Introduction

In this comparison, we will explore two CPU coolers from Thermalright: the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler and the Thermalright PS120SE ARGB CPU Air Cooler. Both models offer unique features aimed at enhancing your cooling experience, but they also differ significantly in design, performance, and price.

Design and Build Quality

The Thermalright Assassin King 120 SE White ARGB features a sleek design with a white aesthetic, making it an attractive option for users looking to enhance the visual appeal of their builds. It is constructed with aluminum and features 5 heat pipes designed with AGHP technology. On the other hand, the Thermalright PS120SE has a slightly larger footprint, measuring 125(L)x135(W)x154(H)mm, compared to the Assassin King’s dimensions of 120(L)x73(W)x148(H)mm. This cooler boasts 7 heat pipes and a more robust aluminum construction, promoting better heat dissipation.

Cooling Performance

When it comes to cooling performance, the PS120SE stands out with its dual 120mm TL-C12B-S V2 PWM fans, which can push air at a speed of 1500 RPM. In contrast, the Assassin King utilizes a single TL-C12CW-S PWM fan with a maximum speed of 1550 RPM. Despite this, both models have a maximum airflow of 66.17 CFM and a noise level of ≤25.6dB(A), ensuring quiet operation while maintaining efficient cooling. The PS120SE’s additional heat pipes and dual fans may provide a slight edge in thermal performance, especially during heavy workloads.

Compatibility

Both coolers are compatible with a variety of CPU sockets. The Assassin King supports Intel sockets 115X, 1200, 1700, and AMD AM4, while the PS120SE covers a broader range, including Intel LGA1700, 1150, 1151, and AMD AM4/AM5. This makes the PS120SE more versatile for users with different CPU platforms. Additionally, both products come with the necessary mounting hardware for installation, ensuring compatibility with a wide range of cases.

Installation Process

The installation process for both coolers is user-friendly, with mounting brackets provided for various CPU sockets. The Thermalright Assassin King’s design allows for straightforward installation with its metal fasteners, while the PS120SE includes detailed installation instructions to aid users. However, due to its larger size, the PS120SE may require more space within the case, which could complicate installation in tighter builds.

Aesthetic Appeal

Aesthetic appeal is a key consideration for many PC builders. The Assassin King features ARGB lighting effects that are colorful and vibrant, adding a stylish touch to any setup. The PS120SE takes this a step further with high-brightness LED fans that offer up to 17 different lighting modes, allowing users to synchronize colors with their motherboard. If visual customization is a priority, the PS120SE may be the better choice.

Pricing

Pricing is a crucial factor in any comparison. The Thermalright Assassin King 120 SE is priced at $19.82, making it about 43% cheaper than the PS120SE, which retails for $34.94. This price difference could be significant for budget-conscious consumers who still seek reliable cooling solutions. However, the additional features and performance of the PS120SE may justify the higher cost for users seeking the best cooling performance.

Brand Reputation

Thermalright has been a respected name in the cooling solutions market for over 20 years, known for their dedication to quality and innovation. Both the Assassin King and PS120SE have been designed with this expertise, ensuring that users receive reliable products. The company’s reputation for effective cooling solutions makes either choice a solid investment, but the PS120SE’s advanced features may appeal more to enthusiasts.

Which should you buy?

Deciding between the Thermalright Assassin King 120 SE and the Thermalright PS120SE largely depends on your specific needs and budget. If you are looking for an economical option that still delivers reliable performance, the Assassin King is a commendable choice at $19.82. However, if you prioritize enhanced cooling capabilities, aesthetic customization, and broader compatibility, the PS120SE, despite its higher price of $34.94, could be worth the investment. In summary, both coolers have their strengths, and the right choice hinges on your individual requirements and preferences.
