[SOLVED] AIO working, but no lighting.

[LordGio]

I have a Coolermaster ML240L V2 RGB plugged into the JRGB header on my B550 Tomahawk, but none of the lights are on. It's my new second pc and my first time using an AIO.

it's likely controllable from the MSI mystic light sync software

I had an epiphany while I was out: When I was building, I had a concern about the fact that the rgb header is asymetrical. But the cable for the AIO didn't have an indicator for the orientation like the other cables was.

Long story short, I simply had the cable upside down. Once I rotated it, it started working fine! Hopefully others will see this post if they haven't tried it
