Brand Overview

Both the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright PS120SE ARGB CPU Air Cooler come from the reputable brand Thermalright, which has over 20 years of experience in the computer accessories market. The Assassin X 120 SE ARGB is priced at C$24.29, while the PS120SE ARGB is significantly more expensive at C$63.68. The brand's focus on research and development is evident in both products, which are designed to cater to a wide range of cooling needs for gamers and PC enthusiasts alike.

Design and Build Quality

The Thermalright Assassin X 120 SE ARGB features a compact size of 125mm in length, 71mm in width, and a height of 148mm, making it suitable for medium-sized cases. It weighs 0.645kg and is constructed with high-quality aluminum. In contrast, the PS120SE ARGB is larger, measuring 125mm long, 135mm wide, and 154mm high, and it is made of anodized black frosted top and pure copper base technology. The PS120SE's design focuses on maximizing heat dissipation area, while the Assassin X ensures compatibility with various platforms without compromising on size.

Cooling Performance

When it comes to cooling performance, the Thermalright Assassin X 120 SE ARGB is equipped with a single PWM fan that operates at a speed of 1550 RPM and offers an airflow of 66.17 CFM. This cooler is rated for a thermal design power (TDP) of 125 to 225W, making it suitable for a wide range of CPUs. On the other hand, the PS120SE ARGB features dual PWM fans that run at 1500 RPM, also providing 66.17 CFM of airflow. The PS120SE’s dual-fan configuration may offer enhanced cooling efficiency, particularly in demanding conditions, while both coolers maintain a noise level of ≤25.6 dB(A).

Noise Levels

Noise levels are an essential consideration for many users, and both coolers perform admirably in this regard. The Thermalright Assassin X 120 SE ARGB maintains a maximum noise level of ≤25.6 dB(A) during operation, ensuring a quiet computing experience. Similarly, the Thermalright PS120SE ARGB also boasts the same noise level of ≤25.6 dB(A), thanks to its PWM fans. Users can expect a quiet performance from either cooler, making them both suitable for environments where noise is a concern.

Compatibility

Compatibility varies slightly between the two coolers. The Assassin X 120 SE ARGB supports Intel sockets 115X, 1200, 1700, and 17XX, along with AMD's AM4. The PS120SE ARGB, however, expands this compatibility to include Intel sockets LGA1700, 1851, 1150, 1151, 1155, 1156, and 1200, as well as AMD's AM4 and AM5 sockets. This broader support for various CPU sockets in the PS120SE makes it a more versatile choice for users looking to upgrade or build a new system.

Lighting Features

The lighting features of these coolers are quite different. The Thermalright Assassin X 120 SE ARGB does not specify any advanced lighting effects but focuses on performance and quiet operation. Conversely, the Thermalright PS120SE ARGB includes high-brightness LED atomizing ARGB fan blades that can showcase up to 17 different lighting modes. This allows for greater customization and synchronization with other RGB components in a build, making the PS120SE a more visually appealing option for those who value aesthetics.

Price Comparison

There is a significant price difference between the two coolers, which may influence purchasing decisions. The Thermalright Assassin X 120 SE ARGB is priced at a budget-friendly C$24.29, appealing to users looking for an effective cooling solution without breaking the bank. In contrast, the Thermalright PS120SE ARGB is priced at C$63.68, making it a premium option that offers additional features such as dual fans and advanced RGB lighting. This price difference reflects the additional features and enhanced cooling capabilities of the PS120SE.

Which should you buy?

Ultimately, the choice between the Thermalright Assassin X 120 SE ARGB and the Thermalright PS120SE ARGB depends on your specific needs and budget. If you're looking for a cost-effective cooling solution that performs well and maintains a quiet operation, the Assassin X 120 SE ARGB is a solid choice at C$24.29. However, if you require superior cooling performance, broader compatibility, and enhanced RGB lighting features, the PS120SE ARGB, though more expensive at C$63.68, may be worth the investment. Consider your priorities in terms of performance, compatibility, and aesthetics to make the best decision for your build.
