How to power system fan without motherboard

[Guest]

Hello,
Im wondering, i would like to link 2 extra fans together and power through the mains, they both are 12v. How can i power the fans. I tried using a normal 12v power cord which was for a ps2 lool but i got no power. I think i need to convert the mains power from ac to dc but im not 100%. I am new to technology. Sorry for my newbieness

so lemme get this straight you have 2 computer fans lets say 120mms just for the sake of it and u want to power them outside of yourcomputer not using a powersupply or a mobo correct?
