I have observed up to a 10c reduction in socket temp by placing a fan pointing at the back of the socket. That did help to lower the core temps as well so it would seem they are indeed linked.
EDIT: I read your guide and I feel there is no conflict with what I stated. What are your thoughts on the lowering of the socket temps in relation to lower core temps?
I just saw a system today where the socket / "CPU Temp" was reading 15-20C higher than the actual temp and from idle to that point it was still between 10-15C off, so it's just a variable from system to system and not a good indicator of anything. I've also seen systems where "CPU Temp" read higher at idle than it did at load, so again the TYP 7-10C rule doesn't always hold true.
So "CPU Temp" will always be off, by how much depends on the mobo and the sensor as well as other factors, where "Core Temp" does exactly what it was designed to do - which is report correct load and peak temps so that you can stay under the recommended limit for your chip.
As I mention in my guide, idle temps for both values will be inaccurate. Which IMO, doesn't matter, because do I really care what my idle temps are if I know that under load it's only 38C? And btw, just because "Core Temp" equalizes at 45C, doesn't mean it's completely inaccurate up to that point. As long as the CPU is under load, the equation works to be within 5C, then past 45C it's within 1-2C. The only flaw is that it can't do straight idle temps, because the equation factors certain aspects of load and it's effect on the chip itself pertaining to heat.
