Good Afternoon Toms Hardware community!

I have an issue I hope someone can help me with. I have recently upgraded my computer with some new fans, graphics card, mobo, and processor. I purchased 3 fans that say they are compatible with Asus Aura, and a Asus Prime x570 mobo that offers Asus Aura compatibility. I have hooked up the fans to the white 4-pin RGB headers on the mobo, the fans light up and change colour which leads me to believe the ports are working. All three fans do the same thing so I do not think the problem is with a faulty fan or connector. I have a Corsair 1000W PSU. The bios shows all fans running but one, which is very strange I expected at least 2 fans to show up as 0 rpm (I have the third temporarily unplugged while I troubleshoot these fans sans RGB splitter).

Any advice THC? (toms hardware community... not tetrahydrocannabinol lol)

I think I may have just figured it out, the PWM fans have two cables the 3-pin and 4-pin, I thought the 3-pin was like legacy support in case you wanted to use the fans in a non PWM/RGB mobo but now I'm thinking you need to use them both simultaneously... I'll hook that all up later tonight and report back.

Lights (RGB 4 pin) is one cable only for lights, there should be another one for fan motor. Both need to be connected to appropriate headers on the MB.
Give me a link to those fans.
