I am looking at a voltage mod for case fans that will allow your fans to run at 7v instead of 12v. Still moving a good volume of air but also being a little quieter.
What I don't understand is why can you add a 12v d/c line to a 5v d/c line and get 7v? Why can this happen with d/c without having to include a ground while in a/c trying to add two lines together would cause them to buck.
Why is this so between the two types of power?
