Which is entirely how I construed the discussion to be. My comment was only 
that the OEM fan being fixed pitch, would only work fully at a fairly low 
engine speed. As we all know, it operates across the whole engine speed 
spectrum and therefore will scoop more air at certain speeds than others. 
Same applies for an electric fan as blade pitch is also fixed but running 
speed is constant

What was my *attitude*? Was I offensive? Please enlighten me.

I'd agree in principle but we're all occasionally plagued with electrical 
gremlins and I'm no exception. I just prefer a calibrated gauge operated by 
a capillary tube rather than an electric version.

Well, I was just copying factory build procedures. Cars destined for hot 
climates (within the tropics) had larger radiators (more coolant, more 
tubes, more fins) higher output water pumps and cooler 'stats.' So perhaps 
the alternative smaller rads/hotter stats were *inadequate* for the tropics 
but not for cooler climates?

In my case, it's not the size of the motor(s) but the fan itself. I can't 
fit a large Kenlowe unit as a pusher but I can fit two smaller units - and 
even one might be enough.

More coolant, more tubes, more fins but using current radiator manufacturing 
materials and techniques in preference to those of the 1960's. That's how we 
use the inferred term *state of the art* in the UK. I thought that was how 
it would be interpreted elsewhere. Obviously I was mistaken.
