Overview of the Brands

Both products come from Thermalright, a Taiwanese brand with over 20 years of experience in the development of computer accessories. Their reputation in the market is solid, especially among PC enthusiasts. This longevity assures consumers of the brand's commitment to quality and innovation. With a focus on R&D, Thermalright has developed a variety of cooling solutions, including the Peerless Assassin 120 SE ARGB and the AXP90 X53, each tailored for different user needs and setups.

Design and Build Quality

The Thermalright Peerless Assassin 120 SE ARGB features a double tower design, measuring 125mm by 135mm by 155mm, which allows for robust heat dissipation. This cooler is equipped with two PWM fans that provide excellent airflow with a maximum airflow of 66.17 CFM. On the other hand, the AXP90 X53 is a low-profile cooler, standing at just 53mm tall, making it ideal for compact ITX builds. Its design is optimised for smaller motherboards while still ensuring effective cooling thanks to a 92mm slim PWM fan capable of reaching 2700 RPM. This difference in design highlights the two coolers' target audiences—one for standard builds and the other for space-constrained setups.

Performance Metrics

In terms of cooling performance, the Peerless Assassin 120 SE ARGB has a thermal design power (TDP) rating of 120 to 245W, making it suitable for high-performance CPUs. This ability is supported by its six heat pipes and efficient airflow from its dual fans. Conversely, the AXP90 X53, with its 4x6mm heat pipes, also employs advanced AGHP technology for enhanced heat transfer, but has a narrower TDP capability due to its smaller profile. The AXP90 X53 is designed for mid-range CPU cooling, highlighting its focus on compatibility with smaller cases while still delivering adequate cooling performance.

Noise Levels

Noise performance is essential for many users, especially those who prefer a quieter computing environment. The Peerless Assassin 120 SE ARGB operates at a noise level of 25.6 dB(A), which is relatively quiet for a cooler of its size and capabilities. The dual fans ensure effective cooling without generating excessive noise. In contrast, while specific noise levels for the AXP90 X53 are not mentioned, the technology used in its fan design suggests a focus on durability and reduced noise, making it a viable option for users who prioritise a quieter operation in compact builds.

Compatibility

Compatibility is a significant factor when selecting a CPU cooler. The Peerless Assassin 120 SE ARGB supports a wide array of Intel sockets, including 115X, 1200, 1700, and AMD AM4, making it a versatile choice for many builds. The AXP90 X53 also boasts broad compatibility, supporting Intel LGA1700 and various AMD sockets, including AM4 and AM5. However, the AXP90 X53’s low profile design allows it to fit in tighter spaces, which may make it the better choice for users with small form-factor cases.

Installation Process

In terms of installation, the Peerless Assassin 120 SE ARGB is straightforward, thanks to its included metal fasteners for both Intel and AMD platforms. It comes with everything needed for a hassle-free setup. The AXP90 X53, while also designed for easy installation, includes specific instructions for those using certain motherboard configurations, which may require additional steps with long screws. This could be a consideration for less experienced users who may prefer a more seamless installation process.

Pricing

When it comes to price, the Thermalright Peerless Assassin 120 SE ARGB is currently priced at C$46.90, while the AXP90 X53 is slightly more affordable at C$45.99. The price difference is minor, but it may influence the decision for budget-conscious consumers. Given the features and performance capabilities of both coolers, each offers good value for its price point, appealing to different segments of the market.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE ARGB and the AXP90 X53 largely depends on your specific needs. If you require robust cooling for high-performance CPUs and have the space for a larger cooler, the Peerless Assassin 120 SE ARGB is the better option, offering superior thermal performance and airflow. However, if you are working with a compact ITX setup and need a low-profile cooler, the AXP90 X53 excels in compatibility and space-saving design. Both are excellent choices within their intended categories, but your decision should align with your build requirements and performance expectations.
