I'm going to add 4 more case fans into my Nzxt Phantom 410, but idk alot about the fan controller. I know that it has 4 small molex connectors and 1 larger molex connector which connects to a sata cable for energy. I need to know if the smaller molex connectors connect into the wire that the case fan is internally connected to because I think that usually case fans connect to the motherboard. If the smaller molex connectors do connect into the case fan wire, does it require 4 pin or 3 pin so i can buy the fan
