Overview of the Thermalright Peerless Assassin 120 and Noctua NH-D15 chromax.Black
The Thermalright Peerless Assassin 120 is priced at C$51.39, while the Noctua NH-D15 chromax.Black is significantly higher at C$174.95. This price difference sets the stage for a comparison of their cooling performance, design, and user experience.
The Thermalright model boasts an effective heat dissipation area of 9600 cm² and features a dual-tower design with two PWM fans. In contrast, the Noctua NH-D15 chromax.Black is celebrated for its premium heatsink design and dual 140mm fans, making it a strong contender for users seeking high performance and low noise levels.
Cooling Performance
When it comes to cooling performance, the Noctua NH-D15 chromax.Black is a standout, offering capabilities on par with many all-in-one water coolers. Its extra-wide dual-tower design incorporates six heat pipes, which allows it to efficiently manage temperatures, even under load. This makes it particularly appealing for overclockers and users who demand silent operation.
On the other hand, the Thermalright Peerless Assassin 120, with its dual tower cooling and six heat pipes, also promises strong performance. It has a TDP rating of 245W, indicating it can handle substantial thermal loads. However, in extensive cooling tests, the Noctua has received over 300 awards and recommendations, showcasing its reliability and effectiveness in real-world scenarios.
Fan Noise Levels
Noise levels are critical for many users, especially those building quiet systems. The Noctua NH-D15 chromax.Black excels in this area, featuring renowned NF-A15 140mm fans designed for whisper-quiet operation. With Low-Noise Adaptors and PWM control, the fans adjust speed automatically, providing full cooling performance when needed while remaining silent at idle.
In comparison, the Thermalright Peerless Assassin 120 has a noise level specification of ≤25.6 dB(A). While this is relatively quiet, the Noctua's design is built specifically for minimal noise output, making it a better choice for silent computing environments.
Aesthetics and Design
Aesthetics play a significant role in many users' purchasing decisions. The Noctua NH-D15 chromax.Black features an elegant all-black design that complements various builds and colour schemes, making it visually appealing for those who prioritize aesthetics alongside performance.
Conversely, the Thermalright Peerless Assassin 120 has a striking white finish with ARGB lighting effects. Its colourful illumination can add a visually dynamic element to a gaming rig but may not appeal to users looking for a more understated or professional appearance. Ultimately, design preferences will influence which cooler suits a user's style best.
