Dimension comparison
Design and Build Quality
The Thermalright AXP90 X36 is designed to be ultra-compact with a total height of just 36mm, making it ideal for small form factor builds. In contrast, the Thermalright AXP90 X47 offers a slightly taller profile at 47mm, providing a balance between size and enhanced cooling capabilities. Both coolers feature an all-metal platform and back plate fastener, ensuring durability and stability within your computer case.
The AXP90 X36's compact design is beneficial for ITX systems where space is at a premium, while the AXP90 X47, despite its increased height, remains a low-profile option suitable for compact builds. The premium build quality of both units ensures they can withstand the rigors of high-performance computing.
Cooling Performance
Cooling performance is a crucial aspect when choosing a CPU cooler. The AXP90 X36 features four 6mm heat pipes that provide effective thermal transfer, while the AXP90 X47 also has four heat pipes, but its larger 92mm PWM fan enhances airflow and cooling efficiency. The AXP90 X36 operates at a noise level of 22.4 DBA, ensuring quiet operation during intense sessions, while the AXP90 X47 promises a similar noise level of 22.4 dB(A).
The AXP90 X47's increased size allows for improved heat dissipation, making it a better choice for users who demand high performance from their CPUs. Both coolers are compatible with a range of Intel and AMD sockets, making them versatile options for various builds.
Price Comparison
The AXP90 X36 is priced at $20.39, making it about 40% cheaper than the AXP90 X47, which retails for $33.99. This significant price difference may appeal to budget-conscious builders who still want reliable cooling without breaking the bank.
However, the AXP90 X47's higher price may be justified for those looking for superior cooling performance and efficiency. Investing in the AXP90 X47 could be worthwhile for users who plan to overclock their CPUs or require more robust cooling solutions.
Compatibility
Both coolers are designed to support a variety of Intel and AMD CPU sockets, including the latest LGA 1700 and AM5. The AXP90 X36 is compatible with Intel's LGA1150, 1151, 1200, and AMD's AM4 and AM5 sockets. Similarly, the AXP90 X47 also supports the same range of sockets, ensuring it can fit into most modern ITX builds.
This compatibility makes both options appealing for users looking to upgrade their cooling solution without having to change their entire setup. The AXP90 X47's slightly more advanced design may provide better cooling for users who plan on using higher wattage CPUs.
Noise Levels
Both the AXP90 X36 and AXP90 X47 operate quietly, with noise levels measured at 22.4 dBA and 22.4 dB(A) respectively. This makes them suitable for environments where noise is a concern, such as home offices or gaming setups.
While both coolers aim for silent operation, the AXP90 X47's larger fan might provide more efficient cooling at similar noise levels. Users who prioritize a quiet system while also demanding maximum performance may find the AXP90 X47 a more suitable choice.
