I have an asus formula x and it has three EXT_FANs, which I'm not sure what it is and if you purchase whatever gets there separately

Thank you in advance

Not sure exactly what mobo you have. The website for their Maximus X Formula mobo, p.1-19, says it has three CHA_FANn headers for case fans, ONE header called EXT_FAN, and several others for specific uses. The EXT_FAN header is NOT for use with any standard fan directly. Instead, it is a place to plug in an extra-cost accessory you get only by ordering. That is a circuit board with additional fan headers you can use through the mobo for more fans. BUT, to use four fans with your existing mobo and not require that added board, all you need is a single SPLITTER that will allow you to connect two of those fans to a single CHA_FAN header.

Well this is why I'm confused, the fans of the case are already hooked to the case's fan controls panel (case is phantom 820) ... Do I put them on the MB or keep them on the case?

PS: MB only has 3 EXT_FANs while the case has 4 fans
