Both are inconsistently calibrated from CPU to CPU. Both, to my experience, under-report the die temperature to a moderate or even extreme degree. Phaestus uses the Athlon diode to success by bypassing any mobo "interference". His results are still specific to his particular CPU though and if he changed CPU, he would need to recalibrate his readings.
With the Athlon diode on one of my CPUs is that it seems largely immovable for moderate heat loads - with any voltage/speed up to 1.75v/2.2GHz resulting in the near exact same readings for pretty much anything, and it's only by really bumping the voltage, MHz, and running BurnK7, can I actually get it to budge by a significant amount, so yeah, not linear at all for that CPU - and it varies from CPU to CPU.
On my P4, I can get it to trip the CPU's automatic critical thermal shutdown (135C as per the calibrated internal non-user-visible diode), while the user-visible diode doesn't read much above 60C.
Sarcasm wasn't intended in the comment - it's just a reality.
Re: radiator "sweet spots". My theory on this is that it is caused by degenerate conditions occurring in the inlet/exchange tanks resulting in certain tubing sections of the radiator being "favored" over others.
