Dimension comparison
Price Comparison
When it comes to pricing, the Thermalright Assassin X 120R SE Plus CPU Cooler is significantly more affordable at C$25.59 compared to the Thermalright Frozen Notte 360 Black ARGB Water Cooling CPU Cooler, which is priced at C$65.37. This cost difference of C$39.78 may be a crucial factor for budget-conscious consumers who still want quality cooling solutions. While the Assassin X offers a solid performance at a lower price point, the Frozen Notte, with its advanced features, justifies its higher price for users looking for enhanced cooling capabilities.
Cooling Performance
The Thermalright Frozen Notte 360 is designed for superior cooling performance, featuring a water block with a full copper mirror plane base and three PWM fans that can reach speeds of 2000 RPM. This cooler boasts an impressive airflow of 72.37 CFM and is particularly effective in managing CPU temperatures under heavy loads. In contrast, the Thermalright Assassin X 120R SE Plus utilizes a more traditional air-cooling method with a dual-fan setup, offering a maximum airflow of 66.17 CFM at a fan speed of 1550 RPM. Although both coolers are effective, the Frozen Notte clearly leads in raw cooling performance due to its water-cooling design and higher airflow capabilities.
Noise Levels
The Thermalright Assassin X 120R SE Plus operates at a maximum noise level of 25.6 dB(A), making it an excellent choice for users seeking a quiet computing experience. Its dual PWM fans are designed to work efficiently while keeping noise to a minimum. On the other hand, the Frozen Notte 360's noise level sits slightly higher at a maximum of 27.7 dB(A). While both coolers are relatively quiet, the Assassin X edges out in terms of noise output, making it preferable for those who prioritise a silent operation in their builds.
Build Quality
In terms of build quality, both coolers are constructed with high-quality materials, but they differ in their design approaches. The Thermalright Frozen Notte 360 features a high-quality copper bottom and an aluminum alloy cover, ensuring durability and longevity, with an expected lifespan of up to 40,000 hours. The Assassin X, while also well-built, uses S-FDB bearings that contribute to its noise reduction and cooling efficiency but does not specify an equivalent lifespan. Both products reflect Thermalright’s commitment to quality, but the water-cooling design of the Frozen Notte may provide an edge in terms of long-term reliability and performance.
Installation and Compatibility
Installation processes vary between the two coolers. The Thermalright Frozen Notte 360 is designed for extensive compatibility with Intel CPUs, including LGA 1150 through 2066, and AMD systems from AM2 to AM5. Its dual platform full metal black buckle aids in easy installation. Conversely, the Assassin X supports a wide range of Intel sockets (1150 to 1700) and AMD sockets (AM4 and AM5), providing flexibility for various setups. While both coolers are compatible with a range of systems, the Frozen Notte’s comprehensive support for more Intel sockets gives it an advantage for users with diverse hardware configurations.
Aesthetic Features
Aesthetic appeal is another area where the Thermalright Frozen Notte 360 shines, thanks to its ARGB lighting. The integrated ARGB fans and water-cooling head can create vivid lighting effects that synchronise with other components via a 5V 3-pin connection. This feature allows users to customise the lighting to match their builds, providing a visually striking experience. In contrast, the Thermalright Assassin X does not mention any RGB features, which may make it less appealing to users who prioritise aesthetics in their setups. If visual flair is important, the Frozen Notte’s ARGB capabilities will be a significant draw.
Maintenance and Lifespan
Maintenance and lifespan considerations differ markedly between the two coolers. The Thermalright Frozen Notte 360 is built for longevity, with a pump head designed to last up to 40,000 hours and features that minimise evaporative loss. The cooling system aims to provide less resistance while maintaining high efficiency over time. In comparison, the Assassin X has a service life of up to 20,000 hours, which, while respectable, is notably shorter than its counterpart. Users seeking a cooling solution that will require less frequent maintenance and provide long-term reliability may find the Frozen Notte to be the superior choice.
Which should you buy?
Ultimately, the decision between the Thermalright Assassin X 120R SE Plus and the Thermalright Frozen Notte 360 Black ARGB Water Cooling CPU Cooler depends on your specific needs and preferences. If you are looking for a budget-friendly air cooler that delivers efficient cooling with minimal noise, the Assassin X is an excellent choice at C$25.59. However, if you desire superior cooling performance, aesthetic features with ARGB lighting, and are willing to invest more at C$65.37, the Frozen Notte 360 is likely the better option. Each cooler has its strengths, so consider your priorities regarding performance, aesthetics, and budget before making a final decision.
