Overview of Thermalright Assassin X 120 SE ARGB CPU Air Cooler
The Thermalright Assassin X 120 SE ARGB CPU Air Cooler is an efficient air cooling solution priced at C$24.29. It features a compact design, measuring 125mm in length and 148mm in height, making it suitable for various mid-sized computer cases. With a weight of 0.645 kg, this cooler is designed for easy installation on Intel and AMD platforms, offering compatibility with a wide range of CPU sockets.
The cooler employs advanced technology, including four 6mm heat pipes that utilise AGHP techniques to improve heat dissipation. It supports a thermal design power (TDP) range of 125 to 225W, ensuring it can handle a broad spectrum of CPU performance requirements. The included PWM fan operates at a maximum speed of 1550 RPM, producing a maximum airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A), making it a quiet yet effective cooling option.
Overview of Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler
The Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler is a more advanced cooling solution, retailing for C$62.90. This cooler features a dual 120mm fan setup and a 240mm radiator, which significantly enhances its cooling capacity. With the ability to cool high-performance CPUs effectively, it is engineered to meet the demands of gamers and professionals alike.
The water block incorporates a full copper mirror plane base, ensuring efficient thermal transfer. It operates at a maximum pump speed of 5300 RPM, which contributes to its superior cooling performance. The dual PWM fans can reach speeds of 2000 RPM, generating a maximum airflow of 72.37 CFM while maintaining a noise level of 27.7 dB(A). The ARGB features of this cooler not only enhance aesthetics but also allow for synchronisation with the motherboard, creating a visually impressive setup.
Cooling Performance Comparison
When it comes to cooling performance, the Thermalright Frozen Notte 240 clearly outshines the Assassin X 120 SE. The Frozen Notte’s 240mm radiator and dual fans provide a greater surface area for heat dissipation compared to the 120mm air cooler. With a maximum airflow of 72.37 CFM, the Frozen Notte is capable of cooling even the most demanding CPUs, while the Assassin X 120 SE provides a respectable 66.17 CFM.
The water cooling solution's pump speed of 5300 RPM and advanced copper construction contribute to its ability to sustain lower temperatures, particularly under heavy loads. In contrast, the air cooler’s maximum fan speed of 1550 RPM, while efficient, does not match the cooling capacity of the Frozen Notte. Therefore, for users seeking optimal thermal management, the Frozen Notte is the superior choice.
Noise Levels and Operating Environment
In terms of noise levels, both coolers are designed to operate quietly, but the Thermalright Assassin X 120 SE has a slight advantage. Its maximum noise level reaches only 25.6 dB(A), making it one of the quieter options in air cooling. This is particularly beneficial for users who prioritise a silent operating environment, such as those working in offices or quiet home setups.
Conversely, the Frozen Notte operates at a maximum noise level of 27.7 dB(A). While still relatively quiet, it is slightly louder than the Assassin X 120 SE. However, considering its superior cooling performance, the slight increase in noise may be a worthwhile trade-off for users requiring enhanced cooling capabilities, especially during intense gaming or heavy computational tasks.
Installation and Compatibility
The Thermalright Assassin X 120 SE is designed for ease of installation, compatible with Intel sockets 115X/1200/1700/1700 and AMD AM4. This wide compatibility ensures that it can be installed on a variety of systems without complications. Additionally, its compact size makes it a suitable option for mid-sized cases, allowing for straightforward integration.
The Frozen Notte, with its dual-fan and larger radiator design, also supports a broad range of socket types, including Intel’s LGA 1150 through 2066 and AMD’s AM4/AM5. However, it is recommended that the chassis width be greater than 250mm for optimal installation. While the installation process may be slightly more complex due to its water cooling design, the extensive compatibility makes it a flexible choice for users looking to upgrade their cooling solutions.
Aesthetics and Lighting Features
When it comes to aesthetics, the Thermalright Frozen Notte 240 excels with its ARGB lighting features. Both the pump head and fans are equipped with synchronisable ARGB, allowing users to customise lighting effects directly from the motherboard. This feature not only enhances the visual appeal of a gaming setup but also provides a dynamic display that can match other components in the system.
In contrast, the Assassin X 120 SE, while efficient, does not offer the same level of visual flair. Its design focuses on functionality rather than aesthetics, which may appeal to users who prefer a more understated look. Therefore, for those looking to build an eye-catching rig, the Frozen Notte would be the better choice.
Price Consideration
The price difference between the two coolers is notable, with the Thermalright Assassin X 120 SE priced at C$24.29 and the Frozen Notte at C$62.90. This significant price gap reflects the different cooling technologies employed. The air cooler is an economical choice for budget-conscious consumers or those with less demanding cooling needs, while the water cooler justifies its higher price with superior cooling performance and advanced features.
While the Assassin X 120 SE is an excellent entry-level cooler, the Frozen Notte offers features and performance that cater to serious gamers and professionals willing to invest more for enhanced thermal management.
Which should you buy?
Choosing between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler ultimately depends on your specific needs. If you are looking for an affordable, compact cooling solution for a standard build, the Assassin X 120 SE is a solid option with its quiet operation and sufficient cooling capacity. However, if you require superior cooling for high-performance CPUs or plan to engage in intensive gaming or rendering tasks, the Frozen Notte’s advanced features and cooling capabilities make it worth the investment. Ultimately, evaluate your budget and performance requirements to make the best choice for your system.
