Which temperature readngs can be trusted?

[1-2many]

I have just purchesed an e6600, and im having some heat problems,

in the Bios, after 10 mins the temp seems to idle at about 62 degrees

but while in windows, two temperature monitoring programs i am using show completely different results

Speedfan - has core 0 and 1, idle at 40-42 degrees

Coretemp - has cores 0 and 1, idle at about the same (42 degrees), with tjunction at 85 degrees??

Usually id trust the bios readings, but the difference is so great im a little confused
The Heat sink is definatly on properly, and the thermal paste applied properly, im using the stock fan

Interesting. Mine sits around 40 at the bios, and 36 with speedfan. That's some crazy high temps you're getting for some reason. I'm also using the stock fan btw.

Okay...found SpeedFan...now to figure out what the "Ghost" voltages AND Temperature's are.

So, how do I know that it actually is controlling the speed of my fan...just listen to it, or, actually monitoring with something else, like WARPSPEEDER at the same time!?!
