Hello I have bought Alphacool Eiswolf 2 AIO - 360mm RTX 3080/3090 Gaming/Eagle with Backplate around 3 years ago and since some time when I'm playing I get gpu overheat and crash. I checked pump in bios and it has 3000 rmps. I noticed that my radiotor is not hot at all when the crash happens. Sometimes it works fine for few hours and when I touch it with hand i can feel the heat from radiator but when I notice fps drop and if I dont quit game fast enough I get crash. (radiator is cool then). Also I don't get crashes on idle or anything like that.
