Hey everyone, I bought a used Gigabyte 2080 Ti XTREME just a few days ago, and now I try to solve the mystery of a jet hiding in my PC case. Here are some screenshots of my "benchmark" results. Maybe someone can make sense of it, what the issue could be: https://imgur.com/a/jzt7vcz I just launched GTA 5, put it in 4K and mostly ultra settings, then started the prologue, and paused it at a demanding scene. In MSI Afterburner the lows are when the game is in the background, and the highs when it's focused. The same for HWiNFO, only the picture on the left was taken before launching the game. Now what I noticed: It takes only a few seconds for the GPU to go into some kind of "emergency mode" and ramp up the fans to 4000RPM. The specs say the max temperature for the card is 89C, and as far as I know cards usually start to throttle around 84C, so I don't get it why it tries so hard to keep temps below 79 degree. The clock speed fluctuates between 1500-1800, I guess this is how throttling works and how it deals with high temps. Another weird part is that the GPU usage peaks and sometimes stays on 100 percent, which drastically slows down the system, in the game and outside of it. I wonder if this is something normal, or if it could be avoided/limited somehow? On the other hand, on both charts I can see power limit appearing and being active, is that okay? Since on HWiNFO "performance limit - thermal" was never on, so how is this related to thermal throttling? I have an EVGA G3 750W 80+ Gold, for power delivery that probably should suffice. The last thing is that the core clock reaches 1950MHz, and mostly stays around the 1800s, which is new for me, since the specs only say a 1770MHz boost clock, but I assume this is okay My only guess (and what other threads I found kinda confirm) is that after a year the thermal compound for this specific model gives up and it's necessary to apply some new. So if somebody could confirm that what's happening is ACTUALLY thermal throttling, I might just go with it, and do it myself soon (no warranty on the card anyway). Any feedback would be appreciated! Cheers! TL;DR: Is my GPU thermal throttling? And should I try and reapply thermal paste on it?
