Okay naysayers, here's the deal regarding E4300 temps in simple English. The E4300 has a basis point for determining core temperature of 100C along with the new steppings of the E6300 and E6400 that are based on Allendale. The previous Conroe steppings had a basis point of 85C.
What does this mean? Current versions of core temp reporting programs under report the temp of these new chips by 15C. Check out this thread where the author of Core Temp basically says what I just did, and also says that the next version will fix this error:

Now, my CPU intermittently thermal throttles down during 100% usage because of the extreme heat at my settings. Adjusted for the 15C, I run at about 77C core temp. You can see the thermal throttling using the
RightMark CPU Clock Utility. Open up the main display, click on the arrow on the upper left hand corner, then select "Monitoring (CPU 0)" or "Monitoring (CPU 1)". The First graph shows set CPU speed in red and throttle speed in violet. At idle there might just be a couple of meaningless little blips in the throttle speed below set clock speed. Now run ORTHOS with "Small FFTs". You may immediately see the throttle speed start dipping down, and after a few minutes it might begin to spike down. If you are really overheating it could possibly dip down and plateau.
Still don't believe it? Open up Speedfan, click on the Charts tab, and then click on the Core 0 and Core 1 boxes. While running ORTHOS, after a few minutes watch how the core temps cant't hold a steady line, but instead is jump around within a couple degrees. That's thermal throttling cooling the CPU down, then releasing and allowing it to heat up.
Finally, if you really still don't believe, then explain how the reported "cpu temp" is always higher than the reported "core temps" at idle? After all, the "cpu temp" is from a sensor between the cores and should therefore be cooler than the core temps at idle. Also, do you think that idle core temps could be ~20C when the room is the same temp or warmer? Of course not! Core temps can't possibly be that cool.
By the way, the RightMark CPU Clock Utility is a killer app. It allows you to adjust how Speedstep operates, and also allows you to adjust voltages. However, these features aren't usable in an overclocked desktop system (highest settable voltage with my chip in the app is only 1.212, which it also thinks I'm running with). But if you've got a notebook, by all means install this app there as well. My Pentium-M runs fine at the x6 and x8 multipliers with just 0.700v and only requires 1.020v at 1.6ghz. That translates into a significant battery life extension.
Anyway, the E4300 is the Allendale core, which is different from the previous C2D chips based on the Conroe core. From what we can see here, Allendale seems to be running hotter than it's predecessor.
Oh, and Maz, I accept your apology in advance.
