PC fan power supply, anyone got a how to?

hey guys, i'm having a few troubles controlling temperature. i would like any information or help anyone could give me about fixing up some pc fans, i'm not an electrician and have no idea how to even power them. And also, what level of ventilation would i need for a 4 cubic feet box?

at the moment i am about to receive delivery of a 4" desktop fan, i am aware this will not be enough but i think pc fans is the way to go, unfortunately i need some guidance!!

thanks for reading, and any response

You can cut the plug off of your PC fan. Then cut the plug off of a cell phone charger. Connect the two together and there you have it

I wouldnt recommend any shoddy wiring.

Do things right, get some good grounded wiring and UL listed appliances.

hm, ok thanks guys. anyone got any tips on what size/strength fan i'm gonna need here?

Just go to Best Buy and get one... WTF?
