Note that on the NPD website that the 6 blade fan is not warranted for use over 4000 rpm. They are absolutely correct. I replaced the original 4 blade fan on my car with the clutch fan setup earlier this summer and it only lasted until the next autocross where I developed a high rpm vibration and it made quick work of destroying my water pump. Not for high rpm applications! I went back to the original 4 blade fan.
I wonder if the 6 blade fan could be balanced for my 6400 rpm redline?
