Overview of the Products

When comparing the Thermalright Assassin X120 SE ARGB CPU Air Cooler and the ARCTIC P14 Pro A-RGB fan, it’s essential to note their distinct purposes within the cooling category. The Thermalright Assassin X120 SE is a CPU cooler designed to manage the heat generated by processors, while the ARCTIC P14 Pro functions primarily as a case fan, providing airflow throughout the computer case. The Thermalright product is priced at £16.29, whereas the ARCTIC fan is more affordable at £12.49.

Design and Build Quality

The Thermalright Assassin X120 SE features a robust design with dimensions of 120mm in length, 71mm in width, and 148mm in height. Weighing 0.63kg, it employs an aluminium heat sink and includes metal fasteners compatible with various Intel and AMD sockets. This attention to build quality and material ensures durability and effective heat dissipation. In contrast, the ARCTIC P14 Pro is crafted with a focus on high static pressure and efficient performance. Its new fan blade design optimises airflow, making it suitable for dense radiators and mesh structures. While both products are well-engineered, the Thermalright’s design is more specialised for CPU cooling, whereas the ARCTIC fan excels in general airflow.

Cooling Performance

Performance-wise, the Thermalright Assassin X120 SE boasts a maximum airflow of 66.17 CFM (cubic feet per minute) and operates at a noise level of ≤25.6 dB(A), ensuring a quiet environment while effectively cooling the CPU. The ARCTIC P14 Pro, on the other hand, can reach speeds up to 3000 RPM, allowing it to adapt its cooling based on system demands. This fan can stop completely at less than 5% PWM, which can be beneficial for noise-sensitive environments. While both products deliver significant cooling capabilities, the ARCTIC fan provides greater flexibility with its adjustable speed range, making it versatile for various cooling scenarios.

Noise Levels and Operation

Noise levels are a critical consideration for users prioritising a quiet computing experience. The Thermalright Assassin X120 SE maintains a low noise level of ≤25.6 dB(A), ensuring minimal disruption during operation. The ARCTIC P14 Pro also features a self-lubricating fluid dynamic bearing that significantly reduces operational noise, making it ideal for quiet performance. While both fans are designed to operate quietly, the Thermalright cooler provides a specific noise rating, allowing for clearer expectations regarding its sound profile during use.

Compatibility and Installation

The Thermalright Assassin X120 SE offers extensive compatibility, supporting various Intel sockets, including LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, along with AMD AM4 and AM5. This versatility is crucial for users with different CPU platforms. The cooler also comes with the necessary mounting hardware for straightforward installation. The ARCTIC P14 Pro, while primarily a fan, is compatible with standard fan mounts and can be easily integrated into most cases. However, it does not focus on CPU-specific installations, making the Thermalright a more comprehensive solution for CPU cooling needs.

Aesthetic Appeal

Aesthetically, the Thermalright Assassin X120 SE ARGB cooler features colourful and gorgeous ARGB light effects that can enhance the visual appeal of a gaming rig or high-performance PC. The ARCTIC P14 Pro also offers A-RGB capabilities, which can be synchronised with other RGB components, providing a cohesive lighting experience. Both products cater to users who appreciate visual elements in their setup. However, the Thermalright cooler’s design is specifically tailored for showcasing its cooling prowess alongside aesthetic flair.

Price and Value

In terms of pricing, the Thermalright Assassin X120 SE is priced at £16.29, while the ARCTIC P14 Pro is considerably more affordable at £12.49. The price difference reflects their functionalities, with the Thermalright offering a complete CPU cooling solution, whereas the ARCTIC serves as a powerful case fan. For users looking for a dedicated CPU cooler, the investment in the Thermalright product may be justified, while those needing additional airflow for their system might find the ARCTIC fan to be a more cost-effective choice.

Which should you buy?

Deciding between the Thermalright Assassin X120 SE ARGB CPU Air Cooler and the ARCTIC P14 Pro A-RGB fan ultimately hinges on your cooling needs. If you require a dedicated CPU cooler with excellent compatibility and low noise levels, the Thermalright Assassin X120 SE is the superior choice. However, if you’re looking for a versatile case fan that offers high static pressure and adjustable speeds, the ARCTIC P14 Pro is an excellent option. Each product excels in its respective category, making your choice dependent on whether you prioritise CPU cooling or overall airflow in your system.
