2026 Dell XPS 16 runs noticeably warmer than last generation model

the 2026 XPS 16 represents the biggest update to the series yet since the original controversial redesign in 2024. The model is now significantly thinner, leaner, and sexier due largely to the lack of discrete graphics options to reduce the number of necessary parts including the relatively dense vapor chamber cooler. The resulting smaller cooling solution has therefore led to some temperature differences between the two model years.

Our temperature maps and performance metrics below compare the 2025 Dell 16 Premium with Core Ultra 7 255H and discrete GeForce RTX 5070 graphics to the new 2026 Dell XPS 16 running on Core Ultra 5 325 Panther Lake. When subjected to similar stressful conditions, the newer model would sometimes run noticeably warmer both in terms of surface temperatures and core temperatures. For example, surface temperature hot spots on the 2026 model when running Cyberpunk 2077 would reach 43 C on both the keyboard deck and bottom cover compared to just 37 C on the 2025 Dell 16 Premium with more powerful graphics. Core temperature would reach 89 C on the newer model compared to just 75 C on the outgoing model.

When running Prime95 to stress the CPU only, the processor in the 2026 model would reach 86 C to be cooler than than the processor in the 2025 model by about 7 C. Most notably, however, surface temperatures would still be warmer on average with the newer design despite the slightly cooler core temperature under this particular scenario.

Beyond the temperature differences, the 2026 model benefits from quieter fan noise than the outgoing model. Thus, while the new XPS 16 may generally run warmer, it's at least not as loud when under load. More comparisons and benchmarks between the two machines can be found on our review of the 2026 XPS 16 below.
