Additionally, it includes an easy-to-access refill port, enhancing its longevity and usability.
Cooling Efficiency
In terms of cooling efficiency, the be quiet! Pure Loop 2 FX 240mm is likely to outperform the Thermalright Assassin X 120 SE. The liquid cooling design of the be quiet! unit allows for greater thermal management, especially under heavy loads. While the Thermalright cooler can handle a thermal design power (TDP) of 125 to 225W, the be quiet! cooler's design generally excels in maintaining lower temperatures during extended usage. This could be particularly beneficial for users who engage in overclocking or run resource-intensive applications.
Noise Levels
When it comes to noise levels, the Thermalright Assassin X 120 SE is rated at a maximum noise level of 25.6 dB(A), making it a quiet option for air cooling. The be quiet! Pure Loop 2 FX is designed specifically for minimal noise with its decoupled PWM pump, though specific dB ratings are not provided. In environments where silence is paramount, users might find the Thermalright cooler slightly more appealing due to its stated noise level, particularly for builds focused on silence rather than maximum cooling.
Installation and Compatibility
Both coolers offer solid compatibility with various Intel and AMD socket types, making installation straightforward. The Thermalright Assassin X 120 SE supports Intel sockets 115X/1200/1700/17XX and AMD AM4, while the be quiet! Pure Loop 2 FX supports a wider range of sockets including Intel 1700, 1200, and AMD AM5. The provided metal fasteners for the Thermalright cooler ensure a secure fit, while the easy-access refill port on the be quiet! cooler adds convenience for maintenance. The broader socket compatibility of the be quiet! unit might make it a more future-proof choice for those planning to upgrade their systems.
Aesthetics and Design
In terms of aesthetics, the be quiet! Pure Loop 2 FX clearly stands out with its ARGB illumination and sleek all-black design, which can enhance the visual appeal of any build. The Thermalright Assassin X 120 SE, while functional, does not offer the same level of visual flair, focusing instead on performance. Users who prioritise a visually striking build may favour the be quiet! cooler for its modern and stylish appearance, while those more concerned with raw performance might opt for the simpler design of the Thermalright unit.
Price Consideration
Price is a significant factor when comparing these two coolers. The Thermalright Assassin X 120 SE is priced at C$24.29, making it an affordable choice for budget-conscious builders. In contrast, the be quiet! Pure Loop 2 FX comes in at C$118.12, which represents a substantial investment in cooling technology. The price difference reflects the distinct cooling technologies employed; however, users must weigh whether the additional performance and features of the be quiet! cooler justify the higher cost.
