Overview
The Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright PS120SE ARGB CPU Air Cooler present two compelling options for PC enthusiasts looking to enhance their cooling solutions. Priced at C$54.90 and C$63.68 respectively, both coolers are designed to provide effective thermal management, but they cater to slightly different needs and preferences.
Design and Build Quality
The Thermalright Peerless Assassin 140 Black boasts a twin-tower design with a height of 158mm, making it a substantial presence in any PC build. Its pure copper six heatpipes enhance heat dissipation through its large aluminium fins. The PS120SE ARGB, on the other hand, features a compact size of 125mm x 135mm x 154mm, which allows it to fit comfortably in a variety of chassis. While both coolers use quality aluminium, the PS120SE also incorporates an anodized black frosted top and a finely carved pure copper base, enhancing its aesthetics and thermal performance.
Cooling Performance
In terms of cooling capabilities, the Peerless Assassin 140 Black is equipped with dual PWM fans that operate at 1500 RPM, generating an air volume of 66.17 CFM while maintaining a noise level below 25.6 dB(A). This cooling efficiency is bolstered by its dual tower configuration, which maximizes the surface area for heat dissipation. Conversely, the PS120SE also features dual PWM fans with the same RPM and air volume specifications, but its unique AGHP technology and S-FDB bearings promise an extended lifespan of up to 20,000 hours, making it a robust choice for long-term use.
Compatibility
Both coolers offer broad compatibility with various CPU sockets. The Peerless Assassin 140 Black supports Intel sockets LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and LGA1851, as well as AMD AM4 and AM5. The PS120SE matches this compatibility, covering Intel LGA1700, LGA1851, LGA1150, LGA1151, LGA1155, LGA1156, and LGA1200, along with AMD’s AM4 and AM5 sockets. This extensive compatibility ensures that both options can be used in a wide variety of builds, catering to different user needs.
Aesthetic Appeal
The aesthetic design varies significantly between the two models. The Peerless Assassin 140 Black has a more traditional, utilitarian look that focuses on function over form. On the other hand, the PS120SE ARGB brings a modern flair with its RGB lighting capabilities, offering up to 17 lighting modes that can be synchronised with your motherboard. This feature allows users to customise their setups further, making the PS120SE a more appealing choice for those who prioritise visual elements in their builds.
Installation Process
Installation is a critical aspect of any CPU cooler, and both products are designed for ease of use. The Peerless Assassin 140 Black includes all-metal fasteners and a SS2 buckle system for secure installation across various CPU models. It also comes with a Y-type adapter cable, ensuring that users can connect both fans efficiently. Meanwhile, the PS120SE provides corresponding mounting plates and installation instructions, making it straightforward to set up. While both coolers aim for user-friendly installation, the additional adapter offered by the Peerless Assassin might give it a slight edge in terms of flexibility.
Price Comparison
When it comes to pricing, the Peerless Assassin 140 Black is the more economical option at C$54.90, making it an attractive choice for budget-conscious consumers. In contrast, the PS120SE ARGB is priced at C$63.68, reflecting its additional features like RGB lighting and the advanced AGHP technology. This price difference of C$8.78 may be justified for users who seek enhanced aesthetics and longevity in their cooling solutions, but for those prioritising pure performance, the Peerless Assassin offers excellent value.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 140 Black and the Thermalright PS120SE ARGB ultimately depends on your specific needs and preferences. If you're focused on raw cooling performance and a lower price point, the Peerless Assassin 140 Black is an excellent value with its dual tower design and efficient airflow. However, if you desire a cooler with aesthetic appeal, RGB lighting, and a slightly more advanced cooling technology, the PS120SE ARGB may be worth the extra investment. Both coolers provide solid performance and compatibility, ensuring that whichever you choose, your CPU will remain well-cooled.
