Noctua has demonstrated the effectiveness of its NH-U14S DX-4677 air cooler by using it to cool down Intel's 56-core Xeon W9-3495X at full load and drawing 700 W of power. Despite the popularity of all-in-one (AiO) liquid coolers, Noctua wants to prove that air coolers are more than capable of handling even the most high-end CPUs, even at continuous load and without throttling.
Although the video does not provide the full details of the CPU settings, it is still an impressive feat, especially considering the high power draw. This suggests that the CPU was pushed beyond its default settings for demonstration purposes. The setup includes the aforementioned Intel's 56-core Xeon W9-3495X CPU, running on an ASUS Pro WS W790E-SAGE SE motherboard with SK Hynix DDR5 EC8 RDIMM, and powered by Seasonic's PX-1600 PSU.
It is important to note that the Noctua NH-U14S DX-4677 is a substantial CPU air cooler with a large copper base, eight copper heatpipes, and a large aluminium heatsink. It is specifically designed for Intel's LGA4677 socket Xeon CPUs and weighs 1136 g with fans. It comes with two Noctua NF-A15 HS-PWM fans spinning from 300 to 1500 RPM and providing 140,2 m³/h of airflow at 24,6 dB of noise.
