Old Air Cooling Fans on a big block?

It is the "Two fans on LO" where the fans get run in parallel at lower speed that is the key. It's much, much quieter that way.

This only works if you have two set points though.

That's right, and I believe the harness you get with the Old Air fan set isn't this type of setup.
