ARCTIC P12 Slim PWM PST vs Thermalright Assassin X120 SE ARGB CPU Air Cooler

Overview

In this comparison, we will examine the ARCTIC P12 Slim PWM PST and the Thermalright Assassin X120 SE ARGB CPU Air Cooler. Both products cater to cooling needs but target different use cases and configurations. The ARCTIC P12 Slim PWM PST is priced at £18.90, while the Thermalright Assassin X120 SE is slightly cheaper at £16.29. This price differential hints at varying performance and functionality.

Design and Build Quality

The design and build quality of cooling products significantly impact their performance. The ARCTIC P12 Slim PWM PST boasts a low installation height of just 15 mm, making it an excellent choice for compact builds where space is a premium. In contrast, the Thermalright Assassin X120 SE has a larger footprint with dimensions of 120 mm x 71 mm x 148 mm, weighing 0.63 kg. While the Assassin X120 SE is designed for larger cases, it features an eye-catching ARGB lighting system that enhances aesthetics, appealing to gamers and PC builders who prioritise visual flair alongside functionality.

Cooling Performance

Cooling performance is paramount for any CPU cooler. The ARCTIC P12 Slim PWM PST operates with a fan speed ranging from 200 to 2100 RPM, delivering strong static pressure of 1.33 mmH₂O, which is particularly effective in overcoming air resistance. This fan can achieve an airflow of 34.51 CFM, making it suitable for high-performance cooling applications. On the other hand, the Thermalright Assassin X120 SE features a maximum airflow of 66.17 CFM from its standard 120 mm fan, operating at a maximum speed of 1550 RPM. This indicates that while the P12 Slim excels in static pressure, the Assassin X120 SE provides superior airflow, making it a robust choice for larger setups.

Noise Level

When considering cooling solutions, noise levels are crucial for creating a pleasant computing environment. The ARCTIC P12 Slim PWM PST operates at a low noise level of just 0.3 Sone, ensuring a quiet operation even under load. In contrast, the Thermalright Assassin X120 SE has a noise level of up to 25.6 dB(A). While this is relatively quiet, it may be noticeable in quiet environments, especially when compared directly to the near-silent operation of the P12 Slim. Therefore, if a whisper-quiet operation is a priority, the ARCTIC fan has a clear advantage.

Compatibility and Installation

Compatibility and ease of installation are significant factors for users. The ARCTIC P12 Slim PWM PST is designed with a 4-pin connector for PWM control and is highly versatile, making it suitable for various applications, including heat sinks and radiators. Conversely, the Thermalright Assassin X120 SE supports multiple CPU socket platforms, including both Intel and AMD, with mounting hardware provided for a straightforward installation. Its comprehensive compatibility makes it an attractive option for users with different CPU configurations, while the P12 Slim’s slim profile allows it to fit into tight spaces.

Longevity and Reliability

Longevity and reliability are essential for any cooling solution. The ARCTIC P12 Slim PWM PST benefits from improved engine technology and a newly developed fan design, which contributes to its overall performance and durability. While specific lifespan data for the P12 Slim is not provided, the Thermalright Assassin X120 SE employs S-FDB bearings and promises an operational life of up to 20,000 hours. This longevity suggests that the Assassin X120 SE may offer better durability under continuous use, making it a reliable choice for users who run their systems for extended periods.

Aesthetics

Aesthetics play a considerable role in modern PC builds, especially for gamers. The ARCTIC P12 Slim PWM PST focuses on performance and practicality, lacking any RGB features. In contrast, the Thermalright Assassin X120 SE is equipped with colourful ARGB lighting effects, allowing builders to customise their systems' look. This feature can enhance the overall visual appeal of a rig, making the Assassin X120 SE an attractive choice for those who value aesthetics as much as performance.

Price-to-Performance Ratio

When evaluating price-to-performance ratios, the ARCTIC P12 Slim PWM PST is priced at £18.90, while the Thermalright Assassin X120 SE comes in at £16.29. Despite its lower price, the Assassin X120 SE offers superior airflow capabilities and attractive aesthetics, which can justify its cost for users seeking a balance of performance and style. However, for those prioritising noise levels and compact design, the ARCTIC P12 Slim could be seen as offering better value for smaller builds.

Which should you buy?

Ultimately, the decision between the ARCTIC P12 Slim PWM PST and the Thermalright Assassin X120 SE depends on your specific needs. Choose the ARCTIC P12 Slim if you require a compact, quiet solution with solid static pressure for high-performance cooling in tight spaces. On the other hand, if you want a more visually appealing cooler with higher airflow capabilities for larger cases and are willing to accept a slightly noisier operation, the Thermalright Assassin X120 SE is the better option. Each cooler has its strengths, so your choice will hinge on your unique use case and preferences.
