Shiny sticker is a heat pad, they are one time use - after removing radiator once its ruined (like copper crush washers) and might need replacing with another one or paste.

How accurate should I expect the reported temps to be?

As accurate as the hardware is as it's easy for software to read the temperatures and report the value.

It's impossible to assign meaning to 65°C - 67°C without knowing the ambient/case air temperature, how hot was everything else?

When idle my CPUs were 47.0°C + 41.5°C with the MB @ 32°C, the Thermaltake SPG-650D-G PSU @ 36°C and the QUANTUM ATLAS IV 9 WLS @ 35°C

Thanks, I will scrape the one time heat pad off and re-apply some thermal paste. Back in the day I skipped coppermine and when straight to Socket A T-bird. That said, this coppermine is running hotter at idle than my 1100Mhz T-bird atm. I always thought the Athlons ran hotter than anything Intel.

Was curious to know if there were any known concerns with the hardware sensors used.

The only other reading I have from the machine is the MB . It reports around 29°C. Room temp is under 21°C

Thanks again to you both for the input.

Well, some good news. After removing the heat pad, cleaning the heatsink of residue, and applying a little bit of good ole arctic silver, my idle temps are down significantly. After a few runs of 3dmark and some Q3 demo passes, it does not get above 49°C. Needless to say I have very happy with the marked drop in temperatures. Thanks again for the input.
