Overview of the Thermalright Assassin X 120R and AXP-120-X67

The Thermalright Assassin X 120R is priced at $22.90, making it about 30% cheaper than the Thermalright AXP-120-X67, which costs $32.59. Both coolers target performance enthusiasts looking for effective CPU cooling solutions, but they cater to slightly different needs based on form factor and cooling capabilities.

The Assassin X 120R features a 2000RPM PWM fan and four heat pipes, designed for optimal heat dissipation. In contrast, the AXP-120-X67 is a low-profile cooler with a height of just 67mm, making it a suitable choice for compact builds. Understanding these differences can help you choose the right cooler for your setup.

Design and Build Quality

When it comes to design, the Thermalright Assassin X 120R boasts a height of 151mm, providing ample cooling capabilities without compromising aesthetic appeal, thanks to its digital screen top cover. The combination of a performance-level fan and a visually appealing design makes it an attractive option for gamers and PC builders alike.

The AXP-120-X67, on the other hand, is designed with low-profile cases in mind. Its compact dimensions (123.5mm x 120mm x 67mm) allow it to fit into tighter spaces while maintaining a sleek appearance. Both coolers utilize high-quality materials, but the Assassin X 120R's larger size gives it a potential edge in heat dissipation.

Cooling Performance

Cooling performance is critical for any CPU cooler, and both the Assassin X 120R and AXP-120-X67 deliver impressive results. The Assassin X 120R features a fan speed of 2000RPM, while the AXP-120-X67 has a slightly lower fan speed of 1800RPM. This difference suggests that the Assassin X 120R may have a slight advantage in cooling efficiency, especially under heavy loads.

The AXP-120-X67 compensates for its lower RPM with its six heat pipes, which help distribute heat effectively. However, the Assassin X 120R's advanced AGHP heat pipe technology may offer superior performance by minimizing the impact of vertical and horizontal orientation. Ultimately, both coolers provide excellent cooling, but the Assassin X 120R may edge out in extreme scenarios.

Noise Levels

Noise levels are an essential consideration for users who prefer a quieter computing environment. The Thermalright Assassin X 120R is engineered to minimize noise with silicone corner pads around the fan, which help reduce vibrations. While specific noise levels aren’t provided, the design suggests that it aims for a quiet operation under load.

Conversely, the AXP-120-X67 has a maximum noise level of 26.1dB(A), which is relatively quiet for a CPU cooler. Given that both coolers use PWM fans, they will adjust their speeds based on temperature, helping to keep noise levels down during less demanding tasks. In a direct comparison, the AXP-120-X67 may be quieter at maximum load due to its optimized design.

Compatibility

Compatibility is a crucial factor for any CPU cooler, especially when considering different CPU sockets. The Thermalright Assassin X 120R supports a wide range of platforms, including AM4/AM5 and Intel LGA 1700, 1851, 1150, 1151, and 1200 sockets. This broad compatibility makes it a versatile choice for various builds.

Similarly, the AXP-120-X67 is compatible with multiple Intel and AMD sockets, including LGA 1700, 1150, 1151, 1851, 1200, and 2011/2066, as well as AM4. This extensive compatibility ensures that both coolers can cater to a wide audience. However, the low-profile design of the AXP-120-X67 positions it as a more suitable option for compact builds, while the Assassin X 120R is ideal for cases with more room.

Aesthetics and RGB Features

Aesthetics play a significant role in the choice of a CPU cooler, especially among gamers and custom PC builders. The Thermalright Assassin X 120R features ARGB lighting that syncs with the motherboard, allowing for impressive lighting effects. Its digital screen top cover adds a modern touch, making it appealing for users who value both performance and aesthetics.

The AXP-120-X67 also includes ARGB functionality and is designed to complement modern builds. However, it focuses more on functionality and compactness than flashy aesthetics. While both coolers offer RGB lighting, the Assassin X 120R's design and additional visual features may attract those who prioritize aesthetics.

Price Comparison

When it comes to pricing, the Thermalright Assassin X 120R is priced at $22.90, making it about 30% cheaper than the AXP-120-X67 at $32.59. This price difference could be a deciding factor for budget-conscious buyers. While both coolers deliver excellent performance, the Assassin X 120R provides a more cost-effective option without sacrificing quality.

The AXP-120-X67, while more expensive, offers a low-profile design suitable for compact builds. Buyers must consider whether the additional investment in the AXP-120-X67 aligns with their specific needs and build requirements.

Which should you buy?

Choosing between the Thermalright Assassin X 120R and the AXP-120-X67 ultimately depends on your specific needs. If you're looking for a cost-effective solution with superior cooling performance and aesthetics, the Assassin X 120R is the better option at $22.90. However, if you require a low-profile cooler for a compact build and are willing to spend a bit more, the AXP-120-X67 at $32.59 is an excellent choice. Both coolers deliver exceptional performance, but the right one for you hinges on your case size and budget considerations.
