Mobile CPUs do tend to ride the throttle limits, and Intel chips do tend to have max power limits that are quite high.
13900HX can pull up to 157W for brief periods, even the regular H chips can pull 115W.
HWInfo64 might be worth a go. CoreTemp is usually pretty reliable for CPUs.
All depends on the cooling capacity of the laptop. You might consider re-doing the thermal compound. What they use is quite stable and could last a significant chunk of the laptop's life. But there are better thermal compounds that need to be replaced more often, so every 3-4 years vs 7-8.
For heavy gaming it is always recommended to have a cooling pad, or to elevate the laptop so the vents have direct access to intake and exhaust air.
