Hello. I am installing an EK water block onto a Gigabyte Aorus 1080ti Extreme. I have been told that I can not use the stock back plate with the EK water block. Though I do not understand why because they do not seem to interact with one another. I was told, however, that I did not have to use a back plate if I did not choose to purchase an EK back plate. Can I leave the back plate off or will it cause heating issues, since the stock back plate did provide thermal pads and the copper heat sink. Thanks for the future replies.
