Overview of Thermalright PS120SE and Thermalright Assassin X 120R
The Thermalright PS120SE CPU Air Cooler is priced at C$44.90, while the Thermalright Assassin X 120R Digital ARGB White CPU Cooler is more budget-friendly at C$28.39. This price difference reflects their design, features, and target users. The PS120SE is positioned as a premium cooler with advanced features, while the Assassin X 120R offers solid performance at a lower cost.
The Thermalright PS120SE features a heat pipe system with a TDP rating of 105W to 280W, making it suitable for high-performance CPUs. In contrast, the Assassin X 120R, while effective, has a focus on aesthetics with its digital screen and RGB lighting, appealing to gamers and users who enjoy customisation.
Design and Aesthetics
The design of a CPU cooler can greatly influence a user's choice, and both models showcase distinct aesthetics. The PS120SE sports a sleek and minimalistic black frosted top, providing a professional look that fits well in any build. It focuses on performance over flair, which may appeal to users prioritising functionality.
On the other hand, the Assassin X 120R includes a digital screen on its top cover that allows users to monitor CPU and GPU temperatures in real-time. This feature not only enhances its visual appeal with customizable RGB lighting but also provides practical benefits for users who want to keep tabs on their system’s performance. The combination of functionality and style in the Assassin X 120R makes it an attractive choice for gamers and PC enthusiasts.
Performance and Cooling Efficiency
When it comes to cooling performance, the PS120SE is engineered for high TDPs, rated between 105W and 280W. This makes it a robust option for overclocking and high-performance CPUs, utilising its 7x6mm heatpipe technology to ensure effective heat dissipation. The use of an industrial-grade PWM fan with a maximum airflow of 66.17 CFM at a noise level of 25.6 dB(A) further enhances its cooling capabilities.
In comparison, the Assassin X 120R also employs AGHP heat pipe technology, featuring a 4x6mm configuration that addresses the anti-gravity issue in different mounting orientations. Its 2000 RPM PWM fan provides a solid cooling performance but does not specify an airflow rate, which could be a concern for users seeking maximum efficiency. The focus on aesthetics may slightly compromise its cooling capability relative to the PS120SE, primarily aimed at users looking for both performance and visual appeal.
Compatibility
Both the PS120SE and Assassin X 120R offer broad compatibility with various CPU sockets, making them versatile choices for many builds. The PS120SE supports Intel sockets, including LGA1700, LGA1851, LGA1150, LGA1151, LGA1155, LGA1156, and LGA1200, as well as AMD’s AM4 and AM5. This extensive compatibility ensures that it can be integrated into a wide range of systems.
Similarly, the Assassin X 120R is designed to work with dual platforms, supporting Intel and AMD sockets, although specific socket models are not detailed. This broad compatibility is essential for users building or upgrading systems, allowing both coolers to cater to a large audience.
Noise Levels
Noise levels are an important consideration for many users when selecting a CPU cooler. The PS120SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a cooler designed for higher TDPs. This makes it suitable for users who prefer a quieter computing environment, particularly when performing tasks that require minimal noise.
In contrast, while the Assassin X 120R does not specify its noise level, it incorporates silicone corner pads around the fan to reduce noise generated by rotation. This feature suggests that it is engineered to be quieter, although without specific metrics, users may find it challenging to compare directly with the PS120SE. For those prioritising a silent operation, the PS120SE may have a slight edge in measurable performance.
User Monitoring Features
The Assassin X 120R stands out with its digital screen top cover that displays real-time information regarding CPU temperature, CPU usage, and graphics card temperature. This user-friendly feature not only enhances the cooler's functionality but also appeals to tech enthusiasts who enjoy monitoring their system's performance closely. The ability to visually track these metrics adds a layer of interactivity that the PS120SE lacks.
In contrast, the PS120SE does not offer any built-in monitoring features, focusing instead on providing reliable cooling. Users who want to keep an eye on their system’s metrics will find the Assassin X 120R to be a more appealing option, especially if they appreciate the integration of technology in their hardware.
Durability and Longevity
Durability is crucial for any computer component, and both coolers are built with quality materials. The PS120SE boasts a lifespan of up to 20,000 hours, thanks to the S-FDB bearings and the use of industrial-grade materials. This makes it a reliable long-term investment for users looking for a cooler that can withstand extended usage.
The Assassin X 120R also employs high-quality materials with UL CLASSA safety insulation and features a high-speed fan designed to operate effectively. However, specific lifespan metrics are not provided, which may leave some users uncertain about its longevity compared to the PS120SE. For those prioritising durability, the PS120SE may offer more peace of mind.
Which should you buy?
Choosing between the Thermalright PS120SE and the Thermalright Assassin X 120R ultimately depends on your specific needs and preferences. If you prioritise high-performance cooling with extensive compatibility and durability, the PS120SE at C$44.90 is the superior choice. Its robust design and proven cooling capabilities make it ideal for high-end systems and overclocking.
Conversely, if you are looking for a more budget-friendly option with appealing aesthetics and user monitoring features, the Assassin X 120R at C$28.39 is a compelling alternative. Its digital screen and RGB lighting cater to users who appreciate visual appeal alongside functionality. Ultimately, both coolers have their strengths, making them suitable for different user profiles in the ever-evolving landscape of PC building.
