Brand Overview

Both products come from Thermalright, a brand with over 20 years of experience in developing computer accessories. However, they cater to slightly different needs within the CPU cooling market. The Thermalright Assassin X 120R SE V2 CPU Air Cooler is designed for efficient cooling with a focus on low noise levels, while the Thermalright PS120SE ARGB CPU Air Cooler adds aesthetic appeal with ARGB lighting, appealing to users who value both performance and design.

Price Comparison

In terms of pricing, the Thermalright Assassin X 120R SE V2 is significantly more affordable at C$23.59, compared to the Thermalright PS120SE ARGB, which is priced at C$63.68. This substantial difference of C$40.09 may influence budget-conscious consumers or those seeking basic cooling solutions without the need for additional features like RGB lighting.

Cooling Performance

The cooling performance of both coolers is impressive, with airflow ratings at 66.17 CFM. The Assassin X 120R SE V2 utilises a single PWM fan running at a maximum speed of 1550 RPM, while the PS120SE ARGB features dual PWM fans with a maximum speed of 1500 RPM. The dual fans of the PS120SE ARGB may offer a slight advantage in cooling efficiency due to increased air movement, although both models maintain a comparable noise level of ≤25.6 dB(A).

Design and Aesthetics

In terms of design, the Thermalright PS120SE ARGB stands out with its ARGB lighting effects, featuring up to 17 modes that can be synchronized with a motherboard. This cooler not only focuses on performance but also aims to enhance the visual appeal of a build. The Assassin X 120R SE V2, while functional and stylish, does not offer the same level of aesthetic customization, making it less appealing for users who prioritise visual elements in their setups.

Build Quality

Both coolers showcase solid build quality, employing durable materials. The Assassin X 120R SE V2 is constructed using industrial-grade PBT + PC material, while the PS120SE ARGB features an anodized black frosted top and a finely carved pure copper base. Both models have a service life of up to 20,000 hours thanks to S-FDB bearings. However, the PS120SE ARGB, with its added complexity of ARGB components, may require more careful installation and handling.

Compatibility

When it comes to compatibility, both coolers support a range of CPU sockets including Intel LGA1150 to LGA1700 and AMD AM4/AM5. However, the PS120SE ARGB has a slightly greater height of 154mm compared to the Assassin X 120R SE V2's 148mm. This may impact installation in compact cases, especially for users with limited vertical space. Both products come with corresponding mounting plates, ensuring a straightforward installation process.

Noise Levels

Both coolers maintain a noise level of ≤25.6 dB(A), which is relatively quiet for CPU cooling solutions. This makes both the Thermalright Assassin X 120R SE V2 and the PS120SE ARGB suitable for users who prefer a quieter computing experience. The low noise levels are achieved through efficient fan designs, ensuring that neither model sacrifices performance for silence.

Which should you buy?

Choosing between the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright PS120SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you are looking for a budget-friendly option that delivers solid cooling performance without any frills, the Assassin X 120R SE V2, priced at C$23.59, is an excellent choice. On the other hand, if you desire enhanced aesthetics with ARGB lighting and are willing to invest more for it, the PS120SE ARGB at C$63.68 offers superior visual appeal alongside commendable cooling efficiency. Both coolers are well-built and compatible with various CPU sockets, ensuring that either option will serve you well in your computing setup.
