Overview of the Coolers
The Cooler Master Hyper 212 Halo Black CPU Air Cooler is priced at $34.99, while the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler is significantly cheaper at $19.82, making it about 43% less expensive. Both coolers target similar users, offering efficient cooling solutions for a range of compatible CPUs, but they come with distinct features that cater to different preferences and needs.
Design and Aesthetics
In terms of design, the Cooler Master Hyper 212 Halo Black boasts a sleek, minimalistic black aesthetic with an aluminum top cover, enhancing its visual appeal. Its dual-loop ARGB rings provide vibrant lighting, which can be a significant attraction for users who enjoy customizable lighting setups. Conversely, the Thermalright Assassin King 120 SE White features a clean white design that may appeal to those who prefer a lighter or more neutral color scheme in their builds. Both designs are aimed at enhancing the overall look of a gaming setup, but the choice between them will depend on personal taste.
Cooling Performance
The Cooler Master Hyper 212 Halo Black features four copper heat pipes that ensure optimal cooling performance for AMD R7 and Intel i7 processors. With a PWM fan that operates between 690 to 1,800 RPM, it balances noise and airflow effectively. In comparison, the Thermalright Assassin King 120 SE White utilizes five heat pipes and a PWM fan that runs at a maximum speed of 1,550 RPM, providing decent airflow but slightly less variable speed compared to Cooler Master. While both products claim to deliver efficient cooling, the Hyper 212 may have an edge in versatility due to its broader RPM range.
Compatibility
Both coolers offer versatile compatibility with various CPU sockets. The Cooler Master Hyper 212 Halo Black supports AMD Ryzen AM5|AM4 and Intel LGA 1851|1700|1200 brackets, which makes it suitable for a wide array of modern CPUs. The Thermalright Assassin King 120 SE White provides compatibility with AMD AM4/AM5 and Intel LGA 1700/1150/1151/1200/1851, ensuring a similar range of compatibility. However, the Cooler Master’s installation brackets are redesigned to simplify the installation process, potentially giving it an advantage in terms of user-friendliness.
Noise Levels
Noise levels are a critical factor for many users, especially those who prioritize a quiet computing environment. The Cooler Master Hyper 212 Halo Black is designed with a PWM fan that optimizes airflow while minimizing noise, though specific decibel ratings are not provided. On the other hand, the Thermalright Assassin King 120 SE White claims a noise level of less than 25.6 dB(A), which suggests that it operates quietly. While both coolers aim to provide low-noise operation, the Thermalright model may be the quieter option for those who are sensitive to sound.
Installation Process
The installation process can be a hassle for many users, but both coolers strive to simplify this experience. The Cooler Master Hyper 212 Halo Black features redesigned brackets that enhance compatibility and ease of installation on the latest platforms. In comparison, the Thermalright Assassin King 120 SE White includes metal fasteners for better installation on both AMD and Intel platforms. While both products offer straightforward installation, the Cooler Master may appeal more to users looking for a user-friendly setup due to its updated bracket design.
Pricing and Value
When it comes to pricing, the Cooler Master Hyper 212 Halo Black is priced at $34.99, while the Thermalright Assassin King 120 SE White is available for a much lower price of $19.82. This represents a price difference of approximately $15.17, making the Thermalright cooler about 43% cheaper than its competitor. For budget-conscious consumers, the Thermalright model offers excellent value without compromising essential features, making it a compelling option for those looking for efficient cooling on a budget.
Which should you buy?
Ultimately, the choice between the Cooler Master Hyper 212 Halo Black and the Thermalright Assassin King 120 SE White will depend on individual preferences and specific needs. If aesthetics, customizable lighting, and a slightly more robust cooling performance are your priorities, the Cooler Master Hyper 212 may be the better choice.
