Desperate help with computer fan

Guys I need help asap !!! How do I wire up computer fans for venting can I just put it in a plug ???? Pls help quick 

there are diagrams on google

what ever you do, do not cut a random coord and connect it to the fans prongs lol. that will be bad.

You run a DC fan from an AC source. You can use a stripped cellphone charger to supply the AC power to a DC fan. Just make sure the volts on the charger are equal to the fan. You can run more than one fan on a charger if the total amps drawn by the fans does not exceed the amps supplied by the charger.

It's pretty easy to do in the realm of MJ electrical.

Do a web search.

You got 12V fans? You're going to need a "charger" that supplies 12V. Phone charger's work best with 5V fans.

Just remember to cross the red and blue wires and don't fuck yourself up. You can test the connection by touching the bare metal to your tongue.

I found it using the search engine: key words: wiring fan

Here's one I rigged up. I took an 120mm case fan and old Tracphone Motorola cell charger and connected them. The fan is 12v DC and the charger is 5v DC output So I don't have to worry about the fan getting too much juice and burning itself out. It's only two wires, so I believe it will spin the fan one way or the other depending on which way they are hooked up or not work at all. Another way to run a PC fan is to connect it to a an old working PC power supply. To turn on the power supply without it being connected to a motherboard take a paperclip and tap the green wire outlet to any black one to turn it on; VIDEO CLIP! (Be very careful doing this and don't shock the be-jesus out of yourself.) Here's some pics of my rig job, it had fancy blue leds which would have just eaten up some of that 5V so I snipped all the wires to the leds. =)

I save my old power supplies that are anywhere from 5v up output. A cordless drill charger is 12v typically.....I'm currently using a 6v to drive a 120mm fan in my dry box. Works great!
