Noctua’s Tower Air Cooler Demonstrates Over 700W Of Heat Dissipation From Intel Xeon CPU

Noctua’s Tower Air Cooler Demonstrates Over 700W Of Heat Dissipation From Intel Xeon CPU

Take that, AIOs.

Most people know Noctua as the king of air coolers, with amazing acoustic and cooling performance from top to bottom. However, for something as large as Intel’s Xeon W9-3495X – a 56-core workstation CPU, surely that has to be strictly AIO territory, right? Turns out, even a monstrous 700W load is still manageable with this Noctua U14S DX-4677 cooler, with no signs of thermal throttling.

Now, the Intel Xeon W9-3495X is not rated at 700W on stock configuration – in fact, the TDP is exactly half that (with boost up to 420W). Safe to say power limits has been specifically removed for this exercise, though in no part of the video has the clockspeeds been shown, aside from the fact that temperature stayed below 100°C. Still, that’s an impressive feat with just air cooling – which transfers heat slower than water does.

Would you say 700W on air cooling is impossible? Here’s our NH-U14S DX-4677 cooling the Intel Xeon w9-3495X at a continuous load of more than 700W! @intel @ASUS @Seasonic @SKhynix pic.twitter.com/35HCtIxL30

From the looks, the Noctua U14S DX-4677 sure looks unassuming: though it’s got some serious heft to it. Measuring 165 x 150 x 111mm and weighs at a seriously hefty 1.14kg – all that metal at >6,000cm² worth of surface area makes it one of the biggest air coolers out there. All the components are plus-sized, with 140mm fans on both ends delivering 140.2m³/h of airflow at just 24.6dBA of noise.

Pokdepinion: I can imagine the heft already with that amount of cooling capacity on tap.
