Overview of Thermalright AXP90 X53

The Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler is designed for compact builds, offering a height of only 53mm. This cooler features a 92mm slim PWM fan capable of reaching 2700 RPM, providing efficient cooling in tight spaces. With a current price of C$45.99, it aims to create a balance between performance and compact design for users with small form factor cases.

Thermalright has a long-standing reputation, boasting over 20 years of experience in developing computer accessories. The AXP90 X53 leverages advanced AGHP technology to improve heat transfer efficiency significantly. This cooler is particularly suited for small motherboards, making it an ideal choice for ITX cases and users looking to maximise space without compromising on cooling performance.

Overview of Thermalright Assassin X 120 SE

The Thermalright Assassin X 120 SE CPU Air Cooler is a larger option, standing at 148mm tall and priced at C$25.59. It includes a standard 120mm PWM fan that operates at a maximum speed of 1550 RPM, providing a good balance of airflow and noise level, rated at a maximum of 66.17 CFM. This cooler is designed for users who need effective cooling performance in medium-sized cases.

Similar to its counterpart, the Assassin X 120 SE utilises AGHP technology for enhanced heat transfer efficiency. It supports a wide range of CPU sockets, making it versatile for various builds. The cooler's design and material choices, including industrial-strength PBT and PC materials, aim to ensure durability and longevity, with a service life of up to 20,000 hours.

Cooling Performance Comparison

When it comes to cooling performance, the AXP90 X53 features a higher RPM at 2700 compared to the Assassin X 120 SE's 1550 RPM. While the AXP90 X53 is designed for low-profile applications and excels in compact environments, the larger Assassin X 120 SE can provide more airflow thanks to its bigger fan and larger heat sink, making it suitable for moderate to high TDP CPUs.

Both coolers utilise Thermalright's AGHP technology, which helps mitigate the effects of gravity on heat transfer. However, the AXP90 X53's design is more focused on maintaining performance in smaller cases, while the Assassin X 120 SE can handle a broader range of CPU heats due to its increased height and airflow capabilities.

Compatibility with CPU Sockets

The AXP90 X53 supports a variety of CPU sockets, including Intel's LGA1700, 1150, 1151, 1155, 1156, and 1200, as well as AMD's AM4 and AM5. This broad compatibility allows it to work with many modern systems, particularly those that require low-profile cooling solutions.

On the other hand, the Assassin X 120 SE also supports multiple CPU sockets, including Intel's 115X, 1200, 1700, and AMD's AM4. While both coolers offer good compatibility, the choice between them may hinge on the specific CPU socket and case size requirements of your build. The AXP90 X53's low-profile design makes it more suitable for compact systems, whereas the Assassin X 120 SE targets users with more spacious cases.

Installation and User Experience

Installation processes for both coolers are designed to be user-friendly. The AXP90 X53 includes specific instructions for scenarios where its backplane may conflict with motherboard components. Users can follow the provided manual or installation video for guidance, ensuring a smoother setup.

The Assassin X 120 SE also offers a straightforward installation experience, providing metal fasteners for both Intel and AMD platforms. Its design aims for compatibility with medium-sized cases, making it a practical choice for users who might not want to deal with the constraints of tight spaces.

Noise Levels and Operation

Noise level considerations can significantly influence user experience, especially in builds focused on quiet operation. The AXP90 X53's fan can reach high speeds of 2700 RPM, which may produce more noise under load compared to the Assassin X 120 SE, which operates at a maximum of 1550 RPM and is rated for a noise level of 25.6 dB(A).

While both coolers are designed for efficient cooling, the quieter operation of the Assassin X 120 SE may appeal to users prioritising a serene computing environment, whereas the AXP90 X53 may be better for those who need maximum cooling performance in compact systems.

Pricing and Value for Money

The AXP90 X53 is priced at C$45.99, while the Assassin X 120 SE is more affordable at C$25.59. This price difference could influence a buyer's choice, especially for budget-conscious consumers. The higher price of the AXP90 X53 reflects its advanced technology and low-profile design, making it suitable for specific use cases, while the Assassin X 120 SE offers excellent value for its performance and compatibility at a lower price point.

Ultimately, the decision may come down to the specific needs of the user, such as case size, cooling requirements, and budget.

Which should you buy?

The choice between the Thermalright AXP90 X53 and the Thermalright Assassin X 120 SE largely depends on your specific needs. If you are building a compact ITX system and require a cooler that fits in tight spaces, the AXP90 X53 is the better option due to its low-profile design and higher RPM.
