Is it a oem fan?
They tend to have blades at random spacing yo keep them quiet.
Aftermarket may have not done that.

Had a 74 Dart with AC 7 blade fixed fan on that one. Sounded like an airplane prop under the hood over 2000 rpm.
Had a factory shroud also.

Slip the belt off, and make sure it's coming from the fan area, and not the pump bearing.
I can't hear my fan over 2000, cuz the headers are starting to scream and the tires are already wailing. But I have a clutch on my 7-blader. lol.

I know I'm right....
Never knew that!~ I thought it was some sort of balancing act. Makes sense now as I remember a Chrysler air raid siren using a "chopper disk" to make the siren noise, looked like a turbine compressor blade. My only experience with a "throwing star" flex fan joke was the odd noise it made...right before I shut it down and pitched it in the trash.
Tires are the same way. Random tread sizes give a random sound rather than a fixed frequency
Don't know, came on car... Thanks
That is the rpm range mine is in 2000 to 2200. Thanks
Post a video or sound clip.
And a photo of the fan

Looks oem to me. I would take the belt off and run the engine up to the rpm you hear the noise and be sure it is not there, as AJ/FormS mentioned.
While the belt is off you can feel the wp for play / bearing noise. The other accessories as well.
Lastly, it could be you are not used to mechanical fans and the noise they make. If your cooling system is working well, maybe leave well enough alone.
