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.
Buy an ATX psu. Most ATX psu's still come with the older AT connections. :)
you sure they aren't AC (plug into the wall) fans? It should say AC or DC on the fan. Determining from that voltage alone, I'd say they're AC fans, so you plug them into the wall.
I have an Atx power supply i just am using an old AT to power the fans and i tried the wall and they work so i wil just use a seperate cord for them. They should push quite a bit of air as together they are around 400 cfm and when i turned them on they would nearly fly off the counter. Also i just found another big 120x36mm fan in a psu early today that i will be using it came out of a old computer some IBM i loved the case but it isnt ATX it has all kinds of old parts in it my favorite is the old hardrive it is probably 6 inches thick and a foot long and only 20 megs lol.
