Dimension comparison
Overview of Thermalright Peerless Assassin 120 SE CPU Cooler
The Thermalright Peerless Assassin 120 SE CPU Cooler is priced at $49.99 and is designed to deliver effective cooling for a range of processors. It features a dual tower design with six heat pipes and utilizes AGHP technology, enhancing its cooling efficiency. The cooler comes equipped with two 120mm PWM fans that operate at a speed of 1550 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of 25.6 dBA. This cooler is compatible with both AMD AM4/AM5 and Intel LGA 1700/1150/1151/1200/1851 sockets, making it versatile for various builds.
Overview of Thermalright Peerless Assassin 120 SE V2 CPU Cooler
The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is the more budget-friendly option at $38.99, offering similar cooling capabilities with some enhancements. This model also features a dual tower design and six heat pipes, but its dual 120mm PWM fans can reach a higher speed of 1850 RPM, providing an airflow of 88.89 CFM. This cooler supports both AMD AM4/AM5 and Intel LGA 1851/1700 platforms, making it a practical choice for modern desktop builds. Its design aims to improve heat transfer efficiency, providing stable thermal performance even under high-load scenarios.
Cooling Performance Comparison
When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE V2 outshines its predecessor. With a maximum fan speed of 1850 RPM compared to the 1550 RPM of the original model, the V2 version is likely to dissipate heat more effectively. The airflow of 88.89 CFM from the V2 is almost 34% higher than the 66.17 CFM from the original model, which can significantly improve cooling during demanding tasks such as gaming or multitasking. Therefore, for users prioritizing performance, the V2 offers a notable advantage.
Noise Levels and Operational Efficiency
In terms of noise levels, the Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dBA, making it relatively quiet during operation. The V2, however, has a higher noise level of 29.5 dBA, which might be noticeable in quieter environments. While the increased fan speed of the V2 enhances cooling, it comes at the cost of slightly higher noise levels. Users who value a quieter operation may prefer the original 120 SE model, whereas those looking for maximum cooling efficiency might lean towards the V2 despite the increased noise.
Compatibility and Installation
Both coolers are designed to be compatible with a wide range of CPU sockets, including AMD AM4/AM5 and Intel LGA 1700/1150/1151/1200/1851 for the original model, and LGA 1851/1700 for the V2. Each cooler includes the necessary mounting hardware for easy installation. However, the original model specifies that users must utilize their motherboard's built-in backplane for AMD installations, which is not included with the cooler. This could pose a challenge for some users, making the V2's straightforward compatibility an attractive feature.
Price Comparison and Value
The Thermalright Peerless Assassin 120 SE is priced at $49.99, while the Thermalright Peerless Assassin 120 SE V2 comes in at $38.99, making the V2 about 17% cheaper. For budget-conscious consumers, this price difference can be significant, especially considering that the V2 offers enhanced cooling capabilities. However, if users are willing to spend a bit more for potentially quieter operation and proven technology, the original model may still be appealing.
Design and Aesthetics
Both coolers boast a dual tower design and a similar aesthetic that fits well in most builds. The original Thermalright Peerless Assassin 120 SE features a more straightforward cooling solution, while the V2's design aims to optimize heat dissipation. Although both models maintain a professional look, the V2 might attract those looking for modern enhancements in their cooling solutions. The choice between them may ultimately come down to personal preference regarding design aesthetics.
Which should you buy?
When deciding between the Thermalright Peerless Assassin 120 SE and the Thermalright Peerless Assassin 120 SE V2, it ultimately comes down to your specific needs and priorities. If you are looking for better cooling performance and are willing to accept a slightly noisier operation, the V2 is the better option at a lower price point of $38.99. However, if you prefer a quieter cooler and are okay with spending a bit more for potentially more reliable technology, the original model priced at $49.99 may be worth considering. Each cooler has its strengths, making them solid choices within the thermal management market.
