I have a hadyen pusher fan that I installed after I had my rad recored as well
(I think I specified too dence a core for
the 4 blade fan to cope with). I've mounted it up high on the rad (with those
little plastic clips). Not only does it
minimise it's visibility that way I think it improves the airflow even when
it's not "on" as the normal air flow that
hits the bottom half of the fan causes the fan to spin and I think that draws
air thru the upper part of the rad which
normally doesn't get air.

I think you're correct, on a normal day with a new 180f thermostat that's where
the gauge sites.

I initially had a manual switch under the dash, but later I bought a therm
switch and what I did to calibrate it was let
the car idle with the fan off and let the temp get to what I considered to be
above normal but not yet "hot" (say 2/3rds
to the right) then turned then adjusted the switch until the fan shut it self
off when the gauge settled back down to
the centre. Then I stood back and made sure that cycle repeated itself on it's
own and that the fan was off most of the
time and only came on when needed. I'm not really sure what temperature that
equates to but it seems to do the trick
as the fan draws the temp down very quickly and is only on when the car's in
traffic.
