Dimension comparison
Overview of Thermalright Peerless Assassin 120 SE ARGB and Thermalright AXP120-X67
The Thermalright Peerless Assassin 120 SE ARGB is priced at C$46.90, while the Thermalright AXP120-X67 is more affordable at C$36.90. Both products are manufactured by Thermalright, a brand known for over 20 years in the computer accessory market. This section highlights the premium features and build quality of each cooler, setting the stage for a detailed comparison.
The Peerless Assassin 120 SE ARGB boasts a robust design with dimensions of 125mm x 135mm x 155mm and a weight of 0.97kg. It features dual PWM fans that provide a maximum airflow of 66.17 CFM, ensuring effective cooling performance. In contrast, the AXP120-X67 is more compact, measuring 123.5mm x 120mm x 67mm and weighing significantly less due to its low-profile design, which is advantageous for smaller builds. It offers a maximum airflow of 59 CFM, which is still commendable for its size.
Design and Build Quality
The design and build quality of both coolers are impressive and tailored for different applications. The Peerless Assassin 120 SE ARGB has a dual-tower cooling system that enhances its cooling capability, making it suitable for more demanding CPUs with a thermal design power (TDP) of 120 to 245W. Its aesthetic appeal is heightened by colourful ARGB lighting effects, which can enhance the visual appeal of any gaming rig.
On the other hand, the AXP120-X67's low-profile design, with a height of only 67mm, makes it an ideal choice for compact cases where space is a concern. It also employs a combination of aluminum fins on a copper base which contributes to a balanced performance. Both coolers incorporate the AGHP technique for heat pipes, which helps mitigate the inverse gravity effect, ensuring consistent cooling performance regardless of orientation.
Cooling Performance
Cooling performance is a critical factor when choosing a CPU cooler, and here the Peerless Assassin 120 SE ARGB holds an edge. With a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A), it provides efficient cooling while remaining relatively quiet. This is particularly beneficial for high-performance CPUs that generate significant heat during operation.
The AXP120-X67, while slightly behind in maximum airflow at 59 CFM and a noise level of 26.1 dB(A), still offers adequate cooling for mid-range processors. Its 120mm PWM fan operates at a higher RPM of 1800, but the trade-off is a marginally increased noise level. Therefore, the Peerless Assassin 120 SE ARGB is better suited for users seeking ultimate cooling efficiency, while the AXP120-X67 is sufficient for less demanding setups.
Compatibility
Compatibility is essential for users looking to upgrade their cooling solutions. The Peerless Assassin 120 SE ARGB supports a wide range of sockets, including Intel's 115X/1200/1700 and AMD's AM4, making it versatile for various builds. This comprehensive compatibility ensures that users can easily install it on most modern CPUs without additional purchases.
The AXP120-X67 also supports multiple sockets, including Intel’s 1700/1150/1151/1155/1156/1200/2011/2066 and AMD’s AM4. Both coolers come equipped with the necessary mounting hardware for easy installation. Thus, users can be confident that either cooler will work with their setup, though the Peerless Assassin offers slightly more flexibility due to its broader socket support.
Noise Levels
Noise levels are a significant consideration for many users, particularly in quiet environments. The Peerless Assassin 120 SE ARGB operates at a maximum noise level of 25.6 dB(A), making it one of the quieter options available in its category. This feature is particularly appealing for gamers who prefer a silent experience while playing.
In comparison, the AXP120-X67 has a higher maximum noise level of 26.1 dB(A). While the difference is minimal, it can still be noticeable in quieter settings. Users who prioritize low noise output during operation will likely lean towards the Peerless Assassin for a more serene computing experience.
Aesthetic Appeal
Aesthetic features can significantly influence a buyer's decision, especially for those who build visually appealing setups. The Peerless Assassin 120 SE ARGB comes with ARGB lighting that adds a vibrant touch to any build, allowing for customisation and synchronization with other RGB components. This makes it an attractive option for gamers and PC builders who value visual flair.
The AXP120-X67, while not equipped with RGB features, boasts a sleek and understated design that fits well in minimalist builds. Its low-profile nature allows it to blend seamlessly into compact cases without drawing too much attention. Therefore, the choice between these coolers may come down to personal preference regarding aesthetics.
Price Consideration
Price is always a crucial factor in any purchasing decision. The Thermalright Peerless Assassin 120 SE ARGB is priced at C$46.90, whereas the AXP120-X67 is more budget-friendly at C$36.90. While the Peerless Assassin offers superior features and performance, the AXP120-X67 represents a solid value for users who do not require high-end cooling capabilities.
For users on a tight budget or those with less demanding cooling needs, the AXP120-X67 provides excellent performance without breaking the bank. However, for those looking for advanced cooling solutions and aesthetic enhancements, the Peerless Assassin justifies its higher price point.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE ARGB and the Thermalright AXP120-X67 ultimately depends on your specific needs and preferences. If you require superior cooling performance, aesthetic appeal, and more extensive compatibility, the Peerless Assassin 120 SE ARGB is the better choice, despite its higher price of C$46.90. On the other hand, if you seek a more compact and budget-friendly solution for mid-range CPUs, the AXP120-X67 at C$36.90 offers solid performance and reliable cooling. Assess your cooling requirements and budget to make the best decision for your build.
