When I ran the benchmark test at 24 degrees Celsius, the heat was generated and dissipated nicely, so I checked the sound and heat first. The fan noise of the XPS 13 was just loud enough not to exceed 51.0 dB.
The XPS 14 is almost the same at 50.1dB.
Now, let's check the heat. Both the XPS 13 and the XPS 14 have exhaust vents in the hinge area, as shown below.
The hinge got extremely hot during the benchmark.
When the thermo sensor was placed close to the XPS 13, it was confirmed that the temperature had risen to a maximum of nearly 47 degrees.
The top center of the keyboard was also hot, while the trackpad and keys were relatively cool.
I tried placing my hand on it. The trackpad, which I often place my hand on, is only slightly warmer than body temperature, so it doesn't seem to be a big problem even if I stay still for a while. The top center of the keyboard is quite hot, but it doesn't interfere with typing. As long as you don't keep your hand near the top center of the keyboard all the time, you probably won't be affected by the heat wave.
The same goes for the XPS 14.
The hinge had risen to nearly 49 degrees.
The top center area of the keyboard also gets hot.
When I looked at the exhaust vent on the back, hot air was blowing out like a jet.
It has risen to 51.6 degrees.
I measured the operating time when watching YouTube with the screen brightness at maximum. The nominal battery capacity of the XPS 13 (left) is 55Wh, and the nominal battery capacity of the XPS 14 (right) is 69.5Whr. The XPS 13 turned off about 4 hours and 40 minutes after the measurement started, and the XPS 14 turned off about 7 hours after the measurement started.

After entering safe mode at 3%, I checked the charging speed from 3%. I reduced the screen brightness to 50% and charged the device, and both models reached full charge in about 2 hours and 30 minutes.
