3x2 cabinet best airflow?

[hayzeheven]

Bout to go to the store to get a cabinet to setup a few
cfls, I was wondering what the best method of airflow is in a cabinet when using cfls? I heard of a CPU fan or two in the top n drilling holes in the bottom to draw air up thru the bottom.. Does this work the best? If so how many holes n how big to drill, n how do I connect a CPU fan to a power source?

PC fans are quiet, but they don't move much air. I'd go with a cheap duct booster from home depot if I had it to do over again.
$30

Hey dude, if ur gonna use comp fans then I suggest more then one of them (the more and bigger, the merrier). Also if u use comp fans, dont use a cpu fan, those are usually only like 8 in fans.
The following link has instructions on how to use a psu with out a motherboard (did it a few weeks back, works very well!): http://aphnetworks.com/lounge/turn_on_psu_without_motherboard_the_paperclip_trick
Just remember that all the power thats going to the power supply that isn't used up is going to be turned into heat so have the power supply far away from your littles.

Ps: I do suggest just getting an exhaust fan tho just cuz its easier, more effective, doesn't create heat and it won't be a fire hazard in any way

ok i like the duct exaust green, thanks, pretyt sure u have helped me out with quite a bit, thanks for everything..

what about the holes in the bottom idea?

what you need is a variable voltage wall transformer

the forth and fifth ones down from the top are what you need,

the variable voltage gives you a built in speed controll. and no that wont hurt a dc motor.

If you are going to do holes in the bottom, just keep adding until you get the desired effect. Id say get two fans, 1 in, 1 out. Good luck with your grow!
