Overview of the Delta A40 ARGB CPU Cooler

The Delta A40 ARGB CPU Cooler is designed for users looking for an efficient air cooling solution with a touch of personalization. Priced at C$19.29, this cooler supports up to 220W power dissipation, making it suitable for both gaming and creative tasks. Its standout feature is the customizable ARGB lighting, allowing users to tailor the visual aesthetics of their setup.

The cooler features a unique family fin array design that reduces wind resistance and enhances heat dissipation. It is equipped with a 120mm PWM silent cooling fan, capable of delivering an airflow of 73 CFM while maintaining noise levels at or below 29 dB(A). The Delta A40 is compatible with a variety of Intel and AMD platforms, making it a versatile choice for many builds.

Overview of the Thermalright Peerless Assassin 120 SE V2 CPU Cooler

The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is a high-performance cooling solution priced at C$54.90. This cooler is engineered for extreme CPU cooling performance, supporting a thermal design power (TDP) of up to 265W. This makes it an excellent choice for overclockers or users with demanding workloads.

Featuring dual thickened PWM fans, the cooler can achieve an airflow of 88.19 CFM at a maximum fan speed of 1850 RPM. The noise level is comparable to its competitor, at or below 29.5 dB(A). Built with a combination of aluminum fins and a pure copper base, the Peerless Assassin is also designed for compatibility with a wide range of Intel and AMD sockets.

Performance Comparison

When it comes to performance, the Thermalright Peerless Assassin outshines the Delta A40 with a maximum TDP of 265W compared to the latter's 220W. This means the Peerless Assassin can handle more intensive tasks and higher thermal loads, making it a better option for high-performance CPUs or overclocking scenarios.

In terms of airflow, the Peerless Assassin again takes the lead with 88.19 CFM compared to the Delta A40's 73 CFM. While both coolers operate at comparable noise levels, the additional airflow and higher power handling of the Peerless Assassin contribute to more efficient cooling, particularly under load.

Design and Aesthetics

The Delta A40 ARGB CPU Cooler features a distinct design with circular elements and a mirror-like finish, appealing to users who value aesthetics. Its ARGB functionality allows for customization of lighting effects, adding a personal touch to any build.

In contrast, the Thermalright Peerless Assassin has a more utilitarian design, focusing on performance and functionality. While it may lack the flashy lighting options, its robust construction with aluminum fins and copper heat pipes ensures durability and effective heat dissipation. Users who prefer a clean, professional look may appreciate the simplicity of the Peerless Assassin.

Installation and Compatibility

Both coolers offer ease of installation, with the Delta A40 providing all-metal mounting hardware for compatibility with various Intel and AMD platforms. It supports Intel sockets 115X, 1200, 1700, and 1851, as well as AMD's AM4 and AM5.

Similarly, the Thermalright Peerless Assassin is designed for straightforward installation, also supporting a wide range of Intel and AMD sockets, including LGA 1851, 1700, 1200, 115X, and AM4/AM5. The inclusion of metal fasteners enhances its compatibility and ease of assembly. Both products cater well to DIY builders, but the Delta A40 may have a slight edge for those who prioritize aesthetics during installation.

Noise Levels

Both the Delta A40 and the Thermalright Peerless Assassin operate at impressively low noise levels. The Delta A40 maintains a noise level of ≤29 dB(A), while the Peerless Assassin is rated at ≤29.5 dB(A). This means that users can expect a quiet operation from either cooler, making both suitable for environments where sound levels are a concern, such as home offices or gaming setups.

However, considering the increased performance metrics of the Peerless Assassin, it achieves its cooling efficiency with only a slight increase in noise, which is a worthwhile trade-off for users requiring better thermal management.

Price Consideration

The price difference between the two coolers is significant, with the Delta A40 retailing at C$19.29 and the Thermalright Peerless Assassin at C$54.90. While the Delta A40 is a budget-friendly option, it sacrifices some cooling performance and TDP capacity compared to its more expensive counterpart.

For users with basic cooling needs or those building budget systems, the Delta A40 presents a solid choice. However, for enthusiasts or users requiring enhanced cooling capabilities, the investment in the Thermalright Peerless Assassin could yield better long-term benefits and performance.

Which should you buy?

Choosing between the Delta A40 ARGB CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler depends largely on your cooling needs and budget. If you're looking for a cost-effective solution with decent performance and customizable aesthetics, the Delta A40 is a compelling choice at C$19.29.

However, if you require superior cooling performance for high-powered CPUs, especially for gaming or overclocking, the Thermalright Peerless Assassin at C$54.90 offers significantly better thermal handling and airflow. Ultimately, your choice should be guided by your specific requirements and willingness to invest in better cooling performance.
