The diameter of a fan blade, driven via engine or electric motor , that is mounted to cool a radiator, is such that it's small diameter is small enough that it will not reach the speed of sound.

A blade tip reaching the speed of sound will lose performance. however we do not have to worry at the speeds we turn our cooling fans.
