I wouldn't keep the fan inside a box for the reason that you stated, but Hudson listed three nice alternatives. My Vortex is hanging from flexible bungee cords, which is MUCH quieter than the metal hooks that were provided. Some people use speed controllers like potentiometers and rheostats to control the fan speed, but from what I've read, this can potentially be a fire hazard. The bungee cords work really well, so give that a shot if you're able to.
