While the NH-L9x65 is
much more compact than the typical CPU cooler, it isn't as small as many
others. The key benefit of coolers like the ITX30 and NH-L9i comes from their
height... I would not be able to fit the NH-L9x65 in to the Mini-ITX cases that
I use (Minibox M350), but the other two (as well as the Titan cooler) do fit.
If I had a system with just enough room for a 65mm cooler and demanded the best
cooling, the NH-L9x65 would be the choice among those tested. @ BigBruin
