You can rebuild your old clutch fan . The roar of the flex fan is obnoxiousness aside from the fact that they are dangerous on a

hi reving engine.

Just curious...anyone here ever have a flex fan disintegrate or personally know someone who was injured by one? I'm not advocating for flex fans, but it seems that there's a great deal of second hand information about them and little first hand experience. The term "Urban Legend" comes to mind.

As far as being more dangerous than the factory fan, I have first hand experience with my factory fan augering through my radiator that leads me to believe it wasn't too safe, either.

That and the fact that flex fans, or at least the one I had, state in the instructions what the clearance between the fan and the radiator shoud be. I'm thinking that if one flexed to the point that it damaged the radiator, those instructions weren't followed. As far as sticking your hand into one...well I've never done that with any type of automotive (or other) fan. My brother and I ran flex fans on other vehicles we owned back in the day and never had any of the problems mentioned above.

Dennis, yes, a flex fan ate my Mustang's radiator! It started out with a faint "ting........ ting......" and then all hell broke loose before I could pull off to the shoulder to investigate.

Steve, I can't remember how the fan was spaced, but I am an instruction-reader/follower sort of person.

I've had a Hayes flex fan on for many years...as you said, I've observed the flexing at high RPM and the blades don't seem to flex beyond the front plane of the fan. As far as extra noise, I've never heard anything usual.
