I have an old NZXT h710i case and I'm doing a rebuild. To simplify things I wanted to pull out the NZXT Smart Device V2 and plug the NZXT case LEDs and fans directly into the new motherboard. It looks like the fans have three wires and so I'm assuming that those are the DC mode variety. What about the LEDs? Does anyone know if they are they 12v or 5v? I was wondering which plug on the motherboard I should use.
