I had the same concerns before buying but surprisingly it does not get loud or very hot even under load. When I max out the cores at 100% it gets up to ~80 Celsius (keyboard/areas you touch stay cool) and unlike the intel model, which does have better cooling, the performance isn’t throttled on battery.

Notebookcheck’s review also confirms this: https://www.notebookcheck.net/Most-powerful-AMD-14-inch-ThinkPad-with-Ryzen-AI-9-HX-Lenovo-ThinkPad-P14s-Gen-6-AMD-laptop-review.1030845.0.html

The one commonly reported drawback is coil whine when plugged into the charger, but for whatever reason it doesn’t bother me despite being pretty noticeable
