Noctua NH-U14S DX-4677 CPU Cooler LGA4677

Noctua NH-U14S DX-4677 is a high-end air cooler aimed at LGA 4677 platforms, where cooling serious CPU loads is critical. The large aluminum radiator and the included two fans sized 150 x 140 x 25 mm are designed to keep temperatures under control during prolonged load. The noise level is only 24.6 dBA, which is important if the machine is running constantly next to you. There is no RGB – the focus is entirely on efficiency, reliability, and pure functionality.

What you get

With this cooler, you get a massive aluminum block measuring 150 x 111 x 165 mm, combined with two fans that provide serious airflow of 82.52 CFM / 140.2 m3/h. This allows for stable cooling of an LGA 4677 processor even during long renders, virtualization, or heavy computational tasks. PWM control via the 4 PIN connector gives you precise control of the RPM based on temperature, so the system is quiet at idle and aggressive under load. The SSO2 Bearing is optimized for long life and low noise, which is important for 24/7 workstations. The package also includes pre-applied NT-H1 thermal paste and a complete SecuFirm2 mounting kit for LGA 4677, so installation is straightforward without worrying about compatibility and additional parts.

• Specialized support for LGA 4677, making it a direct choice for modern workstation and server CPUs on this platform.
• Large dual fan set with dimensions 150 x 140 x 25 mm, providing serious airflow area and more even cooling of the radiator.
• High airflow of 82.52 CFM / 140.2 m3/h, suitable for CPUs that operate continuously under high load.
• Low noise level of only 24.6 dBA, ensuring that even under active operation the system remains quiet and unobtrusive.
• 4 PIN PWM connector for intelligent control of RPM based on temperatures and profiles in the BIOS or motherboard software.
• Use of SSO2 Bearing for longer fan life and lower vibration during operation.
• The package includes SecuFirm2 mounting kit for LGA4677, NA-YC1 4-pin PWM y-cable, NM-SMT5 Torx® T30 tool, and NT-H1 thermal paste (pre-applied) for easy and clean installation.

Who it is suitable for

NH-U14S DX-4677 is mainly suitable for those building a serious LGA 4677 system – a workstation, server, or high-end productivity machine where stability under long load is more important than flashy lights. If you are after compact cases or a heavily RGB-oriented build, the size and lack of lighting may not appeal to you.

The combination of high airflow, low noise, and a ready-to-install kit for LGA 4677 makes this Noctua cooler a very sensible choice when you need reliable, predictable, and quiet air cooling.
