If you have no overheating issues the fan noises may be from the fan shroud. make sure its there and secure. bent fan ???
where you live if its very hot most times electric fans can fail. the fan you have is more reliable.
the correct fan motors use high amps . you would need a large alternator , 30amps or more.
make sure the radiator/condenser external is clean and free from restrictions .
