Overview of Thermalright Peerless Assassin 120 SE V2 and Thermalright AXP120-X67

The Thermalright Peerless Assassin 120 SE V2 is a powerful CPU cooler priced at C$54.90, while the Thermalright AXP120-X67 is a low-profile option available for C$36.90. Both coolers are designed to provide efficient cooling solutions, but they target different needs and form factors within the PC cooling market.

The Peerless Assassin 120 SE V2 boasts a larger footprint and higher cooling capacity, making it ideal for high-performance systems. In contrast, the AXP120-X67 caters to compact builds, offering decent cooling in a smaller height of just 67mm. Understanding these distinctions will help users select the cooler that best fits their specific requirements.

Cooling Performance

The Peerless Assassin 120 SE V2 is engineered for extreme CPU cooling performance, with a TDP of up to 265 watts, thanks to its advanced AGHP GEN 5.0 technology and six 6mm heat pipes. This makes it a formidable choice for overclocked CPUs or demanding applications.

On the other hand, the AXP120-X67, while still effective, is rated for lower TDP applications. Its six 6mm heat pipes and PWM fan technology also contribute to its cooling efficiency, but with a maximum airflow of 59 CFM and a fan speed of 1800 RPM, it may not match the raw cooling power of the Peerless Assassin. This distinction is crucial for users who plan to push their CPUs to the limit.

Design and Dimensions

The Thermalright Peerless Assassin 120 SE V2 measures 125mm x 135mm x 155mm, making it a substantial cooler that requires adequate clearance in the case. The design features an aluminum fin structure coupled with a copper base, enhancing thermal conductivity and heat dissipation.

In comparison, the AXP120-X67 is significantly more compact at 123.5mm x 120mm x 67mm. This low-profile design is particularly advantageous for smaller cases or builds with limited vertical space. While both models utilise aluminum and copper, the Peerless Assassin's larger dimensions provide a greater surface area for heat dissipation, which can be a deciding factor for users with specific case constraints.

Noise Levels

When it comes to noise, the Thermalright Peerless Assassin 120 SE V2 operates at a noise level of up to 29.5 dB(A) at maximum fan speed. This level is relatively quiet, ensuring that users do not have to contend with excessive noise during operation, even under load.

Conversely, the AXP120-X67 is designed with a slightly quieter maximum noise level of 26.1 dB(A). This advantage could make it a more appealing choice for users focused on silence, especially in home or office environments. Understanding these noise characteristics can be pivotal for users who prioritise a quiet computing experience.

Compatibility

The Peerless Assassin 120 SE V2 supports a wide range of CPU sockets, including Intel LGA 1851/1700/1200/115X and AMD AM4/AM5. This extensive compatibility ensures that it can be used with a variety of modern processors, making it a versatile choice for many builds.

The AXP120-X67 also offers solid compatibility, supporting Intel sockets 1700/1150/1151/1155/1156/1200/2011/2066 and AMD AM4. While both coolers accommodate a range of platforms, the Peerless Assassin's broader support for newer sockets might make it a better long-term investment for users looking to upgrade their systems over time.

Installation Process

Both the Thermalright Peerless Assassin 120 SE V2 and AXP120-X67 come equipped with metal fasteners for installation, facilitating a straightforward setup on both Intel and AMD platforms. The Peerless Assassin includes installation instructions for various CPU slot platforms, which can simplify the process for less experienced builders.

The AXP120-X67, with its low-profile design, may also be relatively easy to install, especially in tight spaces. However, users should consider their specific case dimensions and CPU socket type before choosing, as the installation experience can vary based on individual setups.

Price Comparison

At a current price of C$54.90, the Thermalright Peerless Assassin 120 SE V2 is positioned as a premium option within the CPU cooler market. This pricing reflects its high-performance capabilities and advanced features.

In contrast, the AXP120-X67 is significantly more budget-friendly at C$36.90, making it an attractive option for users who need efficient cooling without breaking the bank. While the price difference is substantial, users need to weigh the additional features and cooling performance of the Peerless Assassin against the cost savings offered by the AXP120-X67.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Thermalright AXP120-X67 ultimately depends on your specific needs and system requirements. If you are building a high-performance gaming rig or workstation that demands superior cooling, the Peerless Assassin's advanced technology and higher TDP support make it the better choice. However, for users with compact builds or those prioritising budget and quieter operation, the AXP120-X67 offers excellent performance in a more affordable and space-saving package.
