i am getting an 870e ASUS crosshair or strix motherboard for my new 9800x3d they only have ARGB 5v headers. I want to use the 14 LED case fans that i have now on my two rads on my 5900x build(480mm and 360mm in push/pull) but they are old style 12v 4 pin RGB but the new mobo dont have both headers like my x570 crosshair has. I really dont want to buy 14 new fans just for lighting.... can someone suggest a solution, thanks
