Question about Gigabyte Aorus Waterforce X 360

Hello Community I have installed the cooler according to the instructions. But now it is not displayed in the Aorus app and I somehow have the feeling that the CPU is not cooled correctly (when downloading Flight Simulator temperatures at 75-80 degrees). I can't imagine that these are the normal temperatures for such a cooling system. I have also downloaded the firmware from Aorus and loaded it onto the display (pump). However, still no success... Please, can someone help me? I am getting desperate... Thank you very much!
