Overview of the Products

In this comparison, we will examine the Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler and the Thermalright Peerless Assassin 120 SE Black CPU Cooler. Both coolers are designed for efficient CPU cooling, but they cater to different needs and preferences. The AXP90 X53 is priced at C$45.99, while the Peerless Assassin 120 SE Black is slightly higher at C$46.79.

Design and Build Quality

The design and build quality of the AXP90 X53 focus on low-profile efficiency, making it ideal for compact ITX cases. Its overall height is just 53mm, allowing it to fit into smaller builds seamlessly. In contrast, the Peerless Assassin 120 SE Black boasts a double tower design with a height of 155mm, providing a more substantial cooling surface area. The materials used in the Peerless Assassin include a blackened nano coating and fully electroplated heat pipes, which enhance its aesthetic appeal and thermal performance.

Cooling Performance

Cooling performance is a critical factor when selecting a CPU cooler. The AXP90 X53 features a 92mm slim PWM fan capable of reaching speeds of 2700 RPM, enabling it to dissipate heat effectively in tight spaces. On the other hand, the Peerless Assassin 120 SE Black employs dual 120mm PWM fans, each running at a maximum speed of 1550 RPM. While the AXP90 X53 is designed for compact builds, the dual fans of the Peerless Assassin significantly increase airflow, offering superior cooling capabilities, particularly for high-performance CPUs.

Compatibility

Compatibility is essential for ensuring that a cooler can be installed on a variety of motherboards. The AXP90 X53 supports a wide range of CPU slots, including Intel's LGA1700, LGA1150, and AMD's AM4/AM5. It comes with corresponding metal mounting fasteners to facilitate installation across different platforms. Similarly, the Peerless Assassin 120 SE Black supports a broad array of CPU slots, including Intel's LGA1150 through LGA1851 and AMD's AM4/AM5, making it versatile for various builds. Both coolers provide the necessary mounting kits for successful installation.

Noise Levels

Noise levels can significantly impact the user experience, especially in a quiet environment. The AXP90 X53, with its 92mm fan, is designed to operate quietly, although specific decibel levels are not provided. The Peerless Assassin 120 SE Black claims a maximum noise level of 25.6 dB(A) with its dual fans, which is relatively quiet for its performance capability. Users looking for a cooler that balances performance and noise may find the Peerless Assassin slightly more appealing due to its stated noise specifications.

Installation Process

Easy installation is a desired feature for many users. The AXP90 X53 includes installation instructions and requires users to adjust the backplane when conflicts with motherboard components arise. This may involve using longer screws for proper installation. The Peerless Assassin 120 SE Black also offers a straightforward installation process, with an included mounting kit for both Intel and AMD platforms, along with installation tutorials. However, the dual tower design may require more space and care during installation compared to the more compact AXP90 X53.

Price Comparison

When it comes to pricing, the AXP90 X53 is available at C$45.99, while the Peerless Assassin 120 SE Black is priced at C$46.79. The price difference of C$0.80 is minimal, especially considering the cooling capabilities offered by the Peerless Assassin with its dual fan setup. Users should weigh their budget against the performance needs of their specific build when making a decision.

User Experience and Aesthetics

User experience and aesthetics can influence purchasing decisions. The AXP90 X53's low-profile design makes it less visually intrusive, appealing to users who want a cleaner look in compact builds. In contrast, the Peerless Assassin 120 SE Black features an attractive black finish with a modern design that stands out in any build. The dual fans not only enhance its cooling performance but also add to its visual appeal, making it a popular choice for gamers and PC enthusiasts alike.

Which should you buy?

Deciding between the Thermalright AXP90 X53 and the Thermalright Peerless Assassin 120 SE Black ultimately depends on your specific needs. If you are building a compact ITX system and require a low-profile cooler, the AXP90 X53 is an excellent choice due to its slim design and adequate cooling performance. However, if you are looking for superior cooling capabilities and don’t mind a larger cooler, the Peerless Assassin 120 SE Black with its dual fans is the better option, providing more effective heat dissipation. Both coolers offer good compatibility and installation processes, but the choice will come down to your build requirements and personal preferences.
