Dimension comparison
Price Comparison
When considering price, the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is significantly more affordable at C$32.90 compared to the be Quiet! Pure Loop 2 FX 240mm, which retails for C$118.12. This substantial price difference of C$85.22 may influence budget-conscious consumers, particularly those who are looking for a cost-effective cooling solution without compromising too much on performance. Given that both products target gamers and PC enthusiasts, the Thermalright model presents a compelling value proposition for entry-level systems or users looking to save.
Design and Aesthetics
In terms of design, the Thermalright Assassin X 120R features a sleek and symmetrical all-aluminum fin structure that enhances its aesthetics while also promoting effective heat dissipation. On the other hand, the be Quiet! Pure Loop 2 FX 240mm boasts an elegant all-black design combined with vibrant ARGB illumination, making it visually striking. The clean, modern look of the be Quiet! model may appeal more to those who prioritise aesthetics in their build, while the Thermalright cooler offers a more utilitarian approach. Both products integrate ARGB lighting, but the visual impact may differ based on individual preferences.
Performance Capabilities
Performance is a crucial factor in any CPU cooler. The Thermalright Assassin X 120R operates at a fan speed of 2000 RPM, delivering a wind pressure of 2.63 mm H2O and an air volume of 70.84 CFM. This makes it a capable cooler for maintaining optimal CPU temperatures during intense gaming sessions. In contrast, the be Quiet! Pure Loop 2 FX 240mm features two high-speed 120mm PWM fans that ensure high air pressure and efficient cooling performance. Although specific RPM values for the fans aren't provided, the dual-fan configuration generally suggests enhanced cooling potential, making it advantageous for overclocking scenarios.
Noise Levels
Noise output is an important consideration for many users. The Thermalright Assassin X 120R has a rated operating noise level of ≤29.8 dB(A), which is relatively quiet, making it suitable for users who prefer a silent computing environment. Conversely, the be Quiet! Pure Loop 2 FX 240mm is designed with a doubly decoupled PWM pump that minimises vibration and operational noise, although specific dB ratings are not mentioned. This design philosophy indicates that the be Quiet! cooler is engineered for quiet operation, appealing to users who are sensitive to noise levels.
Compatibility
When it comes to compatibility, both coolers cater to a wide range of CPU sockets. The Thermalright Assassin X 120R supports Intel's LGA 1851/1700/1150/1151/1155/1156/1200 and AMD's AM4/AM5 sockets, making it versatile for various builds. Meanwhile, the be Quiet! Pure Loop 2 FX 240mm also supports Intel's 1700/1200/2066/1150/1151/1155/2011(-3) and AMD's AM5/AM4 sockets, ensuring that it can accommodate current-generation processors. This compatibility allows users of both products to seamlessly integrate them into their systems, regardless of platform preference.
Installation Process
The installation process can significantly impact user experience. The Thermalright Assassin X 120R comes with installation accessories and offers a manual or installation video for guidance, making it user-friendly for first-time builders. In contrast, the be Quiet! Pure Loop 2 FX 240mm features an easy-to-access refill port and includes a coolant bottle, which may appeal to those who appreciate the flexibility of maintaining their cooling system over time. While both coolers provide installation support, the unique features of the be Quiet! model may give it an edge for users looking for long-term maintenance options.
Cooling Efficiency
Cooling efficiency is paramount for high-performance systems. The Thermalright Assassin X 120R, with its 151mm height and effective 70.84 CFM airflow, is designed to efficiently dissipate heat while maintaining a compact profile. The be Quiet! Pure Loop 2 FX 240mm, with its dual-fan setup, inherently has the potential for superior cooling performance, especially when cooling high-end CPUs during heavy workloads. While both coolers are effective, the be Quiet! model’s larger radiator size generally allows for better thermal management, particularly beneficial for overclockers or users running demanding applications.
Which should you buy?
Ultimately, the decision between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the be Quiet! Pure Loop 2 FX 240mm hinges on your specific needs and budget. If you are looking for an affordable, efficient cooling solution with a compact design, the Thermalright cooler is an excellent choice at C$32.90. However, if you prioritise aesthetics, quieter operation, and enhanced cooling performance, particularly for high-end builds, the be Quiet! model at C$118.12 may be worth the investment. Consider your system requirements, aesthetic preferences, and budget to make the best choice for your setup.
