RE: Electric radiator fan for alpine

I had a problem with my car heating up both in traffic and at speed. I
put a 4 core radiator in the car and then I was fine at speed, but not at
idle or in traffic. I then built a temporary shroud out of sheet metal
and riveted/taped it into place. After that I was fine even at idle in
100 degree heat. It may be that the 3 and 4 core radiators just don't
move enough air to cool them with the mechanical fans at idle. My fan is
about 1.5 inches from the radiator. I have removed the goofy shroud and
am going to try installing a spacer to move the fan within 0.5 inches (1
cm for those of you who use a rational system) to see if that doesn't fix
the problem.
What is the fan to radiator distance in people's cars that don't overheat
in 100 degree weather versus the distance in cars that do overheat? Is
there a correlation?
