I want to make a desk fan using a 4-pin computer fan. Are there cables that could mate 4-pin to USB or AC?

I have found some links to solder usb to 4-pin, I just don't think it's worth it if I have to do that.

Answer:
Case fans are 12V, USB provides 5V, so you can't just wire up a computer fan to a USB port, if it does work at all it will not spin fast enough to make much of a breeze
Computer case fans use DC power, if you try plugging one into AC power you will probably start a fire, but you can get an AC to DC converter, they have ones that convert the power from your wall socket to 12V DC that will work, they are usually in the car and boat accessories section, they are meant for using equipment that only plugs into car or boat power outlets which are 12V.
In the four pins to the DC,(12v), computer fan there are:
1.12volts-DC
2.Ground
3.Ground
4. Sensor
Do NOT connect this to AC! Fans are 12vdc!
