Dimension comparison
Design and Aesthetics
The Thermalright Peerless Assassin 120 SE V2 boasts a compact design, while the Noctua NH-D15 chromax.Black features a broader dual-tower setup. The Thermalright model measures 125mm x 135mm x 155mm, making it suitable for various builds without taking up excessive space. In contrast, the Noctua's extra-wide design allows for superior cooling efficiency, and its all-black aesthetic enhances compatibility with numerous colour schemes. The NH-D15 has received over 300 awards for its performance, making it a standout choice for users who prioritize both form and function in their cooling solutions.
Cooling Performance
In terms of thermal management, the Noctua NH-D15 excels with its dual-fan configuration and six heat pipes, providing exceptional cooling capabilities. The Thermalright Peerless Assassin 120 SE V2, equipped with dual thickened PWM fans, offers a maximum airflow of 88.19 CFM at a noise level of 29.5 dB(A). While the Thermalright maintains solid performance with a thermal design power (TDP) rating of 265W, the NH-D15 competes closely, often delivering cooling performance comparable to some all-in-one water coolers. This makes the Noctua a top choice for overclockers and users who demand peak performance from their CPU coolers.
Noise Levels
When it comes to noise levels, the Thermalright Peerless Assassin operates at a maximum of 29.5 dB(A), which is relatively quiet for a cooling fan. On the other hand, the Noctua NH-D15 is designed with Low-Noise Adaptors, allowing it to maintain whisper-quiet operation at idle while providing full cooling performance under load. This makes the NH-D15 particularly appealing for silent enthusiasts who want top-tier cooling without audible disturbance. The advanced engineering of both products ensures that users can enjoy a quiet computing experience.
Installation and Compatibility
Both the Thermalright Peerless Assassin and the Noctua NH-D15 are designed with user-friendly installation in mind. The Thermalright model comes with metal fasteners compatible with Intel LGA 1851/1700/1200/115X and AMD AM4/AM5 platforms, allowing for versatile use across different systems. The Noctua NH-D15 also supports a wide range of Intel and AMD sockets, including LGA1851, LGA1700, and AM4, and includes a SecuFirm2 mounting system for easy setup. The ease of installation for both coolers is a significant advantage, making them accessible for users of varying expertise levels.
Thermal Paste and Accessories
The inclusion of high-quality thermal paste can significantly affect cooling performance. The Noctua NH-D15 comes bundled with NT-H1 thermal paste, well-regarded for its thermal conductivity and ease of application. In contrast, the Thermalright Peerless Assassin does not mention any included thermal paste but focuses on its advanced heat pipe technology and efficient airflow. This difference might influence users who prefer a complete package that includes all necessary accessories for optimal thermal performance.
Price Comparison
There is a notable price difference between the two coolers, with the Thermalright Peerless Assassin retailing at C$54.90 and the Noctua NH-D15 priced significantly higher at C$174.95. This considerable gap may affect purchasing decisions, especially for budget-conscious consumers. While the Thermalright offers excellent value for its performance, the Noctua's higher price is justified by its award-winning design and superior cooling efficiency, making it a premium option for those willing to invest more in their cooling solution.
Brand Reputation and Support
Brand reputation plays a crucial role in product selection, and both Thermalright and Noctua have established themselves in the CPU cooler market. Noctua is renowned for its high-quality products, backed by a six-year manufacturer's warranty, which adds an extra layer of confidence for consumers. Thermalright, while respected, does not mention a warranty period in the available data. This could influence buyers who prioritize long-term support and reliability in their cooling solutions.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Noctua NH-D15 chromax.Black ultimately depends on your specific needs and budget. If you are seeking an affordable, effective cooling solution with solid performance, the Thermalright Peerless Assassin is an excellent choice at C$54.90. However, if you are looking for top-tier cooling performance, minimal noise, and a premium build quality, the Noctua NH-D15, priced at C$174.95, is worth the investment. Consider your system's requirements, your budget, and whether you value aesthetics and noise levels when making your decision.
