Noctua NH-L12S vs Thermalright Peerless Assassin 120 SE V2 CPU Cooler

Overview of the Noctua NH-L12S and Thermalright Peerless Assassin 120 SE V2

In the world of CPU coolers, the Noctua NH-L12S and the Thermalright Peerless Assassin 120 SE V2 stand out as two compelling options. With the Noctua priced at C$87.95 and the Thermalright at C$54.90, both coolers cater to different segments of the market, providing unique features tailored for specific user needs. The choice between them may hinge on cooling performance, size, and installation ease.

Design and Dimensions

The Noctua NH-L12S boasts a compact design, measuring only 70mm in height, making it ideal for small form factor builds like ITX and HTPC systems. In contrast, the Thermalright Peerless Assassin 120 SE V2 is larger, with dimensions of 125mm x 135mm x 155mm. This larger structure allows for potentially better cooling performance due to increased surface area. While the Noctua is designed for tight spaces, the Thermalright's design may appeal to those prioritizing cooling efficiency over compactness.

Cooling Performance

When it comes to cooling capabilities, the Thermalright Peerless Assassin 120 SE V2 uses six 6mm heat pipes that enhance thermal conductivity and support a thermal design power (TDP) of up to 265W. This is significantly higher than what the Noctua NH-L12S is recommended for, as it is optimized for CPUs with moderate heat loads. The Noctua features a highly optimised NF-A12x15 120mm fan with a focus on low-noise operation, making it an excellent choice for users who value silence alongside efficiency.

Noise Levels

Noise output is critical for users concerned about system acoustics. The Noctua NH-L12S excels in this department with its Low-Noise Adaptor, ensuring ultra-quiet operation during PWM fan control. While the Thermalright Peerless Assassin 120 SE V2 can produce noise levels of up to 29.5 dB(A), the Noctua is engineered for nearly silent performance, appealing to those who prefer a whisper-quiet computing environment. Therefore, if low noise is a priority, the Noctua may be the superior option.

Installation and Compatibility

In terms of installation ease, the Noctua NH-L12S includes the SecuFirm2 mounting system, which simplifies the installation process for both Intel and AMD platforms. It supports a wide range of sockets including Intel LGA1851, LGA1700, and AMD AM5 & AM4. The Thermalright Peerless Assassin 120 SE V2 also provides comprehensive compatibility with various Intel and AMD sockets, but its larger size may complicate installation in tighter cases. For users looking for a straightforward install, the Noctua's design may make it the more user-friendly option.

Thermal Paste and Accessories

Both coolers include high-quality thermal paste, but the Noctua NH-L12S comes with the renowned NT-H1 thermal paste, known for its excellent thermal conductivity. On the other hand, the Thermalright Peerless Assassin 120 SE V2 does not specify the thermal paste quality but includes metal fasteners for secure installation. The inclusion of superior thermal paste in the Noctua package may provide an additional edge in thermal performance, especially for users seeking optimal cooling efficiency.

Price Consideration

Price is often a deciding factor for consumers, and here the Thermalright Peerless Assassin 120 SE V2 significantly undercuts the Noctua NH-L12S at C$54.90 compared to C$87.95. This makes the Thermalright a more budget-friendly choice, especially for gamers or overclockers who need high-performance cooling without breaking the bank. However, the higher price of the Noctua might be justified by its compact design and quieter operation, appealing to users with specific needs.

User Experience and Reviews

User feedback often highlights the efficiency and reliability of both coolers. The Noctua NH-L12S is frequently praised for its silent operation and effective cooling in compact cases, making it a favourite among HTPC builders. Conversely, the Thermalright Peerless Assassin 120 SE V2 receives accolades for its high cooling performance and value for money. Users looking for performance in larger cases without the need for a low-profile cooler may lean towards the Thermalright, while those focused on compact builds will likely favour the Noctua.

Which should you buy?

Ultimately, the choice between the Noctua NH-L12S and the Thermalright Peerless Assassin 120 SE V2 depends on your specific needs and build considerations. If you are working with a compact case and value low noise levels, the Noctua NH-L12S is a stellar choice. However, if you require more robust cooling performance and are operating within a larger case, the Thermalright Peerless Assassin 120 SE V2 offers excellent value at a lower price. Evaluate your requirements, and you will find the cooler that best fits your system.
