AMD has released an official statement regarding the user reports of Radeon RX 7900 XTX graphics cards. In a nutshell, the chipmaker urges affected consumers to contact support.
Although the Radeon RX 7900 XTX is one of the best graphics cards, MBA (Made By AMD) models appear to suffer from overheating. The reference design exhibited hotspots peaking up to 110 degrees Celsius; user feedback claims that the RDNA 3 graphics card shows this behavior even with the cooling fans at full throttle.
"We are aware that a limited number of users are experiencing unexpected thermal throttling on AMD Radeon RX 7900 XTX graphics cards (reference models made by AMD). Users experiencing unexpected thermal throttling of an AMD Radeon RX 7900 XTX should contact AMD Support (opens in new tab)," stated AMD in a statement to Tom's Hardware.
According to AMD, 110 degrees Celsius is the normal junction temperature for the Radeon RX 7900 XTX. However, the current suspicion is uneven contact pressure from the cold plate could be causing the overheating problem on reference Radeon RX 7900 XTX graphics cards. Some user accounts claim that repasting or swapping the TIM for a thermal pad is a viable solution. Nonetheless, AMD's team is currently looking into the issue, whereas PowerColor started to collect user feedback to help in the investigation.
AMD hasn't provided a firm date on when we can expect guidance on the problem. In the meantime, the chipmaker has advised affected users to contact the company's support team. Many consumers have reportedly returned their Radeon RX 7900 XTX graphics cards to AMD or the retailer.
These manufacturers can't wait to take ppl's money by the thousand but don't even have the decency to make sure their products are up to minimum standards.
This is why I don't recommend buying the new AMD GPUs because it's going to take another generation or two to work out the bugs with the Chiplet design/Infinity Cache just like I don't recommend buying a 1st gen Intel GPU .... Let Captain Kirk go boldly where no man has gone before .....

It does appear they're trying to do good to early adopters, so good on AMD for that. I hope they do find the problem and post a clear guidance on what to do about it soon.
Arctic Freezer just went through a replacement situation with some of their AIOs and mine was affected. I'm skilled enough to be able to do the required maintenance on it, so it was painless and helped me avoid returns and such. I hope it doesn't come down to people having to re-paste their own cards, which would be less than ideal, but at least AMD offering quick returns and/or a quick "we'll fix it for you at no cost" service once they find the issue.

Having raised 2 other issues with both AMD and Sapphire regarding my 7900XT (vertical compression of entire screen on 2nd monitor and completely borked Realtek sound output, both of which remain unresolved for 2 weeks), I won't be holding my breath.
By the way, the card is incredibly powerful as compared to my 2080 and runs almost everything at 144 fps ultra settings and 1440p (still struggles with RTX in some games like Cyberpunk like all the reviews said). I just hope AMD will address some issues in their next driver like the crashes with DX12 in The Witcher 3 but other than that it's great.
It boosted up to 110c or at its MHz cap.
It was the design, not a flaw - I don't understand why people freak out about it.
Just buy a waterblock if you are concerned.
