Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler vs Noctua NH-L9i-17xx

Price Comparison

When considering price, the Thermalright Peerless Assassin 120 SE ARGB is significantly more budget-friendly at C$46.90 compared to the Noctua NH-L9i-17xx, which is priced at C$59.95. This difference of C$13.05 makes the Thermalright option a more appealing choice for those looking to save money while still acquiring an effective CPU cooler. Both products are well-regarded in the market, but the Thermalright offers a more attractive entry point for consumers.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin boasts a TDP (thermal design power) rating of 120 to 245W, making it suitable for a wide range of CPU loads. It features a robust design with six heat pipes and dual fans that can achieve a maximum airflow of 66.17 CFM. The Noctua NH-L9i-17xx, while compact at only 37mm in height, is designed for moderate heat loads and is particularly effective for smaller systems. It uses a single NF-A9x14 fan, which is renowned for its low noise levels. Thus, while the Thermalright may offer higher maximum performance, the Noctua excels in quieter operation and space efficiency.

Size and Compatibility

The Thermalright Peerless Assassin measures 125(L) x 135(W) x 155(H) mm, allowing it to fit in a variety of cases while supporting multiple CPU socket types, including Intel's LGA 1700 and AMD AM4. In contrast, the Noctua NH-L9i-17xx is specifically designed to fit compact HTPC and small form factor cases, measuring only 37mm in height. Its tailored footprint ensures that it maintains 100% compatibility with RAM and PCIe slots on all compatible motherboards. Therefore, if space is a constraint, the Noctua is the clear winner, but for broader compatibility across various setups, the Thermalright is more versatile.

Installation Process

Both CPU coolers come with mounting systems designed for easy installation, but they differ in their approaches. The Thermalright Peerless Assassin includes metal fasteners that are compatible with Intel and AMD platforms, aimed at achieving a straightforward installation process. On the other hand, the Noctua NH-L9i-17xx features the SecuFirm2 mounting system, which is well-regarded for its user-friendliness and reliability. Additionally, it comes with high-end NT-H1 thermal paste, making it easier for users to achieve optimal thermal conductivity right out of the box. While both products offer ease of installation, Noctua’s comprehensive package gives it a slight edge in this category.

Noise Levels

In terms of noise, the Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a cooler with dual fans and higher airflow. The Noctua NH-L9i-17xx, however, is known for its exceptional low-noise performance, especially given its award-winning NF-A9x14 fan. This fan operates quietly under load and remains whisper-quiet at idle, making it an excellent choice for users who prioritise a silent computing experience. For those sensitive to noise, the Noctua is likely the better option, providing performance without the disruptive sound.

Brand Reputation and Warranty

Brand reputation is a crucial factor in purchasing decisions, and both Thermalright and Noctua have established themselves as reliable manufacturers in the CPU cooling market. Thermalright has over 20 years of experience and a strong presence in both domestic and foreign markets. Noctua, on the other hand, has received more than 200 awards for its products, underscoring its commitment to quality. Additionally, Noctua backs its NH-L9i-17xx cooler with a six-year manufacturer's warranty, providing peace of mind for consumers regarding durability and performance. While both brands are reputable, Noctua's warranty and accolades lend it a stronger position in the eyes of consumers.

Aesthetic Appeal

When it comes to aesthetics, the Thermalright Peerless Assassin features colorful ARGB lighting effects, which can enhance the visual appeal of a build, especially for those who enjoy RGB setups. The dual fans also contribute to a more dynamic appearance. In contrast, the Noctua NH-L9i-17xx takes a more understated approach with a classic brown and beige colour scheme. While it may not have the flashy RGB lights, its sleek design is often appreciated in minimalist builds. Ultimately, the choice between these two will depend on personal preference regarding aesthetics; those drawn to vibrant lighting will favour the Thermalright, while fans of a more classic look may prefer Noctua.

Which should you buy?

The choice between the Thermalright Peerless Assassin 120 SE ARGB and the Noctua NH-L9i-17xx boils down to specific needs and preferences. If you are looking for an affordable, high-performance cooler with extensive compatibility, the Thermalright is the better option due to its lower price and superior TDP rating. However, if you prioritise a compact design, quiet operation, and a reputable brand with a solid warranty, the Noctua is an excellent choice. Ultimately, both products offer unique strengths, and your decision should align with your specific use case and aesthetic preferences.
