Adding an old fan to an old PC
I found a fan around the house. and i want to add it to my case. heres my question. You that wire coming out of the PSU that you attach to the back of a n optical drive it has like 4 holes, its like 1 yellow, 2 black, and 1 red. On my psu it has 1 head that goes into a cd drive and 1 more head coming out of the first head that you can plug into another cd drive. Now this fan has the exact same type of plug. its 4 holes yellow, 2xblack, 1 red. and it also has another plug coming out of the second, im guessing to replace the one its taking up? so if i plug the other CD head from the PSU to the fan, will somethin bad happen? and if its bad will it affect the PSU, or computer, or just the fan, if it breaks the fan i dun give a s***. PLZ help.
