Blowers blow and fans suck.
Ive got both on all my HB amplifers and, as near as I can tell, they
work well.
Since this subject has gotten way off topic, I'd like to mention my
latest use of a big, DC electric fan: On a QRO car.
The installation of a 502 CID, fuel injected, 600 HP, 600 foot pounds of
torque engine in my 2800 pound 1968 Corvette roadster resulted in
considerable over-heating. I removed the engine-driven fan, and
installed a large multi-blade electric fan on the in side of the
radiator.
Thermostatically controlled, it comes on at 160 degrees and keeps the
engine below 200 degrees.
This car/engine/fan is sort of like Rich's 8171 amplifier.
