Noctua NH-U12S Redux vs Thermalright AXP90 X47 Full Low Profile CPU Cooler

Overview of the Noctua NH-U12S Redux and Thermalright AXP90 X47

The Noctua NH-U12S Redux is priced at C$62.95, while the Thermalright AXP90 X47 is more affordable at C$43.39. Both CPU coolers offer distinct features appealing to different user needs, making it essential to evaluate their specifications closely.

Noctua’s NH-U12S Redux belongs to a streamlined, cost-effective line while retaining the high-quality design that Noctua is known for. It features a slim 120mm size, ensuring compatibility with most tower cases and does not impede RAM slots or PCIe. In contrast, the Thermalright AXP90 X47 is designed as a low-profile cooler with a height of just 47mm, making it ideal for compact builds like HTPCs and ITX systems.

Cooling Performance

In terms of cooling performance, the Noctua NH-U12S Redux stands out with its NF-P12 redux-1700 120mm fan, which is designed for automatic speed control. This allows it to deliver excellent cooling performance under load while maintaining near-silent operation at idle. The fan's efficiency makes it suitable for high-performance CPUs, particularly Intel Core and AMD Ryzen processors.

On the other hand, the Thermalright AXP90 X47 employs a 92mm PWM fan, which also offers automatic temperature control. With a maximum speed of 2700 RPM, it generates an air pressure of 1.33mmH2O and operates at a noise level of 22.4 dB(A). While it may not match the size of Noctua's fan, its design is optimised for low-profile applications, ensuring adequate cooling even in tight spaces.

Compatibility

Compatibility is crucial when selecting a CPU cooler, and both models cater to a range of CPU sockets. The Noctua NH-U12S Redux is versatile, supporting a variety of Intel and AMD platforms, including LGA1851, LGA1700, and AM5. This broad compatibility makes it a smart choice for those who might upgrade their CPU in the future.

Similarly, the Thermalright AXP90 X47 supports an extensive list of CPU sockets, including Intel LGA1700 and AMD AM4/AM5. This feature allows users to install the cooler across different generations of CPUs without worrying about compatibility issues. However, the Noctua's broader socket support might provide a slight edge for users with a wider range of hardware options.

Installation Process

The installation process of a CPU cooler can greatly affect user experience. The Noctua NH-U12S Redux comes with the SecuFirm2 mounting system, which is noted for its ease of installation across various socket types. This system simplifies the mounting process, reducing the chances of improper installation.

Conversely, the Thermalright AXP90 X47 also includes a manual and installation video for guidance. Its design includes metal mounting fasteners tailored for different platforms, ensuring a straightforward setup. While both coolers offer user-friendly installation, the Noctua’s established reputation for quality installation systems may provide additional reassurance to users.

Noise Levels

Noise levels are a significant consideration for many PC builders. The Noctua NH-U12S Redux operates near silently at idle, which is a critical feature for users who prioritize a quiet computing environment. Its fan is engineered to balance performance and noise, ensuring that it remains unobtrusive under normal use.

The Thermalright AXP90 X47, while also designed for quiet operation, has a slightly higher maximum noise level of 22.4 dB(A) at full speed. Although this is still relatively quiet, users seeking the utmost silence may prefer the Noctua solution. Therefore, in scenarios requiring minimal noise, the NH-U12S Redux may be the better choice.

Build Quality and Aesthetics

Build quality and aesthetics can influence consumers’ choices, and both coolers are designed with durability in mind. The Noctua NH-U12S Redux is renowned for its premium construction and materials, ensuring long-term reliability. Its sleek design complements most builds, and its neutral colour scheme is often praised for blending well with various components.

On the other hand, the Thermalright AXP90 X47 features a compact and functional design optimised for low-profile setups. Constructed with pure copper, it enhances both durability and heat transfer efficiency. While it may not have the same aesthetic appeal as the Noctua, its practical design serves its purpose well in smaller form factors.

Price Comparison

Price is often a decisive factor in product selection. The Noctua NH-U12S Redux is priced at C$62.95, reflecting its premium positioning and quality. This price point may deter budget-conscious buyers, but it is justified by its performance and reputation.

In contrast, the Thermalright AXP90 X47 is more budget-friendly at C$43.39. This makes it an attractive option for users looking for an efficient cooler without breaking the bank. The price difference of C$19.56 could be a significant factor for those building a system on a tighter budget, making the Thermalright a compelling choice.

Which should you buy?

When choosing between the Noctua NH-U12S Redux and the Thermalright AXP90 X47, it ultimately depends on your specific needs and preferences. If you require a cooler that provides excellent performance, silent operation, and broad compatibility, the Noctua NH-U12S Redux is the superior option despite its higher price. Conversely, if you're seeking a more affordable solution that works well in compact builds, the Thermalright AXP90 X47 offers great value and adequate performance for smaller setups. Each cooler excels in its niche, so consider your priorities when making your choice.
