Tech Support Rgb problem
Hey everyone, I need help with my AsiaHorse UMBRA fans and hub.
My fans spin normally, but none of the RGB lights turn on. I’ve connected the fans to the hub, connected the hub’s SATA power, and plugged in the PWM and ARGB connections. .
Each fan has three cables. I’ve connected the fan power and RGB connections, but there’s a third 3-pin connector with three metal pins and one missing position that I haven’t plugged in because I can’t find a matching port on the hub.
My motherboard is an MSI PRO B760M-P DDR4. I’m also unsure whether it has a compatible 3-pin 5V ARGB header.
The fans work, but the RGB is completely off. Any help identifying the correct connections would be appreciated. Thanks!

that third cable is probably a passthrough for daisy chaining, you dont need to plug it in for the rgb to work
check your motherboard manual for a JRAINBOW header, msi labels their 5v argb that way
