Dimension comparison
Overview of the Thermalright PS120SE ARGB and Assassin King 120 SE ARGB
The Thermalright PS120SE ARGB CPU Air Cooler is priced at C$63.68, substantially more than the Thermalright Assassin King 120 SE ARGB, which retails for C$24.59. This price difference indicates a significant disparity in features and specifications, which may influence a buyer's decision based on their cooling needs and budget constraints.
The PS120SE boasts advanced AGHP technology with a 7x6mm heatpipe system, while the Assassin King features a simpler 5x6mm design. Both coolers aim for efficient heat dissipation, supporting various Intel and AMD sockets. However, the PS120SE's higher price reflects its more sophisticated design and additional features, making it essential to consider the specific benefits of each cooler before making a choice.
Performance Capabilities
The Thermalright PS120SE is designed to handle higher thermal loads with a TDP capability that aligns with its advanced heatpipe technology, ensuring effective cooling for high-performance CPUs. With an airflow of 66.17 CFM and a maximum fan speed of 1500 RPM, it operates at a noise level of just 25.6 dB(A), balancing performance and quiet operation.
In contrast, the Assassin King 120 SE also achieves an airflow of 66.17 CFM but has a slightly higher fan speed at 1550 RPM, maintaining the same noise level of 25.6 dB(A). This means that while both products offer similar cooling performance, the Assassin King may edge out slightly in terms of fan speed, which can be crucial for users who need that extra cooling performance at a lower price point.
Build Quality and Materials
The build quality of the Thermalright PS120SE showcases a combination of high-quality materials, including aluminum for the heat sink and a finely crafted pure copper base. It also features S-FDB bearings for longevity, expected to last up to 20,000 hours. This construction not only enhances the cooler's durability but also its thermal performance.
On the other hand, the Assassin King 120 SE utilises a similar aluminum construction but with a focus on cost efficiency, employing metal fasteners and standard materials. While it also offers a long service life with S-FDB bearings, the overall material quality may not match that of the PS120SE. Hence, users seeking robust build quality might lean towards the PS120SE despite the higher price.
Design and Aesthetics
The PS120SE ARGB cooler features high-brightness LED lighting, offering a total of 17 lighting modes that can be synchronised with a motherboard for a cohesive aesthetic. This is particularly appealing for users who prioritise visual elements in their PC builds.
Conversely, the Assassin King 120 SE also includes colourful ARGB effects but does not specify the number of modes available. While both coolers provide attractive lighting options, the PS120SE's more extensive customisation possibilities may be a significant draw for enthusiasts focused on aesthetics, especially in a showcase build.
Dimensions and Compatibility
In terms of size, the PS120SE measures 125mm (L) x 135mm (W) x 154mm (H), making it compatible with a wide range of chassis. It supports various CPU sockets, including Intel's LGA1700/1851/1150/1151/1155/1156/1200 and AMD's AM4/AM5. This broad compatibility ensures that users can install it in various builds without concern.
The Assassin King 120 SE is slightly smaller at 120mm (L) x 73mm (W) x 148mm (H), which may make it a better fit for compact cases. It also supports a good range of sockets, including Intel's 115X/1200/1700/17XX and AMD's AM4/AM5. While both coolers are versatile, the PS120SE's broader compatibility may appeal to those with more extensive setups.
Noise Levels
Both the Thermalright PS120SE and Assassin King 120 SE operate at a maximum noise level of 25.6 dB(A), making them both excellent choices for users who value a quiet computing experience. This low noise level is achievable due to the efficient design and quality of the S-FDB bearings used in both models.
However, considering the fan speeds, the Assassin King operates at a slightly higher RPM, which could theoretically lead to increased noise in certain situations. Nevertheless, both coolers are designed to maintain a quiet environment, making them suitable for gaming or office use without annoying distractions.
Market Position and Value
At C$63.68, the Thermalright PS120SE ARGB is positioned as a premium cooler, reflecting its advanced features and superior build quality. Buyers investing in this cooler can expect enhanced performance suitable for high-demand applications or overclocking scenarios.
In contrast, the Assassin King 120 SE offers excellent value at C$24.59, making it an attractive option for budget-conscious consumers or those looking for reliable cooling without the frills. While it may not match the PS120SE in terms of advanced features, it still delivers solid performance for everyday use.
Which should you buy?
Deciding between the Thermalright PS120SE ARGB and the Assassin King 120 SE ARGB ultimately depends on your specific needs and budget. If you require advanced cooling capabilities, superior build quality, and aesthetic flexibility, the PS120SE is worth the investment at C$63.68. However, if you're looking for a reliable, well-performing cooler at an affordable price, the Assassin King at C$24.59 provides excellent value without compromising on essential features.
