Though counter-rotating fans may have certain applications they excel in... I would expect a centrifugal blower to punish them for their incompetence. If you are looking for performance against backpressure - a blower with respectable diameter will far outperform anything some form of axial fan can muster.
Of course, space and looks is often a governing factor for you kids who stick all those cathodes and toys in your box, so a counter-rotating fan may be a good compromise for some.
I thought SSS or Brian did an article on counter-rotating fans with a Swiftech NB heatsink? Might find an article at OC if you bounce google.
