Overview of Thermalright AXP90 X47 Black and Peerless Assassin 120 SE

The Thermalright AXP90 X47 Black is priced at $22.39, while the Peerless Assassin 120 SE is significantly higher at $49.99, making the AXP90 about 55% cheaper. This price difference may be a critical factor for budget-conscious consumers. However, the two coolers cater to different needs within the CPU cooler market, reflecting their distinct designs and intended use cases.

The AXP90 X47 Black is a low-profile cooler designed specifically for compact ITX builds, supporting a variety of Intel and AMD sockets. In contrast, the Peerless Assassin 120 SE boasts a dual-fan setup and six heat pipes, targeting users who require more robust cooling performance for larger builds. Understanding these differences can guide potential buyers toward the cooler that best fits their requirements.

Design and Aesthetics

In terms of design, the Thermalright AXP90 X47 Black is compact, measuring just 47mm in height. This low-profile design is ideal for small form factor cases where space is at a premium. Its sleek black finish, combined with the slim 92mm TL-9015B PWM fan, offers a modern aesthetic that appeals to many users.

On the other hand, the Peerless Assassin 120 SE features a more substantial design, with dimensions of 125mm x 135mm x 155mm. Its dual 120mm PWM fans and six heat pipes not only enhance thermal performance but also create a visually striking presence inside a PC case. Users looking for a cooler that stands out might prefer the Peerless Assassin's robust appearance, while those needing a more discreet option may lean towards the AXP90.

Cooling Performance

Cooling performance is a key consideration when selecting a CPU cooler. The Thermalright AXP90 X47 Black is equipped with four 6mm heat pipes and has a noise level of up to 22.4 dBA, striking a balance between performance and noise. It is designed for low thermal resistance, making it suitable for moderate cooling needs.

In contrast, the Peerless Assassin 120 SE is engineered for higher performance, featuring six heat pipes and two PWM fans that can reach speeds of 1550 RPM. This setup allows it to achieve an airflow of 66.17 CFM (maximum), providing superior cooling for overclocked CPUs and demanding workloads. For users with high-performance systems, the Peerless Assassin offers a significant advantage in cooling capacity.

Compatibility

Compatibility is another vital factor when choosing a CPU cooler. The Thermalright AXP90 X47 Black supports a wide range of sockets, including Intel's 115X/1200 series and AMD's AM4/AM5 platforms. Its all-metal platform with a backplate fastener ensures reliable installation across various systems, particularly in compact builds.

The Peerless Assassin 120 SE also supports multiple Intel and AMD sockets, including the latest LGA 1700, 1150, 1151, 1200, and AMD's AM4/AM5. However, it requires the original motherboard’s built-in backplane for installation, which some users may find less convenient. Both coolers offer excellent compatibility, but the AXP90’s design may provide an easier installation process for smaller cases.

Noise Levels

When it comes to noise levels, the Thermalright AXP90 X47 Black operates at a maximum of 22.4 dBA, making it a quiet option for users who prioritize a noise-free environment. This low noise output is particularly beneficial for those who use their systems for tasks that require concentration, such as gaming or content creation.

In comparison, the Peerless Assassin 120 SE has a slightly higher maximum noise level of 25.6 dBA. While still relatively quiet, the dual-fan design may produce more sound under load compared to the AXP90. Users sensitive to noise should consider these levels, especially in quiet settings.

Installation Process

The installation process can vary significantly between the two coolers. The Thermalright AXP90 X47 Black features a streamlined installation method, utilizing an all-metal platform and backplate fastener. This design simplifies the setup, making it accessible even for novice builders, especially in tight spaces.

Conversely, the Peerless Assassin 120 SE’s installation may require more effort due to its size and the need to use the motherboard's built-in backplane for AMD installations. While it provides strong performance, the complexity in installation might deter some users, particularly those new to PC building.

Price-to-Performance Ratio

The Thermalright AXP90 X47 Black offers an impressive price-to-performance ratio, coming in at just $22.39. For users with basic cooling needs or who are building a compact system, the AXP90 delivers solid performance without breaking the bank. This makes it an attractive option for budget-conscious buyers or those focused on simplicity.

On the flip side, the Peerless Assassin 120 SE, priced at $49.99, is aimed at users who are willing to invest more for enhanced cooling capabilities. Its advanced design and dual-fan configuration justify the higher price point for those seeking superior thermal performance. However, for users with less demanding cooling needs, the AXP90’s value is hard to ignore.

Which should you buy?

Choosing between the Thermalright AXP90 X47 Black and the Peerless Assassin 120 SE ultimately depends on your specific needs. If you are working with a compact ITX build or require a budget-friendly option, the AXP90 X47 Black’s low profile and affordability make it a strong contender. However, for users with larger systems who prioritize high-performance cooling and are comfortable with a higher price point, the Peerless Assassin 120 SE offers superior cooling capabilities and aesthetic appeal. Evaluate your system requirements and budget to make an informed decision that best suits your PC build.
