at all. Have been most impressed with Phaestus's calibration work.
Meaning that the readings are peculiar to the CPU (and its diode) itself, and to a lesser extent the effect of the motherboard.
The 11.33x7.37mm (83.5mm^2) T'Bred B die, with the calculated ~75W heat load producing ~9-10C delta's resulting in calculated C/W's of around 0.12-0.13 seems to me to be a bit low, and has nothing at all to do with Phaestus's exemplary calibration work. Would personally feel more comfortable with derived C/W's of around the 0.20 mark given those dimensions. Even accounting for secondary heat paths, I am still grappling with accepting that the motherboard's secondary heat paths could be half as effective again as the waterblock is at removing heat from the CPU.
