Price Comparison

The Noctua NH-U12S Redux is priced at C$62.95, while the Thermalright Aqua Elite 240 V3 Liquid CPU Cooler comes in at a higher price of C$71.90. This difference of C$8.95 makes the Noctua cooler the more budget-friendly option for consumers seeking effective CPU cooling solutions. While both products promise excellent cooling capabilities, the Noctua model offers a more attractive entry point for those prioritising cost-effectiveness. For users on a tighter budget, the lower price of the NH-U12S Redux could be a decisive factor.

Cooling Performance

The Thermalright Aqua Elite 240 V3 boasts superior cooling performance due to its liquid cooling design, which typically provides more effective heat dissipation than traditional air coolers. This model features a fourth-generation pump head alongside a 240mm black aluminium fin heat sink, designed to maintain a high level of efficiency while keeping noise levels low. In contrast, the Noctua NH-U12S Redux, while still effective, operates with a slim 120mm fan. The NF-P12 redux-1700 fan promises quiet operation at idle and full cooling performance under load, but it may not match the overall cooling potential of the Thermalright's liquid system.

Design and Aesthetics

In terms of design, the Thermalright Aqua Elite 240 V3 stands out with its octagonal pump head and ARGB lighting effects, providing a visually appealing addition to any build. The lighting can sync with your motherboard for a cohesive look. On the other hand, the Noctua NH-U12S Redux focuses on functionality with a streamlined, minimalist design that prioritises compatibility over aesthetics. While the Noctua may not offer the same level of visual flair, its quality and performance reputation are well-regarded in the PC building community.

Installation Process

The installation process for both coolers is designed to be user-friendly, but they differ in complexity. The Noctua NH-U12S Redux comes with the SecuFirm2 mounting system, making it straightforward to install on various Intel and AMD sockets, including LGA115x and AM4. In comparison, the Thermalright Aqua Elite 240 V3 is also designed for easy installation but requires a bit more setup due to its AIO liquid cooler configuration. It supports a wide range of AMD and Intel sockets, but users might need to pay closer attention to the installation instructions to ensure a successful setup.

Noise Levels

When it comes to noise levels, the Noctua NH-U12S Redux is engineered for quiet operation, utilising the NF-P12 redux-1700 fan, which is known for its near-silent performance at idle. On the other hand, the Thermalright Aqua Elite 240 V3 features dual 120mm fans with a maximum noise level of 23dBA. While this is relatively quiet for a liquid cooler, it may not match the whisper-quiet performance of the Noctua model. Therefore, for users who prioritise a silent computing environment, the NH-U12S Redux may be the preferable choice.

Compatibility

Compatibility is a key consideration for CPU coolers, and both the Noctua NH-U12S Redux and Thermalright Aqua Elite 240 V3 offer extensive support for various motherboard sockets. The Noctua cooler fits most tower cases and does not overhang RAM slots, making it compatible with a wide range of builds. The Thermalright model also supports a broad array of AMD and Intel sockets, including AM4, AM5, and LGA1700. However, due to its liquid cooling design, it may require specific case dimensions to accommodate the 240mm radiator, which could limit its compatibility in tighter spaces.

Brand Reputation

Noctua is widely regarded for its high-quality cooling solutions, emphasising performance and reliability. The NH-U12S Redux is a part of its redux line, which maintains the brand's reputation while offering a more affordable option. Thermalright, while also noted for quality products, is less universally recognised than Noctua but has a loyal following among enthusiasts who appreciate its innovative designs, such as the Aqua Elite 240 V3. The choice between these brands often comes down to personal preference and past experiences with their products.

Which should you buy?

Choosing between the Noctua NH-U12S Redux and the Thermalright Aqua Elite 240 V3 ultimately depends on your specific needs and priorities. If you're looking for a reliable, cost-effective air cooler with a solid reputation for quiet operation, the NH-U12S Redux at C$62.95 is an excellent choice. However, if you require superior cooling performance and are willing to invest a bit more at C$71.90 for a liquid cooling solution with aesthetic appeal, the Thermalright Aqua Elite 240 V3 could be the better option. Consider your use case, budget, and preferences to make the best decision for your setup.
