Overview of the Noctua NM-AM5/4-MP83 and Thermalright AXP90 X47 Black
The Noctua NM-AM5/4-MP83 is a mounting kit priced at $9.95, while the Thermalright AXP90 X47 Black CPU cooler comes in at $22.39. The significant price difference of about 55% reflects their different roles in the cooling ecosystem. The Noctua kit serves as an upgrade for existing coolers, whereas the Thermalright model is a complete low-profile CPU cooler suitable for compact builds.
Design and Build Quality
Both products showcase thoughtful design, but they cater to different needs. The Noctua NM-AM5/4-MP83 is specifically designed for AMD AM5 and AM4 sockets, offering outstanding reliability and optimal contact pressure. It utilizes the stock AMD backplate for installation, ensuring an easy setup. In contrast, the Thermalright AXP90 X47 Black has a compact design with a total height of just 47mm, making it suitable for tight spaces in ITX cases. Its all-metal platform and black nickel plating enhance durability and corrosion resistance, which may appeal to users seeking longevity in their components.
Compatibility
Compatibility is a crucial factor when choosing between these two products. The Noctua NM-AM5/4-MP83 is tailored specifically for Noctua CPU coolers that have an 83mm mounting pitch, enabling installation on AMD's latest AM5 and AM4 sockets. It is an excellent choice for users already invested in Noctua coolers. Conversely, the Thermalright AXP90 X47 Black is more versatile, supporting a wide range of Intel and AMD sockets, including Intel 115X/1200 and AMD AM4/AM5. This broader compatibility makes it a better option for users who may switch platforms in the future.
Cooling Performance
When it comes to cooling performance, the Thermalright AXP90 X47 Black is the clear winner as it is a fully-fledged CPU cooler equipped with a 92mm TL-9015B Slim PWM fan. This cooler features four 6mm heat pipes, which help in effective heat dissipation while maintaining low noise levels, rated at a maximum of 22.4 dBA. The Noctua NM-AM5/4-MP83, on the other hand, does not provide cooling by itself; it merely allows the installation of Noctua coolers on newer AMD sockets. Thus, if cooling performance is your priority, the Thermalright option is undeniably superior.
Installation Process
The Noctua NM-AM5/4-MP83 excels in simplicity during installation. Designed for straightforward application, it leverages the existing AMD backplate, which reduces the complexity often associated with mounting coolers. This ease of installation might appeal to novice builders or those looking to upgrade their systems efficiently. The Thermalright AXP90 X47 Black, while also designed for user-friendliness, does involve a bit more work as it is a standalone cooler requiring full installation. However, it includes a back plate fastener to aid in the process.
Noise Levels
Noise levels can significantly affect user experience. The Thermalright AXP90 X47 Black operates at a maximum noise level of 22.4 dBA, which is quite reasonable for a CPU cooler and should not disturb users during regular operation. The Noctua NM-AM5/4-MP83 does not generate noise on its own since it is not a cooler but merely a mounting kit. Therefore, the choice between them in terms of noise level ultimately hinges on which Noctua cooler you pair it with, as cooling solutions vary in their acoustic performance.
Price Point
Price is a decisive factor for many consumers. The Noctua NM-AM5/4-MP83 is priced at $9.95, making it a cost-effective solution for those who already own compatible Noctua coolers. In contrast, the Thermalright AXP90 X47 Black costs $22.39, which is about 55% more expensive than the Noctua kit. This price difference reflects the additional value provided by a complete cooling solution rather than just a mounting upgrade, making it essential for buyers to consider their existing setups and future needs.
Which should you buy?
Choosing between the Noctua NM-AM5/4-MP83 and the Thermalright AXP90 X47 Black ultimately depends on your specific requirements. If you are looking for a simple and budget-friendly upgrade for an existing Noctua cooler, the Noctua NM-AM5/4-MP83 at $9.95 is an excellent choice. However, if you need a compact, versatile, and effective cooling solution for a new build or a system upgrade, the Thermalright AXP90 X47 Black at $22.39 offers superior performance and compatibility.
