Need a decent temp monitor that'll work with Vista

[Agentbolt]

I recently built a new Vista PC, with an E4300 CPU. The BIOS is displaying the CPU temp as ~30 degrees C, whereas the only temperature monitor I can find that'll even run (Intel TAT) is displaying the temp are idling at around 50 degrees C. I have no idea which to believe so I'm looking for a third program to point me in one direction or the other. I'm using the stock Intel HSF with the original crap thermal paste replaced with Artic Silver 5 (followed the directions pretty darn thoroughly, I feel it's installed properly) Other specs as follow:

8800GTS vid card
2 gigs RAM
Gigabyte GA-965P-S3 (Rev. 1) Motherboard (F6 Bios, no floppy drive currently to update it, EasyTune5 doesn't work with Vista it seems)

I haven't OCed or anything. Gigabyte's own monitoring software doesn't appear to run properly under Vista (getting a bunch of .dll errors). Anyone found one that works well? 50C for an E4300 while idle is pretty bad.

One mystery solved, another pops up:

CoreTemp started working after I flashed the BIOS to the new F10 (The Gigabyte @BIOS program worked great) and is showing both cores switching between 35-40 degrees C. Still not super, but not atrocious either. Probably about as good as I can expect from a stock HSF that hasn't been burned in yet.

TAT is now showing 60 degrees C at idle now, though. Why is it so hard to figure out how hot your processor is really running?
