Overview of the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler

The Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler is priced at $45.90, making it a premium choice in the CPU cooling market. This cooler features a dual tower design and is equipped with six heat pipes, which are designed to provide effective heat dissipation. The cooler's standout feature is its digital screen top cover, which not only adds aesthetic value but also enhances functionality. The Peerless Assassin is compatible with a wide range of CPU sockets, including AMD AM4/AM5 and Intel LGA1700/1851/1150/1151/1200, ensuring it can fit into various builds.

Overview of the Thermalright PS120SE ARGB CPU Air Cooler

On the other hand, the Thermalright PS120SE ARGB CPU Air Cooler is available for $34.94, making it about 17% cheaper than its competitor. This model boasts seven heat pipes and dual 120mm fans, providing robust cooling performance. The PS120SE also features the latest AGHP 4.0 technology, which helps mitigate the inverse gravity effect experienced in vertical or horizontal orientations. Like the Peerless Assassin, it supports a variety of CPU sockets, including AMD AM4/AM5 and Intel LGA1700/1150/1151/1200, making it versatile for different setups.

Cooling Performance Comparison

In terms of cooling performance, the Peerless Assassin is designed with six heat pipes and dual fans operating at a maximum speed of 1850 RPM, delivering an airflow of 88.89 CFM. This setup allows for effective heat dissipation, which is crucial for high-performance CPUs. Conversely, the PS120SE, with its seven heat pipes and dual 120mm fans running at a maximum speed of 1500 RPM, offers an airflow of 66.17 CFM. While it has one more heat pipe, the lower fan speed results in a slightly less effective cooling performance compared to the Peerless Assassin.

Noise Levels and Fan Efficiency

The noise levels for both coolers are rated at ≤25.6 dB(A), ensuring a quiet operation during use. However, the Peerless Assassin's fans, with their higher RPM, may produce a more pronounced noise under load compared to the PS120SE's slower fans. The PS120SE employs S-FDB bearings, which are known for their longevity and quiet performance. Therefore, while the cooling efficiency of the Peerless Assassin might edge out, the PS120SE offers a quieter experience, appealing to users prioritizing low noise levels.

Design and Aesthetics

Design-wise, the Peerless Assassin features a sleek black finish with a digital top cover that enhances its visual appeal. This cooler is 162mm in height, making it slightly taller than the PS120SE, which stands at 154mm. The digital display adds a modern touch and can display various information, enhancing the user experience. Meanwhile, the PS120SE also showcases an eye-catching ARGB lighting system that can be synchronized with a motherboard and includes up to 17 lighting modes. Both models have aesthetic features that cater to gamers and PC enthusiasts who appreciate customizable lighting.

Installation and Compatibility

Both coolers are designed for easy installation and compatibility with a variety of platforms. The Peerless Assassin comes with dual-platform mounting clips, ensuring it can be installed on either AMD or Intel sockets without hassle. Similarly, the PS120SE also provides the necessary mounting plates and instructions for a straightforward setup. The slight height difference between the two models may affect compatibility in tightly packed cases, but both should fit within standard ATX chassis.

Price and Value Proposition

The Thermalright Peerless Assassin is priced at $45.90, while the PS120SE is more budget-friendly at $34.94. This price difference of approximately $10.96 reflects the additional features and slightly better cooling performance offered by the Peerless Assassin. However, the PS120SE still presents a compelling value proposition with its effective cooling and ARGB features at a lower price point. For users on a tighter budget, the PS120SE is an attractive option without sacrificing essential performance.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler and the Thermalright PS120SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you prioritize superior cooling performance and a unique digital display, the Peerless Assassin is worth the extra cost. On the other hand, if you’re looking for a more economical choice that still delivers effective cooling and stylish ARGB lighting, the PS120SE is an excellent alternative. Both coolers cater to a diverse range of CPU setups, ensuring compatibility and performance for any build.
