I havent read the whole thread, but dude, how many posts do you want to make rofl.
If you have a zalman and your idling @ those temps, either
learn how to apply paste or mount a heatsink
Make sure your motherboard isnt bending badly
How hot is your room?
Failing those, youve either got a bad sensor, or you H/s is screwed or your chip is making little or no contact with the IHS
does the base of your heatsink feel warm at all?
