Dell XPS Desktop Special Edition: Thermals, Power And Acoustics
Even though the Core i7-10700K has an unlocked multiplier, the XPS Desktop Special Edition is not designed for overclocking. Both the BIOS and stock cooling configuration are not up to the task. You could turn to Intel's Extreme Tuning Utility (XTU) if you really wanted to, but we kept the the system parameters as they shipped.
Here is one place where falling to the bottom of the graph is a good thing. In this case, the XPS Desktop Special Edition only drew 28W at idle, and sometimes just 27W. And at full load, we measured 420W, the same as Maingear's 2019 Vybe. This is after letting the stress tests run for around 30 minutes, by which time some throttling kicks in. Our peak wattage at the very beginning of the stress testing was 510W. Despite the PSU being at 500W model, it was able to go beyond its rating.
XPS Desktop Special Edition Thermals And Acoustics
While under load, we tracked the system's thermals and acoustic behavior, driven by a single case fan (exhaust), the CPU air cooler, and two fans on the graphics card. Below are the results....
The CPU temperature peaked at 97°C—pretty toasty—before throttling kicked in, which dropped the clockspeed to 3.83GHz after running at 100 percent load for 30 minutes. At that point, the CPU temp hovered around 89°C, while the GPU temp held steady at 74°C.
