Introduction
In this comparison, we will explore two low-profile CPU coolers: the Noctua NH-L9x65 and the Thermalright AXP-120-X67 Black ARGB. Both are designed for compact builds but have distinct features and price points that cater to different needs. The Noctua NH-L9x65 is priced at $69.95, while the Thermalright AXP-120-X67 is notably cheaper at $32.59, making it about 53% less expensive.
Design and Build Quality
The Noctua NH-L9x65 boasts a compact design with a total height of only 65mm, making it an excellent choice for HTPCs and small form factor builds. Its brown aesthetic and low-profile dimensions ensure it does not overhang RAM or PCIe slots, enhancing compatibility across various motherboards. In contrast, the Thermalright AXP-120-X67 has a slightly taller profile at 67mm, but it is still considered low-profile. The design incorporates a sleek black finish and ARGB lighting, appealing to users who prefer a more modern look. Both coolers are made with high-quality materials, but Noctua's reputation for durability may give it an edge.
Cooling Performance
Cooling performance is critical in CPU coolers, and both products deliver solid results. The Noctua NH-L9x65 features a highly optimized NF-A9x14 slim 92mm fan, which allows for automatic speed control and ultra-quiet operation, making it suitable for environments where noise is a concern. On the other hand, the Thermalright AXP-120-X67 is equipped with a 120mm PWM fan that can reach speeds of up to 1800 RPM, offering an airflow of 59 CFM with a noise level of 26.1 dB(A). While the Noctua is recommended for CPUs with low to moderate heat dissipation, the Thermalright's specifications suggest it can handle slightly more demanding scenarios.
Installation Process
When it comes to installation, both coolers are designed for ease of use. The Noctua NH-L9x65 includes a SecuFirm2 mounting system that simplifies the process across various Intel and AMD sockets, including LGA1700, LGA1200, and AM4. This level of compatibility is beneficial for users who may upgrade their systems in the future. Meanwhile, the Thermalright AXP-120-X67 comes with metal fasteners compatible with a wide range of Intel and AMD platforms, ensuring straightforward installation. Both cooler designs focus on user-friendliness, but the Noctua's additional mounting options may provide a slight advantage.
Noise Levels
Noise levels are an essential consideration for many PC builders, especially those focusing on silent operation. The Noctua NH-L9x65 is renowned for its ultra-quiet performance, largely due to its advanced PWM fan design and Low-Noise Adaptor. This makes it ideal for users sensitive to noise. In comparison, the Thermalright AXP-120-X67 operates at a slightly higher noise level of 26.1 dB(A), which, while still relatively quiet, may not meet the standards of users seeking absolute silence. If noise reduction is a top priority, the Noctua NH-L9x65 might be the better choice.
Aesthetics and RGB Lighting
Aesthetics can play a significant role in the decision-making process, especially for builds that showcase components through tempered glass panels. The Noctua NH-L9x65 features a classic brown and beige color scheme that appeals to traditionalists. However, it lacks RGB lighting, which can be a drawback for users looking to enhance their builds visually. In contrast, the Thermalright AXP-120-X67 includes ARGB lighting, allowing for customizable lighting effects, which can add a modern flair to any setup. This feature may sway users who prioritize aesthetics alongside performance.
Price Comparison
Price is a critical factor in choosing between the two coolers. The Noctua NH-L9x65 is priced at $69.95, while the Thermalright AXP-120-X67 comes in at $32.59. This price difference of about $37.36 means the Thermalright cooler is approximately 53% cheaper, making it a more budget-friendly option without sacrificing essential performance. For users on a tighter budget or those who do not require premium features, the Thermalright may represent a more appealing choice.
Compatibility
Compatibility is vital for ensuring that a cooler fits within the chosen build. The Noctua NH-L9x65 supports a range of Intel and AMD sockets, including LGA1851, LGA1700, and AM4. This extensive compatibility makes it versatile for various setups. The Thermalright AXP-120-X67 also supports a wide range of socket types, including Intel's LGA 1700 and AMD's AM4. Both coolers are suitable for most modern CPUs, but the Noctua's additional mounting options may provide an edge in certain configurations.
Which should you buy?
Choosing between the Noctua NH-L9x65 and the Thermalright AXP-120-X67 ultimately depends on your specific needs and budget. The Noctua, with its premium build quality, ultra-quiet operation, and excellent cooling performance, is ideal for users seeking reliability and low noise levels. However, it comes at a higher price. Conversely, the Thermalright AXP-120-X67 offers solid performance and modern aesthetics at a significantly lower price, making it a great value for budget-conscious consumers. If price is your primary concern, the Thermalright is the clear winner, but if you prioritize silence and build quality, the Noctua might be worth the investment.
