is there any troubleshooting steps I can take before I call it defective. It is a brand new unit, straight out of the box.
Just because it's straight out of the box doesn't mean that there can't be a manufacturing defect.
Test the fan by itself and see if it's noisy.
You can always buy a new fan of the equivalent size and with the same connector. Heck, you can even buy two fans and use them in a push-pull configuration for even better cooling performance, if you have enough space for the second fan.
