Note the motherboard temperature. With the IHS on the processor, the motherboard temperature was 25°C, but here, without the IHS, the motherboard reports its temperature to be 27°C. Why the difference? My best guess is that since the processor runs cooler without the IHS, the heat it pumps out is transferred faster to the heatsink than when the IHS is present.
Thus, the heatsink would become slightly hotter without the IHS on the processor, and thus the air exiting the fins of the heatsink would be slightly warmer. This warmer air would, in term, raise the temperature of the motherboard, since it blows overtop of it after leaving the fins of the heatsink.

from the article you linked, BB2k.
it makes me doubt the entire results abtained.
