Thermalright 47mm Low-Profile CPU Cooler Alternatives: 6 Similar Picks Compared

How These Low-Profile Coolers Differ

Thermalright AXP90 Copper Low-Profile Cooler

The Thermalright AXP90 X53 adds six millimeters of height, reaching 53mm total. This extra space allows for more robust thermal performance compared to the 47mm baseline. You gain cooling headroom if your case permits the larger footprint. The unit retains the 92mm fan size and similar socket compatibility for AM4, AM5, and Intel LGA platforms. It uses copper materials for better heat conduction. This option suits builders who need slightly more capacity than the X47 provides but still require a low-profile form factor. It is a practical upgrade for cases that can accommodate the additional height without restricting RAM clearance.

Thermalright 53mm Full Copper ITX Cooler

This 53mm full copper cooler prioritizes material quality over minimal height. It matches the X53 in dimensions but emphasizes a copper construction for improved thermal transfer. The 92mm fan ensures consistent airflow similar to the original X47. Socket support includes AM4, AM5, and various Intel LGA types. You choose this model if you have 53mm clearance and want maximum cooling efficiency from a low-profile design. It sacrifices the ultra-compact 47mm profile for better heat dissipation. This makes it ideal for ITX builds where thermal performance is critical and case dimensions allow for the taller cooler. It offers a reliable balance between size and cooling power.

Thermalright 47mm Low-Profile CPU Cooler

The AXP90 X47 Black variant maintains the 47mm height but introduces a black finish and supports the newer LGA 1851 socket. This expands compatibility to the latest Intel processors without changing the physical footprint. The weight is slightly higher at 1.1 pounds compared to the silver version. You should pick this if you need LGA 1851 support or prefer a darker aesthetic. It retains the same 92mm fan and low-profile dimensions as the original. The additional socket support makes it future-proof for newer Intel platforms. It is a direct alternative for users who want the same compact size but need broader compatibility or a different color scheme.

Thermalright AXP90 36mm Low-Profile Cooler

The AXP90 X36 reduces height significantly to just 36mm, making it suitable for ultra-compact cases. You lose some cooling capacity compared to the 47mm X47, but gain the ability to fit in spaces under 40mm. It supports AM4, AM5, and Intel LGA sockets, including LGA 1851. The 92mm fan remains consistent, ensuring familiar airflow characteristics. This model is for builders who must prioritize case closure and RAM clearance over maximum thermal performance. It sacrifices six millimeters of height for extreme compactness. If your case has strict height limits, this is the practical choice. It offers essential cooling for low-TDP processors in tight ITX builds.

Thermalright AXP90-X47 Full Copper Cooler

The AXP90-X47 Full Copper version keeps the 47mm height but uses copper heat pipes for superior heat transfer. This material change improves cooling efficiency over the aluminum-based original. It maintains the same 92mm fan and socket compatibility for AM4, AM5, and Intel LGA platforms. The weight is similar at one pound. You should choose this if you want better thermal performance within the same 47mm constraint. It is ideal for LGA 1700 and AM4 builds where space is tight but cooling needs are high. The copper construction offers a practical upgrade without increasing the physical size. It provides reliable cooling for users who need the lowest profile with enhanced material quality.

Thermalright AXP90 X36 Black Low Profile Cooler

The AXP90 X36 Black variant offers the same 36mm height as the standard X36 but in a black finish. It supports AM4, AM5, and Intel LGA sockets, including LGA 1200 and 1151. The weight is one pound, similar to other models in this range. You pick this if you need ultra-compact cooling for cases with tall RAM modules or strict height limits. It sacrifices thermal headroom for minimal height. The black color provides a different aesthetic option. It is best for low-TDP processors in small form factor builds. This model ensures your case closes properly while providing adequate cooling for less demanding systems. It is a practical choice for extreme compactness with a preferred color.
