Price Comparison
The Cooler Master Hyper 212 Halo Black is priced at C$43.95, while the Thermalright Assassin King 120 SE ARGB is significantly cheaper at C$24.59. This price difference of C$19.36 makes the Thermalright a more budget-friendly option for consumers looking to save money without compromising too much on performance. The Cooler Master offers premium features that may justify its higher price, but for those on a tighter budget, the Thermalright presents a compelling alternative.
Design and Aesthetics
The Cooler Master Hyper 212 Halo Black features a sleek design with a black aluminum top cover, which adds a modern touch to any build. Its dual-loop ARGB lighting allows for stunning visual effects and provides a clean look. In contrast, the Thermalright Assassin King 120 SE ARGB showcases its own colourful ARGB light effects. Although it uses a standard 120mm PWM fan, its overall aesthetic might not be as refined as that of the Cooler Master. Ultimately, while both coolers have appealing designs, the Cooler Master may appeal more to those prioritizing a sophisticated look in their builds.
Cooling Performance
When it comes to cooling performance, the Cooler Master Hyper 212 Halo Black boasts enlarged fan blades designed to deliver enhanced airflow and cooling efficiency. This feature is particularly beneficial for users with high-performance CPUs that generate considerable heat. The Thermalright Assassin King 120 SE ARGB, on the other hand, employs a 120mm fan that achieves a maximum airflow of 66.17 CFM, which is decent for its class. However, the specific cooling efficiency details of the Cooler Master, paired with its larger fan blades, suggest it may offer superior cooling performance under heavy loads.
Noise Levels
The Thermalright Assassin King 120 SE ARGB operates at a noise level of less than 25.6 dB(A), making it relatively quiet during operation. This low noise level is an attractive feature for users looking for a cooler that won't disrupt their environment. The Cooler Master Hyper 212 Halo Black does not specify its noise levels, but its design and fan configuration suggest that it is built for performance, possibly at the expense of quieter operation. Therefore, if silence is a priority, the Thermalright might be the better choice.
Compatibility
In terms of compatibility, the Cooler Master Hyper 212 Halo Black has a compact height of 154mm, which allows it to fit into a wide range of chassis without sacrificing performance. This makes it a versatile option for various builds. The Thermalright Assassin King 120 SE ARGB is compatible with multiple CPU sockets, including Intel's 115X/1200/1700/17XX and AMD's AM4/AM5, and has a height of 148mm. While both coolers offer good compatibility, the Cooler Master's slightly taller profile could limit its use in particularly tight cases.
Brand Reputation
Cooler Master is a well-established brand known for its quality and innovation in cooling solutions. The Hyper 212 series has a solid reputation among PC builders for its reliable performance. On the other hand, Thermalright, while also reputable, may not have the same level of brand recognition as Cooler Master. With over 20 years in the market, Thermalright has gained popularity, especially in the player market, but the choice may boil down to personal preference and past experiences with either brand.
Installation Process
Both the Cooler Master Hyper 212 Halo Black and the Thermalright Assassin King 120 SE ARGB feature straightforward installation processes. The Cooler Master comes with a redesigned hybrid frame that maintains stability and makes installation easier. The Thermalright cooler includes metal fasteners compatible with both Intel and AMD platforms, ensuring a secure fit. While neither cooler presents significant installation challenges, the Cooler Master’s design may appeal more to users looking for enhanced stability during installation.
Which should you buy?
Choosing between the Cooler Master Hyper 212 Halo Black and the Thermalright Assassin King 120 SE ARGB ultimately depends on your priorities. If you are looking for superior cooling performance, advanced features, and a refined design, the Cooler Master is worth the C$43.95 investment. However, if budget constraints are a significant factor, the Thermalright offers solid performance and a visually appealing design at a much lower price of C$24.59. Consider your specific needs—whether it's performance, aesthetics, or budget—and make your choice accordingly.
