Computer Fan Wiring Help

Whats up guys I got a small stealth grow box completely set with my lights and everything ready except the cooling system. I want to order two of these fans online for intake and exhaust: http://www.google.com/products/catalog?client=safari&rls=en&q=computer+fan&oe=UTF-8&um=1&ie=UTF-8&cid=5668996075972651769&sa=X&ei=_fTBTYW0DYS3tgfw_qWxBQ&ved=0CH4Q8gIwBA#

This may be a very stupid question but help me out here, how do I wire that fan to an outlet? And what parts do I need besides the fan? If anybody can help I'd be much appreciative I'm a beginner with the electrical stuff.

you need a 12vdc transformer. just a cheapo wallwart will be fine as long as it puts out enough amperes to power your fans.

you could also use a computer power supply, they already have that connection too. Keep it out of your box though they tend to get hot.

OR you could wire it free...... ALL you need is an old phone charger or any kind of charger for that matter. Cut the two wires at the end of the charger where it plugs into whatever it charges connect one to one wire on the fan and the other to the other wire on the fan. Depending on the size of the charger, the average charger will power 4 of them fans without any trouble at all. Its simple and you dont have to be to carefull about wiring them together, you wont get shocked by touching them or anything. Hope this helped.

like said above
Parts:
fan
razor
electrical tape
time
use a 12v dc adaptor to power dc fans ( ac power to power ac fan)

and if you are using fans that look like this..... then you can splice power to the red and yellow connection and then plug any extra fan into it. hope this makes sense just ask if yup need some clarification

actually you want to use the yellow and black wires for a 12v fan. the black is ground, the yellow is +12vdc and the red is +5vdc

you're kinda right. check my above post mentioning the wallwart. it cannot be "any charger", as it needs to be powerful enough to supply the fans with the amperage they require.

Oh man, I'm glad you posted this. I neeeeed to learn how to do this too, but I'm a real noob when it comes to electrical wiring and circuitry. I wish there was a youtube video on how to do this

black & red are the wires to use -yellow sends a signal to the PC motherboard to tell it how fast the fan is spinning. here is more details

Good to know
lol though it does work wired like so i have 5 fans hooked in
thats what i did with out know what the yellow wire's use was but shit it works..Glad to know what its for... i start my a+ soon

electrical tape sucks... buy some wire nuts.. very cheap keeps this easier.. and if you want to replace fan its much easier. and its not just amp because a 12 v .25amp fan wont run on 5 v .25 amp supply its best to ge a power supply that actually has more amperage than needed for one fan so you can connect more to same power supply.

remember when runing in series amps will be same volts will be divided. run in parallel volts will be same amps will be divided. so IE my comp fans run on 12v .25amp power suplly I have a power supply that is 12v .5 amps because they need 12v .25amp each.. and if you want to further reduce currrent (amp) because you have not used all amps on circuit add a resistor so fan is not over amped...

just some food for thought...

i believe the yellow wire is actually so you can connect it to a fan speed controller.
