Overview of the Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler
The Thermalright AXP90-X53 White Low Profile ITX CPU Air Cooler offers a compact design ideal for small form factor builds. At a price of $19.39, it is about 2% cheaper than the Assassin King 120 SE. This cooler stands at just 53mm tall, making it perfect for ITX motherboards and small chassis. It employs a 92mm PWM fan that can reach speeds of up to 2700 RPM, providing impressive cooling while maintaining a low noise level of 22.4 dB(A). With four heat pipes and a pure copper base, it effectively manages heat dissipation in constrained spaces.
Cooling Performance Comparison
The Thermalright Assassin King 120 SE is designed to handle enhanced cooling needs, featuring five heat pipes and an airflow of 66.17 CFM at maximum fan speed. This cooler is suitable for CPUs with a higher thermal design power (TDP), making it ideal for overclocking scenarios. In contrast, the AXP90-X53, while smaller, still packs a punch with its four heat pipes and a maximum airflow of 42.58 CFM. However, it is rated for CPUs with a TDP of up to 150W, which may limit its efficacy in high-performance setups compared to the Assassin King.
Size and Compatibility
When it comes to size, the Thermalright AXP90-X53 is significantly more compact, standing at just 53mm tall compared to the 148mm height of the Assassin King 120 SE. This low profile allows it to fit in smaller cases without interfering with memory clearance, making it a prime choice for ITX builds. Both coolers are compatible with a wide range of CPU sockets, including AMD AM4/AM5 and Intel LGA 1700/1150/1151/1200/1851, which ensures that users can install them on various platforms without issue.
Noise Levels and Operation
Noise levels are crucial for many users, particularly those building quiet PCs. The Assassin King operates at a maximum noise level of 25.6 dB(A), while the AXP90-X53 is quieter, operating at just 22.4 dB(A). This means that while the Assassin King may provide better cooling performance, the AXP90-X53 will likely be the preferred choice for users prioritizing silent operation. Both products utilize PWM technology to adjust fan speeds based on CPU temperature, optimizing performance while minimizing noise.
Aesthetic Appeal
For users who appreciate visual customization, the Thermalright Assassin King 120 SE comes with colorful ARGB lighting effects, adding a vibrant touch to any build. The sleek white design complements modern gaming setups. In contrast, the AXP90-X53 presents a more understated look, focusing on functionality over aesthetics. While it may lack the RGB flair, its minimalist design can appeal to users who prefer a clean and professional appearance in their builds.
Price Comparison
The Thermalright Assassin King 120 SE is priced at $19.82, while the AXP90-X53 is slightly more affordable at $19.39.
