I purchased a Bitspower Logan VGA waterblock for the MSI RTX 2080. The 3-pin LED connector doesn’t seem to fit anywhere on the motherboard. After scanning the RQ code on the box and entering the product code there’s a diagram saying the connector needs to go to the DRGB pin on the motherboard. But I couldn’t find any pins marked DRGB. The only place on the motherboard that matches the diagram is labeled SPDIF_O and the 3 pins are just a little too thick to fit in the connector of the waterblock. The motherboard is a Gigabyte Z390.
Do I need some sort of adapter? Please advise?
