Can you buy a quiet fan for amp?

I have a qsc amp powering a larger vmps sub. This amp has a loud fan that is constantly on. Can I change this fan to a quiet one and if so where can I get one? Could I just take this fan out and not replace it, or should I just get another amp. We just built a house and went to great lengths to get a quiet room. You should have seen my contractor's face when he heard that amp come on.
