Thermalright AXP90-X53 Low Profile ITX Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
Finding the right thermalright axp90 x53 low profile itx alternatives depends on your chassis clearance and cooling targets. The Thermalright AXP90-X53 handles tight layouts well with its 53mm total height, pure copper base, and four 6mm heat pipes. Its 92mm PWM fan delivers up to 42.58 CFM of airflow at 2700 RPM while maintaining a 22.4 dBA noise rating. This setup cools modern Intel and AMD sockets without creating memory clearance problems.
You might need an alternative if your case demands even lower clearance than 53mm. Extremely small Mini-ITX cases often require 47mm, 36mm, or even 26.9mm profiles to prevent side-panel collision. Alternatively, you may want an all-copper fin array for different thermal characteristics, a different brand, or a heatsink tailored strictly to 35W processors. These 6 alternatives were chosen because their specifications overlap directly with the original cooler, providing compact footprints, slim fan pairings, and low-profile mounting for small-form-factor motherboards.

Comparing AXP90-X53 to Low-Profile Alternatives
Thermalright 47mm Low-Profile CPU Cooler
The Thermalright AXP90-X47 Black reduces total cooler height from 53mm down to 47mm. This 6mm reduction gives you necessary clearance in compact Mini-ITX cases where the AXP90-X53 is too tall. It features an all-black finish and retains four heat pipes alongside a 92mm fan. Both models weigh 1.1 pounds and support AMD AM4, AM5, and Intel LGA 1851, 1200, 1150, and 1151 sockets. However, the shorter 47mm profile reduces total heatsink volume compared to the 53mm stack of the original. Choose this model if your chassis strictly limits cooler clearance to under 50mm and you prefer a black aesthetic.
Thermalright AXP90 36mm Low-Profile Cooler
The Thermalright AXP90-X36 drops total cooler height to 36mm, shaving 17mm off the 53mm AXP90-X53. At 14.4 ounces, it is also lighter than the 1.1-pound original. This ultra-slim heatsink preserves four heat pipes and fits tightly confined enclosures that cannot house taller coolers. It shares socket coverage with the original across Intel LGA 1851, 1200, 1150, 1151, and AMD AM4 and AM5. To reach this 36mm profile, you trade away substantial fin surface area compared to the 53mm aluminum radiator. You should pick the AXP90-X36 if you are assembling an ultra-compact Mini-ITX build with severe height restrictions that rule out 47mm and 53mm coolers.
Akasa 26.9mm Low-Profile LGA 1700 Cooler
The Akasa AK-CC6601EP01 stands just 26.9mm tall and weighs only 5.86 ounces, cutting vertical height nearly in half compared to the 53mm, 1.1-pound AXP90-X53. It features an aluminum heatsink and integrated fan designed specifically for tight chassis spaces. However, you give up significant capability compared to the Thermalright cooler. It lacks pure copper heat pipes and a copper base, restricts power consumption strictly to 35W envelopes, and supports only Intel LGA 1700. The AXP90-X53 supports AMD AM4 and AM5 alongside multiple Intel generations. Pick the Akasa cooler if you are building an ultra-slim Mini-ITX system with a 35W Intel processor that cannot accommodate a 53mm heatsink.
Thermalright 47mm Low-Profile CPU Cooler
This Thermalright AXP90-X47 model reduces installation height to 47mm, saving 6mm compared to the 53mm AXP90-X53. At 1.04 pounds, it is slightly lighter than the 1.1-pound original while retaining four heat pipes and a 92mm fan running at 2700 RPM. This configuration provides identical fan speed and airflow mechanics in a lower vertical profile. In exchange for the 47mm clearance, you receive less fin surface area than the 53mm stack offers. Its listed compatibility covers AMD AM4, AM5, and Intel LGA 1200, 1150, and 1151. Pick this silver version if your ITX enclosure requires sub-50mm clearance and you want four-pipe cooling with matching fan specifications.
