Noctua NH-U9S vs Thermalright Assassin X120 Refined SE CPU Air

Overview of the Noctua NH-U9S

The Noctua NH-U9S is a premium CPU cooler designed for those who prioritize performance and quiet operation. Priced at $69.95, it features a compact single-tower design that is only 125mm in height, making it ideal for small form factor builds, HTPCs, and ITX systems. This cooler is renowned for its strong cooling performance without sacrificing compatibility with RAM or PCIe slots, which is a significant advantage for users with space constraints.

The NH-U9S is equipped with a highly optimized NF-A9 92mm fan that supports PWM functionality, allowing for automatic speed control and ultra-quiet operation. Additionally, it comes with high-end NT-H1 thermal paste and a SecuFirm2 mounting system for easy installation across a range of Intel and AMD sockets. This cooler is backed by Noctua's reputation for quality and a six-year manufacturer’s warranty, making it a reliable choice for high-performance systems.

Overview of the Thermalright Assassin X120 Refined SE

The Thermalright Assassin X120 Refined SE is an affordable CPU cooler priced at just $17.90, making it about 74% cheaper than the Noctua NH-U9S. This cooler features a more traditional design with a height of 148mm, which is suitable for medium-sized cases. The Assassin X120 is equipped with four heat pipes and a TL-C12C PWM fan, which operates at a maximum speed of 1550 RPM while maintaining a noise level of 25.6 dB(A).

Thermalright has been in the market for over 20 years, focusing on the research and development of computer accessories, which adds to the credibility of the Assassin X120. With a lightweight design of 0.645kg, it is easy to handle during installation. Compatibility is broad, supporting various Intel and AMD sockets, making it a versatile choice for many users looking to upgrade their cooling solutions without breaking the bank.

Performance Comparison

When it comes to performance, the Noctua NH-U9S is designed for users who demand high efficiency and low noise. Its optimized NF-A9 fan ensures that the cooler operates quietly while providing strong cooling performance, particularly in compact builds. Although specific cooling performance metrics are not provided, the reputation of Noctua implies that users can expect superior thermal management.

In contrast, the Thermalright Assassin X120 Refined SE, while significantly cheaper, is also positioned as an effective cooler with its AGHP technology and four heat pipes. The fan's airflow reaches 66.17 CFM, which is decent for budget builds. However, the overall cooling performance may not match the NH-U9S, especially under heavy loads, given the price difference. Users might find that the Assassin X120 is suitable for mid-range systems but may struggle with higher-end CPUs compared to the Noctua.

Installation Process

The installation process is a vital aspect for many users considering a CPU cooler. The Noctua NH-U9S includes a SecuFirm2 mounting system, which simplifies the installation process across multiple Intel and AMD sockets. Users can expect a straightforward installation experience, thanks to the included high-end NT-H1 thermal paste, which is known for its excellent thermal conductivity.

On the other hand, the Thermalright Assassin X120 comes with metal fasteners designed for various Intel and AMD platforms. While it also aims for an easy installation, it may not provide the same level of user-friendliness as the NH-U9S. Given the differences in mounting systems, those who are less experienced with cooler installations may prefer the Noctua for its ease of use.

Compatibility

Compatibility is another crucial factor to consider when comparing CPU coolers. The Noctua NH-U9S is compatible with a wide range of Intel and AMD sockets, including LGA1700, LGA1200, and AM4. Its compact design ensures that it does not overhang RAM or PCIe slots, making it a great choice for smaller builds where space is at a premium.

The Thermalright Assassin X120 also supports a wide array of Intel and AMD sockets, including LGA 1150, 1151, and AM5. However, its larger height of 148mm may limit its usability in very compact cases. Users with standard to medium-sized cases will likely find the Assassin X120 compatible with their setups, but those with space constraints may face challenges.

Noise Levels

Noise levels are critical for users who require a quiet computing environment. The Noctua NH-U9S is designed for ultra-quiet operation, with its NF-A9 fan providing excellent performance without excessive noise, which is a significant selling point for many users. This cooler's low-noise adaptation technology ensures that it remains unobtrusive even under load.

Conversely, the Thermalright Assassin X120 operates with a maximum noise level of 25.6 dB(A). While this is relatively quiet for a budget cooler, it may not match the near-silent operation of the NH-U9S. For users who prioritize noise levels alongside cooling efficiency, the Noctua may be the more appealing option.

Price and Value

The most striking difference between these two coolers is their price. The Noctua NH-U9S retails for $69.95, which is a significant investment compared to the Thermalright Assassin X120 Refined SE's price of $17.90. While the Thermalright provides essential cooling capabilities at a lower cost, the NH-U9S is crafted for those who are willing to pay more for superior performance, quieter operation, and a longer lifespan backed by a six-year warranty.

In terms of value, the Noctua cooler may be better suited for high-performance builds, while the Thermalright is an excellent choice for budget-conscious users or those with less demanding cooling needs. Users should weigh their specific requirements against their budget when making a decision.

Which should you buy?

In conclusion, the choice between the Noctua NH-U9S and the Thermalright Assassin X120 Refined SE ultimately depends on your specific needs and budget. If you prioritize top-notch performance, quiet operation, and are willing to invest in a reliable cooler, the Noctua NH-U9S is the way to go. However, if you are looking for a budget-friendly option that still delivers decent cooling for mid-range systems, the Thermalright Assassin X120 is a viable alternative. Each cooler has its strengths, making the final decision hinge on the individual user's requirements and preferences.
