"During the overclocking phase of this review it is interesting to note that the chipset heatsink was frightfully hot to the touch, and more than likely detrimental to the overall performance of the motherboard. "
when nVidia went from having separate nb & sb on 6xxx IGP to an all in one on 7xxx I'm sure that it became cheaper for them to produce (& hence probably more profitable for them) but it definitely resulted in increased chipset temps.
I've got abit's I-N73HD based on the same chipset here to play with once I acquire a spare CPU.
