Do you have the fans set as a push or pull? I had mine set as a push on accident and it overheated and fried fuses all the time... Set it as a pull and my problem was fixed.

If your sure it was wired correctly you may have a bad fans.

Do the fans spin freely when spinning by hand? Is so move on, if not the fan motor is bad. Try connecting the fans right to a battery only to test, no relay. If they still sound funny, then it sounds like a DC motor brush or even fan bearing issue. If not rewire the fans, I suggest using the Perma--Cool fan relays. They are beefy and rated in RMS not peak current :bow down
