120mm vs 140mm

Doh, you beat me to it.
For heat sinks and rads, 120mm is king right now.. due to the dead spot the center winding motor takes up.. and there aren't many 140mm fans available with good static pressure (or, just in general)
As for case fans, 200mm are the "best" right now, as they can move even slower and push more air. Unfortunately the size thing isn't a standard - as each case manufacturer has random widths and screw hole locations for their 200mm fans.

Yeah I found that one out almost the hard way once. Thankfully I read a few product reviews that actually contained the correct information and helped me from a poor purchase.

Yeah the hub will create a dead spot, but its not really a game changing difference if the radiator itself is enlarged to fit the 140mm anyways. I would imagine the surface area lost/gained by this would be the same.

As for the Static Pressure, yes thats pretty much the failing I see right now is the low RPM numbers are equating to lower H20mm numbers as well.
Time will tell what will happen.
