[TR] One last Radiator question

[terryrs at comcast.net]

I think the upshot of the recent thoughts comparing aluminum to copper radiators is that it is about a wash.  There are more fins in the aluminum radiator to make up for the poorer surface heat exchange.  Then someone else made the point that it would take more power to push the air through the fins.  

Question:  if adopting an aluminum radiator, would the stock fan system be sufficient to suck the air through the radiator at idle, or would an electric fan conversion be pretty much necessary?  ...Am wondering if the move of Macks, Petes and the like to aluminum might be cojoined to a simultaneous move to electric fans as an enabler?

Thoughts?
