Why is my bottom intake fan so loud

I just installed a bottom intake fan in my case, and it is loud as hell for some reason. By far the loudest component in my case, and I cannot really figure out why.

My case is on a tile floor and has feet on it, so the fan is sitting an inch and a half or so from the floor. When I lift the case off the ground it quiets a bit, but it's still loud. This has me ruling out vibration as the cause.

The only thing I can think of, which still doesn't make any sense, would be my cable management. Just above the fan there are some wires which are probably disturbing airflow to some degree (I'm going to fix this tonight).

Are bottom intake fans just generally louder than other fans?

There is no filter on the fan, and the case sits on a tile floor...Fan is about an inch and a half off the ground.
