Dimension comparison
Overview of the Products
In this comparison, we will explore two cooling solutions: the ARCTIC P14 Pro PST - 5 Pack and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler. Priced at £27.49 and £28.79 respectively, both products cater to users looking for effective cooling solutions but differ significantly in their intended applications. The ARCTIC P14 is designed primarily as a case fan with high static pressure capabilities, while the Thermalright Peerless Assassin is a dedicated CPU air cooler with RGB lighting features.
Cooling Performance
The ARCTIC P14 Pro PST excels in cooling performance due to its high static pressure feature, which allows it to maintain airflow even against resistance from dense radiators and mesh structures. This fan can reach speeds of up to 3000 rpm through its PWM control, making it highly efficient for various cooling needs. On the other hand, the Thermalright Peerless Assassin boasts a maximum airflow of 66.17 CFM with a fan speed of approximately 1500 rpm. While both products provide effective cooling, the ARCTIC fan offers a more aggressive performance profile suitable for users needing robust airflow in challenging environments.
Noise Levels
When it comes to noise levels, the ARCTIC P14 Pro is designed with a smooth-running fluid dynamic bearing, which minimises operational noise. This makes it an excellent choice for users who prioritise a quiet environment, especially in settings like home offices or gaming rigs. In comparison, the Thermalright Peerless Assassin operates at a noise level of up to 25.6 dB(A). While this is relatively quiet, the ARCTIC fan's design aims for even less noise, particularly at lower speeds, making it potentially preferable for noise-sensitive users.
Build Quality and Design
The ARCTIC P14 Pro features a new fan blade design which enhances both performance and low noise operation. Its precise manufacturing ensures minimal gaps and high precision, contributing to long-lasting performance. In contrast, the Thermalright Peerless Assassin incorporates six heat pipes and a copper base with full electroplating for durability and efficiency. While both products exhibit solid build quality, the ARCTIC fan leans towards quieter operation while the Thermalright cooler emphasises its robust thermal management capabilities.
Ease of Installation
The installation process differs significantly between the two products. The ARCTIC P14 Pro is a fan that can be easily integrated into various cases with a standard 4-pin PWM connection, allowing for straightforward installation. Conversely, the Thermalright Peerless Assassin is designed as a CPU cooler and supports multiple socket types, including Intel and AMD configurations. It comes with necessary mounting components, making it versatile for different setups. However, its installation may require more effort compared to simply adding a fan.
Aesthetic Appeal
Aesthetically, the Thermalright Peerless Assassin shines with its ARGB lighting effects, offering users the ability to customise their build's appearance. This feature is particularly appealing for gamers and PC builders who want their systems to look as good as they perform. In contrast, the ARCTIC P14 Pro focuses more on functionality and performance, lacking any RGB lighting. The choice between the two will depend on whether visual flair or performance is the priority for the user.
Brand Reputation and Support
Both brands, ARCTIC and Thermalright, have established themselves in the cooling market, with ARCTIC known for its reliable fans and Thermalright for its effective CPU coolers. ARCTIC has a reputation for high-performance cooling solutions, while Thermalright has garnered respect for its innovative designs and effective cooling technologies. With over 20 years in the industry, Thermalright’s brand history may appeal to users seeking reliability and support in their cooling solutions.
Which should you buy?
Choosing between the ARCTIC P14 Pro PST and the Thermalright Peerless Assassin ultimately depends on your specific cooling needs. If you are after high airflow and low noise for case cooling, the ARCTIC P14 Pro’s impressive static pressure and quiet operation make it an excellent choice. However, if you require a dedicated CPU cooler with RGB aesthetics and solid thermal performance, the Thermalright Peerless Assassin is the better option. Both products offer great value for their prices, at £27.49 and £28.79 respectively, but their distinct features cater to different users and applications.
