Dimension comparison
Overview of Thermalright Products
In this comparison, we will examine two CPU coolers from Thermalright: the Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler and the Thermalright Assassin X 120 SE ARGB CPU Air Cooler. The AXP90 X53 is priced at C$45.99, while the Assassin X 120 SE is more budget-friendly at C$24.29. Both products are designed to enhance cooling performance, but they cater to different user needs and system configurations.
Design and Build Quality
The AXP90 X53 features a sleek low-profile design, making it suitable for compact spaces, with an overall height of just 53mm. This is particularly advantageous for ITX builds where space is at a premium. In contrast, the Assassin X 120 SE has a more traditional tower design, measuring 148mm in height. This size allows for greater cooling potential, especially in medium-sized cases, but may not fit in smaller builds. Both coolers utilize high-quality materials, with the AXP90 X53 employing advanced AGHP technology to prevent gravity-related cooling issues, while the Assassin X 120 SE also benefits from the same technology.
Cooling Performance
The AXP90 X53 comes equipped with a 92mm slim PWM fan capable of reaching speeds up to 2700 RPM. This high-speed capability allows the AXP90 X53 to deliver efficient cooling, especially in cramped environments where airflow may be limited. On the other hand, the Assassin X 120 SE features a larger 120mm PWM fan that operates at a maximum speed of 1550 RPM, providing a maximum airflow of 66.17 CFM. While the AXP90 X53 may have a higher RPM, the larger size and design of the Assassin X 120 SE allow it to cool more effectively in larger cases.
Compatibility with CPU Sockets
Both coolers offer broad compatibility with various CPU sockets. The AXP90 X53 supports Intel sockets LGA1700, LGA1150, LGA1151, LGA1155, LGA1156, and LGA1200, as well as AMD AM4 and AM5 sockets. This extensive compatibility makes it a versatile choice for many builds. The Assassin X 120 SE also supports a range of sockets, including Intel 115X, LGA1200, LGA1700, and AMD AM4. While both coolers cater to a wide audience, the AXP90 X53's low-profile design may be more appealing for compact builds, while the Assassin X 120 SE fits standard ATX cases.
Noise Levels
In terms of noise levels, the Assassin X 120 SE operates at a maximum of 25.6 dB(A), ensuring that it provides efficient cooling without excessive noise—a crucial factor for users who prioritise a quiet environment. The AXP90 X53, while not explicitly stated, features a high-speed fan that could potentially produce more noise under load. Users who are sensitive to noise may prefer the quieter operation of the Assassin X 120 SE, especially in home or office settings.
Installation and User Experience
The installation process for both coolers is designed to be user-friendly. The AXP90 X53 includes specific instructions for installation, particularly to address potential conflicts with motherboard components. This attention to detail can ease the installation process for users, particularly those who may not have extensive experience with PC builds. The Assassin X 120 SE also comes with metal fasteners for easy installation across both Intel and AMD platforms. However, its larger size may require careful consideration of case dimensions during installation.
Brand Reputation and Support
Thermalright has built a solid reputation over its 20 years of operation, known for its innovative cooling solutions and quality products. Both coolers benefit from this brand recognition, with users often praising their performance and reliability. The support for installation provided by Thermalright adds value, as users can access manuals and videos to assist with setup. This commitment to customer service is an essential factor for users choosing between products.
Which should you buy?
When deciding between the Thermalright AXP90 X53 and the Thermalright Assassin X 120 SE, consider your specific needs. If you require a low-profile cooler for a compact ITX build, the AXP90 X53 is the clear choice due to its height of just 53mm and strong cooling performance at higher RPMs. However, if you have a standard ATX case and prefer a quieter operation with effective cooling, the Assassin X 120 SE is more suitable, especially given its lower price of C$24.29 compared to the AXP90 X53's C$45.99. Ultimately, your choice should align with your build requirements, budget, and personal preferences for noise levels and cooling efficiency.
