Overview of Thermalright PS120SE and Thermalright Peerless Assassin 120 Digital ARGB

The Thermalright PS120SE CPU Air Cooler is priced at C$44.90, while the Thermalright Peerless Assassin 120 Digital ARGB is available for C$62.90. Both coolers are designed to efficiently dissipate heat from CPUs, but they employ different technologies and designs that cater to varying user needs.

The PS120SE features a single-tower design with a height of 154mm and an effective air flow of 66.17 CFM. It is equipped with a 120mm PWM fan that operates at a maximum speed of 1500 RPM. In contrast, the Peerless Assassin boasts a dual-tower design, which enhances its cooling capabilities. Standing at 162mm, it is slightly taller and uses dual 120mm fans capable of reaching a speed of 1850 RPM, yielding an impressive air flow of 88.89 CFM.

Cooling Efficiency

When it comes to cooling efficiency, the Thermalright Peerless Assassin stands out with its advanced dual-tower configuration. This design allows for a superior heat dissipation capacity, making it well-suited for high-performance CPUs. The combination of its six pure copper heat pipes and dual fans provides efficient cooling under heavy loads.

On the other hand, the PS120SE, while still effective for standard cooling needs, is limited by its single-tower design. It has a maximum cooling capacity suitable for CPUs with a thermal design power (TDP) of 105W to 280W. The lower fan speed of 1500 RPM compared to the Peerless Assassin's 1850 RPM also contributes to its reduced cooling performance, especially during intense gaming or rendering sessions.

Noise Levels

Both coolers operate at a maximum noise level of ≤25.6 dB(A), ensuring that they remain relatively quiet even under load. This is beneficial for users who prioritise a peaceful computing environment.

However, the design differences may influence perceived noise. The dual fans of the Peerless Assassin, while slightly louder at peak RPM, benefit from advanced S-FDB bearings that reduce vibration noise. In practical terms, the PS120SE may produce a more consistent noise level due to its single fan, but users seeking the utmost quietude might prefer the efficient performance of the dual fans in the Peerless Assassin.

Build Quality and Design

The Thermalright PS120SE features an anodized black frosted top and a finely carved pure copper base, showcasing a high-quality finish and solid build. Its height of 154mm allows for compatibility with a wide range of chassis models, making it a flexible choice for many builds.

In contrast, the Peerless Assassin has a more modern look with a digital display board integrated into its magnetic top cover. This design not only enhances its aesthetic appeal but also allows users to monitor CPU temperatures and customize RGB lighting through TRCC software. The dual-tower configuration, complemented by its height of 162mm, ensures compatibility with most mainstream ATX chassis while providing ample space for high-capacity memory and graphics cards.

Installation and Compatibility

Both coolers are designed with user-friendliness in mind. The PS120SE comes with various mounting plates and fasteners that cater to different CPU socket types, including Intel's LGA1700/1851/1150/1151/1155/1156/1200 and AMD's AM4/AM5. This compatibility makes it a versatile choice for a range of systems.

The Peerless Assassin also supports a wide variety of CPU sockets and offers straightforward installation with its dual fans. The design accommodates larger memory modules and graphics cards without obstruction, which is an important consideration for high-performance builds. Users should note that the additional height of the Peerless Assassin might be a factor when considering case compatibility.

Price Consideration

The Thermalright PS120SE is priced at C$44.90, making it a budget-friendly option for users seeking reliable cooling without breaking the bank. It is ideal for gamers or content creators who do not require extreme cooling performance.

In contrast, the Peerless Assassin is priced at C$62.90, reflecting its advanced cooling capabilities and added features such as dual fans and RGB lighting. While it represents a higher initial investment, the enhanced cooling performance may justify the cost for users with high-end CPUs or those who engage in resource-intensive tasks.

User Reviews and Feedback

User feedback for the Thermalright PS120SE highlights its effective cooling performance for its price point, with many users appreciating its compatibility across various systems. It serves well for mid-range builds and general computing tasks.

On the other hand, the Peerless Assassin receives praise for its exceptional cooling efficiency and innovative design. Users often comment on its performance during overclocking scenarios and its aesthetic appeal, particularly with the digital display and RGB features. However, some users note that its larger size may pose challenges in tighter cases.

Which should you buy?

Choosing between the Thermalright PS120SE and the Thermalright Peerless Assassin ultimately depends on your specific needs and budget. If you are looking for a cost-effective solution that provides reliable cooling for mid-range systems, the PS120SE at C$44.90 is a solid choice.

However, if you require superior cooling performance, especially for demanding applications or overclocking, the Peerless Assassin at C$62.90 offers advanced features and better heat dissipation. Its dual-tower design and additional functionalities, such as customizable RGB lighting, make it a worthwhile investment for enthusiasts seeking high performance and aesthetics in their builds.
