Noctua Cools Down 700 W 56-core Intel Xeon W9-3495X on Air
Noctua has showcased its NH-U14S DX-4677 air cooler in action, cooling down Intel's 56-core Xeon W9-3495X at full load and drawing 700 W of power. While all-in-one (AiO) liquid coolers are popular these days, Noctua aim to show that air coolers are more than capable on handling even the most high-end CPUs, even at continuous load and without throttling.
While the video does not show the full details of the CPU settings, it is still an impressive feat, especially considering the high power draw, which suggest that the CPU was pushed way beyond its default settings for demonstration. The setup includes the aforementioned Intel's 56-core Xeon W9-3495X CPU, running on ASUS Pro WS W790E-SAGE SE motherboard with SK Hynix DDR5 EC8 RDIMM, and powered by Seasonic's PX-1600 PSU.
Bear in mind that the Noctua NH-U14S DX-4677 is a hefty CPU air cooler with large copper base, eight copper heatpipes, and large aluminium heatsink. It is designed specifically for Intel's LGA4677 socket Xeon CPUs, and it 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.

I wonder if it comes with a support bracket like gpu supports.
I know Noctua are legends, but 700W on air. I've run enough of CPUs in my day to know what it means. Enough to say that 700W that's like 2 360mm 30mm rads of heat capacity on custom loop. Servers yeah, they don't care about 150dB noise from 100 of Delta 80mm thick fans, but even still there is visible trend for liquid cooling in enterprise segment. Intel has provisioning on new Xeons for 700W/socket. In 2/4 socket configuration that's nearly 3kW on CPUs alone. Insanity doesn't even come close to describing where we have arrived in terms of power requirement.
It's super ironic how people joked from all the PC furnaces we had, P1, P4 or 295, 480, 690 etc. It's 2-3x as bad now.
Also keep in mind that most benchmarks and reviews are conducted on open benches, while all of you will run your computers in enclosed cases. In most situation, case airflow will be the bottleneck, no matter how fancy the CPU cooler is. But once you have sufficient air flow, the tower cooler might end up performing even better than you think.
These news are about sky is blue?
It is much harder to cool down a very powerful and small surface area like lasers and LED's not this thing.
I still prefer my low maintenance tower cooler, but I also set the fan ramp up time to as high as the bios settings would allow to avoid hearing getting the constant up and down
If so I am more amazed about what a horrid piece of silicon Intel made rather than the cooler.The other being that with an AIO you can direct all the heat outside of the case, makes a difference if you have a high TDP air cooled card.

Keeping it hungry by drip-feeding it 700 W amounts to torture.
