I saw a report of an Nvidia RTX5070Ti overheating after SU5 was released for MSFS 2024. Normally this would not have caught my eye, but I have that same card and just yesterday I experienced the same thing myself.

I ran MSFS 2024 for the first time in a few weeks, and of course it installed SU5. It worked fine and I ran for a good few hours, but then I started to get rendering glitches that persisted after restarting MSFS and even rebooting the PC. I suspected temperatures and after finding a way to monitor GPU stats I could see MSFS was basically working the GPU hard all the time and temps were in the up to mid-60s sort of range. The card was very hot to the touch, but all fans were working. If I let it cool down things went back to normal. This was running VR headset (Bigscreen Beyond 2) but the high temps persisted  when not in VR mode.

Is it plausible that this is a software matter and not a physical cooling deficiency? I have seen other reports, but it's the internet and I worry that I am seeing one person's experience reported in different places. I guess if it's software it will get fixed in due course. If I see this consistently than maybe I can try falling back to MSFS 2020 for comparison.

Looks like a bad card. Mid-60s for a GPU is nothing.

I think this is a premature diagnosis! Seems more likely the problem was something other than overheating.
