Temperatures below 110C on your hotspot are basically safe. Below 100C is the comfort zone. Below 90C = overclocking party invitation.
As far as you're within 110C and your junction-to-hotspot delta ain't all around the place (70C junction and 95C hotspot is sane; 70C junction and 110C hotpot is off) you don't need to worry about it much. Your GPU will die... about a dozen years from now. And what can I say, 12 y.o. GPU rarely do deliver playable FPS in recent titles.

Of course, I don't expect the GPU to work for life. If I can use a GPU for 5 years, that is enough time for me. Before switching to AMD GPU, the hotspot temperature of the GPUs I used (GTX 1070, RTX 2060 Super, RTX 3060Ti) was 75°C at most. But when I switched to the RX 6700XT, I was disappointed when I saw 100°C. When I sent it to technical service due to a heating problem, they sent me a brand new card. Of course, since the fan curve in the Sapphire Pulse 6000 series was problematic, I managed to keep the GPU temperature between 68-72°C and the hotspot temperature between 78-83°C by manually adjusting the fan.

I undervolted, set the MHz value to 2581 and the mV value to 1150, and now the GPU temperature is between 55-63°C and the hotspot temperature is between 74-78°C.

I'm happy with the GPU now. However, I feel like I will have problems with this issue again in the future.

You cant really compare hotspot temps between AMD/nVidia. Apples and oranges...
Both brands reveal exactly what they want users to see. So you cant be sure whats really going on inside the GPU die.
I think AMD has been more honest about it since Zen2/RDNA1 first came out in 2019.

Of course there is the cooler/contact implementation subject by vendors.
I think most of them are just seeking ok-ish cooling performance because of the 110C operating limit.

It is absolutely a die/coldplate contact issue.
I found a way to bring my 6700 XT to what it was supposed to be. Once I solved my contact issue it basically unlocked tons of OC and UV potential. The before and after was insanely different. I also don't cringe anymore when I peak at HWinfo64. Seeing 100-110°C and/or 15-30°C delta was sooo unsettling... undervolting was OK, but still was seeing high deltas at times and poor freq behavior, poor OC and UV performance. The stable ranges are WAY larger, I can hit much higher freq and lower voltages now. Even at stock settings after the fix I was seeing a performance increase due to higher and sustained clocks.
You will void the warranty though... personally, if I can't fix it myself I replace it. To each his own. Personally don't like RMA-ing, never had a good experience. I also work in the Tech industry and take electronics/computers/servers apart to service/refurbish regularly so this was right up my ally.

Unfortunately, after 8 months, the GPU's hotspot temperature rose again. On the first day of the GPU, the normal temperature was 70 and the hotspot temperature was 81. Of course, I used it with undervolt since the first day and while the normal temperature was around 62, the hotspot was in the range of 80-85. When I tried to test without undervolt last night, the normal temperature was in the 62-65 range, but the hotspot was close to 90 degrees again.

I think this will be an inevitable end for me. :fear:

Keep in mind that hotspot temps temps and size of a difference tend to rise with growth of ambient temp. Maybe your case.

I have a mesh case. There are 2 Akasa Viper AK-FN063 fans on the front of the case as intake fans. There are 2 Arctic F120 exhaust fans on the top and 1 Arctic P120 exhaust fan at the back. My cafe is this;

The air temperature outside is in the range of 18-20 degrees.

It doesn't matter what cooling config you have - you won't fight much temperature growth from higher ambient with airflow. Then it just cools your components with warmer air ;)

Ofc there's always option that thing responsible here is paste degradation, but if your ambient change recently, I would first pay attention to it when doing measurements.
