Overview of the ARCTIC P12 Pro A-RGB and Thermalright Peerless Assassin 120 SE ARGB
The ARCTIC P12 Pro A-RGB is a powerful premium fan offered in a pack of three, while the Thermalright Peerless Assassin 120 SE ARGB is a CPU air cooler designed for efficient thermal management. With prices of £24.99 and £28.79 respectively, both products cater to enthusiasts looking for effective cooling solutions, albeit in different forms. The P12 Pro is primarily a case fan that excels in airflow and noise management, while the Peerless Assassin focuses on CPU cooling performance.
Cooling Performance
In terms of cooling efficiency, the ARCTIC P12 Pro A-RGB boasts high static pressure, making it effective even in challenging environments, such as dense radiators or perforated panels. The fan can reach an impressive speed of up to 3000 rpm, facilitating airflow that penetrates through various obstacles for reliable cooling. Conversely, the Thermalright Peerless Assassin features a dual tower design and utilises six heat pipes for better heat dissipation. With a maximum airflow of 66.17 CFM and a fan speed of around 1500 rpm, it provides substantial cooling for CPU applications. While both products excel in their respective roles, the choice depends on whether you need case ventilation or CPU cooling.
Noise Levels
Noise output is a significant factor for many users, and here the ARCTIC P12 Pro A-RGB shines with its smooth-running fluid dynamic bearing that reduces vibrations, ensuring quiet operation. It operates efficiently, even at low speeds, making it ideal for users who prefer a quieter PC environment. The Thermalright Peerless Assassin has a specified noise level of up to 25.6 dB(A), which is relatively quiet but may not match the silent performance of the ARCTIC fan at lower RPMs. If noise reduction is a priority, the ARCTIC P12 Pro may be the better choice.
Design and Aesthetics
When it comes to design, the ARCTIC P12 Pro A-RGB features a modern aesthetic with A-RGB lighting that enhances the visual appeal of any build, especially when multiple units are used together. The new fan blade design not only contributes to performance but also adds to its stylish appearance. On the other hand, the Thermalright Peerless Assassin also boasts colourful ARGB effects, adding a vibrant touch to your CPU cooler. While both products have attractive lighting, the ARCTIC’s versatility as case fans allows for more extensive visual integration across a build.
Installation and Compatibility
The ARCTIC P12 Pro A-RGB fans come with a 4-pin PWM connection, which allows for easy installation and compatibility with most modern motherboards and fan controllers. The ability to stop completely at less than 5% PWM is an added convenience. In contrast, the Thermalright Peerless Assassin is designed specifically for CPU cooling and supports a range of sockets, including Intel’s 115X, 1200, and 1700, as well as AMD’s AM4 and AM5. The included mounting hardware ensures straightforward installation, making it a user-friendly option for CPU cooling. While both products are easy to install, the choice may hinge on your specific cooling needs—case fans versus CPU cooler.
Brand Reputation
ARCTIC is known for its focus on performance and value in cooling solutions, making the P12 Pro A-RGB a solid choice for users seeking quality fans. The brand has built a reputation for producing products that balance efficiency with noise management. Thermalright, with over 20 years of experience, has a strong standing in the cooling market as well, particularly among gamers and PC builders. Their Peerless Assassin air cooler reflects their commitment to high-performance cooling. Both brands are reputable, but your preference may depend on brand loyalty or specific product reviews.
Price Comparison
The ARCTIC P12 Pro A-RGB is priced at £24.99 for a pack of three, making it an economical choice for those looking to enhance airflow in their systems without breaking the bank. In comparison, the Thermalright Peerless Assassin comes at £28.79, which is slightly higher but reflects its dual-tower design and CPU cooling capabilities. While both products are competitively priced within their categories, the ARCTIC fans offer better value for users needing multiple units for effective case cooling.
Which should you buy?
Deciding between the ARCTIC P12 Pro A-RGB and the Thermalright Peerless Assassin 120 SE ARGB ultimately depends on your cooling requirements. If you are seeking energy-efficient case fans with high static pressure and low noise, the ARCTIC P12 Pro is the ideal choice. However, if your focus is specifically on CPU cooling with robust performance and dual-tower design, the Thermalright Peerless Assassin is worth considering. Each product excels in its domain, and your final decision should align with your specific cooling needs and system configuration.
