Noctua NH-U9S chromax.Black, vs Thermalrlght Peerless Assassin 120 SE CPU Air

Overview of Noctua NH-U9S chromax.Black and Thermalrlght Peerless Assassin 120 SE

The Noctua NH-U9S chromax.Black is a compact and efficient cooler, priced at $74.95, while the Thermalrlght Peerless Assassin 120 SE is a more budget-friendly option at $32.90. This price difference makes the Thermalrlght cooler about 56% cheaper than the Noctua cooler. Both products cater to different needs, with the Noctua focusing on premium performance in a smaller form factor and the Thermalrlght designed for more extensive cooling capabilities at a lower price point.

Design and Build Quality

The Noctua NH-U9S chromax.Black features a sleek, all-black design that blends seamlessly with various build aesthetics, emphasizing its premium quality. It includes a renowned NF-A9 92mm fan known for whisper-quiet operation and superior cooling performance. In contrast, the Thermalrlght Peerless Assassin 120 SE is characterized by its dual 120mm fans and a unique offset asymmetric layout. This design allows for better motherboard and graphics card compatibility while still being aesthetically pleasing with a brushed black top cover. Both coolers showcase high-quality materials, but Noctua leans toward a more refined finish.

Cooling Performance

The Noctua NH-U9S chromax.Black is noted for its efficient cooling performance, maintaining low noise levels, particularly under load, thanks to its PWM fan technology. This cooler is ideal for smaller cases and offers compatibility with various CPU sockets, including Intel's LGA1700 and AMD's AM4. On the other hand, the Thermalrlght Peerless Assassin 120 SE utilizes six heat pipes and dual high-performance fans to deliver superior airflow, achieving a maximum airflow rating of 66.17 CFM. With a rated noise level of 25.6 dB(A), it strikes a balance between performance and sound output, catering to gamers and PC enthusiasts looking for effective cooling solutions.

Compatibility

The Noctua NH-U9S chromax.Black is designed with a compact 92mm size, making it suitable for most tower cases without overhanging RAM slots or blocking PCIe slots. Its compatibility extends to multiple Intel and AMD sockets, ensuring it can fit a wide range of systems. Conversely, the Thermalrlght Peerless Assassin 120 SE supports a broader range of socket types, including Intel’s LGA1700 and AMD’s AM4/AM5, while its larger dimensions may limit case compatibility. However, its design allows for better heat dissipation, making it a solid choice for larger builds.

Installation Process

Both coolers are designed for easy installation, but they approach it differently. The Noctua NH-U9S chromax.Black comes with the SecuFirm2 mounting system that simplifies the installation process across a range of socket types, making it user-friendly for those who may not be experienced in building PCs. The Thermalrlght Peerless Assassin 120 SE also features an SS2 installation system, but it requires users to utilize their motherboard's built-in backplate for AM4 and AM5 installations, which may pose a slight inconvenience for some users. Overall, both options are relatively straightforward to install, but Noctua may have a slight edge in user-friendliness.

Noise Levels

Noise output is a crucial factor for many PC builders, especially those who prioritize a quiet computing environment. The Noctua NH-U9S chromax.Black is designed to operate at whisper-quiet levels, even under load, thanks to its PWM technology that adjusts fan speeds automatically. This makes it an excellent choice for those who are sensitive to noise. The Thermalrlght Peerless Assassin 120 SE, while also relatively quiet with a maximum noise level of 25.6 dB(A), may not match the low noise performance of Noctua's offering. For users who prioritize silence, the Noctua may be the better option.

Price Comparison

The Noctua NH-U9S chromax.Black is priced at $74.95, while the Thermalrlght Peerless Assassin 120 SE is significantly more affordable at $32.90. This represents a price difference of about 56%, making the Thermalrlght a more attractive choice for budget-conscious buyers. However, potential buyers should consider that the Noctua cooler offers a premium build and quieter operation, which may justify its higher price for some users. Ultimately, the choice may come down to whether one values performance and quiet operation over cost.

Which should you buy?

Choosing between the Noctua NH-U9S chromax.Black and the Thermalrlght Peerless Assassin 120 SE largely depends on your specific needs and budget. If you require a compact, high-performance cooler with award-winning quiet operation, the Noctua is worth the investment at $74.95. Alternatively, if you're looking for an effective cooling solution at a significantly lower price of $32.90, the Thermalrlght provides excellent value with good performance and compatibility. Ultimately, both coolers have their strengths, so your decision should align with your performance needs and budget constraints.
