in my experiences pc style fans are alot louder and dont push air through as good.
i would recommend atleast getting a booster inline fan from home depot for about 25 bucks and a $5 wirable extention cord and your all setup. and its also easier to hook up your exhaust hose and lightproof.

good luck on it all
texas grass Reviewed by texas grass on . Computer fans for ventilation I was wondering if I could use computer fans for ventilation in a 4x6x6 clostet. I've seen some rated as high as 300cfm. My logic tells me "why not". So guys...why not? Rating: 5
