Dimension comparison
Brand Overview
Both the Thermalright Peerless Assassin 120 SE ARGB and the Thermalright PS120SE are products from Thermalright, a reputable Taiwanese brand with over 20 years of experience in computer accessories. The Peerless Assassin is priced at C$46.90, while the PS120SE is slightly more affordable at C$44.90. Thermalright has established itself as a key player in the cooling market, focusing on innovative designs and high-performance cooling solutions.
Design and Build Quality
The Thermalright Peerless Assassin 120 SE ARGB features a robust design with dimensions of 125(L)x135(W)x155(H)mm, weighing in at 0.97kg. In contrast, the PS120SE maintains similar dimensions of 125(L)x135(W)x154(H)mm but is marginally lighter at 0.9kg. Both coolers utilise aluminum for their heat sinks, but the PS120SE stands out with its anodized black frosted top and finely carved pure copper base, enhancing its aesthetic appeal and thermal performance.
Cooling Performance
When it comes to cooling capabilities, the Peerless Assassin boasts a thermal design power (TDP) range of 120 to 245W, facilitated by its advanced AGHP technique featuring 6×6mm heat pipes. The PS120SE, on the other hand, has a wider TDP range of 105 to 280W thanks to its upgraded 4th generation AGHP technology with 7×6mm heat pipes. This makes the PS120SE potentially more versatile in handling a broader range of CPU loads.
Fan Specifications
Both coolers are equipped with 120mm PWM fans that operate at a maximum speed of 1500 RPM, generating an airflow of 66.17 CFM. However, the Peerless Assassin's fans are specifically designed to operate at a noise level of ≤25.6dB(A), matching the PS120SE in this respect. This means that both products promise quiet operation without sacrificing airflow, making them suitable for various builds, including those prioritising silent performance.
Compatibility
Compatibility is a crucial factor for CPU coolers, and both models excel in this area. The Peerless Assassin supports Intel sockets 115X/1200/1700/17XX and AMD AM4, while the PS120SE accommodates a broader range of Intel sockets, including LGA1700/1851/1150/1151/1155/1156/1200, as well as AMD AM4/AM5. This wider compatibility of the PS120SE might appeal to users with the latest CPU models, ensuring that it can cater to a variety of system builds.
Installation and Ease of Use
Installation ease is essential for any air cooler, and both the Peerless Assassin and PS120SE come with metal fasteners for secure attachment to both Intel and AMD platforms. The Peerless Assassin features a thoughtful design that leaves ample room for memory clearance, simplifying the installation process. Similarly, the PS120SE is designed to avoid interference with memory placement, ensuring that users can set it up without hassle, regardless of the specific RAM configuration.
Price and Value
In terms of pricing, the Thermalright Peerless Assassin 120 SE ARGB is available for C$46.90, while the Thermalright PS120SE is priced at C$44.90. The slight price difference reflects the additional features and aesthetic appeal of the Peerless Assassin, which includes ARGB lighting. However, considering the performance metrics, the PS120SE offers excellent value for a slightly lower price point, making it an enticing option for budget-conscious buyers.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE ARGB and the Thermalright PS120SE ultimately depends on your specific needs and preferences. If you value aesthetic appeal and are looking for a cooler that can handle a substantial TDP within its range, the Peerless Assassin is a solid choice. On the other hand, if you seek a more versatile cooler with broader compatibility and excellent performance at a slightly lower price, the PS120SE stands out as a compelling option. Both products reflect Thermalright's commitment to quality and performance, ensuring that you will be satisfied with either choice.
