Overview of the Thermalright Peerless Assassin 120 SE V2 CPU Cooler

The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is priced at $38.99, making it a solid choice for gamers and multitaskers looking for efficient cooling. This dual tower cooler features six heat pipes and dual 120mm PWM fans that can reach up to 1850 RPM. Its design not only enhances heat dissipation but also supports a wide range of platforms, including AMD AM4/AM5 and Intel LGA1851/1700. With a noise level of 29.5 dBA, it strikes a balance between performance and quiet operation.

Overview of the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler

The Thermalrlght Peerless Assassin 120 SE CPU Air Cooler is available for $32.90, making it approximately 17% cheaper than its counterpart. This cooler also features six heat pipes and dual 120mm TL-C12C PWM fans, but operates at a slightly lower maximum speed of 1550 RPM. Its aluminum heatsink cover and AGHP technology provide excellent thermal performance, while its offset asymmetric layout improves compatibility with various graphics cards and motherboards. This cooler maintains a lower noise level of 25.6 dBA, ensuring a quieter environment.

Cooling Performance Comparison

The Thermalright Peerless Assassin 120 SE V2 offers superior cooling performance due to its higher fan RPM of 1850, which results in an airflow of 88.89 CFM. This higher airflow can be particularly beneficial during intense gaming sessions or demanding workloads. In contrast, the Thermalrlght Peerless Assassin 120 SE operates at a maximum airflow of 66.17 CFM. While both coolers utilize six heat pipes, the higher RPM of the V2 model translates to better heat dissipation capabilities, making it a stronger option for users prioritizing cooling efficiency.

Design and Build Quality

Both coolers boast a dual tower design, which enhances heat transfer efficiency compared to traditional single-tower coolers. The Thermalright Peerless Assassin 120 SE V2 features a copper base with nickel plating, providing a robust thermal interface. The Thermalrlght Peerless Assassin 120 SE, on the other hand, utilizes an anodized brushed black top cover along with aluminum and copper materials. This difference in materials and design contributes to a distinct aesthetic, with the V2 model being slightly bulkier due to its dual tower configuration. Each cooler is designed for compatibility with a range of AMD and Intel sockets, though users must ensure their cases can accommodate the larger sizes.

Noise Levels and Operating Conditions

When it comes to noise levels, the Thermalrlght Peerless Assassin 120 SE operates at a quieter 25.6 dBA compared to the V2's 29.5 dBA. For users who prioritize a quieter computing experience, the SE model may be the better choice. However, the difference in noise levels is minimal, especially under load when both coolers are likely to ramp up fan speeds. The V2's higher RPM may contribute to slightly more noise, but it also compensates for this with its superior cooling performance.

Compatibility and Installation

Both coolers support a wide range of AMD and Intel platforms, including AMD AM4/AM5 and Intel LGA 1700. The Thermalright Peerless Assassin 120 SE V2 is straightforward to install, while the SE model includes a specific installation system and metal pressure plate for improved CPU contact. This attention to detail in the installation process can lead to better thermal performance, particularly for users who may not be as experienced with cooler installations. However, both coolers require users to check compatibility with their cases and motherboards, especially given their larger size.

Pricing and Value

In terms of pricing, the Thermalrlght Peerless Assassin 120 SE is priced at $32.90, making it a more budget-friendly option than the Thermalright Peerless Assassin 120 SE V2 at $38.99. This price difference of $6.09 may appeal to users looking for an effective cooler without breaking the bank. However, potential buyers should consider whether the additional cooling performance of the V2 justifies the higher price, especially for high-performance builds where thermal management is crucial.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Thermalrlght Peerless Assassin 120 SE ultimately depends on your specific needs and priorities. If cooling performance is your primary concern, the V2 offers superior airflow and thermal efficiency, making it ideal for gaming and high-load applications. However, if budget and noise level are more significant factors, the SE provides excellent value with quieter operation and lower cost. Each cooler has its strengths, so consider your system requirements and preferences before making a decision.
