How to wire a cpu fan?

I was just wondering what you guys wired up your computer fans to.. to make it work. thanks for the help

A video camera charger. Basically, just look on the plug of any Mobile phone charger, video charger, ect. and you will find the voltage; you want somewhere between 8v to 20v, that's just a ruff approximation, different PC fans have different voltage but there is a lot of lee way. My PC fan is supposed to be 12v, but I have it on a 8.5v adapter. Just cut of the end to expose the copper wire, and do the same to your PC fan, then twist em together its that easy.

word sounds good ill try that later

dude. i had the same problem. i am currently using an old phone charger but weirdly enough i found a 9v battery worked better.

if you guys can get your hands on a model train controller for cheap do that i had an old one and as of right now im running 4 cpu fans off of it in series and they run about 2-3 times faster than the one i have on a cell phone charger, it has a "throttle" so you can change how much power is going into them, which is how fast they are spining. it i sweet since other wise you would need a seperate circuit to plug in all the phone chargers

you can see the box looking thing that is gold and black hat what that is a model train controller

I just used an old cellphone charger. Its set up to my light timer, and its working amazingly.

Do you turn the fan off when you turn your lights off?

i keep my fans running 24 hours a day and my lights are on 20/4 scedule

a guy made a tutorials for this... and a pretty good one

you will need a 12v adapter and then hook the wires to the red and black wires, plug into plug socket and they should run full blast...

thanks used a cell phone charger and it worked perfect thanks.

im stumpeddd, i have a fan, and its wired to my charger, blcak to black, red to red, and it goes good for about a minute, then just stops?

Sounds like you're burning them up. Check the voltage on the DC converter. If it's higher than the voltage on the fan.............well, there's your problem. I use 6 to 8v chargers on the 12 volt fans. Run slower but forever.

it says input 110v output 5v

its that not enough

That certainly won't burn it up. What volt are the fans?
Try a higher voltage but less than the fans. Do the fans stop working permanently?

yeah like it runs perfect for aabout a minute.. then just stops

the fans are both 12 v.

I'm stumped! Maybe a bad charger?

both didnt work

get a new fan and a new charger...

a new fan too!


why 2 new fans.
