Noctua NH U14S DX 4677 Air CPU Cooler

The Noctua NH-U14S DX-4677 Air CPU Cooler is a dedicated cooling solution for Intel Xeon LGA4677 processors. This premium-quality quiet CPU cooler combines a large heatsink with two high-performance fans. It ensures optimal thermal performance for demanding workstation and server environments.

High-Performance Cooling for Intel Xeon:

Dedicated LGA4677 Compatibility:

The NH-U14S DX-4677 is specifically designed for the Intel LGA4677 socket. Due to its customized larger base, it offers optimal contact and cooling performance for Intel Xeon processors. However, please note that it cannot be used on smaller sockets and is incompatible with Noctua’s mounting kits for these sockets. Installing an LGA4677 processor and heatsink requires a plastic CPU carrier frame, which is included with boxed retail CPUs or available separately for tray type CPUs.

Dual NF-A15 PWM Premium Fans:

This cooler includes two NF-A15 PWM premium fans. These fans feature Noctua’s proprietary SSO2 bearing and advanced aerodynamic design. They operate at a maximum rotational speed of 1500 RPM, delivering a powerful airflow of 140.2 m³/h. Despite their high performance, they maintain a low acoustical noise level of 24.6 dB(A), ensuring quiet operation crucial for professional environments.

Robust Construction and Easy Installation:

Premium Materials for Optimal Heat Transfer:

The NH-U14S DX-4677 is constructed from high-quality materials to ensure optimal heat transfer and durability. It features a copper base and heat-pipes, along with aluminum cooling fins. The soldered joints and nickel plating further enhance its longevity and thermal performance.

SecuFirm2™ Mounting Kit and Pre-applied Thermal Compound:

The cooler includes a SecuFirm2™ mounting kit specifically designed for LGA4677. This ensures straightforward and secure installation. Additionally, NT-H1 high-grade thermal compound comes pre-applied, providing excellent thermal conductivity right out of the box. An NM-SMT5 Torx® T30 mounting tool is also included for convenience during installation.

Comprehensive Specifications and Long-Term Reliability:

Detailed Fan and Cooler Specifications:

The NH-U14S DX-4677 stands 165mm tall (with or without fans), with a width of 150mm and a depth of 111mm (with fans). It weighs 1136g with fans. The NF-A15 PWM fans offer a minimum rotational speed of 300 RPM at 20% PWM. They have an input power of 1.56 W and operate within a voltage range of 12 V.

Exceptional Longevity:

Noctua products are renowned for their impeccable quality and outstanding longevity. The supplied NF-A15 fans boast an MTTF (Mean Time To Failure) rating of more than 150,000 hours. This commitment to durability ensures a reliable and long-lasting cooling solution for your Intel Xeon system.
