As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You might be looking for thermalright thermalrlght axp90 x53 full alternatives because your case has different clearance limits or you prefer a specific aesthetic. The original Thermalright AXP90 X53 Full offers a 53mm height with pure copper heat pipes and AM5 support. It uses a 92mm fan running at 2700 RPM for solid airflow. However, you may need a lower profile to fit taller RAM sticks or a different color to match your build. Some users also prefer the compactness of a 36mm cooler or the mid-range 47mm option. These alternatives were chosen because their specifications overlap with the original in key areas like socket compatibility and fan size. You can find models that support AM4, AM5, and LGA 1700 sockets. The list includes options with varying heights to suit different ITX case constraints. You can select a cooler that balances height, material, and visual style. This guide helps you find a replacement that fits your physical space and thermal needs without sacrificing compatibility. We focus on the specs that matter for your build.
Our top pick: Thermalright 53mm Full Copper ITX Cooler.
How each alternative compares
Thermalright 47mm Low-Profile CPU Cooler
The Thermalright AXP90 X47 reduces height to 47mm, giving you 6mm of extra clearance compared to the 53mm original. This extra space helps if your RAM sticks are tall. It keeps the 92mm fan and similar socket support for AM4 and AM5. You lose some vertical fin surface area with the lower profile. This model suits ITX cases where RAM clearance is tighter than CPU height. It is a practical swap if you need to clear memory modules without changing your fan size or socket compatibility. The weight is slightly lower at 1.04 pounds.
Thermalright AXP90 Copper Low-Profile Cooler
This option is essentially the same 53mm cooler but listed with specific model details like the D6 designation. It maintains the full copper construction and 92mm fan setup of the original. The primary difference is the specific variant or color option, often white or black. If you want the exact same cooling performance but a different aesthetic for your case, this is the direct match. It supports the same AM4, AM5, and Intel sockets. There is no change in height or airflow specs. It is for users who want the original performance but prefer a specific finish or minor model variation.
Thermalright 47mm Low-Profile CPU Cooler
The AXP90 X47 Black also stands at 47mm, offering 6mm less height than the 53mm original. It adds LGA 1851 support, which the original data does not explicitly list. The black finish provides a different look. You trade 6mm of height for potentially newer socket support. The fan size remains 92mm. This choice is for builders who need the extra RAM clearance and want a black aesthetic. It also includes LGA 1851 compatibility. The weight is 1.1 pounds. It is a solid mid-height option if you prioritize socket versatility and color over the maximum 53mm height of the original.
Thermalright AXP90 36mm Low-Profile Cooler
The AXP90 X36 drops the height significantly to 36mm. You gain 17mm of extra clearance compared to the 53mm original. This is for extreme compact builds where RAM or case height is very limited. You sacrifice cooling capacity for this space savings. It supports LGA 1851 and AM5. The fan is still 92mm. This model is for users who cannot fit the 53mm cooler at all. It is the right pick when space is the only constraint. The weight is 14.4 ounces. Choose this if you have low TDP CPUs and need the lowest possible profile.
Thermalright AXP90-X47 Full Copper Cooler
The AXP90 X47 Full Copper is another 47mm option. It matches the original in using pure copper heat pipes. It offers 6mm less height, aiding RAM clearance. It supports AM4, AM5, and LGA 1200 sockets. The weight is 1 pound. This model is for builders who want the copper construction of the original but need the shorter 47mm profile. It is a practical fit for ITX cases with moderate height limits. The 92mm fan remains standard. It is a reliable choice if you need copper performance but have tighter vertical constraints than the 53mm original allows.
Thermalright AXP90 X36 Black Low Profile Cooler
The AXP90 X36 Black Low Profile is a 36mm cooler. It is 17mm shorter than the original 53mm model. This provides significant clearance for RAM or low-profile cases. It features a black finish. It supports AM4, AM5, and LGA 1200 sockets. The weight is 1 pound. You give up cooling potential for extreme compactness. This is for low TDP CPUs in very tight ITX builds. It is the best choice if you cannot fit the 53mm cooler. The 92mm fan is included. Choose this when space is more critical than raw cooling power.

Frequently asked questions
Can I use a 92mm fan with these Thermalright alternatives?
Yes. All listed models, including the AXP90 X53 Full, X47, and X36, are designed to work with a 92mm fan. This fan size is standard for this line of low-profile coolers. It allows for good airflow while maintaining a compact profile suitable for small ITX cases.
Do these coolers support the AM5 socket?
Most options support AM5. The AXP90 X53 Full, X47, and X36 models list AM5 compatibility in their specifications. This makes them suitable for newer AMD processors. Always verify the specific model's socket list before purchasing to ensure it matches your motherboard.
Which option is best for cases with only 36mm clearance?
The AXP90 X36 is the correct choice for 36mm clearance. It is an ultra-slim low-profile cooler designed for extreme compactness. While it sacrifices some cooling potential compared to taller models, it fits where larger coolers cannot. It is ideal for low TDP CPUs in tight spaces.
Are there black versions of the AXP90 coolers available?
Yes. The AXP90 X47 and AXP90 X36 are available in black. These models offer the same cooling performance as their silver or grey counterparts but provide a different aesthetic. They are suitable for builders who prefer a monochromatic or dark theme for their ITX build.
How much height do I save with the AXP90 X47?
You save 6mm of height compared to the 53mm model. The AXP90 X47 stands at 47mm tall. This extra clearance can help accommodate taller RAM sticks. It offers a balanced profile for ITX cases that have moderate height restrictions.
Do these coolers use copper heat pipes?
Several models use pure copper. The AXP90 X53 Full and the AXP90 X47 Full are explicitly noted for their copper construction. This material helps with heat dissipation. Other models in the lineup may use different materials, so check the specific product attributes for details on the heatsink composition.
Is the AXP90 X53 Full compatible with LGA 1700?
The provided data lists LGA 1200, LGA 1150, and LGA 1151 for the AXP90 X53 Full. It does not explicitly list LGA 1700 in the attributes. However, other models like the X47 Full explicitly mention compatibility with newer sockets. Verify the specific socket list for your motherboard before buying.
What is the weight of the AXP90 X36?
The AXP90 X36 weighs 14.4 ounces. This is lighter than the 47mm and 53mm models, which weigh around 1 pound. The reduced weight reflects its smaller size and lower profile. It is a practical choice for builds where every ounce matters in a small case.
