Dimension comparison
Overview of the Thermalright Assassin X 120R and Thermalright PS120SE
The Thermalright Assassin X 120R is priced at $22.90, making it about 36% cheaper than the Thermalright PS120SE, which costs $35.90. This significant price difference might appeal to budget-conscious users looking for effective cooling solutions without compromising performance. Both products are designed for compatibility with various CPUs, including Intel and AMD, ensuring they cater to a wide audience of gamers and PC builders.
Performance and Cooling Efficiency
When it comes to cooling performance, the Thermalright PS120SE boasts a more robust cooling capacity with its seven heat pipes compared to the four found in the Assassin X 120R. This design allows the PS120SE to handle a thermal design power (TDP) of up to 280W, making it suitable for high-performance CPUs. In contrast, the Assassin X 120R, while effective, is designed for slightly lower performance scenarios, which may limit its appeal for users with high-end processors.
Fan Technology and Operation
The fan technology varies significantly between the two coolers. The Assassin X 120R features a 2000RPM performance-level PWM fan, designed to adjust its speed according to motherboard temperature, enhancing both cooling and noise control. On the other hand, the PS120SE uses dual 120mm TL-C12B V2 PWM fans with a maximum speed of 1500RPM, providing a balance of airflow and noise. While the Assassin X 120R may run slightly quieter due to its higher RPM specification, the dual fans of the PS120SE could offer better overall cooling efficiency.
Build Quality and Materials
Both coolers utilize high-quality materials, but they differ in construction and design features. The Assassin X 120R employs industrial-grade PBT+PC materials combined with UL class A safety insulation, ensuring durability. Conversely, the PS120SE features an anodized black frosted top and a finely carved pure copper base, maximizing heat dissipation area. The choice of materials in the PS120SE not only enhances its aesthetic appeal but also contributes to its performance capabilities, making it a solid choice for users prioritizing build quality.
Aesthetic Features
For those who value aesthetics in their build, the Assassin X 120R comes with a digital screen top cover and ARGB lighting that synchronizes with the motherboard, providing vibrant lighting effects while maintaining cooling performance. In comparison, while the PS120SE does not highlight ARGB features, its sleek design and dual-fan setup still offer a visually appealing cooling solution. Users looking for customizable lighting options may lean towards the Assassin X 120R.
Installation and Compatibility
Installation is straightforward for both coolers, but the PS120SE offers compatibility with a wider range of CPU sockets, including Intel LGA1700/1150/1151/1155/1156/1200 and AMD AM4/AM5. The Assassin X 120R also supports a variety of sockets but is slightly less versatile in this aspect. Compatibility can be a critical factor for builders, especially those with specific motherboard and CPU combinations.
Noise Levels
When considering noise levels, the Assassin X 120R is designed to minimize sound through its 2000RPM fan and silicone corner pads that reduce vibrations. While the PS120SE’s fans are rated at a noise level of less than 25.6dB(A) at maximum speed, the lower RPM and dual fan setup may generate more noise under heavy load. Users sensitive to noise might prefer the quieter operation of the Assassin X 120R, particularly in a home or office environment.
Which should you buy?
Ultimately, the decision between the Thermalright Assassin X 120R and the Thermalright PS120SE boils down to specific user needs. The Assassin X 120R is a great choice for budget-conscious buyers seeking effective cooling with appealing aesthetics and quieter operation at a lower price of $22.90. In contrast, the PS120SE, priced at $35.90, is a robust option for those needing superior performance, especially for high-end CPUs, thanks to its seven heat pipes and dual fan design. Each cooler has its strengths, making them suitable for different types of users and builds.
