Overview of the Thermalright Assassin X 120R and AXP90 X47

The Thermalright Assassin X 120R is priced at $22.90, while the AXP90 X47 is slightly cheaper at $22.39, making it about 2.2% more affordable. Both CPU coolers are designed to cater to different needs, with the Assassin X 120R focusing on performance and aesthetics, and the AXP90 X47 emphasizing a compact design for smaller builds.

Design and Build Quality

The Thermalright Assassin X 120R features a robust design with a height of 151mm, allowing it to fit in most cases without compromising on heat dissipation. It is equipped with a digital screen top cover that adds a modern touch to its aesthetic appeal. In contrast, the AXP90 X47 showcases a low-profile design with a total height of just 47mm, making it ideal for ITX builds where space is at a premium. Both coolers are built with quality materials; however, the AXP90 X47 utilizes a black nickel plating process, enhancing its durability against corrosion.

Cooling Performance

When it comes to cooling performance, the Assassin X 120R stands out with its 2000RPM PWM fan, which can adjust speed based on the motherboard's temperature. This feature is coupled with four 6mm heat pipes that utilize AGHP technology for better thermal conductivity. On the other hand, the AXP90 X47 also incorporates four 6mm heat pipes but operates at a lower noise level of 22.4 DBA. While both coolers are effective, the Assassin X 120R is likely to provide superior cooling performance due to its higher RPM and larger fan size.

Compatibility

The Thermalright Assassin X 120R is compatible with a wide range of sockets, including AM4, AM5, and Intel LGA1700/1851/1150/1151/1200. This broad compatibility makes it a versatile choice for various builds. Meanwhile, the AXP90 X47 supports similar socket types such as AMD AM4/AM5 and Intel 1150/1151/1155/1851/1200/1700. While both products cover a wide array of setups, the Assassin X 120R's extra height may limit its compatibility with smaller cases, whereas the AXP90 X47 excels in compact environments.

Noise Levels

Noise levels are an essential consideration for users who prefer a quieter operation. The AXP90 X47 operates at a maximum noise level of 22.4 DBA, which is relatively silent for a CPU cooler. The Assassin X 120R, while not specified for its noise level, features silicone corner pads designed to reduce noise from fan rotation. Given its higher RPM, the Assassin X 120R may produce more noise than the AXP90 X47, making the latter the better option for noise-sensitive environments.

Aesthetic Appeal

Aesthetics play a crucial role in modern PC builds, and the Thermalright Assassin X 120R excels in this area with its ARGB lighting that syncs with the motherboard's 5V 3-pin. This feature allows for a customizable lighting experience that can enhance the overall look of a build. In contrast, the AXP90 X47 lacks RGB lighting but offers a sleek, understated look that may appeal to users who prefer a more classic design. The choice between the two ultimately comes down to personal preference regarding aesthetics.

Pricing and Value

The Assassin X 120R is priced at $22.90, while the AXP90 X47 comes in at $22.39, making the AXP90 X47 about 2.2% cheaper. Despite the small price difference, both coolers offer good value for their respective features. The performance of the Assassin X 120R may justify its higher price for users seeking maximum cooling efficiency, while the AXP90 X47 provides a compact and quieter option at a slightly lower cost.

Which should you buy?

Choosing between the Thermalright Assassin X 120R and the AXP90 X47 ultimately depends on your specific needs. If you require superior cooling performance and aesthetically pleasing features like ARGB lighting, the Assassin X 120R is the right choice. However, if you are looking for a compact, quieter cooler that fits easily into smaller cases, the AXP90 X47 is the better option. Consider your build's requirements, budget, and personal preferences to make the best decision.
