Noctua NH-L9i-17xx vs Thermalright Peerless Assassin 120 Vision MAX ARGB Black CPU Air Cooler

Overview of the Noctua NH-L9i-17xx and Thermalright Peerless Assassin 120 Vision MAX ARGB

In this comparison, we will explore the Noctua NH-L9i-17xx and the Thermalright Peerless Assassin 120 Vision MAX ARGB. The Noctua is priced at C$59.95, offering a compact solution for small form factor builds, while the Thermalright is more robust, priced at C$78.59, featuring advanced cooling technology. Both coolers cater to different user needs and preferences, making it crucial to delve into their specifications.

Cooling Performance

The Thermalright Peerless Assassin 120 Vision MAX ARGB boasts superior cooling performance thanks to its dual-tower design and high-speed fans that can reach up to 2150 RPM. The six pure copper heat pipes ensure optimal thermal transfer from the CPU, making it a strong contender for high-performance applications. In contrast, the Noctua NH-L9i-17xx, while effective, is primarily designed for compact builds. It features a slim 37mm height and an NF-A9x14 92mm fan, which provides adequate cooling for moderate heat loads but may not match the raw performance of the Thermalright under heavy workloads.

Design and Aesthetics

When it comes to design, the Thermalright Peerless Assassin 120 Vision MAX ARGB stands out with its dual-tower configuration and a magnetically attached top cover that features a 5-inch IPS LCD screen. This visually appealing design not only enhances aesthetics but also provides useful information about system performance. On the other hand, the Noctua NH-L9i-17xx embodies a more utilitarian approach with its compact footprint, making it ideal for HTPC and SFF cases where space is at a premium. While the Noctua does not focus on RGB lighting or flashy displays, it offers a clean and professional look that appeals to many users.

Size and Compatibility

The Noctua NH-L9i-17xx is specifically tailored for small form factor builds, measuring just 37mm in height. This allows it to fit seamlessly into compact enclosures, ensuring 100% compatibility with RAM and PCIe slots on all ITX, Micro-ATX, and ATX LGA1700 or LGA1851 motherboards. In contrast, the Thermalright Peerless Assassin 120 Vision MAX ARGB measures 164mm in height, making it suitable for standard ATX cases, but it may not fit in smaller builds. Users with limited space may find the Noctua to be the better option due to its compact design.

Installation Process

Both coolers offer straightforward installation processes, but they cater to different user experiences. The Noctua NH-L9i-17xx comes with a SecuFirm2 mounting system that simplifies installation on Intel LGA1700 and LGA1851 CPUs, making it a user-friendly option for beginners. The Thermalright Peerless Assassin 120 Vision MAX ARGB also aims for ease of installation but may require more consideration due to its larger size and dual-tower design. Users who prioritize quick and easy installation may lean towards the Noctua cooler.

Noise Levels

The Noctua NH-L9i-17xx is designed for whisper-quiet operation, thanks in part to its PWM fan control, which adjusts the speed based on load. This makes it an excellent choice for users who value silence in their systems. While the Thermalright Peerless Assassin 120 Vision MAX ARGB operates at a maximum noise level of ≤27 dB(A), it is important to note that its dual fans may produce more noise under heavy load compared to the Noctua. Users seeking a quieter cooling solution might prefer the Noctua for its low-noise operation.

Thermal Paste

Both coolers come with high-quality thermal paste to ensure optimal heat transfer. The Noctua NH-L9i-17xx includes the renowned NT-H1 thermal paste, known for its excellent thermal conductivity and ease of application. The Thermalright Peerless Assassin 120 Vision MAX ARGB does not specify the thermal paste included, but the presence of advanced heat pipe technology suggests a focus on efficient thermal management. For users who prioritize ease of use, the inclusion of thermal paste with the Noctua cooler might be a decisive factor.

Price Consideration

The Noctua NH-L9i-17xx is priced at C$59.95, making it a budget-friendly option for users looking for reliable cooling in compact builds. Conversely, the Thermalright Peerless Assassin 120 Vision MAX ARGB is priced at C$78.59, reflecting its more advanced cooling capabilities and added features like RGB lighting and an LCD display. Users should weigh their budget against the specific needs of their builds, as the Noctua offers a more economical choice without compromising on quality.

Which should you buy?

Choosing between the Noctua NH-L9i-17xx and the Thermalright Peerless Assassin 120 Vision MAX ARGB ultimately depends on your specific needs. If you require a compact, efficient solution for small form factor builds, the Noctua NH-L9i-17xx is the clear winner, offering excellent compatibility and a budget-friendly price. However, if you are looking for superior cooling performance and are willing to invest a bit more for advanced features, the Thermalright Peerless Assassin 120 Vision MAX ARGB is an outstanding option, especially for users with standard ATX cases. Assess your requirements carefully to make the best choice for your system.
