Message I actually looked up something to back me up,

It was found, in accordance with previous results from known literature, that alterations in blade spacing do not significantly alter the total SPL nor the cooling capacity of the alternator radial fan. However, significant dispersion of the sound power over several harmonics was found with irregular fan blade spacing, thus allowing for a reduction of the siren effect. This phenomenon was predicted theoretically and confirmed experimentally.
