Question Spectrum RGB Fans flickering when playing games ?

[KKnows93]

Alphasync prebuilt with an Asus Prime B550M-K Motherboard, 2x 8GB DDR4 Ram, Asus Mini OC 3060ti, Corsair CW650 power supply, Ryzen 7 3700x CPU.

Spectrum RGB fans are flickering when playing games, from what I can tell is that they are connected via a fan hub at the back of my pc, not sure if they're connected to my mobo.

This was happening before and after undervolting my GPU as I suspected it to be a voltage problem but it still persists.

Any ideas what this could be and how to fix?
