This feature was in the errata list until recently. And we have the reports of handwarm coolers for long. So I dont think it is that.
Could be the characteristics of SoI-manufactured chips are so that it consumes way less power in idle state that we are used to from bulk-silicon chips - pretty independent from supply voltage.
If so, to get your the warm or even hot it would require maybe ten minutes of full load operation. Which probably nobody did before touching the cooler. Could be as trivial as that, I dont know.

Edit: Your brillant analysis about sorting bins by current fits in here. And Elmers explanation as well: SoI is known for reducing leakage significantly, and by means of that static current.

Edit2: One step ahead: SoI should make great notebook chips then although max power consumption is high. OTOH, the benefit of PowerNow! (or Cool'n'Quiet) is much less than it was for K7.
Anyway, i understand PowerNow! sells, so its ok to keep it.
