Wrong, but your statement considering the accuracy under idle/load is correct.I think there is only 1 DTS sensor for all your cores, not 1 per core.

So 1 sensor is able to report temperatures for all of the cores?Actually I am right (personally speaking) Phenom/Opteron/Bulldozer/K10 + only have 1 DTS sensor per package. not per core..

Thread got a bit derailed. The below 2 screenshots were just taken, the first is idle and the second is load. Easytune shows the motherboard sensor below the CPU socket, Coretemp shows the CPU sensor embeded in the CPU die, and HWMonitor shows both. The CPU is an FX8120 @ 4.0Ghz using a Silver Arrow (22C is current ambient).
At idle (first screenshot) Core temp reads 14C as does HWMonitor, this is the supposed core temp, the motherboard sensor reads 26C in Easytune and HWMonitor (TMPIN2). A delta of 12C between the CPU DTS and the Motherboard DTS.
At load (second screenshot) Core temp and HWMonitor read 35C for the CPU DTS, the motherboard DTS reads 47C. Again a delta of 12C. So the scales between the 2 DTS's are the same (if plotted the slope of the lines would be the same), however the CPU DTS must be wrong since the ambient is 22C and at idle it reads 8C below ambient which is impossible using air cooling (or water). The motherboard sensor at idle reads 26C, again with an ambient of 22C is much more believable.
The 1090T I had (recently sold) read the same way using an older model motherboard (890FX instead of 990FX), however it's DTS was further off, around 15C too low.
The point I'm making is the CPU DTS is an arbitrarily chosen value using the degrees scale, the value itself is meaningless without knowing how far off it is. Also each processor maybe different, again because the value is arbitrary (see white paper above).
I just installed speedfan to check myself but it doesn't read my core temp, only socket temp (on 990FX).
