I have found from personal experience that AC fans are louder than DC fans plus you canot control the speed, its full speed or nothing.

You can control the speed of AC Fans. Buy a dimmer switch. Thats what I did on my last tank.

cp fans are cheap and have high output and use low voltage i hooked mine to a cheap 12vdc power pack

I went with the 12V only adapter and wished I hadn't . . . now I can't make the fan quieter.

You should still be able to regulate the voltage, with a rheostat or even a 120V dimmer - the 120V dimmer can take up to 120V, so 12V would be cake

Thanks for the advice aprosody! I am by no means an electrician. I know a ton about building computers and picking components, but not much about electrical wiring.

The only reason I knew that answer was because I just asked the engineers at my work the same question last week.
