This takes the noise level down from "jet taking off" to "most normal PCs" on a Monoprice Mini Delta.On mine, I had to reverse the wires, but that took less than a minute. After that, it was plug and play.Much, much quieter than stock. I don't know if there's a CFM difference, but I'm betting that as long as the mainboard has some sort of cooling, it'll do just fine.See full review
