depends of the fans =D lol you just gave us the fan sise thats all ,what about the power? you need to make some basic maths there =)
aw sorry lol. uh thats all it says is 12v dc. not sure about rpm or anythin. this is the link to them. [Store link removed]

aw sorry bout the link thing i didnt know. im half way through makin a new vegative grow box and a flower box, the veg box is 2ft by 1 ft and 1.6 ft high. im thinkin of changing fans as im gettin a 200w cfl light in there and i was thinkin of getting 2x 140mm 800-1500rpm fans. i was thinkin if this wil be be plenty would it be ok for a flower box a little bigger, i havent thought of that just yet. And thanks for helpin me out. (y)
PC fans can be very deceptive. While they may look small they have alot of power behind them and especially if used in a grow box as small as yours will be a HUGE help. I am actually going to grow a plant in a few months inside of a PC :P The CPU as well as the motherboard inside of a computer gets very very hot as there is an insane amount of data being processed at once. If PC fans weren't really great at what they do, Your PC would probably have melted by now :twocents:
Ahh... go for the 120mm fans. Will be useful for small boxes. The 12V ac-dc converter goes for 17USD on amazon.
ive made a new grow box as of today lol. it measures at 18.1/2" by 17 1/2" and its 30" tall. would i need the 140mm for this or should i still use the 120mm? this box will be for auto strains and will be using just red spectrum in it. plannin on puttin a 200w ontop and 3 45w around the plants. thanks for the advice :D
