Brand Overview

Both the Thermalright PS120SE and the Thermalright Assassin X 120 SE belong to the reputable Taiwanese brand Thermalright, which boasts over 20 years of experience in the computer cooling market. While both models carry the Thermalright name and heritage, their design philosophies and target audiences differ significantly.

The PS120SE, priced at C$44.90, is positioned as a high-performance cooler with features that cater to more demanding users. In contrast, the Assassin X 120 SE is a more budget-friendly option at C$25.59, appealing to those looking for effective cooling without breaking the bank. This price discrepancy indicates differing levels of performance and features aimed at distinct consumer needs.

Cooling Performance

When it comes to cooling performance, both models utilize advanced AGHP (Advanced Gravity Heat Pipe) technology, but their specifications reflect their intended use cases. The PS120SE has a thermal design power (TDP) rating between 105W and 280W, which allows it to handle high-performance CPUs effectively. This broad capacity makes it suitable for overclocking and demanding gaming setups.

In comparison, the Assassin X 120 SE has a TDP rating ranging from 125W to 225W. While still capable of managing moderate performance CPUs, it may not be as effective for high-end builds or intense overclocking scenarios. The difference in TDP ratings suggests that while both coolers are competent, the PS120SE is better suited for users who push their systems to the limit.

Design and Build Quality

The design and build quality of these coolers reflect their performance targets. The PS120SE features a substantial height of 154mm, making it compatible with a wide range of chassis models. Its construction includes an aluminum heat sink and a finely carved pure copper base, enhancing its heat dissipation capabilities. Weighing in at 0.9kg, it represents a solid build quality that aligns with its higher price point.

On the other hand, the Assassin X 120 SE is slightly shorter at 148mm and lighter at 0.645kg. This makes it more suitable for medium-sized cases. While it also uses aluminum for its heat sink, the overall construction may not feel as robust as the PS120SE. The differences in weight and dimensions indicate that the PS120SE is designed for those who prioritize performance and durability, while the Assassin X focuses on practicality and ease of installation.

Fan Performance

Fan performance is crucial for effective cooling, and both coolers come equipped with PWM fans that deliver efficient airflow with low noise levels. The PS120SE uses the TL-C12B V2 fan, which spins at a maximum of 1500 RPM, producing an airflow of 66.17 CFM while maintaining a noise level of ≤25.6 dB(A). This combination of airflow and noise level is ideal for users seeking a quiet yet effective cooling solution.

In comparison, the Assassin X 120 SE features the TL-C12C fan, which operates at a slightly higher maximum RPM of 1550. It also provides an airflow of 66.17 CFM with the same noise level of ≤25.6 dB(A). Although the RPM is marginally higher, the airflow performance remains consistent across both models. This suggests that both fans are designed to strike a balance between cooling efficiency and quiet operation, catering to users who value a peaceful computing environment.

Compatibility

Compatibility with various CPU sockets is an important consideration for buyers. The PS120SE supports a wide range of Intel sockets, including LGA1700 and LGA115X, as well as AMD's AM4 and AM5. This broad compatibility ensures that users can integrate it into a variety of systems without concern.

The Assassin X 120 SE also offers good compatibility, supporting Intel sockets 115X and 1200, as well as AMD's AM4. However, it lacks support for some of the newer Intel sockets that the PS120SE accommodates. This limitation may influence buyers who are looking to build or upgrade to the latest systems. In terms of versatility, the PS120SE takes the lead, making it the better choice for users with diverse or future-proofing needs.

Installation Process

The installation process can significantly affect user experience, and both models come with their own mounting solutions. The PS120SE includes various mounting plates and fasteners that cater to different CPU socket platforms, ensuring a straightforward installation process. Its design appears to prioritize user convenience and compatibility with a variety of setups.

Similarly, the Assassin X 120 SE is equipped with metal fasteners for both Intel and AMD platforms, which facilitate a smooth installation. Although both coolers aim for ease of installation, the PS120SE's comprehensive support for various sockets and thoughtful design may provide a slight edge in user-friendliness.

Price Consideration

Price is a critical factor for many buyers, and there is a noticeable difference between the two coolers. The Thermalright PS120SE is priced at C$44.90, reflecting its advanced features and higher performance capabilities. For users seeking top-tier cooling solutions, this price may be justified by the benefits it offers.

Conversely, the Thermalright Assassin X 120 SE is available for C$25.59, making it an attractive option for budget-conscious consumers. While it may not match the PS120SE in terms of raw performance, it still provides solid cooling capabilities at a much lower price point. Ultimately, the decision may come down to the buyer's budget and performance needs.

Which should you buy?

Choosing between the Thermalright PS120SE and the Thermalright Assassin X 120 SE largely depends on your specific cooling needs and budget. If you are an enthusiast looking for maximum performance, especially for high-end CPUs, the PS120SE is the clear winner with its superior TDP rating, robust build quality, and broader compatibility. On the other hand, if you are a casual user or on a tighter budget, the Assassin X 120 SE offers great value and sufficient cooling for moderate performance systems. Ultimately, both coolers reflect Thermalright's quality, but your choice should align with your performance expectations and financial considerations.
