Thermalright Peerless Assassin 120 Digital ARGB Black CPU Cooler Air with 6X6mm vs Noctua NH-L9i-17xx

Price Comparison

When it comes to pricing, the Thermalright Peerless Assassin 120 Digital ARGB Black is priced at C$62.90, while the Noctua NH-L9i-17xx comes in slightly lower at C$59.95. This C$2.95 difference may seem minimal, but it can influence budget-conscious consumers. The Thermalright cooler offers additional features, such as dual fans and ARGB lighting, which might justify its higher price for some users. However, those looking for a more compact solution may find the Noctua's price more appealing, especially since it is tailored for small form factor cases.

Cooling Performance

Cooling performance is a critical aspect when selecting a CPU cooler. The Thermalright Peerless Assassin 120 boasts a fan speed of 1850 RPM and an airflow of 88.89 CFM, which suggests robust cooling capabilities. In comparison, the Noctua NH-L9i-17xx features a slim 92mm fan with automatic PWM speed control, though specific airflow figures are not provided. While the Thermalright's higher RPM and airflow numbers indicate superior cooling performance, the Noctua is designed for moderate heat loads, making it suitable for users with less demanding setups.

Size and Compatibility

In terms of size, the Thermalright Peerless Assassin stands at 162mm tall, making it compatible with mainstream ATX chassis. This height allows for extensive cooling without encroaching on memory slots. On the other hand, the Noctua NH-L9i-17xx is only 37mm tall, designed specifically for compact HTPC and Small Form Factor (SFF) cases. Its tailored footprint guarantees 100% RAM and PCIe compatibility on all ITX, Micro-ATX, and ATX motherboards. Thus, users needing a compact solution may lean towards the Noctua, while those with bigger cases could take advantage of the Thermalright's impressive cooling capabilities.

Design and Aesthetics

Aesthetics and design play a significant role in the selection process for many users. The Thermalright Peerless Assassin features a sleek, all-black design complemented by a digital display board on its magnetic top cover. This not only enhances its visual appeal but also adds a touch of modern technology, allowing users to monitor CPU temperatures easily. In contrast, the Noctua NH-L9i-17xx follows a more traditional design with its renowned NF-A9x14 fan. While it may not have the flashy aesthetics of the Thermalright, its proven design has earned it over 200 awards for performance and reliability, appealing to users who value function over form.

Noise Levels

Noise levels are a crucial factor in determining the comfort of a PC setup, especially for users seeking a quieter experience. The Thermalright Peerless Assassin operates at a noise level of ≤25.6 dB(A), which is relatively quiet for a high-performance cooler. The Noctua NH-L9i-17xx, paired with its Low-Noise Adaptor, is designed to provide full cooling performance under load while remaining whisper-quiet during idle conditions. While both coolers aim for quiet operation, the Noctua’s adaptive speed control may give it an edge in maintaining lower noise levels during less demanding tasks.

Installation and Ease of Use

When it comes to installation, both coolers offer user-friendly features. The Thermalright Peerless Assassin includes a 4PIN PWM power supply interface, allowing for straightforward connections. However, it does not detail the installation process. In contrast, the Noctua NH-L9i-17xx comes with the SecuFirm2 mounting system, which is known for its ease of installation, especially on Intel LGA1700 and LGA1851 CPUs. This detail could make the Noctua a more attractive option for users who may not be as experienced with CPU cooler installations.

Warranty and Reliability

Warranty and reliability are essential considerations when investing in computer hardware. The Thermalright Peerless Assassin does not specify a warranty period, which may raise concerns about long-term reliability. On the other hand, the Noctua NH-L9i-17xx is backed by a 6-year manufacturer’s warranty. This commitment to quality provides peace of mind for users who want assurance that their investment is protected. The Noctua's established reputation and extensive warranty further solidify its standing as a reliable choice in the CPU cooler market.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black and the Noctua NH-L9i-17xx ultimately depends on your specific needs and preferences. If you require superior cooling performance and have the space for a larger cooler, the Thermalright may be the better option, despite its higher price. Conversely, if you're looking for a compact cooler that excels in quieter operation and offers a long warranty, the Noctua is a solid choice. Both coolers have their strengths, making them suitable for different user scenarios in the ever-evolving landscape of CPU cooling solutions.
