Alright i am building a new case and i found some nice fans for it they are 190cfm 90mm indusrial fans for an old machine of some sort and they say 120v and 4a so i am wondering if anyone can explain how i can get these to work in my computer i am using an old AT power supply to power the fans so i think it is 12v. So far i am thinking that they will need to be plauged directly to the wall socket but im not sure of the electric things. So my question is how would you guys do this.
