Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler vs Noctua NH-U12S redux

Overview of Thermalright AXP90-X47 and Noctua NH-U12S redux

The Thermalright AXP90-X47 and the Noctua NH-U12S redux are both notable CPU coolers, but they cater to different user needs. The AXP90-X47 is priced at £41.90, making it an attractive option for budget-conscious users seeking low-profile cooling solutions. In contrast, the NH-U12S redux, with a price tag of £65.68, offers a more extensive cooling capability, albeit at a higher cost.

Design and Dimensions

When it comes to design, the Thermalright AXP90-X47 stands out with its low-profile dimensions of 94.5×95×47mm, making it ideal for compact builds such as HTPCs and ITX systems. This minimal height allows for compatibility with smaller cases without sacrificing performance. On the other hand, the Noctua NH-U12S redux features a slim 120mm design that fits most tower cases, with a height of 158mm. While the NH-U12S redux is taller, it does not overhang RAM slots or block PCIe slots, ensuring versatility in larger builds.

Cooling Performance

In terms of cooling performance, the Thermalright AXP90-X47 features a maximum air volume of 42.58 CFM and operates at a noise level of 22.4 dB(A). This makes it a quiet option for users who prioritise low noise levels in their builds. Conversely, the Noctua NH-U12S redux utilises a 120mm fan that is designed for quiet operation, maintaining near-silent performance at idle while delivering robust cooling under load. This dual nature may appeal more to users who require high performance without noise distractions.

Fan Technology

Both coolers employ advanced fan technology, but they have different approaches. The AXP90-X47 comes with a TL-9015R fan that operates at a maximum speed of 2700 RPM, which is beneficial for achieving higher airflow. However, it is important to note that this speed may lead to increased noise levels under heavy loads. The NH-U12S redux, on the other hand, features the NF-P12 redux-1700 fan, which also utilises PWM for automatic speed control. This allows it to adapt its speed based on the cooling requirements, maintaining a balance between performance and noise.

Installation and Compatibility

Installation is straightforward for both coolers, but they cater to different platforms. The Thermalright AXP90-X47 supports various Intel sockets, including LGA 1700 and LGA 1200, as well as AMD AM4 and AM5. This broad compatibility makes it suitable for a range of recent builds. The Noctua NH-U12S redux also supports a wide array of Intel and AMD sockets, including the latest AM5 and LGA 1700, ensuring its relevance in contemporary systems. Both coolers come with high-quality thermal paste, enhancing their value proposition for users looking to maximise cooling efficiency.

Build Quality and Aesthetics

Thermalright is known for its functional designs, and the AXP90-X47 showcases this with its pure copper radiator, which enhances heat dissipation and corrosion resistance. The plating anti-oxidation protective layer is an added benefit, making it durable over time. Meanwhile, Noctua is renowned for its premium build quality, and the NH-U12S redux is no exception. It is designed with aesthetics in mind, featuring a sleek finish that can blend well with most builds, appealing to users who value visual consistency alongside performance.

Price and Value

Price is a crucial factor when choosing between these two coolers. The Thermalright AXP90-X47 is priced at £41.90, offering a cost-effective solution without compromising on essential cooling features. In contrast, the Noctua NH-U12S redux, at £65.68, justifies its higher price through advanced cooling capabilities, superior build quality, and lower noise levels. Users must consider whether the additional investment in the NH-U12S redux aligns with their performance needs and budget.

Which should you buy?

Choosing between the Thermalright AXP90-X47 and the Noctua NH-U12S redux ultimately depends on your specific requirements. If you are looking for a budget-friendly, low-profile cooler that performs well in compact builds, the AXP90-X47 at £41.90 is a solid choice. However, if you require superior cooling performance and flexibility in larger cases, the NH-U12S redux is worth the extra £23.78. Both coolers offer distinct advantages, making them suitable for different user scenarios.
