The AXP90 X47 also employs AGHP technology, enhancing its cooling performance through the secondary welding of heat pipes and fins.
Performance Comparison
When it comes to cooling performance, the Thermalright Assassin X 120 SE outshines its counterpart due to its larger fan and higher air flow. With an air flow rate of 66.17 CFM compared to the AXP90 X47's 42.58 CFM, the Assassin X 120 SE is better equipped to dissipate heat in more demanding scenarios. However, the AXP90 X47's design allows it to excel in space-constrained environments, indicating that its performance is tailored for specific user needs rather than competing directly with the Assassin X 120 SE.
Noise Levels
Noise output is a critical factor for many users, and both coolers perform admirably in this regard. The Thermalright Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), while the AXP90 X47 is slightly quieter at 22.4 dB(A). This 3.2 dB(A) difference may be noticeable in very quiet environments, making the AXP90 X47 a better choice for users prioritizing silence over maximum cooling performance.
Compatibility and Installation
In terms of compatibility, both coolers offer extensive support for various Intel and AMD sockets. The Assassin X 120 SE is compatible with Intel 115X/1200/1700 and AMD AM4 sockets, while the AXP90 X47 supports Intel LGA1700/1150/1151/1155/1156/1200 and AMD AM4/AM5. This broad compatibility ensures that both coolers can fit a wide range of builds. However, the AXP90 X47’s low-profile design makes it particularly advantageous for smaller form factor cases, where installation space is limited.
Build Quality and Materials
Both products are crafted by Thermalright, a brand with over 20 years of experience in the computer cooling market. The Assassin X 120 SE is built with aluminum heat sinks and features long-lasting S-FDB bearings, promising a service life of up to 20,000 hours. Meanwhile, the AXP90 X47 is made from pure copper, which significantly enhances its oxidation resistance and cooling efficiency. This focus on quality materials highlights the thoughtful engineering behind each product, catering to different user preferences for cooling technologies.
Aesthetic Appeal
The aesthetic aspects of cooling solutions can be particularly important for users with transparent cases or custom builds. The Thermalright Assassin X 120 SE features ARGB lighting, allowing for customizable lighting effects that can enhance the overall look of your build. On the other hand, the AXP90 X47 does not boast any RGB features, focusing instead on a sleek and compact design. Users who appreciate visual flair will likely lean toward the Assassin X 120 SE, while those prioritizing functionality may prefer the understated appearance of the AXP90 X47.
Which should you buy?
Ultimately, the choice between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright AXP90 X47 Full Low Profile CPU Cooler depends on individual needs and preferences. The Assassin X 120 SE is ideal for users seeking high performance and aesthetic appeal at a lower price point of C$24.29.
