Most AC fans of a given size will have a bigger motor than DC fans of the same size. That leaves less cross section for the air, therefore for the same air flow, air will have to move faster and be noisier. It is not a question of 12V versus 120V, its DC versus AC.

It isn't clear why you need to change to 12V fans.
Why not "modern" 120V fans?
