As far as powering the 12 volt computer fans, the only imp[ortant wires are the red(positive) and Black(negative). If you are looking for an AC supply to plug into the wall, go to a second hand store and look in the used electronics, they usually have dozens of ac adapters. Look for one that says 12v 1000ma. This is enough power to easily power 4 12 volt computer case fans. You can get them out of computer cases people throw away. Just twist all the reds together, and all the blacks together, and strip back a bit from the connector of the ac adapter, and try the wires one way and then the other. The fans will only run connected one way. Bam problem solved.🌫 You have no danger of getting shocked at 12v 100ma.
