I have an NH U9s cooling a Ryzen 5 5600X on a Gigabyte Aorus B550I. With the default installation kit, I can only mount the cooler in horizontal mode. I searched and found that I have to get the NM-AM4-UxS kit to mount U9s in vertical mode. I searched images to find that the two small brackets are named NM-AMB6. Now I have NM-AMB8 from Noctua NH-D15, I wanted to ask if is it possible to use the NM-AMB8 to mount the U9s in a vertical orientation. is it compatible?
