Dimension comparison
Overview of the Thermalright AXP90 X36 and AXP90 X53
The Thermalright AXP90 X36 is priced at $20.39, while the AXP90 X53 is about 2% cheaper at $19.39. Both are designed as low-profile CPU coolers suitable for compact ITX builds, but they differ in height and some performance features. The AXP90 X36 has a height of 36mm, making it ideal for extremely tight spaces, while the AXP90 X53 stands taller at 53mm but may offer improved cooling performance due to its design and fan specifications.
Cooling Performance
Cooling performance is a crucial factor when selecting a CPU cooler. The AXP90 X36 features a 4×6mm AGHP heat pipe design with noise levels capped at 22.4 DBA. In contrast, the AXP90 X53 also utilizes 4 heat pipes but is geared towards a TDP (Thermal Design Power) of up to 150W, suggesting it may handle higher heat loads effectively. The AXP90 X53’s 92mm high-performance fan operates at a maximum speed of 2700 RPM, providing a significant air volume of 42.58 CFM, which may result in superior cooling performance compared to the AXP90 X36.
Build Quality and Design
Both coolers are made with premium materials, ensuring durability and effective heat dissipation. The AXP90 X36 features a nickel plating process, enhancing its corrosion resistance, while the AXP90 X53 utilizes a pure copper base along with 4 copper heat pipes. This design not only improves the cooling efficacy but also reduces the risk of thermal degradation over time. Additionally, the AXP90 X36's compact 36mm height allows it to fit into smaller cases without compromising on quality, making it particularly appealing for minimalist builds.
Compatibility with CPU Sockets
When it comes to compatibility, both coolers support a wide range of CPU sockets. The AXP90 X36 is compatible with Intel sockets 115X/1200 and AMD's AM4 and AM5. The AXP90 X53 offers broader compatibility, supporting Intel sockets 1150/1151/1155/1156/1200/1700/1851 and AMD AM4/AM5, making it suitable for a wider variety of systems. This versatility in socket compatibility is critical for users looking to upgrade or switch platforms in the future.
Noise Levels
Noise levels can significantly affect the user experience, especially in quiet computing environments. Both the AXP90 X36 and AXP90 X53 operate at a maximum noise level of 22.4 DBA, which is considered quite silent. However, the AXP90 X53’s fan is designed for automatic temperature control, which might allow it to operate more quietly under low loads compared to the AXP90 X36, depending on the specific usage scenario. This may make the AXP90 X53 a more attractive option for users prioritizing silence.
Installation Process
Ease of installation is another factor to consider when choosing a CPU cooler. The AXP90 X36 features an all-metal platform with a back plate fastener, while the AXP90 X53 comes with corresponding metal mounting fasteners for both Intel and AMD platforms. The AXP90 X53 also provides an installation video, which could facilitate a smoother installation process for users who may be less experienced. This attention to user-friendliness in the AXP90 X53 may make it preferable for those who value a straightforward setup.
Price Comparison
In terms of pricing, the AXP90 X36 is available for $20.39, while the AXP90 X53 is more budget-friendly at $19.39. This represents a difference of about $1, making the AXP90 X53 roughly 5% less expensive than its counterpart. For budget-conscious consumers or those looking to optimize performance-to-cost ratios, the AXP90 X53 offers a compelling option without sacrificing quality or performance.
Which should you buy?
Choosing between the Thermalright AXP90 X36 and the AXP90 X53 depends on your specific needs and system requirements. If you need a cooler for an extremely compact build, the AXP90 X36, with its lower height, may be the better choice. However, for users looking for enhanced cooling performance and broader compatibility, the AXP90 X53 stands out as a more robust option at a slightly lower price. Ultimately, both coolers provide excellent performance for their size and price, making either a solid choice for ITX builds.
