I have an Asus Rog Strix b550f w/o WiFi (but did get an adapter) and ID Cooling XF-12025 ARGB trio fans. I just finished building one PC and the lights work but the fans are not turning. I’m not sure why... any help ?
Yeshave you plugged in both of the fans' aRGB and 4-pin PWM cables?
You should find TWO different sockets on EACH of the fans, and the set comes with TWO different cables. One is for the fan MOTORS, and contains a FOUR-hole female connector to plug into a single mobo SYS_FAN header and three male outputs to plug into the fans' motor sockets. The other (for the lights in the fan frames) has wider connectors: a THREE-hole female to plug into the included manual control/power cables OR to plug into your mobo ARGB header. For this last option you do NOT use the supplied controller boxand its power cable; you simply plug the 4-headed cable into the mobo header labelled "Aura Addressable Gen2 Header" - see label 10 on the diagram on p. 1-2 of your manual, and p. 1-15 - and then into each fan's lighting socket. It appears that these fans are of the newer 4-pin PWM mtotor type, so the SYS_FAN header you use shuld be configured in BIOS Setup to use the PWM Mode, and not Voltage Control (aka DC) Mode.
This is what I have connected. I’m building 2 so this is the other set out the box. In the one built I have the female end plugged into the 3 pin ADD GEN 2 header. The controller end of the other set of fan wires is plugged into the cable going into the PSU and SATA.
