Brand Overview

Both the Thermalright PS120SE CPU Air Cooler and the Thermalright Assassin X 120R SE Plus CPU Cooler share the same brand, Thermalright, which has over 20 years of experience in the industry. Thermalright is well-regarded in both domestic and international markets, known for its focus on developing high-quality computer accessories. The PS120SE, priced at C$44.90, positions itself as a premium offering, while the Assassin X 120R SE Plus, at C$25.59, is a more budget-friendly option without sacrificing brand integrity.

Cooling Performance

The Thermalright PS120SE boasts a total of seven 6mm heat pipes designed with AGHP technology, allowing it to handle a thermal design power (TDP) range of 105W to 280W. This makes it suitable for high-performance CPUs. On the other hand, the Assassin X 120R SE Plus employs four 6mm heat pipes, also utilising AGHP technology, which assists in managing the inverse gravity effect during operation. Despite the fewer heat pipes, it maintains an impressive cooling capacity, making it a solid choice for mid-range systems.

Fan Design and Efficiency

Cooling efficiency is crucial in CPU coolers, and both models feature PWM fans for optimal performance. The PS120SE includes a TL-C12B V2 fan that operates at a maximum speed of 1500 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). In contrast, the Assassin X 120R SE Plus is equipped with two PWM fans, the TL-C12C and TL-C12RB V2, with speeds of 1550 RPM and 1500 RPM, respectively. The combined airflow from these fans is slightly lower at 66.17 CFM and 58 CFM, yet both models offer quiet operations within the same noise level threshold.

Build Quality and Materials

When it comes to construction, the PS120SE showcases a combination of anodized black frosted top and a finely carved pure copper base, ensuring high-quality heat dissipation. The use of industrial-grade PBT + PC materials adds to its overall durability, which is crucial for long-term use. The Assassin X 120R SE Plus, while also made from similar durable materials, focuses on effective fan performance with quality S-FDB bearings to minimise noise and prevent blade shaking. Both products demonstrate high build quality, but the PS120SE may offer a slight edge in terms of premium materials.

Size and Compatibility

Size can be a determining factor when selecting a CPU cooler. The PS120SE measures 125mm x 135mm x 154mm and is compatible with a wide array of Intel and AMD sockets, including more recent models like LGA1700 and AM5. The Assassin X 120R SE Plus is slightly more compact and also supports a range of socket types, including LGA1700 and AM5. The PS120SE's height of 154mm makes it compatible with various chassis models, appealing to those with space constraints.

Price Point

The PS120SE is priced at C$44.90, which reflects its advanced features and higher cooling performance capabilities. In contrast, the Assassin X 120R SE Plus is available for C$25.59, making it an attractive option for budget-conscious consumers. While the PS120SE offers superior cooling potential, the price difference of C$19.31 may be significant for those who do not require top-tier cooling performance.

User Experience and Installation

Both CPU coolers offer straightforward installation processes with corresponding mounting plates and fasteners for various CPU socket platforms. The PS120SE, with its larger size, may require a bit more care during installation to ensure compatibility, but both products come with adequate support to facilitate a smooth setup. User experiences generally highlight that both coolers perform well in their respective price categories, but the PS120SE is noted for its excellent cooling efficiency in high-demand scenarios.

Which should you buy?

Ultimately, your choice between the Thermalright PS120SE CPU Air Cooler and the Thermalright Assassin X 120R SE Plus CPU Cooler will depend on your specific needs and budget. If you are looking for a high-performance cooler capable of handling demanding CPUs with superior cooling efficiency, the PS120SE is worth the investment at C$44.90. However, if you are more budget-conscious and require a solid cooling solution for mid-range systems, the Assassin X 120R SE Plus at C$25.59 provides excellent value without compromising quality.
