Im sure its possible to bend stuff around but I wouldnt do it untill your sure it aint supposed to be that way.

I'm 99.999 percent sure they are all supposed to have the same pitch. Can you bend them back? Sure. Is that the best thing to do? I think not. That fan is damaged and is no longer what you'd call, "safe." Unless you like the idea of rebent fan blades breaking off and flying around under the hood or up into your face or through your radiator or... Get the picture? Time for a new one, IMHO.

Hi Rick!

The fan does not have the same Pitch for all blades from factory!
Please don´t bend them back cause at high speeds the blades then begin to swing.
Therefore the blades are not at the same degree distance on the turning circle.

Badest thing to happen is that the swinging of the blades will cause a crack when they are evenly distributed and then the blade looks through the hood.
This happened to a friend of mine - not the best event, you bet! Blade cut through the hood and went out!!!!:eek: :eek: :eek:

This is an aerodynamical phenomenom which I can´t describe out of my head right now, if you wish to have more proven evidence I need to look in the engineering books. :crazy:

Is this a stock fan?

I've never really noticed the pitch of the blades, but given that the blades are not even spaced out equally, it wouldn't suprise me at all if the pitch was different.

The fan blades are not spaced evenly so that they break up a tendency to "beat" or resonate at a particular frequency. I never noticed any difference in pitch but it could be that they are different for the same reason.
