And after install the only difference I noted was the jet aircraft under the hood.

Yes, the jet airplane sound can be annoying, but it's a cheap fix and beats throwing the parts cannon at the car in the hopes of making it run cooler.

OP describes an issue that sounds like a lack of airflow at idle. If he's already tried a better fan clutch and fan, then he can try other things.

I like to do the simple things first. Usually works out ok.
