Overview of Thermalright Assassin King 120 SE White ARGB CPU Air Cooler
The Thermalright Assassin King 120 SE White ARGB CPU Air Cooler is priced at $19.82, making it an affordable option for users seeking efficient cooling solutions. This cooler features a compact design with dimensions of 120mm x 73mm x 148mm and a weight of 0.64kg. Its standout features include five heat pipes utilizing AGHP III technology, which enhances thermal performance and provides a long service life of up to 20,000 hours. The cooler is also compatible with a range of Intel and AMD sockets, making it versatile for various builds.
Overview of Thermalright PS120SE CPU Air Cooler
The Thermalright PS120SE CPU Air Cooler is priced at $35.90, which is approximately 81% more than its counterpart. It boasts a larger design, measuring 125mm x 135mm x 154mm and weighing 0.9kg. This cooler utilizes seven heat pipes with upgraded AGHP 4.0 technology, capable of handling a thermal design power (TDP) of 105W to 280W, which significantly enhances its cooling capacity. Like the Assassin King, it supports multiple Intel and AMD sockets, providing flexibility for builders.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright PS120SE is designed for higher thermal loads with its capability to manage TDPs from 105W to 280W. This makes it suitable for more demanding processors and overclocking scenarios. Conversely, the Assassin King 120 SE is optimized for general use, supporting a maximum airflow of 66.17 CFM with a noise level of 25.6 dB(A). Both coolers feature effective PWM fans, but the PS120SE's increased heat pipe count suggests superior thermal dissipation capabilities, especially under high-stress conditions.
Design and Aesthetics
The design of the Thermalright Assassin King 120 SE White ARGB is visually appealing with its white and RGB elements, making it an excellent choice for users looking to enhance their system's aesthetics. In contrast, the PS120SE has a more robust and industrial look with its anodized black frosted top and finely carved pure copper base. While both coolers utilize aluminum for the heat sink material, the choice of design may appeal to different users based on their build theme.
Compatibility and Installation
Both coolers offer broad compatibility with Intel and AMD sockets, including LGA1700, 1150, 1151, 1155, 1156, and AM4/AM5. The Assassin King comes with metal fasteners that ensure a straightforward installation process. Similarly, the PS120SE includes corresponding mounting plates for various CPU socket platforms. However, the slightly heavier and larger nature of the PS120SE may require more space within the case, which users should consider when planning their build.
Noise Levels
When it comes to noise levels, both coolers are rated at a maximum of 25.6 dB(A) during operation, which is commendable for air coolers in this range. The Assassin King features a fan speed of 1550 RPM, while the PS120SE's fan operates at 1500 RPM. Despite the similar noise ratings, the overall acoustic performance may vary depending on the system load and airflow dynamics within the case. Users prioritizing a quiet computing experience will find both options appealing.
Price Analysis
The Thermalright Assassin King 120 SE is priced at $19.82, making it a budget-friendly choice for users who want effective cooling without breaking the bank. On the other hand, the PS120SE is available for $35.90, which is about 81% more expensive. While the price difference can be justified by the PS120SE's enhanced cooling capabilities and design, budget-conscious consumers may prefer the more economical option offered by the Assassin King.
Which should you buy?
Choosing between the Thermalright Assassin King 120 SE and the PS120SE depends largely on your specific needs and budget. If you are looking for an affordable, stylish cooler for general use, the Assassin King is an excellent choice at $19.82. However, if you require superior cooling performance for high-end processors or overclocking, the PS120SE, priced at $35.90, offers enhanced capabilities with its additional heat pipes and higher TDP support. Evaluate your cooling needs, aesthetic preferences, and budget to make the best decision for your build.
