## Long description

Noctua NH-U14S DX-4677 is a premium CPU cooler designed for Intel LGA4677 platforms, combining a 140mm-class heatsink with two NF-A15 140mm PWM fans. The cooler features an enlarged copper contact surface tailored to the large integrated heat-spreaders of LGA4677 Xeon processors and includes the SecuFirm2™ mounting system with standard Intel parts and pre-applied NT-H1 thermal compound for straightforward installation.
Advantages
The NH-U14S DX-4677 offers high cooling performance with low noise thanks to its dual NF-A15 fans and a large fin array with six heatpipes. Compatibility with Intel E1A, E1B and E1C carrier frames and the inclusion of a Torx® T30 mounting tool simplify installation on workstations and servers. Pre-applied NT-H1 thermal paste and a proven SecuFirm2™ mounting system provide reliable thermal contact and long-term stability. A 6-year manufacturer’s warranty covers the complete package.
Key specifications
Socket compatibility: Intel LGA4677 (Xeon Scalable 4th gen and workstation Xeon w9/w7/w5/w3)
Heatsink size: based on 140mm NH-U14S design
Copper contact surface: 70 × 56 mm (enlarged for LGA4677 IHS)
Heatpipes: 6
Fans: 2 × Noctua NF-A15 140mm PWM
Fan control: PWM (automatic speed control via motherboard)
Thermal compound: Pre-applied NT-H1
Mounting system: SecuFirm2™ compatible with Intel carrier frames (E1A, E1B, E1C); includes Torx® T30 tool
Warranty: 6 years
How to use
Install the cooler onto an LGA4677 CPU using the included SecuFirm2™ mounting components together with the appropriate Intel carrier frame (E1A, E1B or E1C). Place the pre-applied NT-H1 thermal compound side down onto the CPU IHS and follow the familiar Intel mounting sequence using the Torx® T30 tool to secure the heatsink. Connect both NF-A15 fans to the motherboard fan headers to enable PWM control so the fans run quietly at light loads and increase speed under higher thermal load.
Recommendations
For optimal performance, ensure the correct carrier frame type is present and installed as per Intel guidelines, maintain adequate case airflow, and verify PWM fan headers are enabled in BIOS for automatic speed control. This cooler is intended for Xeon workstations and servers where low-noise, high-efficiency air cooling for LGA4677 CPUs is required.
