Dimension comparison
Overview of the Thermalright Peerless Assassin 120 Mini Black CPU Cooler
The Thermalright Peerless Assassin 120 Mini Black CPU Cooler is priced at $34.39. This model features a compact design that includes 6 heat pipes and utilizes AGHP technology, making it suitable for a range of Intel and AMD CPUs. Its PWM fan operates at a speed of 1500 RPM, providing efficient cooling while maintaining a noise level of ≤ 25.6 dB(A). Additionally, the cooler’s dimensions are 125mm x 110mm x 135mm, which allows for compatibility with various chassis setups.
The cooler's black aesthetic, coupled with its aluminum construction and copper base, ensures not only functionality but also a sleek appearance. With a maximum airflow of 66.87 CFM, it promises effective heat dissipation, especially in smaller builds where space is a constraint.
Overview of the Thermalright PS120SE ARGB CPU Air Cooler
The Thermalright PS120SE ARGB CPU Air Cooler is slightly more expensive at $34.94. This model offers an advanced cooling solution with 7 heat pipes and also features AGHP technology. It operates dual 120mm TL-C12B-S V2 PWM fans at the same speed of 1500 RPM, ensuring efficient airflow while keeping noise levels at a similar maximum of ≤ 25.6 dB(A). The cooler's dimensions are 125mm x 135mm x 154mm, making it taller than its counterpart.
In addition to its cooling capabilities, the PS120SE boasts an attractive ARGB lighting feature, providing aesthetic appeal with customizable lighting effects. The dual fans enhance its cooling performance, making it a strong contender for users who prioritize both style and function in their builds.
Cooling Performance Comparison
When it comes to cooling performance, both coolers utilize AGHP technology, which minimizes the effects of gravity on heat dissipation. The Thermalright Peerless Assassin 120 Mini Black has a maximum airflow of 66.87 CFM, while the PS120SE offers slightly less at 66.17 CFM. Although the airflow difference is marginal, the PS120SE's additional heat pipe may provide improved overall cooling efficiency by distributing heat more evenly across its larger surface area.
Both coolers share a fan speed of 1500 RPM and noise levels of ≤ 25.6 dB(A), indicating that noise should not be a significant concern for either model. However, the extra heat pipe in the PS120SE suggests a potential edge in cooling performance, particularly for users with demanding CPU workloads.
Aesthetic Appeal and Design
Aesthetic design plays a crucial role in modern PC builds, and here the PS120SE stands out with its ARGB lighting capabilities. It features 17 different lighting modes that can be synchronized with motherboard settings, allowing users to customize their builds extensively. In contrast, the Thermalright Peerless Assassin 120 Mini Black has a more understated look with its fully blackened exterior and CNC precision micro-engraved copper base.
While the Peerless Assassin has a sleek and professional appearance, the added visual flair of the PS120SE may appeal to gamers and RGB enthusiasts. Both coolers are constructed from aluminum, but the PS120SE's anodized finish provides a more modern look.
Compatibility Across Platforms
Both coolers are compatible with a wide range of CPU sockets, supporting Intel LGA variants (including 1150, 1151, 1155, 1156, 1200, 1700, and 1851) and AMD AM4/AM5 sockets. This versatility makes them suitable for various builds, from budget options to high-performance systems.
However, the PS120SE has a slightly taller height at 154mm compared to the Peerless Assassin's 135mm, which may affect compatibility with smaller cases. Users with limited space may want to consider the dimensions carefully when choosing between these two options.
Installation and Setup
Installation for both coolers is user-friendly, with each providing the necessary mounting kits and instructions for various CPU socket types. The Thermalright Peerless Assassin 120 Mini Black’s compact size may facilitate easier installation in tighter spaces. However, the PS120SE, even with its additional height, also promises straightforward installation processes due to its well-designed mounting system.
The inclusion of installation instructions for both models suggests that Thermalright prioritizes user experience, reducing potential headaches during setup.
Pricing and Value Proposition
The Thermalright Peerless Assassin 120 Mini Black is priced at $34.39, which makes it approximately 1.6% cheaper than the PS120SE’s $34.94. This small price difference may appeal to budget-conscious users who still want quality cooling performance. However, considering the additional features and slightly superior performance of the PS120SE, the value proposition may lean in its favor for users willing to invest a bit more for enhanced aesthetics and cooling capabilities.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 120 Mini Black and the Thermalright PS120SE ARGB CPU Air Cooler comes down to personal preferences and specific needs. If budget is your primary concern and you prefer a straightforward, compact design, the Peerless Assassin is a solid choice. However, if you desire advanced cooling performance combined with striking aesthetics and customizable lighting, the PS120SE may justify the slightly higher price. Both coolers deliver reliable performance and compatibility, making either a great option for your PC build.
