Price Comparison
The ARCTIC P12 Pro Reverse A-RGB is priced at $28.99, while the Thermalright Assassin X 120R SE V2 CPU Cooler comes in at a considerably lower price of $16.59. This makes the Thermalright option about 43% cheaper than the ARCTIC fan. If budget is a primary concern for your build, the Thermalright model stands out as a more economical choice without sacrificing essential features.
Cooling Performance
In terms of cooling capability, the ARCTIC P12 Pro Reverse A-RGB boasts a wide speed range, operating between 500 to 3000 RPM. This impressive range allows for dynamic adjustment based on cooling needs, making it versatile for various setups. On the other hand, the Thermalright Assassin X 120R SE V2 features a fan speed of 1550 RPM. While it operates at a lower maximum speed, its design incorporates four heat pipes and a copper base, which enhances its thermal conductivity. Both products are engineered for effective cooling, but the ARCTIC offers a broader speed range that can cater to more demanding cooling scenarios.
Design and Aesthetics
The ARCTIC P12 Pro Reverse A-RGB stands out with its reversed airflow design, specifically optimized for glass-fronted designs. This makes it ideal for builds where aesthetics are key, as it minimizes visible fan blades. The inclusion of 5V Digital RGB lighting adds a visual flair, enhancing the overall look of the build. In contrast, the Thermalright Assassin X 120R SE V2 also features RGB lighting but focuses more on performance and compatibility than on aesthetics. While both products have their visual appeal, the ARCTIC's design is particularly suited for users who prioritize appearance alongside functionality.
Noise Levels
Regarding noise levels, the ARCTIC P12 Pro Reverse A-RGB is designed to minimize vibrations with its hydrodynamic bearing, ensuring quiet operation even at higher speeds. Although the exact dB levels are not specified, its design suggests that noise will be kept to a minimum. Conversely, the Thermalright Assassin X 120R SE V2's fan operates with a noise level of up to 25.6 dB, which is relatively quiet for a CPU cooler. While both products aim for silent operation, the ARCTIC's advanced bearing technology could provide an edge in noise reduction, especially when under load.
Installation and Compatibility
The ARCTIC P12 Pro Reverse A-RGB features a straightforward installation process, thanks to its 4-pin PWM connection and Y cable splitter, which simplifies connecting multiple fans. The Thermalright Assassin X 120R SE V2 also offers a user-friendly installation experience, equipped with metal fasteners for both Intel and AMD platforms. It supports a variety of CPU sockets, making it flexible for different builds. While both products are designed for easy installation, the Thermalright's compatibility with multiple platforms may appeal to users with diverse hardware.
Longevity and Durability
Durability is a crucial factor in cooling solutions, and both the ARCTIC P12 Pro Reverse A-RGB and the Thermalright Assassin X 120R SE V2 are engineered for longevity. The ARCTIC fan features a self-lubricating bearing that minimizes wear and tear, which is essential for long-term use. Meanwhile, the Thermalright cooler employs S-FDB bearings designed to reduce noise and enhance the lifespan of the fan. Both products focus on delivering durable performance, but the ARCTIC's advanced bearing system may provide a slight advantage in terms of operational longevity.
User Experience and Performance
When it comes to user experience, the ARCTIC P12 Pro Reverse A-RGB is tailored for high-performance needs, making it suitable for gamers and heavy users who demand optimal cooling efficiency. Its ability to adjust speeds dynamically means users can fine-tune performance as needed. The Thermalright Assassin X 120R SE V2, while slightly less powerful in terms of maximum RPM, offers reliable cooling with a quieter operation, making it a solid choice for those who prioritize a balance between performance and noise. Each product caters to different user preferences, whether you're after extreme performance or quieter operation.
Which should you buy?
Ultimately, your choice between the ARCTIC P12 Pro Reverse A-RGB and the Thermalright Assassin X 120R SE V2 will depend on your specific needs and budget. If you are looking for a high-performance cooling solution with advanced features and aesthetics, the ARCTIC fan is a solid investment at $28.99. However, if you prioritize cost-effectiveness and still want a reliable cooler, the Thermalright option at $16.59 certainly delivers value. Consider your cooling requirements, noise tolerance, and budget to make the best decision for your build.
