Overview of the Products

In this comparison, we will look at two distinct CPU coolers: the Noctua NM-AM5/4-MP83 SecuFirm2 Mounting Kit and the Thermalright AXP90 X36 Low Profile ITX CPU Cooler. The Noctua cooler is priced at $9.95, making it a budget-friendly option, while the Thermalright cooler is priced at $20.39, approximately 105% more expensive. Each product targets different needs within the CPU cooling market, with Noctua focusing on mounting solutions and Thermalright providing a full cooling system.

Design and Build Quality

The Noctua NM-AM5/4-MP83 is a mounting upgrade kit specifically designed for Noctua CPU coolers, allowing compatibility with AMD’s AM5 and AM4 sockets. It features a reliable design that leverages the motherboard's stock AMD backplate for easy installation. On the other hand, the Thermalright AXP90 X36 boasts a compact, all-metal platform with a height of just 36mm. This design emphasizes low-profile adaptability, making it suitable for small form-factor builds. With premium construction and nickel plating for corrosion resistance, both products promise durability, but they cater to different installation scenarios.

Compatibility

Compatibility is a crucial factor when choosing CPU cooling solutions. The Noctua NM-AM5/4-MP83 is tailored for Noctua CPU coolers, enabling their installation on AMD Ryzen 5, Ryzen 7, and Ryzen 9 processors. It specifically accommodates the AM5 and AM4 sockets, ensuring a perfect fit for users with compatible Noctua coolers. Conversely, the Thermalright AXP90 X36 supports multiple platforms, including Intel’s LGA1150, LGA1151, LGA1200, LGA1700, and LGA1851, as well as AMD’s AM4 and AM5. This broader compatibility makes the Thermalright option more versatile for varied builds.

Cooling Performance

In terms of cooling performance, the Thermalright AXP90 X36 stands out with its advanced design featuring four 6mm AGHP heatpipes and a slim PWM fan capable of generating noise levels as low as 22.4 dBA. This ensures efficient heat dissipation while maintaining a quiet operation, which is essential for users seeking a silent computing experience. The Noctua NM-AM5/4-MP83 does not provide cooling performance directly, as it is a mounting kit rather than a cooler itself. Therefore, the effectiveness of Noctua’s coolers will depend on the model used in conjunction with this mounting kit.

Installation Process

The installation process varies significantly between the two products. The Noctua NM-AM5/4-MP83 is designed for straightforward installation, utilizing the existing AMD backplate to simplify the setup. This user-friendly approach makes it accessible for all levels of PC builders. In contrast, the Thermalright AXP90 X36, while compact and well-designed, may require more consideration during installation due to its low-profile constraints and the need for a compatible motherboard and backplate. For users seeking a hassle-free installation, Noctua's mounting kit may be the preferable choice.

Price Comparison

When comparing prices, the Noctua NM-AM5/4-MP83 is significantly more affordable at $9.95, making it a budget-conscious option for those who already own compatible Noctua coolers. In contrast, the Thermalright AXP90 X36 is priced at $20.39, which is about 105% higher than Noctua's offering. This price difference could influence buyers, particularly those on a tight budget or those who require only a mounting solution rather than a full cooler.

User Considerations

For users who own compatible Noctua coolers, the NM-AM5/4-MP83 is an essential product that facilitates the transition to AMD’s latest socket designs. Its outstanding reliability and optimal contact pressure make it a valuable addition to any Noctua cooler setup. However, for those building a new system or seeking comprehensive cooling solutions, the Thermalright AXP90 X36 offers a complete package with its low-profile design and cross-platform compatibility. The choice ultimately depends on whether the user needs a mounting kit or a full cooling solution.

Which should you buy?

Choosing between the Noctua NM-AM5/4-MP83 and the Thermalright AXP90 X36 depends on your specific needs. If you already have a Noctua cooler and are looking for an affordable way to mount it on an AMD AM5 or AM4 socket, the Noctua mounting kit at $9.95 is an excellent choice. However, if you require a complete cooling solution that supports multiple platforms and offers low-profile advantages, the Thermalright cooler at $20.39 is worth the investment. Consider your current setup and future needs carefully to make the best decision for your CPU cooling requirements.
