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?
