Because you say "Speeds 2 and 3" I'll asume your talking about the radiator fan,
I think your brain flipped a bit..you were thinking blower motor fan and typed radiator fan.
I replaced mine hoping for more air and it didn't improve much. Sometimes there are leaves and other crap embedded in the evaporator that make the fan work harder resulting in the noise. While the fan is out try to clean the evaporator. You can get a flexible vacuum cleaner hose in the hole but be careful the evaporator is made out of very thin metal. If you poke a hole in it, your ac will vent refrigerant all over the place, (assuming there is any in there).
