Overview of the Thermalright AXP120-X67
The Thermalright AXP120-X67 Low Profile CPU Air Cooler is available for $27.99, presenting a more compact solution with a total height of only 67mm. It features six heat pipes and a 120mm PWM fan that operates at a speed of 1800 RPM, delivering a maximum airflow of 59 CFM. While it has a slightly higher noise level of 26.1 dB(A), its low-profile design makes it ideal for smaller cases or setups where height clearance is a concern.
The AXP120-X67 is built with quality materials, including aluminum fins on a copper base, ensuring effective heat dissipation. It also supports a wide range of Intel and AMD sockets, making it a flexible choice for various builds. With its innovative AGHP technique, it effectively combats the inverse gravity effect, ensuring consistent performance regardless of orientation.
Cooling Performance
In terms of cooling performance, the Assassin X 120R SE V2 has an advantage with its higher airflow rating of 66.17 CFM compared to the AXP120-X67's 59 CFM. This difference can be crucial in scenarios where high thermal loads are expected, such as gaming or heavy multitasking. Additionally, the Assassin X 120R operates at a lower noise level of 25.6 dB(A), making it the quieter option.
On the other hand, the AXP120-X67, while slightly less powerful in airflow, compensates with its advanced heat pipe technology designed to maintain efficiency in compact spaces. The choice between these two may come down to the specific cooling requirements of the CPU and the case configuration.
Installation and Compatibility
Both coolers are designed for easy installation and broad compatibility with various Intel and AMD sockets. The Assassin X 120R SE V2 includes metal fasteners to accommodate AMD AM4 and AM5, and Intel LGA 1150 through 1851. This ensures that users can install the cooler with relative ease, aided by included instructions and installation videos.
The AXP120-X67 also supports a wide range of sockets, including Intel LGA 1700 and AMD AM4, affirming its flexibility. However, its design specifically targets lower-profile cases, making it the go-to choice for builds where space is at a premium. Users should consider their specific system requirements when evaluating installation ease and compatibility.
Noise Levels
When it comes to noise levels, the Assassin X 120R SE V2 is the quieter option, operating at 25.6 dB(A), which is almost silent in practical use. This makes it suitable for environments where noise can be a distraction, such as home offices or gaming spaces.
Conversely, the AXP120-X67 has a marginally higher noise level at 26.1 dB(A). While this difference is minimal, it could be noticeable in particularly quiet setups. Users prioritizing a silent operation would likely prefer the Assassin X 120R SE V2 for its superior noise performance.
Design and Aesthetics
Design-wise, the Assassin X 120R SE V2 features a visually appealing RGB PWM fan that adds a modern touch to any build. The RGB lighting can enhance the overall look of a gaming setup, making it a popular choice among PC enthusiasts who value aesthetics alongside performance.
In contrast, the AXP120-X67 has a more understated design, which may appeal to users seeking a clean and minimalist look. Although it lacks RGB lighting, its low-profile structure can fit seamlessly into smaller cases without overpowering other components. Ultimately, design preference will depend on individual taste and the overall theme of the user's build.
Price Comparison
The Assassin X 120R SE V2 is priced at $16.59, making it about 40% cheaper than the AXP120-X67, which retails for $27.99. This significant price difference can be a deciding factor for budget-conscious consumers looking for effective cooling solutions without breaking the bank.
While the AXP120-X67 offers advanced features and a compact design that may justify its higher price, the affordability of the Assassin X 120R SE V2 makes it an attractive option for those who want reliable cooling performance at a lower cost.
Which should you buy?
