Why are the blades of car radiator fans unevenly spaced?

처리 내용

It isn't something restricted to old vehicles; my Lumina has fans like this, though not as irregular as the picture shown in the question. As far as I can recall, the chief reason cited for this by the manufacturer is noise reduction . You'll notice the additional weight on some of the blades to ensure that rotational balance is maintained despite the asymmetry.
