Noctua NH-U14S DX-4677 - User Manual

Take the fans off the cooler.
Dear customer,
Thank you very much for choosing the Noctua NH-U14S DX-4677.
Our DX line of coolers has become a default choice in high
performance quiet cooling solutions for Intel Xeon processors,
and I’m confident that you will be able to sense some of the
research, attention and care we’ve put into making this product.
Enjoy your NH-U14S DX-4677!
Yours sincerely,
Roland Mossig, Noctua CEO
When attaching the CPU carrier frame to the base of the heatsink,
turn the heatsink upside down so that the base is facing upwards.
Carefully put it down onto the tips of the heatpipes and secure
it with your hand so that it cannot tilt and that the fins cannot
get bent.
Remove the plastic protection cover from the base of the heatsink
and be careful not to damage the layer of pre-applied thermal
compound.
Caution: If you are not using the heatsink for the first time and
it therefore doesn’t have a fresh layer of pre-applied thermal
compound anymore, you need to apply a thin layer of thermal
compound to the CPU yourself before clipping it to the heatsink.
If there are residual traces of previous thermal paste or thermal
pads on your CPU or on the heatsink, please clean them off first.

Note that while the Intel illustrations show a 2U heatsink, the
Noctua NM-XFB9 brackets use the same mounting parts, so the
procedure is identical for Noctua heatsinks.

Plastic CPU carrier frame
Please note that installing an LGA4677 processor and heatsink
requires a plastic CPU carrier frame such as the one shown
above. These carrier frames are included with boxed retail CPUs
and available separately via Intel sales partners for tray type
CPUs. As different CPUs require different carrier frame types
(E1A, E1B or E1C), please make sure to purchase the correct
carrier frame for tray type CPUs.
This manual will guide you through the installation process of the
SecuFirm2™ mounting system step by step.
Prior to installing the cooler, please consult the compatibility
centre on our website (ncc.noctua.at) and verify that the cooler
is fully compatible with your motherboard.
Please also make sure that your PC case offers sufficient clearance
for the cooler and that there are no compatibility issues with any
other components (e.g. tall RAM modules).
Double check that the heatsink and fan clips do not make
contact with the VGA card, other PCIe cards, motherboard heatsinks
or any other components.
Noctua cannot be held responsible for any damage or losses
caused by compatibility issues.
Should you encounter any difficulties, please check the FAQs on our

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Noctua NH-U14S DX-4677 is a high-performance quiet cooling solution specifically designed for Intel Xeon processors, aimed at enthusiasts and professionals seeking superior thermal management for their systems. This cooler is part of Noctua's DX line, known for its robust design and exceptional cooling capabilities. The installation process is guided by a comprehensive manual, ensuring a smooth setup for users.

Function Description:

The primary function of the NH-U14S DX-4677 is to efficiently dissipate heat generated by Intel Xeon processors, thereby maintaining optimal operating temperatures and preventing thermal throttling. This is crucial for systems running demanding applications, servers, or workstations where sustained high performance is essential. The cooler achieves this through a combination of a large heatsink and two high-performance fans, working in conjunction to maximize heat transfer and airflow. The design is optimized to provide quiet operation, making it suitable for environments where noise levels are a concern. The cooler is designed to integrate with the Intel LGA4677 socket, requiring a specific plastic CPU carrier frame for proper installation. This carrier frame, which comes with boxed retail CPUs or can be purchased separately for tray-type CPUs, is vital for securely mounting the processor and heatsink assembly to the motherboard. The manual emphasizes the importance of using the correct carrier frame type (E1A, E1B, or E1C) corresponding to the specific CPU, ensuring a precise and secure fit.

Usage Features:

The NH-U14S DX-4677 is designed for straightforward installation, guided by the SecuFirm2™ mounting system. The process begins with removing the fans from the heatsink using the supplied fan clips, which simplifies the subsequent steps of attaching the heatsink to the CPU. The manual directs users to follow Intel's official installation guidelines for attaching the CPU carrier frame to the heatsink, inserting the CPU into the carrier frame, and then installing the entire CPU/heatsink assembly into the socket. This ensures adherence to manufacturer-recommended procedures for handling sensitive components. A key step highlighted is turning the heatsink upside down when attaching the CPU carrier frame, allowing the base to face upwards. This position facilitates careful placement onto the heatpipes and secure handling to prevent tilting or bending of the fins.

Before installation, users are advised to remove the plastic protection cover from the heatsink's base, taking care not to damage the pre-applied thermal compound layer. This pre-applied compound simplifies the initial setup, eliminating the need for users to apply their own thermal paste for the first time. However, for subsequent installations or if the heatsink has been used before, the manual instructs users to apply a thin layer of thermal compound to the CPU themselves. This ensures optimal thermal conductivity between the CPU and the heatsink. The final step involves reattaching the fans to the heatsink using the provided fan clips and connecting them to the motherboard's CPU fan headers. This completes the physical installation, preparing the system for operation.

The manual also provides crucial pre-installation checks to ensure compatibility and prevent potential issues. Users are urged to consult Noctua's compatibility center on their website (ncc.noctua.at) to verify full compatibility with their motherboard. Additionally, it's important to ensure that the PC case offers sufficient clearance for the cooler and that there are no compatibility issues with other components, such as tall RAM modules. Users should also double-check that the heatsink and fan clips do not make contact with the VGA card, other PCIe cards, motherboard heatsinks, or any other components. These precautions are vital to avoid damage and ensure proper functionality.

Maintenance Features:

Maintaining the NH-U14S DX-4677 involves several considerations to ensure its long-term performance and reliability. For users who are not installing the heatsink for the first time, or if the pre-applied thermal compound is no longer fresh, it is necessary to apply a new layer of thermal compound to the CPU. The manual specifically advises cleaning off any residual traces of previous thermal paste or thermal pads from both the CPU and the heatsink before applying new compound. This ensures a clean surface for optimal thermal transfer and prevents degradation of cooling performance over time.

When it comes to transporting a system with the NH-U14S DX-4677 installed, the manual strongly recommends removing the cooler for safety reasons. This is because it's impossible to reliably calculate or control the forces that act upon a system during transport (e.g., in shipping), and excessive stress could lead to damage. Noctua explicitly states that it cannot be held responsible for any damage arising from excessive stress during transport if the heatsink remains installed. This recommendation underscores the importance of preventive measures to protect both the cooler and other system components.

For removing the heatsink from the socket and the CPU from the heatsink, users are directed to follow the official Intel guidelines. This ensures that the disassembly process is performed correctly, minimizing the risk of damage to the CPU, socket, or heatsink.

Noctua stands behind the quality of its products, offering a warranty period of 6 years and direct, fast, and straightforward RMA service. This commitment to customer support ensures that users can rely on assistance if they encounter any problems with their NH-U14S DX-4677. Users are encouraged to consult the FAQ section on Noctua's website (www.noctua.at/faqs) for common issues and solutions, and to contact the support team at support@noctua.at for any difficulties. This comprehensive support system aims to provide the highest possible level of reliability and convenience for users throughout the product's lifespan.
