Heat and ventilation are issues with pretty well all modern thin laptops. That's especially true on small and very thin models such as XPS 13. Always use the laptop on a hard surface, never on a bed, couch, pillow, etc. You might want to do what I did: I took a strip of lumber, about 3.5 cm. wide x 2 cm. high (1.5" x 3/4"}, and the length equal to the width of my laptop. I routed out two notches to accommodate the laptop's rear feet. The rear of the laptop sits in those notches, propping up the rear by 2 cm. That provides better ventilation underneath the laptop and makes it easier for the fan to draw in air via the bottom vent.  It's cheap insurance, and also positions the keyboard at a slight angle that makes typing more comfortable. It won't solve a major heat issue, but it helps somewhat. You may find that an electric cooling pad is helpful. Some forum members install Dell Power Manager app from the Microsoft Store and choose a cool thermal profile.
Hi,last month (October 2022) I bought a new Dell XPS 13 Plus 9320 with Ubuntu 22 as OS.The specs follow:CPU: 12th Gen Intel i7-1260P (16) @ 4.700GHzRAM: 32 GBSSD: 512 GBIf I ran simple Python scripts on 5-6 cores (lasting, say, 1 hour), the cores reach easily 80-85 Celsius degrees.If I ran some game involving graphics (even with low resolution), the cores reach even higher temperatures, usually around 90-95 degrees. These temperatures slightly worsen when the plague adapter is connected.Yesterday I tried a stress test (Python + game + plague adapter), and some cores touched the 100 Celsius degrees. These high temperatures last for the time such processes keep running. Whenever I'm just browsing or doing simpler staff the temperatures are around 40-60 Celsius degrees, which I guess it's normal.I read online that this laptop often experiences overheating issues. Should I worry?Thanks in advance.
Dell XPS 13 Plus 9320 overheats or not?
