    Fans

    So I am finally getting the "built in" part of the tank completed...and yes I will post pics ASAP.

    I have a vent at the top of the wall that I want to mount a fan to blow the air out of (I already have 4 small ones blowing in) but I want it to draw the air out 24/7. So what I am wondering if anyone knows of a fan that will move a fair amount of air while being very quite? I know I could go to Princess Auto and pick up a dozen fans and try them to find a quite one but I would rather go spend more money and just buy a single "quite" fan.

    Thanks
    Rob

    I have a pair of these cooling 4 three foot VHO's on my office tank at work, and a pair cooling 4, four foot VHOs at home. Very quiet.

    I run a bunch from princess.. the trick is to get the biggest 12v fan with the slowest rpm. I then run them at 9v using some big resistances on a laptop powersupply. can't hear them with my ear a few inches away.. perfect.
    i'm in the process of adding a bunch more to directly cool down the T5HO.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    When you say the slowest RPM what range are you talking? How much air do they actually move?

    Yes, rpm (revolutions per minute). Or as many fans are labelled, cfm (cubic feet per minute).

    is there any advantage to using the 12V models?? i have a few 120V AC ( like the one in zookeepers link ) that are pretty quite, i doubt you would hear it through a hood.

    no real advantages from 12v to AC unless you factor if they ever found their way in the tank, 12v wouldn't zap you. but personal taste here, I found that all the 120v fans I have tried were too loud. DC is easily dimmed, AC fans are much harder and usually require special dimmers if they can support them.
