Overview of the Thermalright Assassin X120 Refined SE CPU Air Cooler

The Thermalright Assassin X120 Refined SE CPU Air Cooler is priced at $17.90, making it a budget-friendly option in the CPU cooler market. With dimensions of 125mm x 71mm x 148mm, it boasts a robust design that includes four heat pipes and a TL-C12C PWM fan. This cooler is engineered for compatibility with various socket types for both AMD and Intel processors, including the latest AM4 and LGA 1700. Its AGHP technology ensures efficient heat dissipation, allowing for a maximum airflow of 66.17 CFM at a noise level of just 25.6 dB(A), which is relatively quiet for a cooler of its size.

Overview of the Thermalright AXP120-X67 Low Profile CPU Air Cooler

In contrast, the Thermalright AXP120-X67 Low Profile CPU Air Cooler is priced at $27.99, which makes it about 56% more expensive than the Assassin X120 Refined SE. This model is designed with a compact height of 67mm, making it suitable for smaller cases where space is a premium. It features six heat pipes and a TL-C12015 PWM fan that operates at a speed of 1800 RPM. The AXP120-X67 also supports a variety of AMD and Intel sockets, including LGA 1700 and AM4. Despite its quieter operation with a noise level of 26.1 dB(A), it provides a maximum airflow of 59 CFM, which is slightly less than the Assassin X120.

Design and Build Quality

The design and build quality of the Thermalright Assassin X120 Refined SE emphasize durability and performance. With an aluminum heatsink cover and metal fasteners, it weighs 0.645 kg (1.42 lb), reflecting a solid construction. The cooler's dimensions allow it to fit most medium-sized cases, while its heat pipes are designed to mitigate the effects of gravity on thermal performance. In comparison, the AXP120-X67 features an aluminum fin on a copper bottom and weighs slightly less, as it is designed for low-profile applications. At 120mm x 120mm x 67mm, it is more compact, which is advantageous for smaller builds. Each cooler is crafted to ensure effective cooling, but their designs cater to different user needs.

Cooling Performance

Cooling performance is critical when selecting a CPU cooler, and the Thermalright Assassin X120 Refined SE excels with its four heat pipes that utilize AGHP technology. This design allows it to efficiently handle heat dissipation, achieving a maximum airflow of 66.17 CFM, which is beneficial for demanding tasks. The cooler operates at a maximum noise level of 25.6 dB(A), providing a quiet computing experience. On the other hand, the AXP120-X67, with its six heat pipes, aims for a high cooling performance in a compact form factor. However, it achieves a lower airflow of 59 CFM and operates at a slightly higher noise level of 26.1 dB(A). While both coolers perform well, the Assassin X120 offers better airflow, making it more suitable for high-performance systems.

Compatibility and Installation

Both the Thermalright Assassin X120 and AXP120-X67 are designed for broad compatibility with various Intel and AMD sockets. The Assassin X120 supports multiple Intel sockets, including LGA 1150 through 1700, as well as AMD AM4 and AM5. This makes it highly versatile for users upgrading or building new systems. The AXP120-X67 also supports a wide range of sockets but is specifically optimized for low-profile installations. Both coolers come equipped with the necessary metal fasteners for installation, ensuring a straightforward setup process. However, users looking for flexibility in building larger systems might find the Assassin X120 more appealing.

Noise Levels

When it comes to noise levels, the Thermalright Assassin X120 Refined SE offers a quieter operation at 25.6 dB(A), making it an excellent choice for users who prioritize a silent computing environment. This low noise level is achieved through its efficient PWM fan design, which can provide strong cooling performance without excessive sound. Meanwhile, the AXP120-X67 operates at 26.1 dB(A), which is slightly louder but still falls within an acceptable range for most users. Both coolers are designed to minimize noise while delivering adequate cooling, but the Assassin X120 has a slight edge in quiet operation.

Price Comparison

The price difference between the two coolers is notable, with the Thermalright Assassin X120 priced at $17.90 and the AXP120-X67 at $27.99. This means that the AXP120-X67 is approximately 56% more expensive than the Assassin X120. For budget-conscious users, the Assassin X120 offers exceptional value without compromising on essential features like cooling performance and compatibility. Conversely, the AXP120-X67 justifies its higher price with its low-profile design and additional heat pipes, appealing to those who need a compact solution for tighter spaces.

Which should you buy?

Ultimately, the choice between the Thermalright Assassin X120 Refined SE and the AXP120-X67 depends on your specific needs and budget. If you are seeking an affordable, high-performing CPU cooler that excels in airflow and noise levels, the Assassin X120 is the better option at $17.90. However, if you require a low-profile cooler for compact builds and are willing to invest a bit more for that convenience, the AXP120-X67 at $27.99 may be worth the extra cost.
