Radeon RX580 8GB overheating. When I launch certain games (Dead by Daylight, Black Desert Online, Ring of Elysium, and many more) even when Im just in ingame lobby and not in a match my GPU starts to heat up and usually reaches up to 79C. I have deleted the Adrenalin software and am just running default drivers, have also tried to manually disable vsync in many games but it doesnt really help (a lot of forums I checked have said that vsync is at fault). Also tried using afterburner but its the same thing the only thing that goes up is the temperature.
