I know this won't answer your question directly but noise is a factor of
turbulence in less-than-optimal fan design. I've found that you can
cheat by getting a high output fan (big) and reduce its speed (and
noise) by lowering the voltage to it. small fans can't push a lot of
air without creating a lot of noise.
