Dimension comparison
Price Comparison
The Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is priced at C$32.90, while the Thermalright AXP120-X67 Black ARGB Low Profile CPU Cooler comes in at a higher price of C$38.79. This price difference of C$5.89 may influence budget-conscious buyers, especially considering that both products are from the same brand and serve similar cooling functions. The Assassin X 120R offers a more cost-effective solution without compromising on performance, making it an appealing option for users looking for quality cooling without a premium price tag.
Design and Aesthetics
When it comes to design, both coolers boast attractive aesthetics, yet they cater to different user preferences. The Assassin X 120R features a digital screen on its top cover, enhancing its visual appeal while allowing for heat dissipation efficiency. Its overall dimensions are 120x71x151mm, which is a standard size for tower coolers. On the other hand, the AXP120-X67 has a low-profile design, measuring 123.5x120x67mm, which is particularly advantageous for compact builds. The ARGB lighting on both units allows for vibrant colour synchronisation with the motherboard, but the Assassin X 120R might appeal more to users seeking a more pronounced lighting effect due to its larger dimensions and design features.
Cooling Performance
In terms of cooling performance, the Assassin X 120R has a fan speed of 2000 RPM and an airflow rating of 70.84 CFM, producing a wind pressure of 2.63mm H2O. This combination is designed for effective heat dissipation, making it suitable for high-performance CPUs. Conversely, the AXP120-X67 operates at a lower fan speed of 1800 RPM with a maximum airflow of 59 CFM. While still effective, the slightly lower specifications may result in reduced cooling efficiency under heavy loads compared to the Assassin X 120R. For users prioritising maximum cooling performance, the Assassin X 120R could be the preferable choice.
Noise Levels
Noise levels are a crucial consideration for many users, especially in quieter environments. The Assassin X 120R operates at a noise level of ≤29.8dB(A), which is reasonable for a cooler of its size and performance capabilities. In comparison, the AXP120-X67 boasts a lower noise level of ≤26.1dB(A), making it a quieter option. This 3.7dB difference may be significant for those who prefer a silent operation during intensive tasks or gaming sessions. Therefore, if noise reduction is a top priority, the AXP120-X67 could be the better option.
Compatibility
Both coolers offer extensive compatibility, supporting various Intel and AMD sockets. The Assassin X 120R is compatible with Intel’s LGA 1851/1700/1150/1151/1155/1156/1200 and AMD’s AM4/AM5 sockets. Meanwhile, the AXP120-X67 supports Intel’s 1700/1150/1151/1155/1156/1200/2011/2066/17XX and AMD’s AM4. Both products provide the necessary installation accessories and instructions, ensuring that users can install them with ease across multiple platforms. While both offer strong compatibility, the Assassin X 120R’s support for newer AMD sockets may give it an edge for users with the latest hardware.
Features and Technology
In terms of features, the Assassin X 120R boasts a digital screen that allows users to monitor temperatures and system status via TRCC software, enhancing user interactivity. The ARGB lighting can be synchronised with a 5V 3-pin motherboard header, offering aesthetic versatility. On the other hand, the AXP120-X67 employs AGHP (Advanced Gravity Heat Pipe) technology, which helps mitigate the effects of orientation on heat dissipation. While both coolers feature ARGB lighting, the unique software capabilities of the Assassin X 120R may attract tech-savvy users who appreciate real-time monitoring and customisation.
Ease of Installation
Installation ease is essential for users who may not be highly experienced with PC building. Both coolers come with installation accessories and manuals for user convenience. The Assassin X 120R’s design allows for straightforward installation on a variety of platforms, provided that users adhere to the guidelines. The AXP120-X67, with its low-profile design, is also designed for easy installation, particularly in compact cases. However, it specifically notes the need for the original backplate of the motherboard for AMD installation, which could be a slight drawback for some users. Overall, both coolers are designed for user-friendliness, but the Assassin X 120R may offer a more universal experience.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright AXP120-X67 Black ARGB Low Profile CPU Cooler ultimately depends on your specific needs and preferences. If you prioritise cooling performance, extensive compatibility, and interactive features, the Assassin X 120R stands out as the better option, especially given its lower price of C$32.90. However, if a quieter operation and low-profile design for compact builds are more critical for you, the AXP120-X67 at C$38.79 could be the ideal choice. Both coolers offer quality performance, but your particular use case will guide the best selection.
