Agreed, there are other factors involved too, but the Nippon Denso rad even at 24FPI does not appear to be that restrictive to air-flow for axial fans.

Also, even though there may be less air-flow, it's all about balancing off the improved convection from greater surface area due to a higher fin density vs a slightly lower flow rate from increase back-pressure. I don't see radiators in this respect being much different from water-blocks.
