Thermals & Noise Under Pressure

The proprietary Cold Wave 2.0 cooling solution combines a liquid-metal TIM with dedicated heatsinks for the CPU, memory, and SSD modules. Under light to moderate workloads, the system remains nearly inaudible, with fan speeds hovering in the 20–35 dB range at a distance of one meter. When gaming or running synthetic benchmarks, fans ramp to 45–50 dB, still lower than many full-tower PCs. Temperature logs show the CPU cores typically peak at 75–80 °C under heavy multi-threaded stress tests, while the SSD stays under 65 °C. A few users have reported thermal spikes during extended GPU loads, but most find accents of balanced heat management to be in line with expectations for such a compact footprint.

Comparison with Competitors

Positioned against the Beelink SER7 and Intel’s high-end NUC models, the UM790 Pro often offers superior GPU performance due to the Radeon 780M’s faster frequencies compared to competing iGPU solutions.
