Overview of Thermalright Peerless Assassin 120 SE V3
The Thermalright Peerless Assassin 120 SE V3 CPU Air Cooler is available for $35.90, making it about 4.4% more expensive than the Mini Black version. It boasts a double-tower, dual-fan structure that enhances heat dissipation efficiency significantly. Each of its two PWM fans can reach speeds of up to 2000 RPM, delivering an impressive airflow of 70.84 CFM. The operating noise level is slightly higher than the Mini at 29.8 dB(A).
With six heat pipes and an advanced AGHP technology, this cooler efficiently addresses thermal challenges in a dual-platform setup, supporting both Intel and AMD sockets. The SE V3 also features a sleek aluminium heatsink cover, making it not only functional but visually striking. This cooler is tailored for users who may require more robust cooling solutions in larger builds.
Heat Dissipation Performance
When comparing heat dissipation capabilities, the SE V3 clearly takes the lead. With its dual-fan setup and a maximum fan speed of 2000 RPM, it achieves an airflow of 70.84 CFM, compared to the Mini Black's 66.87 CFM. This additional airflow can be crucial for high-performance CPUs under heavy loads, ensuring temperatures remain in check during demanding tasks.
Both coolers utilize AGHP technology, which helps mitigate the effects of gravity on thermal performance, but the SE V3's design allows for better heat distribution across its larger surface area, thanks to the dual towers. This effectively enhances its overall heat dissipation efficiency, making it the better choice for users with high thermal demands.
Compatibility with CPU Sockets
In terms of compatibility, both coolers excel in supporting a wide range of CPU sockets. The Mini Black supports Intel LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, along with AMD AM4 and AM5. Meanwhile, the SE V3 matches this compatibility but also includes enhancements for the latest Intel and AMD processors, making it suitable for future-proofing builds.
The SE V3’s versatile mounting accessories allow it to be installed on various motherboard configurations, which can be a significant advantage for users planning upgrades. This broader compatibility range ensures that the SE V3 can cater to a wider audience, including those looking to build high-end systems.
Noise Levels
When it comes to noise levels, the Mini Black operates at a quieter maximum of 25.6 dB(A) compared to the SE V3's 29.8 dB(A). This difference of about 4.2 dB(A) might be negligible for some users, but for those who prefer a quieter environment, the Mini Black could be the better choice.
However, it's important to note that the SE V3's higher fan speed and airflow come with a corresponding increase in noise output. Users who prioritize performance over noise may find the SE V3 acceptable, especially given its superior cooling capabilities.
Aesthetics and Build Quality
Aesthetically, both coolers are designed with a sleek, modern look. The Mini Black features a fully blackened body with an antioxidant coating, enhancing its durability and visual appeal. In contrast, the SE V3 showcases a more intricate design with a double-tower structure and a matte finish that adds to its sophistication.
Both coolers are constructed from high-quality aluminium and feature carefully designed heat pipes, but the SE V3's dual-fan setup and larger size give it a more robust appearance. This could make it more appealing for users who want their cooling solution to stand out in their build.
Price Comparison
The Thermalright Peerless Assassin 120 Mini Black is priced at $34.39, while the SE V3 costs $35.90. This makes the Mini Black about $1.51 cheaper, which is a notable difference for budget-conscious consumers. While the price difference is relatively small, it may influence decisions for users who are looking for effective cooling solutions without breaking the bank.
Considering the performance features and the cooling efficiency differences, the SE V3 may justify its higher price for users who need enhanced cooling capabilities. However, for everyday users or those with moderate cooling needs, the Mini Black presents a solid value option.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Mini Black and the Thermalright Peerless Assassin 120 SE V3 depends on your specific needs. If you prioritize a quieter operation and a lower price, the Mini Black is the better option, presenting a commendable balance of performance and noise management. However, if your setup demands more substantial cooling performance for high-end CPUs, the SE V3's dual-fan system and improved heat dissipation make it worth the extra investment. Ultimately, both coolers provide excellent value in their respective categories, but your choice should align with your cooling requirements and budget constraints.
