Which is right, CPU temp or Core 1/2 temp?

Under Dual Prime95, I get several different temp readings using Scythe Infinity on E6400 overclocked to 3.2Ghz, 1.3825vCore, 400fsb on a DS3


Everest: Core 1 and core 2 are 57, and cpu temp is 49
CoreTemp: 59C
TAT:56C

Idle Temps:
Everest: Core 1 and core 2 are 45, cpu is 31C
Coretemp 45/44
TAT 46/44C
Speedfan doesnt give me any voltages/temp readings that make any sense

Are these temps too high when using said settings and heatsink in an Antec P180 case? A week ago these temps were reading 2-3C lower, would a reseat of the heatsink be needed? I would appreciate any tips to tame these temps.

Is 1.68 Vcore correct? This is dangerously high. Could you have meant 1.48? Intel's Vcore spec is 1.3525, so if you overvolt by 10%, then Vcore = ~ 1.488.

So if my BIOS is idle at 33C, speedfan 4.32beta is idle at 33C, and speedfan under full load(TAT/2xPrime95) is 44C, I'm well within the safe temps? I understand the overclocking part fine, Its the wide array of different temperature sensors that is mind boggling.

And I correct myself, Vcore was at 1.3825

Yes, you're correct. You are well within safe temps, and yes, 1.3825 Vcore makes sense. If your RAM is DDR2 800 Mhz 4-4-4-12, then you have headroom to OC higher. For example, if you increase your CPU frequency to 3.4 Ghz at 425 Mhz FSB and DDR2 850 Mhz with Vcore 1.4825, then your temps should increase by ~ 6c, which would still keep you within safe limits. 8)
