So I have a asus rog rtx 2070 advanced edition. And the second fan (middle) one doesn't spin at the same speed as the other two. Is it any thing wrong with it? Or is the middle fan always slower. All three fans are the same size so I don't there would be any difference. In GPU-Z when fans are at 100% the second one is at 1900 rpm and the first at 3300 rpm. help
