Price Comparison
The Noctua NH-U12S Redux is priced at C$62.95, while the Delta A40 ARGB CPU Cooler is significantly more affordable at C$19.29. This substantial price difference of C$43.66 highlights the budget-friendly appeal of the Delta A40, making it an attractive option for consumers looking to save money without compromising too much on quality. The Noctua model, however, is known for its premium build and performance, justifying its higher price tag for users who prioritise quality and efficiency over cost.
Design and Aesthetics
Both coolers showcase unique design elements, yet they target different user preferences. The Delta A40 ARGB stands out with its circular design and customizable ARGB lighting, appealing to users who desire a visually striking setup. Its mirror-like finish and dynamic streamline design enhance its aesthetic appeal. In contrast, the Noctua NH-U12S Redux maintains a more traditional and understated look, focusing on functionality with its slim 120mm size. While the NH-U12S Redux may not be as flashy, its design prioritises compatibility and ease of installation, making it a practical choice for many builds.
Performance Capability
In terms of performance, the Delta A40 ARGB can handle up to 220W power dissipation, making it capable of supporting high loads typical in gaming and creative tasks. This level of power handling ensures stable operation under pressure, which is crucial for demanding applications. The Noctua NH-U12S Redux, while it doesn’t specify a wattage limit, is designed for efficient cooling of Intel Core and AMD Ryzen processors, making it suitable for moderate overclocking and high-performance tasks. Users may find the NH-U12S Redux particularly appealing for its balance of performance and low noise levels.
Noise Levels
When it comes to noise levels, the Delta A40 ARGB operates at a maximum noise level of 29 dB(A), which is relatively quiet, especially considering its performance capabilities. The fan speed can reach up to 2000 RPM, balancing airflow and sound output effectively. The Noctua NH-U12S Redux, equipped with a quiet NF-P12 redux-1700 fan, is designed to offer full cooling performance under load while remaining near silent during idle times. Both coolers aim to minimise noise, but the Noctua may provide a slightly quieter experience under typical usage conditions.
Installation Process
Installation is straightforward for both models, but the approaches differ slightly. The Noctua NH-U12S Redux includes the SecuFirm2 mounting system, which is known for its ease of installation across various Intel and AMD sockets, including LGA1851, LGA1700, and AM4. This system is appreciated for simplifying the setup process. On the other hand, the Delta A40 ARGB provides all-metal mounting hardware, ensuring compatibility with mainstream Intel and AMD platforms, such as AM4 and LGA1200. While both coolers are user-friendly, the Noctua's mounting system may offer a more secure fit.
Thermal Paste Inclusion
The Noctua NH-U12S Redux comes with high-end NT-H1 thermal paste included in the package, which is renowned for its excellent thermal conductivity and ease of application. This addition enhances its overall value, especially for users who may not have thermal paste on hand. In contrast, the Delta A40 ARGB does not specify the inclusion of any thermal paste, meaning users may need to purchase their own, potentially adding to the overall cost. This factor could make the Noctua a more convenient option for some buyers.
Brand Reputation
Noctua is well-known for its high-quality cooling solutions, often regarded as a premium brand in the market. Their products are frequently lauded for reliability, performance, and low noise levels. The NH-U12S Redux is an extension of this reputation, representing a more affordable option without compromising on quality. On the other hand, the Delta A40 ARGB, produced by Ocypus, is less established within enthusiast circles. While it offers appealing features, its brand recognition may not match that of Noctua, making buyers more cautious about its long-term performance and reliability.
Which should you buy?
Choosing between the Noctua NH-U12S Redux and the Delta A40 ARGB CPU Cooler boils down to personal preferences and specific needs. If you are looking for a reliable, high-performance cooler with a strong brand reputation and don’t mind spending a bit more, the Noctua NH-U12S Redux is an excellent choice. Its robust design and quiet operation make it ideal for users seeking quality performance. Conversely, if budget is a major concern and you desire a cooler with aesthetic appeal, the Delta A40 ARGB offers excellent value for its price. It provides solid performance and customizable lighting, catering to gamers and creative professionals on a tighter budget. Ultimately, both products have their strengths, making them suitable for different types of users.
