Radiator Fan Noise?

[Justin G. Wood]

Sounds like an extra vibration almost when the car is in the neighborhood of
about 2500-3000 RPMs, believe it's coming from the radiator fan. Checking
the fan I find no lose parts, the car isn't overheating, just an annoying
sound. Anyone have any ideas?

thanks very much,

Take the fan off and test drive without it. The car won't overheat
without the fan unless you get stuck in traffic.

Maybe that's how fast the electric fan turns and it has a slight imbalance
in the fan blades. When the engine's rpm's are in phase with the electric
fan, it starts shaking?

Just a guess.
