Dimension comparison
Price Comparison
The Thermalright AXP90-X47 is priced at £41.90, while the TR-Assassin X 120R SE V2 is significantly more affordable at £14.49. The price differential of £27.41 may be a crucial factor for budget-conscious consumers. Despite the price disparity, each cooler offers unique features that cater to different user needs.
The Thermalright AXP90-X47 positions itself as a premium low-profile solution, ideal for compact builds, whereas the TR-Assassin X 120R SE V2 offers robust performance at a more accessible price point. This makes the TR-Assassin an attractive option for those who may not require the specific advantages of the AXP90-X47.
Design and Dimensions
The dimensions of the Thermalright AXP90-X47 are 94.5×95×47mm, making it a compact choice for small form factor builds. In contrast, the TR-Assassin X 120R SE V2 measures 120x71x148mm. While the AXP90-X47 is specifically designed for low-profile applications, the larger size of the TR-Assassin allows for potentially better cooling performance due to its greater surface area.
The 47mm height of the AXP90-X47 is particularly advantageous for users with limited space, as it can fit into tighter cases without obstructing other components. The TR-Assassin’s height of 148mm is more suited for standard ATX cases, which means it may not fit in smaller setups.
Cooling Performance
Cooling performance is a vital aspect of any CPU cooler, and both products excel in this area, albeit in different contexts. The Thermalright AXP90-X47 features a maximum air volume of 42.58 CFM and operates at a noise level of 22.4dB. Its design includes 4 heat pipes that utilise AGHP technology, enhancing cooling efficiency.
On the other hand, the TR-Assassin X 120R SE V2 boasts a higher maximum airflow of 66.17 CFM, which can lead to improved cooling performance in larger cases. However, it operates at a slightly higher noise level of 25.6dB. Users who prioritise quiet operation may prefer the Thermalright, while those seeking superior airflow might lean towards the TR-Assassin.
Fan Specifications
The fan specifications differ notably between the two coolers. The Thermalright AXP90-X47 incorporates a TL-9015R fan that spins at a maximum speed of 2700 RPM, contributing to its efficient cooling capabilities. This fan operates quietly, maintaining a noise level of only 22.4dB, making it suitable for environments where noise is a concern.
In contrast, the TR-Assassin X 120R SE V2 is equipped with a TL-C12C-L V2 fan, which operates at a lower maximum speed of 1550 RPM. While this results in a slightly quieter operation, the trade-off is lower airflow performance compared to the AXP90-X47. Users must consider whether they prioritise higher airflow or quieter operation when choosing between these two models.
Compatibility
Compatibility is essential when selecting a CPU cooler. The Thermalright AXP90-X47 supports a wide range of Intel sockets, including LGA 1700, 1851, and 1200, as well as AMD AM4 and AM5. Its low-profile design is especially beneficial for users with small cases, ensuring no memory limitations.
The TR-Assassin X 120R SE V2 also supports various Intel and AMD sockets, including LGA1150 to 1700 and AM4/AM5. However, it requires the original motherboard’s backplate for installation on AM4 and AM5, which might complicate the installation process for some users. Both coolers offer broad compatibility, but the AXP90-X47’s ease of installation in compact builds may be more appealing.
Noise Levels
Noise levels are a critical consideration for many PC builders. The Thermalright AXP90-X47 operates at a maximum noise level of 22.4dB, making it one of the quieter options available. This low noise level is a significant advantage for users who prefer a silent computing environment.
Conversely, the TR-Assassin X 120R SE V2 has a maximum noise level of 25.6dB. While this is still relatively quiet, it may be noticeable in a noise-sensitive setup. The Thermalright’s quieter operation could be a deciding factor for those prioritising a serene computing experience.
Thermal Management Technology
The thermal management technology varies between the two coolers. The Thermalright AXP90-X47 features advanced AGHP technology, employing 4 heat pipes that enhance heat dissipation through secondary welding. This innovative design helps mitigate the inverse gravity effect, ensuring efficient cooling regardless of the cooler's orientation.
The TR-Assassin X 120R SE V2, while not boasting the same advanced technology, offers a solid design with an aluminium and copper heatsink. Its SS2 installation system enhances contact with the CPU, thereby improving overall thermal management. While both coolers are effective, the AXP90-X47’s superior technology may provide better thermal performance in critical situations.
Which should you buy?
Choosing between the Thermalright AXP90-X47 and the TR-Assassin X 120R SE V2 largely depends on your specific needs and setup. If you require a compact, low-profile cooler that operates quietly and is ideal for small form factor builds, the AXP90-X47 is the clear winner at £41.90. However, if you're looking for a more budget-friendly option with higher airflow and flexibility in larger cases, the TR-Assassin X 120R SE V2 at £14.49 is a fantastic choice.
Ultimately, consider your case size, budget, and cooling requirements before making a decision. Both coolers have their unique strengths, catering to different segments of the market effectively.
