Price Comparison
The ARCTIC P12 Pro A-RGB fan is priced at $12.49, while the Thermalright Assassin X120 Refined SE CPU Air Cooler costs $17.90. This makes the ARCTIC fan about 30% cheaper than the Thermalright cooler. For budget-conscious consumers, the significant price difference may be a key factor in their decision-making process. While the ARCTIC fan offers an economical choice, the Thermalright cooler could justify its higher price with additional features and performance benefits.
Performance and Cooling Efficiency
When it comes to cooling efficiency, the ARCTIC P12 Pro A-RGB fan boasts a speed range of 600 to 3000 RPM, allowing for high static pressure even in challenging environments like dense radiators. This capability ensures reliable cooling under various conditions. On the other hand, the Thermalright Assassin X120 Refined SE features a PWM fan with a maximum speed of 1550 RPM and an airflow of 66.17 CFM. While the Thermalright cooler operates at a lower maximum speed, its design includes four heat pipes that enhance its heat dissipation capabilities. Depending on your cooling needs, either product could excel in different scenarios.
Noise Levels
The ARCTIC fan is designed for quiet operation, with its fluid dynamic bearing minimizing noise during use. While specific decibel ratings for the ARCTIC fan are not provided, the emphasis on quiet performance suggests it is suitable for noise-sensitive environments. In contrast, the Thermalright Assassin X120 claims a noise level of ≤25.6 dB(A). Although the Thermalright cooler may produce a higher noise level than the ARCTIC fan, it still promises an efficient cooling solution with a focus on low noise, making both options viable for users who prioritize quiet performance.
Build Quality and Durability
The ARCTIC P12 Pro A-RGB fan features a smooth-running fluid dynamic bearing, which is designed to provide a long service life and reliable performance. The precise manufacturing process reduces vibrations, enhancing durability. On the other hand, the Thermalright Assassin X120 is built with an aluminum heatsink cover and utilizes AGHP technology for enhanced heat transfer efficiency. The cooler’s S-FDB bearings ensure a long lifespan, rated for up to 20,000 hours of industrial service life. Both products offer solid build quality, but the use of aluminum in the Thermalright cooler may add to its durability in high-performance scenarios.
Aesthetic Appeal
In terms of aesthetics, the ARCTIC P12 Pro A-RGB fan features 5V digital RGB lighting, allowing for customizable lighting effects that can enhance the visual appeal of a gaming rig or workstation. The sleek black design also adds a modern touch. Conversely, the Thermalright Assassin X120 does not mention any RGB features, focusing instead on its functional design. For users who prioritize aesthetics alongside performance, the ARCTIC fan may be the preferable choice due to its lighting capabilities.
Compatibility
The ARCTIC P12 Pro A-RGB fan is a versatile option that can be used in various cooling setups, thanks to its 4-pin PWM connection and compatibility with different radiators and cases. Meanwhile, the Thermalright Assassin X120 supports a wide range of CPU sockets, including AMD AM4/AM5 and Intel LGA 1150/1151/1155/1200/1700/1851, making it a highly compatible choice for users with diverse system configurations. If you’re looking for a fan that fits into any setup, the ARCTIC fan excels, while the Thermalright cooler is ideal for those needing a robust air cooling solution compatible with many CPU types.
Installation Process
The ARCTIC P12 Pro A-RGB fan can be easily installed due to its standard size and PWM connection. It is designed for straightforward integration into existing cooling systems. In comparison, the Thermalright Assassin X120 includes metal fasteners specifically designed for both Intel and AMD platforms, ensuring a secure and easy installation process. The thoughtful design of both products contributes to a user-friendly experience, although the Thermalright cooler may require more attention during installation due to its additional components.
Which should you buy?
Ultimately, the choice between the ARCTIC P12 Pro A-RGB fan and the Thermalright Assassin X120 Refined SE CPU Air Cooler comes down to specific needs and preferences. If you are looking for a cost-effective cooling solution with customizable RGB lighting and high RPM capability, the ARCTIC fan is the way to go. However, if you need a more robust CPU cooling solution with proven heat dissipation features and extensive compatibility, the Thermalright cooler may be worth the extra investment. Consider what aspects are most important to your build to make the best choice.
