during BIOS, your speedstep is disabled, so CPU runs at full speed (max frequency) and all cores enabled.
If you configured your windows correctly, your CPU should slow down and down voltage automatically at idle. Hence the reduction in temp.

Thanks. I never thought of that.

Just a follow up, I've run a few stress test on my CPU and after awhile my temps got up to 65C. Then when I shut the stress test down it instantly goes down to mid 40s and slowly goes down from there back to mid 30s. How the hell can something instantly lose 20C? Even if it is accurate, I can't see how such a dramatic drop can be good for the CPU. I'm weary of performing more test now.

Your cpu is designed to handle that... You think intel for all those years they made cpus, you are the first to notice temperatures change fast?

Why it changes so fast is because it is reading a temperature from within the actual die of the chip.

I'm not sure what to assume. I've had a Q9550 prior to this on air cool and I don't recall seeing such a dramatic drop.

What is it about the die of the chip that gives it the ability to drop 20C instantaneously?

Ok, lets say that you have an electric stove top, and that the coils are the cpu die, and your hand is the thermal probe. You have the stove set to high, and you touch the coil. Your hand gets hot instantly. That is how programs like core temp read. Now, you have the same hot burner, but you put your hand a few inches beside it. You won't notice a temperature change as fast, and it won't be near as hot. That is what most programs, and your bios is reading, a sensor next to the cpu die, but not in it like the other.

Thanks Roadhog, but I'm wondering what makes the die able to drop temps so quickly. Like an electric stove top's coils, even if you cut all electricity to it you won't see a dramatic drop instantly. The kind of drastic drops would be more comparable to a microwave but it's not based on the same principle.

Well the cpu is being cooled, and its also very very tiny and the material doesn't retain heat...

My bios reports 50c for the CPU too. And core temp etc reports in the low 30s. I wouldn't worry about it. Your CPU is running well in it's limits.
