Dimension comparison
Brand Overview
The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler is a product from a brand with over 20 years of experience in the cooling market. In contrast, the ARCTIC P14 Slim PWM PST PC Fan comes from ARCTIC, a brand known for its innovative cooling solutions. The credibility of both brands plays a significant role in their respective products, offering customers reassurance in terms of quality and performance. Thermalright has established a strong reputation in the player market, while ARCTIC focuses on high-efficiency cooling through advanced technology.
Design and Build Quality
Thermalright’s Peerless Assassin features a robust design with a double tower cooling system, utilising six heat pipes for optimal thermal dissipation. This design is complemented by the inclusion of two PWM fans, which not only provide cooling but also feature colourful ARGB lighting effects. In contrast, the ARCTIC P14 Slim is designed with a low profile, measuring just 16 mm in height, making it ideal for compact setups. Despite its slim design, it delivers strong cooling performance, indicating a well-thought-out engineering approach in both products.
Cooling Performance
The Thermalright Peerless Assassin boasts a maximum airflow of 66.17 CFM and operates at a fan speed of 1500 RPM. This performance is enhanced by its AGHP technique, which optimises heat transfer and cooling efficiency. On the other hand, the ARCTIC P14 Slim can achieve a fan speed range of 150 to 1800 RPM, with an airflow of 47 CFM. While the P14 Slim is effective in static pressure applications, especially in tight spaces, the Peerless Assassin is better suited for larger systems requiring more substantial cooling capabilities.
Noise Levels
The Thermalright Peerless Assassin operates at a noise level of up to 25.6 dB(A), which is relatively quiet for a CPU cooler of its size and performance. This makes it suitable for builds where noise is a concern. Conversely, the ARCTIC P14 Slim's noise level is measured at 0.3 Sone, which translates to a very quiet operation as well. Both products are designed to minimise noise while maximising performance, catering to users who prioritise a quiet computing environment.
Compatibility
The Thermalright Peerless Assassin is compatible with a range of Intel and AMD sockets, including the latest AM5 and LGA1700, providing versatility for various builds. It comes equipped with necessary mounting hardware, ensuring easy installation across different platforms. In comparison, the ARCTIC P14 Slim is primarily a fan that can fit in both cases and coolers, making it suitable for various applications. However, it does not offer the same level of compatibility as a dedicated CPU cooler, which may limit its usability in certain configurations.
Price Point
At a price of £28.79, the Thermalright Peerless Assassin positions itself as a premium CPU cooler with advanced features and performance capabilities. This investment is justified by its cooling efficiency and aesthetic appeal due to the ARGB lighting. In stark contrast, the ARCTIC P14 Slim is priced at just £6.32, making it an attractive option for budget-conscious consumers looking for a reliable fan solution. While the pricing reflects the differing functionalities of each product, value can be seen in both, depending on the user's needs.
User Experience
User experience with the Thermalright Peerless Assassin is likely to be enhanced by its aesthetic features and robust performance, particularly in gaming and high-performance scenarios. The dual fans contribute to effective cooling while adding a visual flair to any build. The ARCTIC P14 Slim, being a fan, offers a straightforward installation process, especially in compact cases. Its slim profile means it can fit into tight spaces where traditional fans might not, catering to users with space constraints.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler and the ARCTIC P14 Slim PWM PST PC Fan ultimately depends on your specific needs. If you require a powerful CPU cooler with RGB aesthetics and compatibility with various sockets, the Peerless Assassin is the clear choice. However, if you are looking for an affordable fan that performs well in constrained spaces, the ARCTIC P14 Slim is an excellent option. Therefore, weigh your priorities in terms of performance, aesthetics, and budget to make the best decision for your setup.
