It would be really good if they could fit all this into a standard 120mm or 140mm fan housing. That way you could the fans just about anywhere and still benefit.
I think I know what you're getting at - replace those 200mm+ fans that are used for case cooling with something a little more “petite” so you can get the same cooling & noise in a smaller case.
That said, what I'd want is that tech used on the sub-100mm fans. Especially the one that the old fella's got in his Shuttle PC. That 80mm one whines like a bored 5 year old on a rainy bank holiday. :(
Biggest problem I've got at the moment (with my HAF932 rig) is that one of the 120mil's has developed a intermittent rattle, smack it and the rattle goes away for a while. And the rig is so quiet that this is VERY noticable. Got to wonder if I've got a worn bearing - the fan concerned is the case exhaust for the cpu cooler so it's well used.
Both my current GPU (Radeon 7990) and the previous one (Geforce 460SOC) were pretty quiet - fan speeds have/had to exceed 50% of max to make a noticable noise and it was only at 60-75%+ that I'd call it noisy (as in “hoover like”).
