This price difference reflects their target markets; the PS120SE aims for higher performance enthusiasts, while the Assassin X 120R SE V2 caters to cost-conscious consumers.
Cooling Performance
The Thermalright PS120SE features a cooling capacity with a thermal design power (TDP) range of 105W to 280W, making it suitable for high-performance CPUs. In contrast, the Assassin X 120R SE V2 utilises 4x6mm heat pipes with a slightly lower AGHP 3rd generation technology, but still ensures effective cooling. Both coolers have a maximum airflow of 66.17 CFM and maintain a noise level of ≤25.6 dB(A), offering a blend of performance and low noise. However, the PS120SE’s higher TDP rating indicates it can handle more demanding CPU workloads.
Design and Build Quality
In terms of design, the PS120SE has a height of 154mm, while the Assassin X 120R SE V2 is slightly shorter at 148mm. This difference in height may affect compatibility with certain cases. Both use a combination of industrial-grade materials such as PBT and PC, ensuring durability. The PS120SE features a finely carved pure copper base and anodized black frosted top, which not only enhances its aesthetic appeal but also contributes to its cooling efficiency. The Assassin X 120R SE V2, while also robust, features a self-luminous fan that adds a visual element, appealing to gamers and aesthetic enthusiasts.
Fan Performance
The fans on both models are designed for efficiency. The PS120SE uses the TL-C12B V2 fan, which operates at a speed of 1500 RPM, while the Assassin X 120R SE V2 utilises the TL-C12C-L V2 fan, with a slightly higher speed of 1550 RPM. Both fans are 120mm in size and share similar airflow ratings of 66.17 CFM, ensuring effective cooling. However, the PS120SE's fan is designed with a focus on stability and longevity, promising up to 20,000 hours of operational life, which may be a deciding factor for those prioritising durability.
Compatibility
Both coolers support a wide range of CPU sockets, including Intel's LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, and LGA1700, as well as AMD's AM4 and AM5. This makes both products versatile choices for various builds. The PS120SE includes corresponding mounting plates for different CPU socket platforms, ensuring compatibility across most systems. The Assassin X 120R SE V2 also provides necessary mounting hardware, making both options easy to install for users upgrading or building new systems.
Noise Levels
When it comes to noise levels, both the Thermalright PS120SE and Assassin X 120R SE V2 operate at a maximum of ≤25.6 dB(A). This low noise emission is commendable, especially for users who prefer a quiet computing environment. The design of both coolers allows for efficient airflow without compromising on sound levels, making them suitable for both gaming and professional settings where noise can be a distraction.
Price Comparison
The price difference between the two coolers is significant, with the Thermalright PS120SE priced at C$44.90 and the Assassin X 120R SE V2 at a more affordable C$23.59. This makes the Assassin X 120R SE V2 an attractive option for budget-conscious consumers or those looking for solid cooling performance without breaking the bank. However, the PS120SE offers more advanced cooling capabilities, which may justify its higher price for users seeking top performance.
