no you should get a 12vdc that has about 800-1200mA output and get a computer fan speed controller,
but if the question is will it work but not preform optimally than the answer is yes. anything over 5v should trun the fan. Hell I had some that would turn at 3.3v. However the lower the voltage the lower the CFM.

I have never seen a pc computer supply with a circle plug normally they are rectangle either with 20pins or 24 pins
You have to join the green wire and the black wire right next to it so that it will be always on
Also you must have the fans already plugged in before you plug it in
There you all the 12vdc you need
i found a power supply like yours just laying around, with the circle end, its working with 5 12v computer fans so yeah it does work

exactly what type of power supply is this
I could probably find a schematic and tell you whats what
uhh i got it from my teachers trash pile. it was used for computers in some way or another. its 12v DC output so it is compatible with my fans. but here is a pic of what im talking about.
The black and red wires together are the fan wires. the 2 black wires are the adapter/power supply im using. if this works can you let me no if i will start a fire? im scared of doing it. please help this is the last step of my grow box.

=) ok i have to go to bed i have to get up early =( but if i cant try it now i ll try it 2marrow when im able to call the FD just incase teehee. so you are POSITIVE it will work one way or antoher? should i use like scotch tape to keep together i have no electrical tape.
that should be fine. twist the ends together like twist ties, then if the wires match, tape it up, other wise its a bitch to untape.

why not just skip the 12 volt power supply and just get the PC Fans that are rated for 120 volt at radio shack instead?

you can not cause a fire a computer fan will only work in one polarity, if you reverse it it acts like an open circuit. also one might have a white stripe running down it or it will have little white dots. but you will quickly realize whether or not you have it in the right polarity.
twist them and tape them it should be fine. If you are really concerned about fire you can do a couple of things like put the transformer in a pie tin with nothing over it, a baking dish would also work. dont worry heres the rub if anything would catch on fire it would be the fan now while fire will conduct electricity there isnt that much stuff to burn there so most likely it would burn itself out. I woulent worry about this. What i would worry about is the smell you are obviously in school, most likely living at home. you do realize that growing weed smells about 10x stronger dried cured weed.

ok thanks for the long response it helped alot captain. yes i no died/cured weed smells 10x stronger but that will not be a problem i will be curing everything in my attic where its cool and basically the smell will escape since everything isnt insulated. also ill be bagging it in my attic before bringing it down so i dont stink up my place =)
