And why do "they" use fans with 6 to 9 blades in modern cars ?
And if you use a 2 blade, why dont you use a shrout to make
a better air-flow and reduce aerodynamic losses?
Have a look into your modern car.

As i installed a new HD-radiator, i (being in fear) as well switched to a
6 blade plastic
(ja - its ugly) from the well known vendors. I cant understand why its so much smaller in diameter
For sure this will reduce airflow (knowing this, i wouldnt have bought it).
Summary:
Using the new radiator it feels as if i wouldnt need any fan at all.
