into my bios and load up the hardware monitor and chech my CPU temp, the tempeture increases substancially, stating normally and steadily increased, I watched it go all the way up to 60c before I left the bios and booted up into windows. So I boot up and the temp is still around 60 when I get into windows BUT once windows is done loading the temp quickly drops down to about 43-44 C and stays there or goes lower. (I'm using Asus PC Probe to check the temp in the os)

So for some reason does my computer not idle while its in the bios?
Or am I getting false readings as to what my idle temp is in the os?

So what would you say about the fact that in the bios my cpu temp says it goes to 50-60 c just sitting there watching the temp rise, and when im in windows the temp goes down to about 35-45c. Thats a 15c margin, which do you think is more likely to be accurate? or should I just not worry?

My load when not oced is about 45-50 and idle is about 35. I have a side fan and 3 case fans the mb temp never seems to get higher then 24c
What do you think?
