Noctua, a leading supplier of air cooling, is one of the few manufacturers of CPU cooling systems that does not have a closed-loop cooling system in its lineup. The company’s latest air cooler, the NH-U14S DX-4677, is capable of cooling Intel’s 56-core Xeon W9-3495X, which consumes 700W of power, so the company probably doesn’t need them.
These days, most enthusiast-grade desktops and workstations use all-in-one (AIO) liquid cooling systems. This is more efficient than air coolers and can better handle modern CPUs, which can draw far more than their rated thermal design power when working. briefly, but in turbo boost mode). However, as Noctua’s demonstration shows, while liquid coolers are efficient, larger air coolers work well.company new NH-U14S DX-4677 Intel’s 56-core Xeon W9-3495X can cool when the load draws over 700W and doesn’t throttle.
“Is 700W impossible with air cooling?” noctua’s tweet“The NH-U14S DX-4677 cools the Intel Xeon w9-3495X at over 700W continuous load!”
The company doesn’t reveal if the CPU is overclocked (or at what clock speed it’s running), but in the video, the temperature remains below 100°C. I suspect that the UEFI BIOS increased its power limit to demonstrate the functionality of the cooler.

The Noctua NH-U14S DX-4677 is a large aluminum tower cooler featuring a nickel-plated copper base and six thick U-shaped nickel-plated heat pipes. The cooler measures 6.5 x 5.9 x 4.4 inches (165 x 150 x 111 mm), weighs 2.5 pounds (1.14 kg) and includes two Noctua NF-A15 HS-PWM fans, making it ideal for compact PC cases. It may not fit. The heatsink fins are slightly curved to maximize surface area and optimize airflow.
The cooler has a total fin surface area of over 6000cm² making it one of the largest air coolers available. Noctua says the two 140 mm fans produce an airflow of around 140.2 m³/h and a maximum noise of 24.6 dBA.
The Noctua NH-U14S DX-4677 is specifically designed for Intel’s Xeon processors, providing excellent cooling performance and reliability with a 6-year warranty (and 150,000 hours MTTF with fans).
