Price Comparison
In terms of price, the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler is the more economical option at $22.90, making it about 17% cheaper than the Thermalright PS120SE ARGB CPU Air Cooler, which retails for $34.94. This price difference could be significant for budget-conscious consumers looking for an effective cooling solution without breaking the bank. Despite its lower price, the Assassin X 120R does not compromise on features, making it an attractive choice for those seeking value.
Design and Aesthetics
Both coolers boast modern designs tailored to enhance the appearance of any gaming rig. The Assassin X 120R features a digital screen top cover, contributing to a sleek aesthetic while providing practical functionality. In contrast, the PS120SE offers an impressive ARGB lighting system with up to 17 customizable modes, allowing for a more dynamic lighting experience. While the PS120SE is slightly taller at 154mm compared to the Assassin X 120R's height of 151mm, both are designed to fit within standard cases, ensuring compatibility with a wide range of builds.
Cooling Performance
When it comes to cooling capabilities, the PS120SE has a notable edge over the Assassin X 120R. The PS120SE is equipped with 7 heat pipes, compared to the 4 in the Assassin X 120R, which can enhance heat dissipation. Furthermore, the dual 120mm PWM fans of the PS120SE can reach a maximum speed of 1500 RPM, delivering a maximum airflow of 66.17 CFM, whereas the Assassin X 120R’s single fan can reach 2000 RPM. While the higher RPM of the Assassin X might suggest superior performance, the additional heat pipes and dual fans of the PS120SE provide a more robust overall cooling solution.
Noise Levels
Noise levels are a crucial factor for many users when selecting a CPU cooler. The Assassin X 120R's fan operates at a maximum speed of 2000 RPM but includes features such as silicone corner pads designed to minimize noise during operation. Conversely, the PS120SE's dual fans run at a maximum of 1500 RPM with a noise level capped at 25.6 dB(A), ensuring that it remains quiet even under load. For users prioritizing a quieter operation, the PS120SE may be the more appealing option, despite the Assassin X's noise-reduction features.
Installation and Compatibility
Both coolers offer broad compatibility with various CPU sockets, supporting Intel LGA1700, 1150, 1151, 1155, 1156, and 1200, as well as AMD AM4 and AM5. Installation processes for both models are streamlined, with the PS120SE providing the necessary mounting plates and fasteners for different platforms. The Assassin X 120R also has an accessible installation process, though the specific details are less emphasized in its description. For users concerned about compatibility with their existing hardware, both options provide the flexibility needed for a wide range of setups.
Build Quality
In terms of build quality, both products utilize industrial-grade materials. The Assassin X 120R is made from UL class A safety insulation grade PBT+PC materials, while the PS120SE features a combination of anodized black frosted top and finely carved pure copper base technology. Both coolers are designed for durability, but the PS120SE’s use of 7 heat pipes and a more complex construction may suggest a more robust quality overall. This could translate into longer-term reliability and performance, making the PS120SE a potentially more investment-worthy option.
User Experience
User experience can greatly influence the perceived value of a CPU cooler. The Assassin X 120R includes a digital screen that provides real-time data and is compatible with TRCC software, enhancing user interaction. On the other hand, the PS120SE’s ARGB lighting and dual fans can create a visually stunning effect in a build, which might appeal to gamers and PC enthusiasts looking to showcase their systems. While both coolers provide a satisfying user experience, those who prioritize aesthetics might lean toward the PS120SE, whereas users seeking functionality may prefer the Assassin X.
Which should you buy?
Ultimately, the choice between the Thermalright Assassin X 120R and the PS120SE hinges on personal priorities. If budget is a primary concern, the Assassin X 120R offers excellent performance at a lower price point of $22.90. However, for users willing to invest a bit more for enhanced cooling capabilities, quieter operation, and superior aesthetics, the Thermalright PS120SE at $34.94 presents a compelling case. Evaluating your specific needs—whether it be price, performance, or visual appeal—will guide you in making the best choice for your CPU cooling solution.
