Dimension comparison
Price Comparison
The Thermalright Assassin X 120R Digital ARGB White CPU Cooler is priced at C$28.39, while the Thermalright Peerless Assassin 120 SE Black CPU Cooler is considerably higher at C$46.79. This represents a significant price difference of C$18.40, making the Assassin X a more budget-friendly option for those looking for effective cooling solutions. However, the higher price of the Peerless Assassin may reflect its advanced features and dual tower design, which could justify the investment for users seeking enhanced performance.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 120 SE boasts dual PWM fans that can reach a speed of 1550 RPM, providing an air volume of 66.17 CFM. This dual fan setup enhances airflow and improves heat dissipation, making it a robust choice for users with demanding cooling needs. On the other hand, the Thermalright Assassin X features a single fan that operates at a higher speed of 2000 RPM, but with a lower overall airflow due to its single-fan design. While both coolers are designed to dissipate heat effectively, the Peerless Assassin's dual fan configuration may yield superior performance under heavy loads.
Design and Aesthetics
The design of the Thermalright Assassin X 120R is characterized by its striking digital ARGB lighting and a sleek white finish. This cooler not only serves a functional purpose but also adds a visual appeal to any build. The digital screen on top allows users to monitor CPU temperature and usage in real time. Conversely, the Thermalright Peerless Assassin 120 SE features a blackened nano coating and a more industrial look, which may appeal to users who prefer a more understated aesthetic. While both coolers have unique design elements, the choice ultimately depends on personal taste and the overall theme of the user's PC build.
Installation and Compatibility
The Thermalright Peerless Assassin 120 SE is designed with user-friendliness in mind, offering compatibility with a wide range of Intel and AMD CPU sockets, including LGA1150 to LGA1700 for Intel and AM4 to AM5 for AMD. Its dual tower and dual fan design also facilitate easier installation and better clearance for RAM and chassis compatibility. In contrast, the Thermalright Assassin X also supports dual platforms but does not specify as many socket options. Both coolers come with appropriate mounting hardware, but the Peerless Assassin's thoughtful design may provide a more straightforward installation experience.
Noise Levels
When it comes to noise levels, the Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet and should not cause significant disturbances during operation. The PWM fans are designed to adjust their speed based on temperature, ensuring optimal performance without unnecessary noise. The Thermalright Assassin X, while not providing a specific noise level, also features a fan designed to minimize noise through silicone corner pads that reduce vibration. While both coolers aim for quiet operation, the Peerless Assassin's explicitly stated noise level gives it an edge for users sensitive to sound.
Material and Build Quality
Build quality is an important consideration when selecting a CPU cooler. The Thermalright Peerless Assassin 120 SE is constructed with a combination of aluminum and a fully electroplated heat pipe, contributing to its durability and effective heat dissipation. Its fine micro-carved copper bottom increases the effective heat dissipation area, making it a solid choice for long-term use. Meanwhile, the Thermalright Assassin X incorporates UL CLASSA safety insulation grade materials and features S-FDB bearings for enhanced stability. Both coolers exhibit strong build quality, but the Peerless Assassin's materials and construction techniques may provide superior long-term performance.
User Experience and Monitoring
User experience is enhanced with the Thermalright Assassin X, which features a digital screen that allows for real-time monitoring of CPU and GPU temperatures, as well as CPU usage. This functionality can be particularly useful for enthusiasts who want to keep an eye on their system's performance. The accompanying TRCC software further enriches the user experience by facilitating easy data tracking. In contrast, the Thermalright Peerless Assassin 120 SE focuses more on performance and efficiency, lacking such a monitoring feature. Users who value real-time data may lean towards the Assassin X for its user-friendly display.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB White CPU Cooler and the Thermalright Peerless Assassin 120 SE Black CPU Cooler ultimately depends on your specific needs and budget. If you are looking for an affordable option with a unique aesthetic and real-time monitoring features, the Assassin X is a great choice at C$28.39. However, if you prioritize superior cooling performance, a dual fan setup, and robust construction, the Peerless Assassin at C$46.79 may be worth the extra investment. Each cooler has its strengths, and understanding your priorities will lead you to the right decision.
