Overview of Thermalright Peerless Assassin 120 Black
The Thermalright Peerless Assassin 120 Black is a formidable CPU air cooler designed for optimal thermal performance. Priced at $38.90, it features six heat pipes and dual PWM fans that enhance cooling efficiency, making it suitable for a wide range of Intel and AMD processors. Its design incorporates advanced AGHP technology, which helps mitigate the inverse gravity effect, ensuring consistent cooling performance regardless of orientation.
With dimensions of 125(L)x135(W)x157(H) mm, this cooler has a substantial footprint that contributes to its effective heat dissipation area of 9600 cm². The use of aluminum in its construction not only aids in weight management—at 1.02 kg—but also enhances durability, providing a robust option for gamers and professionals alike.
Overview of Thermalright PS120SE ARGB
The Thermalright PS120SE ARGB is another strong contender in the CPU cooler market, retailing at a slightly lower price of $34.94. It features seven heat pipes and dual PWM fans, which also provide effective cooling performance. This model is particularly enhanced by its ARGB lighting, which can create an aesthetically pleasing setup for users who prioritize visuals alongside functionality.
Measuring 125(L)x135(W)x154(H) mm, it has a height of 154 mm, making it compatible with a wide range of chassis models. The PS120SE ARGB utilizes advanced AGHP 4.0 technology, ensuring a reliable cooling solution with a longer service life of up to 20,000 hours. With these features, it appeals to gamers and PC builders seeking both performance and style.
Cooling Performance Comparison
In terms of cooling performance, both the Thermalright Peerless Assassin 120 Black and the PS120SE ARGB are engineered for effective heat dissipation. The Peerless Assassin offers a TDP of 245W, which showcases its ability to handle high-performance CPUs. Its dual TL-C12B PWM fans have a maximum airflow of 66.17 CFM and operate at a noise level of ≤25.6 dB(A), ensuring quiet operation while maintaining efficient cooling.
On the other hand, the PS120SE ARGB, with its seven heat pipes, boasts similar airflow capabilities with the same 66.17 CFM and noise level specifications. However, the added heat pipe may provide a slight edge in thermal management, potentially making it better suited for overclocking scenarios or systems with high thermal outputs.
Design and Aesthetics
The design of both coolers reflects Thermalright's commitment to functionality and aesthetics. The Peerless Assassin features a sleek black aluminum heatsink cover, which provides a modern look while ensuring effective heat dissipation. Its dual tower configuration is designed for optimal airflow and performance, fitting seamlessly into various builds.
Conversely, the PS120SE ARGB incorporates RGB lighting, enhancing its visual appeal for users who seek a customizable aesthetic. The cooler's anodized black frosted top, combined with its finely carved pure copper base, not only looks great but also maximizes thermal conductivity. With up to 17 lighting modes available, users can synchronize the cooler’s lighting with their other components for a cohesive look.
Compatibility and Installation
Both coolers boast impressive compatibility with a range of CPU sockets. The Thermalright Peerless Assassin supports Intel sockets including LGA 1150, 1151, 1155, 1156, 1200, 1700, and 2066, as well as AMD AM4 and AM5. The PS120SE ARGB matches this compatibility, supporting similar Intel and AMD sockets, ensuring that users can easily install either cooler on most modern processors.
Installation is streamlined for both models, with included mounting plates and fasteners designed to facilitate a hassle-free setup. However, the Peerless Assassin's slightly larger height may require additional consideration for case clearance in some builds, while the PS120SE ARGB's height of 154 mm is broadly compatible with most chassis.
Noise Levels and Operation
Noise levels are a critical factor for many PC builders, particularly those who desire a quiet working environment. Both the Thermalright Peerless Assassin 120 Black and the PS120SE ARGB operate at a maximum noise level of ≤25.6 dB(A), making them relatively silent during operation. This is particularly beneficial for users who engage in gaming or video editing, where a calm environment is preferred.
With both coolers employing PWM fans, users can expect efficient and responsive cooling that adapts to the CPU's thermal load, further minimizing noise output during lighter tasks. This shared characteristic ensures that both units are suitable for users prioritizing a quiet computing experience.
Price Comparison
The Thermalright Peerless Assassin 120 Black is priced at $38.90, while the Thermalright PS120SE ARGB comes at a slightly lower price of $34.94. This makes the PS120SE ARGB about 8% cheaper than its competitor. Given the slight price difference, budget-conscious buyers may lean towards the PS120SE ARGB, especially considering its added aesthetic features with ARGB lighting. However, the Peerless Assassin offers a slightly higher TDP rating, which may justify its price for users needing maximum cooling performance.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Black and the PS120SE ARGB ultimately depends on individual preferences and specific use cases. If cooling performance is your primary concern, the Peerless Assassin—with its higher TDP and dual tower design—might be the better choice. However, if you value aesthetics and a slightly lower price point, the PS120SE ARGB provides excellent cooling with the added benefit of customizable RGB lighting. Both coolers are excellent options, but your decision should align with your specific needs, whether that’s performance, aesthetics, or budget.
