Overview of the Thermalright AXP90 X36 and Peerless Assassin 120

The Thermalright AXP90 X36 Low Profile ITX CPU Cooler is priced at $20.39, making it about 65% cheaper than the Thermalright Peerless Assassin 120 Vision MAX ARGB Black CPU Air Cooler, which costs $57.69. While the AXP90 X36 is tailored for compact builds with its low-profile design, the Peerless Assassin offers a more robust cooling solution with advanced features and higher performance ratings.

Design and Build Quality

The AXP90 X36 features a compact design with a total height of just 36mm, making it ideal for small form factor builds. It employs an all-metal platform with a nickel plating process that enhances corrosion resistance and durability. In contrast, the Peerless Assassin stands significantly taller at 164mm and incorporates a dual-tower design, allowing for superior cooling performance. Its construction includes six pure copper heat pipes and a magnetically attached top cover with an IPS LCD screen, enhancing both aesthetics and functionality.

Cooling Performance

When it comes to cooling performance, the Peerless Assassin clearly outshines the AXP90 X36. The Peerless Assassin operates at a fan speed of 2150 RPM, providing an airflow of 69 CFM, which is crucial for dissipating heat effectively in high-performance systems. Meanwhile, the AXP90 X36 operates at a maximum noise level of just 22.4 dBA, but its cooling capacity is limited compared to the more powerful setup of the Peerless Assassin.

Compatibility

The AXP90 X36 is designed for compatibility with a variety of CPU sockets including AMD AM4/AM5 and Intel LGA1150/1151/1200/1700/1851, making it a versatile choice for ITX builds. Conversely, the Peerless Assassin also supports a wide range of sockets but is tailored more for mainstream ATX cases given its larger dimensions. This makes the AXP90 X36 a better fit for compact cases, while the Peerless Assassin is better suited for high-performance setups.

Noise Levels

The AXP90 X36 offers a quieter operation with a maximum noise level of 22.4 dBA, making it an excellent choice for users seeking a silent computing experience. The Peerless Assassin, although slightly noisier with an operating noise level of up to 27 dBA, compensates for this with its superior cooling performance. Users who prioritize silence may prefer the AXP90, while those focused on cooling efficiency may lean towards the Peerless Assassin.

Added Features

One of the standout features of the Peerless Assassin is its 5-inch IPS LCD screen that allows for real-time monitoring of system parameters. This feature, combined with the TRCC control software for custom backgrounds, elevates the user experience by providing valuable information at a glance. In contrast, the AXP90 X36, while robust in its cooling capabilities, lacks such advanced features, appealing primarily to those who need a basic yet effective cooling solution.

Price Consideration

The AXP90 X36 is not only cheaper at $20.39, but it also offers a compelling value for budget-conscious consumers. It is about 65% less expensive than the Peerless Assassin, which is priced at $57.69. While the price difference is significant, it reflects the enhanced performance and features of the Peerless Assassin, making it a more suitable option for gamers and content creators who need reliable cooling under heavy loads.

Which should you buy?

Choosing between the Thermalright AXP90 X36 and the Peerless Assassin 120 comes down to your specific needs. If you're looking for a cost-effective, low-profile cooler ideal for compact builds, the AXP90 X36 is the clear choice. However, if you require superior cooling performance and advanced features, the Peerless Assassin 120 is worth the extra investment. Ultimately, your decision should be based on your system's requirements and your budget preferences.
