Electric fans?

[Stano]

Ok here is the results 332 mile round trip. I drilled quite a few 3/4 inch holes in a orderly fashion above and below my fans. I did notice a difference, not as much as I wanted to see but better none the less. At 65-70 mph it stayed in the 195 degree range during a heavy footed session it climbed to the 200 degree range but leveled off there. I am gonna put one of my new 160 degree thermostats in before long and we'll see what that gets me it will definately run cooler I think. I only had a 195 in it cause I had it and I was getting tired of messing with it and it was runnin that warm with the 160 and 180 thermostats in it. I think putting holes in the electric fan shrouds is beneficial to getting more airflow at highway speeds since the fans cannot freewheel that fast.
