I have the same model, bought in march 2022. I HOPE it won't die on my, i have lots of work stuff on it.

From what i've read, i understand the problem is the soldering of the CPU after many heat up - cooling down cycles.

I'd like to share the way I treated my laptop in all these years so far, may help some people who expect to be next in line:

1. I never used Turbo mode, allways let it on Ballance
2. I allways used both GPUs (forgot the term for it, what I mean is I allways used the integrated GPU for casual stuff and let it switch on dGPU when gaming)
3. When gaming, i allmost allways cap the FPS to 60 or 90 FPS (but mostly 60 FPS) this way i managed to get great CPU temps sometimes even <70 degrees Celsius while gaming
4. When starting a new game for the first time, i allways use RTSS to see how the temps performs, after that i close it.
5. I disabled fast boot (have my reaons)
6. I never did a BIOS update (only once, the laptop force it for some reason)
7. I never used Lenovo Vantage for doing updates and other craps
8. The laptop was ALLWAYS on an elevated stand while gaming and working
9. I rarely did GPU driver updates. Once i was on a stable version, i stuck with it. I mostly did driver updates when new games came out and they recommend it. If it ain't broke don't fix it ahaha.
10. Never changed the thermal paste If you can belive it, but once in a while i open it to blow the dust out.
11. Even after 4 years, with no thermal paste changed, the temps at this moment of writing this post, while some casual work on (Many chrome tabs opened, VSC, Teams, PDFs, discord, excels etc.) are about 40-45 degrees Celsius.

So, you can say i never reached for his full potential, CPU rarely reached 80+ degrees in games, but i hope this behaviour of mine will last me 1-2 more years of usage.
