I have the Phanteks p400S, and it has a 3 speed fan controller on the front panel with a 3 way cable to connect 3 fans to it, when I use the 3 speed fan button I don't notice any difference in speed. So i'm not sure if I need a phanteks fan hub thing (sold separately) or im doin something wrong. From what I understand If wanted to control the fan speed I don't connect it to the mobo. the mobo im using is a Asus Strix Z270F.
any info is appreciated thanks!
