ok, which temp reading is my overall processor!

Ok so I read my temps from both PC Wizard 08 and SpeedFan. They each have a temp reading for each core, and when I'm torture testing it's understandable why they get up to 60-65c. But is the overall reading the one that says "processor Temperature"? Because that one one is always significantly lower than each core individually. It appears on both Speedfan and PC wizard. What is my actual temp, the avg. of each core or that reading?

if you're suggesting I should use these, I have Coretemp and use it often but even still it shows 4 readings.

Coretemp shows you four readings because you have a quad-core processor. Basically shows you the temp for each core. In essence, they average out to be your 'overall' processor's temps.
