Overview of Products
In this comparison, we will look at two different CPU cooling solutions: the Noctua NM-AM5/4-MP83 SecuFirm2 Mounting-Kit and the Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler. The Noctua kit costs $9.95, while the Thermalright cooler is priced at $19.39, making the Noctua option about 48% cheaper. Each product serves a distinct purpose, catering to specific needs within your PC build.
Design and Build Quality
The Noctua NM-AM5/4-MP83 is a mounting kit designed to enhance the installation process of compatible Noctua CPU coolers on AMD's AM5 and AM4 sockets. Notably, it uses the motherboard’s stock AMD backplate, ensuring a streamlined installation experience. The kit is renowned for its outstanding reliability and optimal contact pressure, reflecting Noctua's commitment to quality.
On the other hand, the Thermalright AXP90-X53 features a low-profile design with a height of just 53mm, which is ideal for small ITX motherboards and tight spaces. It integrates a 92mm high-performance PWM fan coupled with a pure copper base and four copper heat pipes, indicating a strong focus on effective cooling. The build quality of the Thermalright cooler emphasizes durability and efficiency, making it suitable for a range of CPU setups.
Cooling Performance
Cooling performance is a critical factor in CPU coolers, and both products have their strengths. The Thermalright AXP90-X53 is equipped with a PWM fan that operates at a maximum speed of 2700 RPM and produces a noise level of 22.4 dBA, which makes it relatively quiet for the performance it delivers. Its design allows it to handle a TDP of up to 150W, ensuring it can effectively cool high-performance CPUs.
Contrastingly, the Noctua NM-AM5/4-MP83 is not a cooler itself but rather a mounting kit that allows the installation of existing Noctua coolers. Therefore, its cooling performance is inherently tied to the Noctua cooler you pair it with. While it does not directly provide cooling, the Noctua brand is synonymous with high-quality thermal performance and reliability.
Compatibility
When it comes to compatibility, both products are designed to work seamlessly with AMD's AM4 and AM5 sockets, making them suitable for a wide range of modern processors. The Noctua NM-AM5/4-MP83 is specifically tailored for Noctua coolers, enabling a straightforward installation process that leverages the motherboard's stock backplate.
The Thermalright AXP90-X53, however, offers broader compatibility across multiple platforms, including Intel's LGA1700, LGA1851, and various other sockets. This versatility makes it a more flexible choice for users who might switch platforms or upgrade their systems in the future. The AXP90-X53 effectively caters to a wider audience, providing options for both AMD and Intel processors.
Installation Process
The installation process can make or break a CPU cooler's appeal. The Noctua NM-AM5/4-MP83 focuses on easy and straightforward installation, utilizing the motherboard’s existing backplate, which simplifies the setup. This feature is particularly beneficial for users who may not have extensive experience with hardware installation.
In contrast, the Thermalright AXP90-X53, while still designed for ease of use, requires the user to follow a manual or installation video for proper mounting. While it includes various fasteners for different platforms, the installation may be slightly more complex compared to the Noctua kit. However, once installed, users can benefit from its efficient cooling capabilities.
Noise Levels
Noise levels are an important consideration for users who prioritize a quiet computing environment. The Thermalright AXP90-X53 operates at a maximum noise level of 22.4 dBA, making it a quiet option, especially for a cooler that can handle high thermal loads. This low noise operation is particularly advantageous for users building a home theater PC or working in a noise-sensitive environment.
The Noctua NM-AM5/4-MP83 does not produce noise itself, as it is a mounting kit rather than a cooling solution. However, it is worth noting that Noctua coolers are generally known for their silent operation, and a cooler installed with this mounting kit would likely maintain that reputation.
Price Comparison
The Noctua NM-AM5/4-MP83 is priced at $9.95, while the Thermalright AXP90-X53 retails for $19.39. This makes the Noctua kit approximately 48% more affordable than the Thermalright cooler. For users on a budget or those who already own compatible Noctua coolers, the NM-AM5/4-MP83 presents a compelling value.
However, considering the Thermalright AXP90-X53’s dual-purpose functionality as both a cooler and a mounting solution, it may justify its higher price for users seeking an all-in-one product. The price difference reflects not only the products' functionalities but also their target audiences.
Which should you buy?
Choosing between the Noctua NM-AM5/4-MP83 and the Thermalright AXP90-X53 ultimately depends on your specific needs. If you are looking for a cost-effective mounting solution for an existing Noctua cooler, the NM-AM5/4-MP83 is an excellent choice, offering great value at $9.95. However, if you require a complete cooling solution that works across multiple platforms and provides efficient thermal management, the Thermalright AXP90-X53 at $19.39 is worth the investment.
