Possibly. Some XPS models (~9310) cheaped out on the WiFi chipset, which was really bad at reconnecting after sleep/suspend on Win 10/11 right out off the box.
Tried a live Linux install and it worked perfectly, so made the switch as there was no Win-only software that I needed.
Hot, yes. Usually quite comfortable though. Though both depend on the design. And there are cooling options out there; small airflow systems for the heads, and cooling vests that yhe other commentor posted a link to.
