Overview of Thermalright Peerless Assassin 120 Digital ARGB Black
The Thermalright Peerless Assassin 120 Digital ARGB Black is a high-performance CPU cooler priced at C$62.90. It features a dual tower design and is equipped with dual fans, providing effective cooling capabilities. With a maximum fan speed of 1850 RPM and an air volume of 88.89 CFM, this cooler is designed to efficiently dissipate heat from the CPU, ensuring optimal performance during heavy loads.
This cooler boasts six pure copper heat pipes and a copper base that facilitate excellent thermal conductivity. The overall height of 162mm makes it compatible with most mainstream ATX cases. Furthermore, the magnetic top cover and digital display board add a modern touch, enhancing both aesthetics and functionality. The TRCC software allows users to monitor and adjust temperature parameters easily, making it a versatile choice for gamers and PC enthusiasts.
Overview of Thermalright Assassin King 120 SE
The Thermalright Assassin King 120 SE ARGB CPU Air Cooler is a more budget-friendly option, priced at C$24.59. This cooler features a compact design, measuring 120mm in length, 73mm in width, and 148mm in height, making it suitable for medium-sized computer cases. Despite its smaller size, it delivers respectable cooling performance with a fan speed of 1550 RPM and an airflow of 66.17 CFM.
This model is constructed with five 6mm heat pipes employing AGHP III technology, which helps mitigate the inverse gravity effect during operation. The cooler is compatible with both Intel and AMD platforms, featuring metal fasteners for easy installation. It also includes a PWM fan that operates quietly, with a noise level of ≤25.6 dB(A), allowing for a quieter computing experience without sacrificing cooling efficiency.
Performance Comparison
When it comes to performance, the Thermalright Peerless Assassin 120 Digital ARGB Black significantly outperforms the Assassin King 120 SE. With a maximum fan speed of 1850 RPM compared to the 1550 RPM of the Assassin King, the Peerless Assassin can move more air, resulting in a higher airflow of 88.89 CFM versus 66.17 CFM. This higher airflow translates to better heat dissipation, crucial for maintaining optimal CPU temperatures during intense gaming or computational tasks.
Moreover, the dual-fan setup of the Peerless Assassin provides a substantial edge in cooling performance, enabling it to handle higher thermal loads more efficiently. The Assassin King, while still capable, is better suited for users with moderate cooling needs or those seeking a more compact and quieter solution.
Noise Levels
Both coolers operate at a similar noise level, with the Thermalright Peerless Assassin 120 Digital ARGB Black rated at ≤25.6 dB(A) and the Assassin King 120 SE also at ≤25.6 dB(A). This means that neither cooler is particularly loud, making them suitable for users concerned about noise. However, the design of the Peerless Assassin, with its dual fans and advanced features, may produce slightly more noise under full load, although it compensates with enhanced cooling performance.
For users who prioritise a silent operation, the Assassin King is an excellent choice, but those needing superior cooling are likely to find the noise levels of the Peerless Assassin acceptable in exchange for its enhanced performance.
Aesthetics and Build Quality
In terms of design, the Thermalright Peerless Assassin 120 Digital ARGB Black stands out with its modern aesthetic, featuring a digital display board and a magnetic top cover. The dual tower and dual fan design not only enhance its cooling capabilities but also give it a sleek and contemporary look that can complement any gaming setup.
On the other hand, the Thermalright Assassin King 120 SE, while functional, has a more straightforward design. It focuses on delivering performance over visual appeal, making it suitable for users who prefer a more utilitarian approach to their build. Both coolers are well-constructed, but if aesthetics play a significant role in your decision, the Peerless Assassin is likely the more attractive option.
Compatibility
The Thermalright Peerless Assassin 120 Digital ARGB Black has a height of 162mm, making it compatible with most mainstream ATX cases. Its dual-fan design requires adequate space but offers significant cooling power for high-performance CPUs. This cooler is particularly suitable for users with larger builds who require effective heat management.
In contrast, the Assassin King 120 SE has a more compact height of 148mm, making it easier to fit into smaller cases. It supports a range of Intel and AMD sockets, including Intel 115X/1200/1700/17XX and AMD AM4/AM5, providing versatility for different builds. While both coolers offer good compatibility, the choice between them may depend on the size of your computer case and intended CPU.
Pricing Comparison
The pricing difference between the two coolers is substantial, with the Thermalright Peerless Assassin 120 Digital ARGB Black priced at C$62.90, while the Assassin King 120 SE is significantly cheaper at C$24.59. This price difference reflects the advanced features and performance capabilities of the Peerless Assassin. For users on a budget or those with moderate cooling needs, the Assassin King offers a compelling value proposition without breaking the bank.
However, for enthusiasts looking for superior performance and aesthetics, the investment in the Peerless Assassin could be worthwhile. Ultimately, the best choice will depend on your specific needs and budget.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black and the Assassin King 120 SE ultimately hinges on your cooling needs and budget. If you seek superior performance, aesthetic appeal, and advanced features, the Peerless Assassin is the clear winner, justifying its higher price tag of C$62.90.
