Overview of Thermalright Peerless Assassin 120 Digital ARGB Black
The Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler is a premium offering priced at C$52.62. This cooler incorporates an advanced dual-tower design with dual fans that can reach a speed of 1850 RPM, providing a substantial airflow of 88.89 CFM. Additionally, it features ARGB lighting, allowing for customizable aesthetics via motherboard software. With an operating noise of 25.6 dBA, this model is designed for users who prioritise both performance and visual appeal.
Performance Comparison
In terms of performance, the Peerless Assassin 120 outperforms the TL-S12W X3 with its higher fan speed of 1850 RPM compared to the TL-S12W X3’s 1500 RPM. The increased speed allows the Peerless Assassin 120 to achieve an airflow of 88.89 CFM, significantly higher than the TL-S12W X3’s 47.6 CFM. This difference in airflow can result in more effective heat dissipation, making the Peerless Assassin 120 a better choice for high-performance CPUs that generate substantial heat during operation.
Noise Levels
Noise is a crucial consideration in cooling solutions, especially for users who seek a quieter computing environment. The TL-S12W X3 operates at a maximum noise level of 23.2 dBA, which is quieter than the Peerless Assassin 120’s 25.6 dBA. For those who prioritise silence, the TL-S12W X3 might be more appealing. However, the slight increase in noise of the Peerless Assassin is often deemed acceptable given its superior cooling capabilities, especially during high-load situations.
Installation and Compatibility
Both products boast user-friendly installation processes, but they cater to slightly different needs. The TL-S12W X3 comes as a pack of three fans, including 12 mounting screws, making it suitable for users looking to enhance airflow in multiple areas of their PC case. In contrast, the Peerless Assassin 120 includes dual fans and is specifically designed as a CPU cooler, with compatibility across various platforms including AMD and Intel sockets. The installation clips provided with the Peerless Assassin facilitate easy mounting on different CPU types, making it versatile for a range of builds.
Aesthetics and Design
The aesthetic appeal of a cooling solution can enhance the overall look of a PC build. The Peerless Assassin 120 features ARGB lighting that can be synchronised with motherboard software, allowing users to customise the lighting effects according to their preferences. This visual element is absent in the TL-S12W X3, which focuses on functionality over style. For users who value aesthetics alongside performance, the Peerless Assassin 120 presents a significant advantage.
Price Consideration
Price is a decisive factor when choosing between these two products. The TL-S12W X3 is notably more affordable at C$19.59 for three fans, whereas the Peerless Assassin 120 is priced at C$52.62 for a dual-fan cooler. While the TL-S12W X3 provides excellent value for those needing basic cooling, the higher-priced Peerless Assassin 120 offers advanced features and superior performance that may justify its cost for enthusiasts and gamers who require optimal thermal management.
Which should you buy?
Choosing between the Thermalright TL-S12W X3 and the Thermalright Peerless Assassin 120 Digital ARGB Black ultimately depends on your specific needs and priorities. If you are looking for an economical solution that provides adequate cooling and operates quietly, the TL-S12W X3 is a great choice. However, if you require superior cooling performance and appreciate customizable aesthetics, the Peerless Assassin 120 is worth the higher investment. Each product has its strengths, making the decision largely dependent on your cooling requirements and budget.
