Thermalright Assassin X 120R SE Plus CPU Cooler - 4×6mm Heat Pipes vs Noctua NH-L9x65 chromax.Black

Introduction to CPU Coolers

When it comes to cooling your CPU, the choice of cooler can significantly impact performance and noise levels. In this article, we will compare two CPU coolers: the Thermalright Assassin X 120R SE Plus and the Noctua NH-L9x65 chromax.Black. Both coolers have their unique features and price points, making them suitable for different user needs. The Thermalright cooler is priced at C$25.59, while the Noctua model is significantly more expensive at C$101.95.

Design and Build Quality

The Thermalright Assassin X 120R SE Plus features a robust design with 4×6mm heat pipes that improve thermal performance. This cooler employs a Double PWM fan setup, allowing for efficient cooling at a noise level of just 25.6 dB(A). On the other hand, the Noctua NH-L9x65 chromax.Black is a compact low-profile cooler with a height of only 65mm, making it ideal for small form factor builds. Its 95x95mm footprint ensures it does not interfere with RAM or PCIe slots, facilitating easier installation. While both coolers feature high-quality construction, the Noctua’s award-winning design is particularly tailored for compact builds.

Cooling Performance

In terms of cooling efficiency, the Thermalright Assassin X boasts a maximum airflow of 66.17 CFM, which is impressive for maintaining low temperatures during heavy CPU loads. The presence of four heat pipes enhances its thermal transfer capabilities, effectively dissipating heat. Conversely, the Noctua NH-L9x65 relies on its highly optimised NF-A9x14 slim fan. While it is designed for low to moderate heat dissipation, it excels in ultra-quiet operation, which is ideal for users seeking a silent computing environment. The Thermalright cooler presents a more aggressive cooling performance, while Noctua focuses on noise reduction.

Noise Levels

The Thermalright Assassin X operates at a noise level of 25.6 dB(A), which is relatively quiet but not as silent as the Noctua NH-L9x65. The Noctua cooler features a Low-Noise Adaptor, allowing for automatic speed control that further reduces noise during operation. For users who prioritise a quiet system, the Noctua’s design stands out, especially in environments where silence is crucial. Although the Thermalright offers solid cooling performance, it does not match the Noctua in terms of noise reduction capabilities.

Compatibility

Regarding compatibility, the Thermalright Assassin X supports a wide range of CPU sockets, including Intel's LGA 1150/1156/1200/1700 and AMD's AM4/AM5. This broad support allows for versatility across various builds. In comparison, the Noctua NH-L9x65 also offers excellent compatibility, supporting Intel LGA 1851, LGA 1700, LGA 1200, LGA 115x, and AMD AM4/AM5. Both coolers provide corresponding mounting plates or fasteners for their supported sockets, ensuring ease of installation. However, the Thermalright cooler has a slight edge in terms of socket variety.

Installation Process

Installation can vary significantly between different CPU coolers. The Thermalright Assassin X comes with a straightforward mounting system that is designed for ease of use across multiple socket types. Meanwhile, the Noctua NH-L9x65 features the SecuFirm2 mounting system, which is noted for its user-friendliness and secure fit. Both coolers promise a relatively simple installation process, but the Noctua system is often praised for its reliability and ease of assembly, making it a favourite among DIY enthusiasts.

Price Comparison

Price is a key factor when selecting a CPU cooler. The Thermalright Assassin X is priced at C$25.59, making it an affordable option for budget-conscious consumers. In stark contrast, the Noctua NH-L9x65 is significantly more expensive at C$101.95. While the higher price of the Noctua may be justified by its quality and performance in specific scenarios, those on a budget will find the Thermalright to be a compelling choice without compromising essential cooling capabilities.

Which should you buy?

Choosing between the Thermalright Assassin X 120R SE Plus and the Noctua NH-L9x65 chromax.Black ultimately depends on your specific needs. If you are looking for an affordable, high-performance cooler with broad compatibility and solid airflow, the Thermalright Assassin X is an excellent option. However, if your priority is a compact, ultra-quiet cooler for a small form factor build, the Noctua NH-L9x65 is worth the investment. Weighing performance against price, each cooler has its strengths, making them suitable for different types of users.
