Tcase/Tjunction/Temp question
I'm trying to figure out why my Tcase temp is higher than my TJuntion temp. I'm assumming one is being reported incorrently, but which one is more likely to be the culprit. Here's my situation:
Tcase = 37 (32 in BIOS upon restart) & 55 (up to 62 with TAT)
Tjunction = 32 & 50-55
Ambient = 20
Chipset = Nvidia 680i
C2D = e6400
CPU Cooler = Arctic Cooler Freezer Pro 7/Ceramique
Frequency = OCed to 3.2 (linked/synced with 1600QDR)
Load = Orthos/TAT/OCCT/3DMark2006
Motherboard = EVGA
Vcore = 1.25
I'm wondering, of course, why my Tcase is higher than my Tjunction. Is my TJunction more likely to be being reported incorrectly than my TCase? That is, is it likely that my Tcase is correct, meaning my TJunction Idle/Load values are really more like 47/70-75. The Tjunction values reported above are consistent across TAT, CoreTemp, and SpeedFan. Any guidance would be much appreciated.

The correct temperature "terms" according to Intel
Here.., what a picture worth for .... according to Intel straight from their tech journal.

Red = Thermal goop
Brown = IHS
Ok, to cut through all the crap...
So, should I rely on SpeedFan's reported CPU temps and completely ignore readings from the Core such as are reported in TAT, CoreTemp, and, also, SpeedFan (it's the only program I know of that reports all three). Either way, it seems we're in agreement that CPU temp is read off the top of the IHS and core temps are read from a diode within the chip itself, right. So, back to my original question. Logic tells me the temp read from the IHS should be lower than the temps read from the core. So, why is SpeedFan showing a higher CPU temp than it does temps for both the cores? Any thoughts that don't involve ambiguous suggestions that there's no way to gauge temps anymore would be much appreciated :) .
