Overview of the Products

In this article, we will compare the Thermalright Peerless Assassin 120 SE CPU Air Cooler with the NZXT F120 RGB Core 120mm PWM Single Fan. The Thermalright cooler is priced at £26.90, while the NZXT fan is considerably more affordable at £11.99. This price difference reflects their intended uses, with the Thermalright product serving as a complete air cooling solution, while the NZXT fan functions as a supplementary cooling component.

Design and Build Quality

The Thermalright Peerless Assassin 120 SE features a robust design with dimensions of 125mm x 135mm x 155mm, making it a substantial presence in any build. It utilises a double tower cooling system that enhances its cooling efficiency. In contrast, the NZXT F120 RGB is designed as a single fan with a 120mm diameter, focusing more on aesthetics and airflow optimisation through its semi-translucent blades that diffuse its RGB lighting. While the Thermalright cooler is built for performance with a focus on heat dissipation, the NZXT fan prioritises visual appeal alongside functionality.

Cooling Performance

Cooling performance is one of the most critical aspects of any cooling solution. The Thermalright Peerless Assassin 120 SE boasts a maximum airflow of 66.17CFM and operates at a noise level of no more than 25.6dB(A), which is commendably quiet for its performance class. The fan speed can reach up to 1550rpm. On the other hand, the NZXT F120 RGB fan is designed to provide high airflow and static pressure but does not specify its maximum airflow or noise levels. It employs PWM control to adjust speeds for optimal cooling, ensuring that noise levels are kept low when full power isn't necessary.

Compatibility

When it comes to compatibility, the Thermalright cooler is designed to support a wide range of CPU sockets, including Intel's LGA1150 through LGA1700 and AMD's AM4 and AM5. This versatility allows it to be used with various setups, catering to a broader audience. The NZXT F120 RGB fan does not specify any compatibility limitations, making it suitable for standard 120mm fan mounts, but it is primarily designed as an additional cooling option rather than a standalone solution.

Installation Process

The installation of the Thermalright Peerless Assassin 120 SE is straightforward, thanks to its included mounting hardware for both Intel and AMD platforms. Its design accommodates the necessary space for memory clearance, which can ease the installation process in tight cases. In contrast, the NZXT F120 RGB fan is designed for easy installation with a standard mounting system, allowing users to replace or add fans with minimal effort. While both products are user-friendly, the Thermalright cooler may require more time and effort due to its larger size and dual-fan configuration.

Noise Levels

Noise levels are a significant consideration for many users, especially in quiet environments. The Thermalright Peerless Assassin 120 SE operates at a maximum of 25.6dB(A), which is quite low for an air cooler of its capabilities. This feature makes it an excellent choice for gamers and professionals who value a quieter workspace. The NZXT F120 RGB fan also prioritises quiet operation through its fluid dynamic bearing and anti-vibration features. However, it does not provide specific noise level statistics, leaving potential buyers to rely on general claims of silent operation.

Aesthetic Appeal

Aesthetically, the NZXT F120 RGB shines with its eight individually addressable RGB LEDs that create stunning light displays. This feature allows users to customise the lighting to match their builds, adding a personal touch. The Thermalright Peerless Assassin 120 SE, while functional, does not feature RGB lighting, focusing instead on performance. For users who value aesthetics alongside functionality, the NZXT fan offers more visual appeal, making it a popular choice for those building RGB-themed setups.

Price Comparison

There is a significant price difference between the two products, with the Thermalright Peerless Assassin 120 SE retailing at £26.90 and the NZXT F120 RGB priced at £11.99. This disparity reflects their differing roles; the Thermalright product is a comprehensive cooling solution suitable for high-performance CPUs, while the NZXT fan serves as an accessory to enhance airflow and aesthetics. Depending on your budget and cooling needs, this price point will influence which product is the better choice for you.

Which should you buy?

Ultimately, the choice between the Thermalright Peerless Assassin 120 SE CPU Air Cooler and the NZXT F120 RGB Core 120mm PWM Single Fan boils down to your specific needs. If you require a powerful CPU cooler that supports a variety of sockets and operates quietly, the Thermalright cooler is the superior option. Conversely, if you are looking for an affordable fan to enhance airflow and add RGB flair to your setup, the NZXT fan will serve you well. Consider your cooling requirements, budget, and aesthetic preferences when making your decision.
