Not too happy with my fans.....

The newer electric fans with the curved blades move more are than the older straight pitch blades. I'm in Texas also, & temps at the strip can be brutal. I changed my old straight pitched blade fan to one of the newer curved blade fan & it did make a difference in cooling my car down on the return road & in between rounds. I'm not saying that this will solve the problem on a street car, I'm just speaking of my experience. If I had a street car, I would run a 7 blade factory fan with a thermostatic clutch, but that's just my opinion.
