Dimension comparison
Overview of the Noctua NH-U12A chromax.Black and Thermalright AXP90 X47
When comparing the Noctua NH-U12A chromax.Black and the Thermalright AXP90 X47, the price difference is significant. The Noctua is priced at $134.95, while the Thermalright is considerably cheaper at $33.99, making it about 75% less expensive than its counterpart. However, the price alone doesn’t determine the best choice for your CPU cooling needs.
Design and Aesthetics
The Noctua NH-U12A chromax.Black features a sleek all-black design that enhances various computer builds. Its single-tower design is 158mm tall, ensuring it fits most tower cases without obstructing RAM or PCIe slots. In contrast, the Thermalright AXP90 X47 boasts an ultra-compact low-profile design with a total height of just 47mm. This makes it suitable for smaller form factor builds, particularly for those who need to conserve space. Both products cater to different design aesthetics and requirements, making it essential to consider your case’s dimensions before making a choice.
Cooling Performance
Cooling performance is a crucial aspect of any CPU cooler. The Noctua NH-U12A chromax.Black features dual NF-A12x25 120mm fans, which deliver exceptional cooling efficiency while maintaining low noise levels. This dual-fan setup ensures high performance under load and whisper-quiet operation at idle. On the other hand, the Thermalright AXP90 X47 utilizes a 92mm PWM fan alongside four heat pipes for efficient heat transfer. Although it is a low-profile cooler, it offers a noise level of just 22.4 dB(A), making it quiet during operation. Both coolers provide excellent thermal performance, but the Noctua may have the edge in demanding scenarios due to its larger fan size and dual-fan setup.
Compatibility
Compatibility is a vital factor when choosing a CPU cooler. The Noctua NH-U12A chromax.Black supports a wide range of Intel and AMD sockets, including LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4. This extensive compatibility makes it a versatile choice for various builds. In comparison, the Thermalright AXP90 X47 is also compatible with multiple platforms, including Intel LGA 1150, 1151, 1200, and 1700, as well as AMD AM4 and AM5. While both coolers offer solid compatibility, the Noctua has a slight advantage with its broader range of supported sockets.
Installation Process
When it comes to installation, the Noctua NH-U12A chromax.Black includes the SecuFirm2 mounting system, which simplifies the process for users. This user-friendly system ensures a secure fit on various Intel and AMD sockets. The Thermalright AXP90 X47 also features a user-friendly design, making installation straightforward. However, specific details about its mounting system are less emphasized compared to the Noctua’s offering. For those who value installation ease, the Noctua may be the more reassuring option due to its established reputation for quality.
Noise Levels
Noise levels can significantly affect the user experience, especially in quiet environments. The Noctua NH-U12A chromax.Black is engineered for low-noise operation, thanks to its dual-state-of-the-art fans that adjust speeds automatically. While specific decibel ratings for the Noctua are not provided, the reputation for whisper-quiet performance is well-established. Conversely, the Thermalright AXP90 X47 operates at a noise level of 22.4 dB(A), which is relatively quiet, especially for a low-profile cooler. If noise levels are a primary concern, both coolers are designed to minimize sound, but the Noctua may still offer a quieter experience under load due to its advanced fan technology.
Build Quality and Warranty
Build quality is an important consideration for durability and reliability. The Noctua NH-U12A chromax.Black is backed by a 6-year manufacturer’s warranty, reflecting the brand's confidence in its product. Its premium heatsink design has won over 100 awards and recommendations, further solidifying its reputation. The Thermalright AXP90 X47, while also well-constructed, does not specify a warranty period, which could be a point of concern for some users. The superior warranty and recognition associated with the Noctua cooler may sway buyers looking for longevity and support.
Which should you buy?
When deciding between the Noctua NH-U12A chromax.Black and the Thermalright AXP90 X47, it ultimately depends on your specific needs. If you require a high-performance cooler with a proven track record, extensive compatibility, and a quiet operation, the Noctua NH-U12A chromax.Black is worth the investment at $134.95. However, if you are working with a compact build and need a cost-effective solution, the Thermalright AXP90 X47 provides excellent value at just $33.99. Each cooler has its strengths, making the final choice contingent upon your budget and specific usage requirements.
