Dimension comparison
Overview of the Coolers
When comparing the Cooler Master Hyper 212 Halo Black and the Thermalright Peerless Assassin 120 SE, it's evident that both coolers offer unique advantages. The Cooler Master Hyper 212 Halo Black is priced at $34.99, while the Thermalright Peerless Assassin 120 SE costs $32.90. This makes the Thermalright about 3% cheaper than its competitor. However, the choice between them will depend on specific cooling needs and aesthetic preferences.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 120 SE boasts six heat pipes, contributing to its high efficiency. The design includes AGHP technology, which enhances heat exchange and ensures stable performance. On the other hand, the Cooler Master Hyper 212 Halo Black features four copper heat pipes, specifically designed to deliver optimal cooling for AMD R7 and Intel i7 processors. While both coolers provide excellent cooling potential, the Peerless Assassin may edge out slightly due to its additional heat pipes.
Design and Aesthetics
The Cooler Master Hyper 212 Halo Black showcases a minimalistic yet modern design with its jet-black aluminum top cover and dual-loop ARGB lighting that enhances its visual appeal. In contrast, the Thermalright Peerless Assassin 120 SE features an anodized brushed black top cover and an offset asymmetric layout. While both coolers are aesthetically pleasing, the Cooler Master might attract users looking for vibrant RGB lighting, whereas the Thermalright appeals to those favoring a more understated design.
Fan Performance
Fan performance significantly affects the overall efficiency of CPU coolers. The Cooler Master Hyper 212 Halo Black is equipped with a 120 Halo² PWM fan that allows for adjustable speeds ranging from 690 to 1,800 RPM. This flexibility helps balance noise levels and airflow. Conversely, the Thermalright Peerless Assassin 120 SE comes with dual TL-C12C PWM fans, which operate at a maximum speed of 1,550 RPM. Although the Cooler Master has a higher maximum RPM, the Peerless Assassin's dual fans may provide better airflow due to their dual configuration.
Compatibility
Both coolers are designed for compatibility with a wide range of CPU sockets. The Cooler Master Hyper 212 Halo Black supports AMD Ryzen AM5 and AM4, as well as Intel LGA 1851, 1700, and 1200 brackets. Similarly, the Thermalright Peerless Assassin 120 SE is compatible with various AMD and Intel sockets, including AM4 and AM5, as well as LGA 1700 and 1200. While both coolers offer broad compatibility, users should verify their specific motherboard requirements for installation, especially with the Peerless Assassin, which requires the original motherboard's backplate.
Installation Ease
Installation is a crucial factor in selecting a CPU cooler. The Cooler Master Hyper 212 Halo Black features redesigned brackets that simplify the installation process across both AMD and Intel platforms. On the other hand, the Thermalright Peerless Assassin 120 SE includes an SS2 install system with a metal pressure plate for better contact with the CPU. While both coolers are designed for easy installation, the Cooler Master may be easier for users who prioritize a straightforward setup without additional components.
Noise Levels
Noise levels are an essential consideration for many PC builders. The Cooler Master Hyper 212 Halo Black operates at a minimum fan speed of 690 RPM, potentially offering quieter performance during low-load scenarios. In contrast, the Thermalright Peerless Assassin 120 SE has a rated noise level of ≤25.6 dB(A) at its maximum fan speed. While both coolers are designed to minimize noise, the Cooler Master’s adjustable fan speed allows users to tailor the noise output to their preferences more effectively.
Which should you buy?
Ultimately, the choice between the Cooler Master Hyper 212 Halo Black and the Thermalright Peerless Assassin 120 SE will depend on your specific needs. If you prioritize cooling performance and aesthetic features like RGB lighting, the Cooler Master might be the better option. However, if you are looking for a slightly more budget-friendly cooler with excellent airflow, the Thermalright Peerless Assassin could be the ideal choice. Both coolers provide solid performance, so your decision should hinge on your aesthetic preferences, budget, and installation needs.
