Why not use a fan better suited to watercooling - if one exists?
More airflow = more noise.. but as much pressure as you want, not much niose?
What if a over rated (in torque) motor was used, but with a resonably low rpm (for a fan).
Its the airflow and bearings that seems to make all of the niose, not the motor?
The motor wouldnt slow down much with restriction.. giving the same airflow but capable of several times more restriction.. = better cooling..?
And fans are cheaper than rads (I think!).
What about blower style fans instead of axial?
Or am I compleatly wrong about current fans not being perfect?
Also, is there any link between fan thickness and presure ability?

Need to remember Hoot, we're talking about the near-silence obsessed here. Fans that you can barely hear (or not hear at all) in a quiet room, with everything else turned off, in the middle of the night.

Ive got a 172mm nidec (TA600DC A33142-10), seems to have bearing noise,not sure which type of bearing but any idea to quieten it a bit?
