That little? Then I guess that I used enough. The instructions say something about 4mm circle; I think I put very slightly less. It doesn't say anything about spreading it, though, and neither did a couple of demo videos I watched on Youtube. I find it hard to believe that it would be squeezed all over --- but then, perhaps if I had inserted a finger before tightening the screws, I might have a different idea!
The installation was undramatic. Having removed all the mb connections, I started to wonder if I could fit it with the mb in the case. The backplate is not captive; if all four screws were undone, it would just fall off, but the stock plastic bracket is fairly flexible, and the screws are long enough to permit loosening them enough and, with a little gentle twisting of the plastic, to get the Noctua brackets screwed in, one end at a time, while the remaining screws hold the plate. Noctua's instruction to "tighten the screws until they stop," leaves no room to worry about overtightening.
Lining up in-case was probably harder, but not that hard.
Of the remaining grease, I'll start with three stripes on each arm and three on the forehead. If this works, I'll apply more elsewhere. Anything to reduce the summer AC bills! :lol:
(Actually, I think vibuti (sp?) does have some cooling effect!)
