Without calibration, NONE of the temps are good for anything other than a relative comparison (i.e., doing this made my temps go up/down by 2 degrees).

At any given temperature, a silicon diode is good for an accuracy of +/- 5C temperature measurement without calibration. It is possible to apply some mathematics to the problem and take a SWAG (Scientific Wild A$$ Guess) at what the calibration curve should look like, but without characterizing the diode, you are really just making a guess. It's entirely possible that either or both Hardware Monitor and SpeedFan are attempting to make guesses and guessing differently.
