Question aRGB fan not in sync with others

Jul 13, 2020
I have 3 aRGB case fans installed (1 in back, 2 up top) and have them (along with the 2 for the aio cooler in the front) on a 5 way splitter coming from my motherboard. 4 of the fans are all in sync, but 1 constantly reverts to doing it's own thing. Sometimes it's synced with the other 4, but most of the time it isn't. It's the top fan near a heatsink and the cpu power plug on the motherboard. I have tried it out of the case and it works fine and I have also replaced it with the same brand/type fan.

Is there some sort of electronic interference that could be causing it?

Any help would be appreciated.
