I recently ordered some Uphere fans that came with a fan hub. The fan hub come with 2 connectors for the Mobo, one labeled PWM and one labeled Mobo sync. I have found a port for the PWM connector. But cant find ome for the Mobo sync connector. It has 2 holes, then a gap, then one more. I have a Asus Prime X470 Mobo. Pleas ehelp!
