I did Stu's mod, and boy can you hear that fan roar. And it does a great job. Driving in 85F on a 70% humid day, and the car never got over one-needle width past 80C at 90MPH, and never over 90C when creeping through a 15-minute delay at 10-20 mph.

The only problem, it sucks down power; which means you have to give it more gas to get it moving the same way, and gas mileage suffers.

I think I'm going to really look into electric fan (s) with a thermostat. . .
