Ive never used a computer fan for a casing, but couldn't you just use an old power supply out of a older computer or somethign?

I have a ton.... haha
Revanche21 Reviewed by Revanche21 on . Computer Fans I've hooked up a computer fan to one of those cords for a phone charger. My question is if I want to hook up 3 or 4 fans for air circulation, is the recommendation to get 3 or 4 of those cords or is there a simpler method? Thanks Rating: 5
