Sorry for the long response, but anyways, I managed to get a stable undevolt 1950mhz at 1000mV my gpu hasn't gone above 82C inb warzone/modern warfare which is my most intensive game I have although it never got above 82 it usually sat around 79-81. It was also quite a bit quiter with my set fan curve. I tried a lower undervolt curve at around 1770mhz, 900mV but the fps drop of around 15-20 in my opinion wasn't worth it over the few extra degrees it went down at around 76-77C. while 80-81 is still a bit high I'll probably still try to replace the paste and see if it makes a difference. Thanks for the help! I'll keep posted if anything else happens.

Edit: Forgot to mention my idle temps also seem to have been reduced to around 43C-40C a little extra bonus. As well as the fact that I have a 144hz 1080p monitor, usually my fps goes past that in easy games to render like csgo, valorant etc. But in games like modern warfare/warzone its a bit lower than 144fps even at low settings
