I have the Asus Prime X399-A motherboard and want to install a 980 Pro M.2 SSD into the vertical mount bracket. I need to know if there is a heatsink that will fit that, or does it need one? I also want to know if that can be used as the OS drive or is there less speed or to it? The reason for the last question is that I have liquid cooling and it would be a pain to remove the one under the main one, was going to switch that and make it a storage drive until the next cleaning of the liquid cooling. Thanks
