AIO pump RGB stuck in a certain color

I’ve been noticing by for a little bit now that I can’t change the me color of my AIO pump. It’s always a shade of yellow, even when it’s set to rainbow the white or lighter colors are just a shade of yellow. Also there is a small red light in the bottom of one of my vengeance DRAM sticks. I think I saw somewhere that it’s because my motherboard js trying to control it. Any tips?
