Intel TAT vs. BIOS temp reporting

It was suggested that I try the Intel Thermal Analysis Tool (TAT) to stress my E6400 and check temps as opposed to running Prime95 and using the Gigabyte tool to check the temps.

I downloaded it and it is a nifty little tool. But the temps it reports do not agree with the BIOS, nor the Gigabyte monitoring utility. Not even close.

Bios and the GByte tool report a 30C idle temp. Intel TAT reports 46C IDLE! If it was 1-2 degrees I'd write it off to the Computer Gnomes, but 16C? That's a BIG difference.

I do trust Intel to write a tool that can read the thermal probe in their own CPUs, but I also trust the MB manufs to know their own boards. That said, I know that Asus (for example) has had probs with some of their older S939 boards reading very high, but I've not read anything about the Gigabyte DS3 reading LOW.

Anyone have similar probs? Motherboard is a Gigabyte DS3/BIOS F7, if that helps.

Here's the tool if you wanna mess with it. (only works on C2D CPUs, FYI.)

Pic of the utility running. Note the temp diffs b/t the two reporting utilities!

Also, the utility says I have a Pentium M 😕
 
Yeah, you've got a point, Baked. But what a temp diff b/t the two! :Q I guess that just verifies that I really need better cooling than the stock HSF supplies.
 
CoreTemp reads from the same sensor as TAT, and reports very similar if not identical temps. I'd trust the on die temp more. With good cooling, my core temp is 32C, which is more believable than 20C from the BIOS reading.
 
Thanks for your help, Baked. I just ordered an Arctic Cooling Freezer 7 Pro, so that should help things out quite a bit.

In days of yore (Socket A, I miss you) there was always some discrepancy b/t BIOS reported temps and software utility (i.e. MBM) reported temps, but the delta was never this big. Seeing the temps reported by TAT was a real eye opener.
