I've seen several references to using fans on this forum but have never seen evidence of anyone actually doing it.

These are 2 of the 4 fans I'm using. They are Spal fans, 5.2" diameter if I recall correctly, 2 push and 2 pull (obviously, the pushers are inside the shroud). The controller is a Spal PWM 2 speed controller. The set points are end user adjustable/programmable. I tapped into the IAT sensor for an input. I have the low point set for ~100 degrees IAT (otherwise, sitting in the sun, well, anyway...) and the high point is not far above that, about 120 degrees. The switch up top turns the fans off - they are noisy and not always necessary/welcome.
I do not have any data logs to support my conclusion that they work. They do. It can and will be improved when I have full use of my tattered right arm again (titanium rocks!). The fans move a reasonable amount of air, and dropped IAT's about 30-40 degrees at the track.
My total expenditure was under $200 (purchased all from Ebay gradually over the winter) and they were very, very easy to install. 2 beers on a 6 beer scale.
If you're confused by the white stuff - that is dust. She hasn't been driven in about 2 months...
