Dimension comparison
Price Comparison
The ID-COOLING FROZN A720 Black is priced at C$110.92, while the Thermalright Peerless Assassin 120 Black is significantly more affordable at C$54.90. This substantial price difference of C$56.02 may influence budget-conscious consumers. While the FROZN A720 offers advanced features and performance capabilities, the Peerless Assassin 120 provides a cost-effective option for users looking for solid cooling without breaking the bank. If budget is a primary concern, the Peerless Assassin stands out as the more economical choice.
Design and Aesthetic Appeal
The ID-COOLING FROZN A720 Black features a sleek all-black design that complements various computer setups, particularly those with dark interiors. This dual-tower cooler stands at a height of 6.4 inches, allowing it to fit comfortably in most cases. In contrast, the Thermalright Peerless Assassin 120 Black also sports a stylish black finish but has a more compact design with dimensions of 125x135x157mm. The aesthetic appeal is subjective, yet both coolers have been designed to seamlessly blend into modern builds, making either a visually pleasing addition to your system.
Cooling Performance
When it comes to cooling performance, the ID-COOLING FROZN A720 Black is equipped with two 140mm fans that provide a maximum airflow of 98.6 CFM, while maintaining a noise level of 33.5 dB(A). This configuration, along with seven copper heat pipes, ensures efficient heat dissipation. On the other hand, the Thermalright Peerless Assassin 120 Black utilises two 120mm PWM fans, achieving a maximum airflow of 66.17 CFM with a quieter noise level of 25.6 dB(A). While the FROZN A720 has a higher airflow, the Peerless Assassin operates more quietly, making it suitable for users who prefer a quieter system.
Installation Process
Both the ID-COOLING FROZN A720 Black and the Thermalright Peerless Assassin 120 Black offer hassle-free installation processes, compatible with a range of Intel and AMD sockets. The FROZN A720 is noted for its ease of installation across various platforms, while the Peerless Assassin also includes metal fasteners to facilitate a straightforward setup. However, the specific compatibility of the FROZN A720 with a wider range of Intel sockets, including LGA2011/1700/1851/1200/1150/1151/1155/1156, gives it an edge for users with diverse system configurations, although both coolers are designed to accommodate modern CPUs.
Noise Levels
In terms of noise levels, the Thermalright Peerless Assassin 120 Black operates at a maximum of 25.6 dB(A), which is quite impressive for a CPU cooler, especially under load. The ID-COOLING FROZN A720 Black, while also designed for low noise with its PWM fans, operates at a higher maximum noise level of 33.5 dB(A). For users prioritising a quieter operation, the Peerless Assassin would be the better choice, whereas those seeking maximum cooling performance might be willing to tolerate the slightly higher noise output of the FROZN A720.
Heat Dissipation Technology
The ID-COOLING FROZN A720 Black employs seven Ф6mm copper heat pipes working in tandem with its dual-tower design to ensure superior heat absorption and dissipation. This advanced technology allows for efficient thermal management under heavy loads. Conversely, the Thermalright Peerless Assassin 120 Black utilises six 6mm heat pipes and an offset asymmetric layout to enhance its cooling capabilities. While both coolers aim for effective heat dissipation, the FROZN A720’s additional heat pipe may provide an edge in extreme cooling scenarios.
RAM Compatibility
The ID-COOLING FROZN A720 Black provides 58mm clearance for RAM when using a single fan configuration, making it an excellent choice for users with taller RAM modules. The Thermalright Peerless Assassin 120 Black does not specify its RAM clearance but is designed to fit comfortably in most builds. For users concerned about RAM height and compatibility with their CPU cooler, the FROZN A720's specific measurement gives it a clear advantage, ensuring that high-profile RAM won't interfere with its installation.
Which should you buy?
Choosing between the ID-COOLING FROZN A720 Black and the Thermalright Peerless Assassin 120 Black ultimately depends on your specific needs and budget. If you're looking for superior cooling performance and are willing to invest more, the FROZN A720 with its higher airflow and advanced heat dissipation technology is the better option. However, if you are budget-conscious and prefer a quieter operation with solid cooling capabilities, the Peerless Assassin 120 presents a compelling choice. Each cooler has its strengths, making the decision highly personal based on performance needs and financial considerations.
