Noctua NH-U12S vs Thermalright Assassin Spirit 120 EVO Dark CPU Cooler Air with 4×6mm HeatPipes

Overview of the Noctua NH-U12S and Thermalright Assassin Spirit 120 EVO Dark

The Noctua NH-U12S is a premium CPU cooler priced at C$79.95, while the Thermalright Assassin Spirit 120 EVO Dark offers a more budget-friendly option at C$24.90. This price difference of C$55.05 raises the question of what additional value the Noctua cooler provides compared to its Thermalright counterpart. Both coolers are designed to enhance CPU performance through effective heat dissipation, catering to users with different needs and budgets.

Cooling Performance

The Noctua NH-U12S features a highly optimised NF-F12 120mm fan, designed for focused airflow, which contributes to its outstanding cooling performance. This model is noted for balancing cooling efficiency with noise levels, ensuring ultra-quiet operation. On the other hand, the Thermalright Assassin Spirit 120 EVO Dark uses a PWM fan with a rotation speed of up to 1850 RPM, aiming for effective heat dissipation as well. While the Noctua is celebrated for its performance in various cases without overhanging RAM or PCIe slots, the Thermalright's design with four heat pipes is engineered to maximise heat dissipation. The Noctua's reputation for quality and performance gives it an edge, especially in high-performance scenarios.

Design and Aesthetics

In terms of design, the Noctua NH-U12S is a classic 120mm slim-tower cooler that not only performs well but also fits seamlessly into a variety of cases without obstructing other components. Its understated yet professional look is enhanced by a high-quality finish. Conversely, the Thermalright Assassin Spirit 120 EVO Dark stands out with its anodic black brushed top cover, appealing to users looking for a cooler that also offers a modern aesthetic. The unique appearance of the Thermalright may attract those who prioritise visual appeal alongside functionality.

Compatibility

The Noctua NH-U12S is compatible with a wide range of sockets including Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4. This extensive compatibility makes it a versatile choice for users who may upgrade their systems in the future. The Thermalright Assassin Spirit 120 EVO Dark also boasts a broad compatibility range, supporting Intel LGA1150/1151/1155/1156/1200/1700 and AMD AM4/AM5 sockets. While both coolers cater to a variety of setups, the Noctua's legacy and established performance across many platforms lend it a reliability that enthusiasts often prefer.

Installation Process

The installation process for the Noctua NH-U12S is simplified thanks to its SecuFirm2 mounting system, which facilitates easy setup across various motherboard types. Included thermal paste further streamlines the installation, specifically tailored for optimal thermal transfer. The Thermalright Assassin Spirit 120 EVO Dark also offers a straightforward installation experience, providing mounting plates and fasteners for different CPU socket types. However, it does require the use of the original backplate from the motherboard for AMD AM4/AM5 installations. Both coolers are designed for user-friendly installation but may differ in ease based on individual user experiences.

Noise Levels

One of the standout features of the Noctua NH-U12S is its low-noise operation, thanks to the incorporated Low-Noise Adaptor and PWM support, which automatically adjusts fan speeds. Users can expect a whisper-quiet performance, even under load. In contrast, the Thermalright Assassin Spirit 120 EVO Dark, while efficient, does not emphasise low-noise operation in its specifications. Therefore, users who prioritise a quieter computing environment may lean towards the Noctua for its proven silent operation, especially in high-performance tasks.

Price-to-Performance Ratio

The Thermalright Assassin Spirit 120 EVO Dark presents an exceptional price-to-performance ratio at C$24.90, making it an attractive option for budget-conscious consumers. It offers decent cooling capabilities for casual users and those with less demanding setups. However, for an additional investment of C$55.05, the Noctua NH-U12S provides superior performance, quieter operation, and reliability, which can be particularly beneficial for gamers or content creators who push their CPUs to the limit. The choice ultimately comes down to the specific needs and budget of the user.

Which should you buy?

Choosing between the Noctua NH-U12S and Thermalright Assassin Spirit 120 EVO Dark largely depends on your budget and cooling needs. If you seek a high-performance cooler with a reputation for quality, quiet operation, and extensive compatibility, the Noctua NH-U12S is worth the investment at C$79.95. However, if you are looking for an affordable option that still delivers adequate cooling for everyday tasks, the Thermalright Assassin Spirit 120 EVO Dark at C$24.90 is a solid choice. Ultimately, both coolers serve their purpose well, but they cater to different segments of the market.
