Hello, so I have a Radeon RX 6600, and earlier this year I ran into an issue where I was playing Flight Simulator 2024, and I left the room for a little bit, and when I came back, my pc was off. Then, a couple of weeks later I noticed my computer was off when I woke up and wouldn't turn on. I took it to a repair place and they said that the MB had gone bad and replaced it with a new one. After I got the computer again, I decided to start checking the temps of everything, and I noticed that when I loaded the flight sim, my GPU hotspot temp would shoot up immediately and sometimes go as high 220-230F even when just in the menu but the GPU temp itself would only hover around 150F. From what I understand, this problem could be caused by the thermal paste no longer being effective; however I had only had the computer for about a year and a half and some things I have read say that it would take much longer for the paste to go bad. The other thing is that the issue really only seems to happen with the flight sim I play such as MSFS 20202/2024 and DCS world. I have played other fairly modern games like RDR 2, and I don’t seem to have this issue. I guess, before I go taking it apart and putting on new thermal paste, I just wanted to check if anything else might be causing the issue or anything else I should check. All the case fans seem to be working and I don’t see much dust inside either. I also tried undervolting the GPU as well as changing the fans so they come on earlier and run faster but that didn’t seem to make much difference.

So, is there anything else I can check or do before taking it apart and putting new paste on? For now, I have enabled Radeon Chill, which seems to help in 2020 so at least I can fly in it,  but it has little effect in 2024, which I have been scared to use as I don't want to risk any damage to the GPU. I would really love to be able to play 2024 again, especially with the Blackbird being released.

Thanks

@jt233; I find this guy pretty good, it might help.

Thank you, that really seemed to help. I went from temperatures of over 200 at the hotspot, and now they are closer to 160-170. I did try undervolting before, but I don't think I actually messed with any of the custom values, so maybe that's why it didn't work before. I am still wondering, though, if it's normal to have to undervolt the GPU just to prevent the temp from getting so high, or if that still indicates there is an issue with its ability to disperse the heat properly.
