Overview of the Thermalright Peerless Assassin 120 Digital ARGB Black and Noctua NH-U12A chromax.Black
When comparing the Thermalright Peerless Assassin 120 Digital ARGB Black and the Noctua NH-U12A chromax.Black, there are significant differences in design, performance, and pricing. The Thermalright model is priced at C$62.90, making it significantly more affordable than the Noctua, which retails for C$159.95. This price disparity invites a closer look at what each cooler offers in terms of features and performance.
Design and Aesthetics
The Thermalright Peerless Assassin 120 features a dual-tower design with a sleek black finish and a digital display board. Its height is 162mm, making it compatible with most ATX chassis. This model includes a magnetic top cover to enhance its aesthetic appeal. In contrast, the Noctua NH-U12A chromax.Black sports a more classic look with an all-black design that complements various colour schemes. Standing at 158mm tall, it is designed to avoid obstructing RAM slots or PCIe on most motherboards. While both coolers offer an attractive design, the Thermalright’s digital elements may appeal more to those seeking modern aesthetics.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 120 is equipped with dual fans that operate at a maximum speed of 1850 RPM, delivering an impressive air volume of 88.89 CFM. This ensures efficient heat dissipation, especially under heavy loads. On the other hand, the Noctua NH-U12A features dual NF-A12x25 120mm fans that are renowned for their quiet operation, thanks to Low-Noise Adaptors and PWM for automatic speed control. While the exact CFM for the Noctua fans isn't specified, they are designed for top-tier performance in a 120mm size. Both coolers excel in cooling, but the Thermalright offers higher air volume at maximum speed.
Noise Levels
Noise levels are critical for users who value a quiet computing environment. The Thermalright Peerless Assassin 120 operates at a noise level of ≤25.6 dB(A), which is relatively quiet given its performance specifications. In comparison, the Noctua NH-U12A is designed to be whisper quiet at idle while still providing full cooling performance under load, though specific noise levels are not detailed. Given the Thermalright's specified noise level, it may be a better choice for users who prioritize silence during operation.
Installation and Compatibility
Both coolers are designed for ease of installation and compatibility with a variety of systems. The Thermalright Peerless Assassin 120 includes a 4PIN PWM fan power supply interface and has a height that fits most mainstream ATX cases comfortably. The Noctua NH-U12A comes with the SecuFirm2 mounting system, which allows for straightforward installation on various Intel and AMD sockets. It is particularly noted for its compatibility with a wide range of motherboards, including LGA1700 and AM4. While both coolers are user-friendly, the Noctua may offer a slight edge in terms of broader compatibility.
Thermal Paste and Accessories
The Thermalright Peerless Assassin 120 does not specify whether thermal paste is included, which is an important consideration for potential buyers. Conversely, the Noctua NH-U12A comes with high-end NT-H1 thermal paste, ensuring optimal thermal conductivity right out of the box. This inclusion adds value to the Noctua, particularly for users who might not have high-quality thermal paste readily available.
Brand Reputation
Brand reputation plays a crucial role in consumer choices. Thermalright has established itself as a competitive player in the cooling market, but Noctua is widely regarded for its premium quality and reliability, boasting over 100 awards and recommendations from international hardware websites. The Noctua NH-U12A is backed by a 6-year manufacturer’s warranty, further solidifying trust in its performance and longevity. This strong reputation may justify the higher price point for users looking for a dependable cooling solution.
Value for Money
The Thermalright Peerless Assassin 120 offers exceptional value at C$62.90, especially for users on a budget who still want reliable cooling performance. Conversely, the Noctua NH-U12A, priced at C$159.95, targets users who prioritize premium quality and performance. While the Noctua is significantly more expensive, it provides features such as a renowned design, quieter operation, and high-quality thermal paste. Ultimately, the choice depends on whether the user values cost-effectiveness or is willing to invest in a higher-end product.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black and the Noctua NH-U12A chromax.Black boils down to individual needs and budget. If you are looking for an affordable option with solid performance, the Thermalright offers excellent value at C$62.90, particularly with its strong cooling capabilities and modern design. However, if you are willing to invest in a premium product that has a proven track record of performance, quiet operation, and high-quality accessories, the Noctua NH-U12A at C$159.95 is the superior choice. Ultimately, your decision should align with your cooling requirements and financial considerations.
