Why would anyone hate you for AMD? Choosing a Radeon just means that you got a faster card at whatever price point you paid and you did your part to stop nVidia from gaining a monopoly. It also shows that you're not one of the sheep and think for yourself. Those aren't bad traits, they're to be admired!
The only question I have for you is "How did you measure 110°C?" I ask because, I won't lie, 110°C IS EXTREMELY hot for that GPU. I'm talking dangerously hot.
The RX 6700 XT shouldn't be much higher than 80°C at load. Have you played at all with the fan curve in the Radeon software? If you have played with it to make the card quieter, then I recommend putting it back to stock or higher.
Honestly though, I can't see something like a pointless 3% overclock or a reduced fan curve cause a card's temperature to increase by more than 30°C. Unless you've REALLY dropped the fan speed by a lot or have it stuffed into a tiny case with no airflow, it has to be a problem with the card itself.
I would reset everything on the card to stock settings and contact whoever made the card (AMD, ASRock, Sapphire, XFX, etc.) about an RMA. After reading several RX 6700 XT reviews to gauge what the card should be running at under full load, the highest that I saw anywhere was 85°C with most being in the mid-70s.
I don't want to frighten you but 110°C is much hotter than even the R9 290(X) and HD 6990, cards that were infamous for the heat that they could generate:
I think that you probably have a problem with your card's cooler assembly and should get an RMA done.
