Overview of Thermalright Products
When it comes to CPU cooling, Thermalright offers a range of solutions catering to different needs and preferences. In this comparison, we will examine the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalright Assassin King 120 SE ARGB CPU Air Cooler. Both products showcase the brand's commitment to quality and performance, but they target different segments of the market, with the AXP90 X47 priced at C$43.39 and the Assassin King 120 SE at a more budget-friendly C$24.59.
Design and Dimensions
The design of a CPU cooler can significantly affect its performance and compatibility. The AXP90 X47 features a compact height of just 47mm, making it an excellent choice for small form factor builds, such as HTPCs and ITX cases. In contrast, the Assassin King 120 SE stands taller at 148mm, designed for medium-sized computer cases. While the AXP90 X47 has dimensions of 94.5×95×47mm, the Assassin King measures 120×73×148mm. This difference means that users with limited space may find the AXP90 X47 more suitable, while those with larger cases can benefit from the enhanced cooling potential of the Assassin King.
Cooling Performance
Cooling performance is paramount for CPU coolers, and both models employ advanced technologies to tackle heat dissipation. The AXP90 X47 utilises 4×6mm heat pipes with AGHP technology, which enhances cooling efficiency by addressing inverse gravity effects. It has a maximum airflow of 42.58 CFM and operates at a noise level of 22.4 dB(A). The Assassin King 120 SE, on the other hand, takes advantage of 5×6mm heat pipes and boasts a higher maximum airflow of 66.17 CFM, making it potentially more effective for high-performance CPUs. However, it operates at a higher noise level of 25.6 dB(A), which may be a consideration for users seeking a quieter cooling solution.
Fan Features
Fan characteristics play a critical role in the overall operation of CPU coolers. The AXP90 X47 is equipped with a 92mm PWM fan that automatically adjusts speed according to temperature, providing a balance of performance and quiet operation. In contrast, the Assassin King 120 SE includes a larger 120mm PWM fan capable of reaching speeds up to 1550 RPM. This larger fan not only enhances cooling efficiency but also delivers vibrant ARGB lighting effects, making it an attractive choice for gamers and PC builders who enjoy aesthetic enhancements.
Compatibility
Both coolers offer broad compatibility with various CPU sockets, allowing users to choose based on their existing systems. The AXP90 X47 supports Intel LGA1700/1150/1151/1155/1156/1200 and AMD AM4/AM5 sockets. Conversely, the Assassin King 120 SE supports Intel 115X/1200/1700/17XX and AMD AM4/AM5 sockets as well. This makes both products versatile options for users upgrading or building their systems. However, the AXP90 X47’s low-profile design makes it particularly advantageous for smaller builds, where space and compatibility with RAM modules can be a concern.
Material and Build Quality
The build quality and materials used in CPU coolers can significantly impact their durability and performance. The AXP90 X47 features a radiator made of pure copper, which enhances oxidation resistance and overall thermal conductivity. This is complemented by the included high-quality heat transfer paste, ensuring efficient heat transfer from the CPU. Meanwhile, the Assassin King 120 SE utilises an aluminium heatsink, which is generally lighter but may not offer the same thermal performance as copper. Both products are designed with longevity in mind, but the AXP90 X47 may have a slight edge in thermal efficiency due to its copper construction.
Price Considerations
Price can be a deciding factor when selecting a CPU cooler. The AXP90 X47 is priced at C$43.39, which positions it as a premium offering in the low-profile segment. In contrast, the Assassin King 120 SE is considerably more affordable at C$24.59. This lower price point makes it an appealing option for budget-conscious consumers or those willing to compromise on size for better cooling performance. Ultimately, the choice between these two coolers may hinge on whether users prioritise budget or specific cooling capabilities.
Which should you buy?
Choosing between the Thermalright AXP90 X47 and the Thermalright Assassin King 120 SE depends largely on your specific needs and system configuration. If you are working with a compact build and require a low-profile cooler, the AXP90 X47 is an excellent choice, offering efficient cooling for smaller setups. However, if you have a medium-sized case and are looking for superior airflow and aesthetics, the Assassin King 120 SE stands out as a more affordable option with impressive cooling performance. Ultimately, consider your system's compatibility, noise preferences, and budget to make the best decision.
