I was going to mention that but my post was overly long even without it.

The TR7's had this device and they have been known to fail causing a horrible 
noise like the engine was coming apart.

But they were very common on domestic products and still used on some trucks.

Another option is the flex fan.  This is a fan with flexible blades that will 
fold towards flat as the speed and fan loading increases.  These are about as 
noisy as fixed fans.
