I have a Gigabyte GA-K8NF-9 board which is similar to the chaintech board, all the pictures that I've ever seen of it on the net had an active heatsink on the chipset but the one I received has a passive heatsink.

It looks like the heatsink may be very minutely larger than the one Chaintech was using, I hope that it doesn't run hot for me =(

for testing the NF4 chipsets temperature is it possible to measure this from bios or is a thermal sensor required to be placed on the chipset? I'm still waiting for other hardware before I can setup the board but will try to look into this if possible (i dont have a thermal sensor :[ )

Way to go Xbit. Exposing product flaws and forcing manufacturers to correct them before they go retail is awesome.
