I have had the graphics card for a year and it has never given me problems, but for a couple of months it has overheated in an exaggerated way, even turning off the computer. I do not know what the cause may be, I have changed the thermal compound but it has changed little (I have used artic mx-4), i also did a clean driver intalation using ddu and the computer is clean. Thanks for your help.
Too high seasonal temperatures may cause the temperature problem you are experiencing to become apparent. If thermal paste replacement does not solve the problem, I recommend that you keep the cover of your PC case open and operate it in a place where your PC case can get comfortable air.
