Introduction to CPU Coolers
When it comes to cooling your CPU, selecting the right cooler can significantly impact performance and longevity. In this comparison, we will explore two notable options: the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler and the Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler. Both products come from the reputable brand Thermalright, known for their innovative cooling solutions.
Design and Build Quality
The Thermalright Peerless Assassin 120 features a dual tower design with dual fans, providing excellent heat dissipation capabilities. It measures 125x138x162mm and incorporates a magnetic top cover, enhancing its aesthetic appeal. This cooler is equipped with six pure copper heat pipes that ensure efficient thermal conductivity. On the other hand, the AXP90 X53 has a compact profile, standing only 53mm tall, making it ideal for small form factor builds. It utilises a 92mm slim PWM fan and incorporates the latest AGHP technology, enhancing heat transfer efficiency. The build quality of both coolers reflects Thermalright's commitment to durability and performance.
Cooling Performance
Cooling performance is a critical factor to consider when choosing a CPU cooler. The Thermalright Peerless Assassin 120 operates with a fan speed of 1850 RPM and an air volume of 88.89 CFM, which ensures effective heat dissipation. The combination of dual fans and high wind pressure (2.21mm H2O) contributes to its superior cooling performance. In contrast, the AXP90 X53 features a single 92mm fan that can reach speeds of up to 2700 RPM. Although it has a smaller airflow capacity, its advanced AGHP technology allows it to maintain excellent cooling efficiency, especially in compact cases.
Noise Levels
Noise levels are an important consideration for users who prioritise a quiet computing environment. The Peerless Assassin 120 operates at a noise level of ≤25.6 dB (A), making it relatively quiet during operation. This balance between performance and noise is appealing for gamers and professionals alike. Conversely, while the AXP90 X53 does not specify a noise level, the design of its S-FDB bearings aims to reduce noise and enhance longevity. Users can expect quieter operation from the AXP90, especially given its smaller size and single fan configuration.
Installation Process
Both coolers offer straightforward installation processes, but their compatibility and design approach differ. The Thermalright Peerless Assassin 120 includes SS2 clips that ensure compatibility with various CPU models, making installation easier for users. Its design allows for convenient maintenance and upgrades. The AXP90 X53 also boasts broad compatibility with multiple CPU slots, including Intel LGA1700 and AMD AM4/AM5. However, users may need to adapt the backplane installation depending on their motherboard setup, which could complicate the process slightly for some users.
Aesthetics and Lighting
Aesthetically, the Peerless Assassin 120 stands out with its ARGB lighting effects, allowing users to customise the colour through their motherboard's software. This feature not only enhances the visual appeal of a build but also allows for synchronisation with other RGB components. In contrast, the AXP90 X53 has a more utilitarian design focused on performance rather than flashy aesthetics. While it may not offer RGB lighting, its sleek, low-profile appearance is ideal for minimalist builds, particularly in compact cases.
Price and Value
Price is always a significant factor when choosing components, and both coolers are competitively priced. The Thermalright Peerless Assassin 120 is available for C$52.62, while the AXP90 X53 is slightly more affordable at C$45.99. Despite the small price difference, the Peerless Assassin 120 offers dual fans and higher airflow, which may justify the additional cost for users needing enhanced cooling performance. However, for those with space constraints or budget considerations, the AXP90 X53 provides excellent value without sacrificing cooling efficiency.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler and the Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler largely depends on your specific needs and use case. If you prioritise superior cooling performance and aesthetic customization, the Peerless Assassin 120 is the better option. However, if you require a compact solution for a smaller build without compromising on cooling capability, the AXP90 X53 stands out as a fantastic choice. Both coolers reflect Thermalright's commitment to quality and performance, ensuring you cannot go wrong with either selection.
