I like the DC fans because you can vary the voltage to get different speeds, as already mentioned. This is nice if you've got more fan than you need, since you can just throw a 9v transformer on a 12v fan for instance.

Or to get even more advanced, put a termistor on it and walla, you have a temperature-controlled fan that will blow harder or softer depending on the temperature in your hood.
