Dumb ass. For things this uneven there are thermal pastes with silver which are ten times better than the normal silicon oxide pastes. Besides that, you're only dealing with a few watts on a fairly large surface area. The clue here is that there is no metal slug on top of the IC package like there is with high thermal output chips like processors. No need to worry about exacting flatness, and it seems his adhoc methods won't produce that anyway. Why didn't he just use a bigger passive heatsink instead of a %$#&!@# fan? :x Using a fan on a northbridge is just retarded. The small, high RPM fans blow less air than a dragonfly.
I've spent way less time getting heatsinks for thermoelectric modules flat, and here it is important as you're dealing with 100+ watts on an area of about 2.5 in². I use plain old thermal grease and get good results(surface flatness is better than 0.001" by my estimate).
The guy didn't even do any before and after comparisons of his maximum FSB speed. His mod probably wouldn't have made much difference any way.
About the only positive thing he really accomplished, at least from Mercutio's point of view, is sanding off the nVidia logo.
