Overview of the Products
When it comes to CPU coolers, the CPU Air Cooler with 4X6mm Heat Pipes and the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler are two popular choices. Both products offer impressive cooling performance but differ significantly in design, price, and features. The CPU Air Cooler is priced at $23.99, while the Thermalright model is about 17% cheaper at $19.82.
Cooling Performance
The CPU Air Cooler with 4X6mm Heat Pipes boasts four 6mm heat pipes, designed to dissipate heat efficiently from your CPU. This cooler is reported to enhance a direct heat pipe contact area of 25mm, ensuring optimal performance even under heavy workloads. On the other hand, the Thermalright Assassin King utilizes five 6mm heat pipes and features AGHP III technique, which helps counteract inverse gravity effects in various orientations. While both coolers provide substantial cooling, the Thermalright may have a slight edge due to its additional heat pipe.
Noise Levels
Noise levels are crucial for users who prefer a quiet computing experience. The CPU Air Cooler operates at a maximum noise level of 26dB(A), which is relatively quiet. Conversely, the Thermalright Assassin King claims a lower maximum noise level of 25.6dB(A). This slight difference may not be perceptible in everyday use, but it does indicate that the Thermalright might be marginally quieter during operation.
Compatibility
Compatibility is a key factor when choosing a CPU cooler. The CPU Air Cooler supports a wide range of Intel and AMD sockets, including LGA 1700, 1155, and AM5/AM4/AM3 series. This broad compatibility ensures that it can fit various processor models. Meanwhile, the Thermalright Assassin King also supports both Intel and AMD sockets, including LGA 1700 and AM4. Both coolers excel in compatibility, making them suitable for a variety of systems.
Fan Features
Fan efficiency is vital for maintaining optimal cooling. The CPU Air Cooler features a 120mm fan that operates at a maximum speed of 1650rpm, delivering a high airflow of 68.2CFM. In comparison, the Thermalright Assassin King is equipped with a 120mm PWM fan that operates at 1550rpm, with an airflow rating of 66.17CFM. While both fans provide excellent airflow, the CPU Air Cooler is slightly more powerful, making it potentially more effective under load.
Design and Aesthetics
Aesthetics can play a significant role in user preference. The CPU Air Cooler comes in a sleek black finish, while the Thermalright Assassin King features a striking white design with ARGB lighting effects. The ARGB lighting can enhance the visual appeal of a gaming setup, making the Thermalright a more attractive option for users who prioritize aesthetics. However, the choice ultimately depends on the user's personal style and case design.
Installation Process
Installation ease is crucial for many users. The CPU Air Cooler offers non-disassembly fan installation, allowing for hassle-free setup without removing the motherboard or RAM. This feature can save time and effort during installation. The Thermalright Assassin King, while also designed for easy installation, does not emphasize this feature as strongly. Users may find the CPU Air Cooler more accessible, especially for those less experienced with PC builds.
Price Comparison
The price difference between the two coolers is notable. The CPU Air Cooler is priced at $23.99, while the Thermalright Assassin King is available for $19.82. This makes the Thermalright about 17% cheaper, which could be a significant factor for budget-conscious consumers. However, the slight price difference may not outweigh the cooling performance and features offered by the CPU Air Cooler for some users.
Which should you buy?
Ultimately, the choice between the CPU Air Cooler with 4X6mm Heat Pipes and the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler boils down to personal preferences and specific needs. If you prioritize a higher cooling performance, compatibility with a wide range of sockets, and easy installation, the CPU Air Cooler may be the better choice for you. Conversely, if you prefer a sleeker design with ARGB lighting and a lower price point, the Thermalright Assassin King is a solid option. Consider your unique requirements and budget to make the best decision for your build.