Thermalright AXP90-X47 Full Copper Cooler
The AXP90-X47 Full Copper swaps the aluminum fin array of the AXP90-X53 for an all-copper construction. Copper offers higher thermal conductivity than aluminum. It also lowers overall cooler height from 53mm down to 47mm, saving 6mm for tight Small Form Factor layouts. It weighs 1 pound, compared to 1.1 pounds for the original model. You sacrifice vertical heatsink height, giving up the taller fin surface area present on the 53mm cooler. Socket support includes AMD AM4 and AM5, along with Intel LGA 1200, 1150, and 1151. Choose this alternative if your Mini-ITX chassis demands a 47mm clearance limit and you want the thermal conductivity of a complete copper heatsink.
Thermalright AXP90-X47 Black Low-Profile Cooler
The Thermalright AXP90-X47 Black provides a 47mm total profile, reducing cooler height by 6mm compared to the 53mm AXP90-X53. It weighs 1 pound, making it slightly lighter than the 1.1-pound original. This alternative includes four copper heat pipes, an included 92mm PWM fan, and an all-black aesthetic. By choosing the shorter 47mm heatsink, you give up the greater fin area provided by the 53mm stack of the original. Its listed socket support spans AMD AM4 and AM5, alongside Intel LGA 1200, 1150, and 1151. Pick this cooler if your Mini-ITX build has strict height restrictions below 50mm and you require an all-black design with four copper heat pipes.

Frequently asked questions
Which low-profile cooler alternative is best if your ITX case has under 40mm of clearance?
The Thermalright AXP90-X36 is your best alternative for clearance under 40mm. It stands 36mm tall while keeping four heatpipes and an included fan. This model weighs 14.4 ounces and supports sockets such as AM4, AM5, LGA 1851, LGA 1200, and LGA 115x. It gives you dependable cooling when cases cannot accommodate standard 47mm or 53mm coolers.
Can you mount these AXP90-X53 alternative coolers on newer Intel LGA 1851 sockets?
Yes, select alternatives like the Thermalright AXP90-X36 and AXP90-X47 Black list direct compatibility with Intel LGA 1851. Both models also support Intel LGA 1200, LGA 1150, LGA 1151, and AMD AM4 and AM5 platforms. Always verify the exact socket hardware included with your chosen model version before installing it on your Mini-ITX motherboard.
How does a full copper low-profile cooler differ from standard aluminum-fin models?
Full copper models like the Thermalright AXP90-X47 Full Copper use copper fins instead of aluminum to deliver higher thermal conductivity. Copper transfers heat across the fin stack faster, though it results in a heavier assembly. At 47mm tall, it fits compact ITX cases that support 1-pound coolers on AM4, AM5, or LGA 1200 and LGA 115x sockets.
What is the lowest profile alternative available for an Intel LGA 1700 Mini-ITX build?
The Akasa AK-CC6601EP01 is the lowest profile option listed, measuring just 26.9mm in height. This aluminum cooler weighs 5.86 ounces and is designed specifically for low-draw LGA 1700 processors within a 35W power envelope. It maximizes vertical clearance in ultra-slim chassis designs where standard 47mm or 53mm heatsinks are too tall to fit.
What fan speed do Thermalright 47mm low-profile coolers run at?
The Thermalright 47mm low-profile cooler features a 92mm fan operating at speeds up to 2700 RPM. This high-speed airflow moves air directly through four heat pipes to manage thermal output within tight ITX enclosures. The 47mm height helps you maintain necessary space between the fan intake and your case panel for improved air intake.
How do you know whether to pick a 47mm or 53mm ITX cooler?
You should measure the vertical distance between your CPU socket and the case side panel before choosing. The Thermalright AXP90-X53 requires 53mm of vertical clearance, while 47mm alternatives like the AXP90-X47 provide an extra 6mm of breathing room. Leaving adequate space above the 92mm fan prevents intake restriction and turbulence against side panels or mesh covers.
Do low-profile Mini-ITX coolers support both AMD AM4 and AM5 sockets?
Yes, multiple alternatives in this guide support both AMD AM4 and AM5 motherboard sockets. Models like the Thermalright AXP90-X36 and the standard or full copper AXP90-X47 list compatibility for both platforms alongside older Intel sockets. Because AM4 and AM5 share identical mounting dimensions for many coolers, you can transition between these AMD platforms easily.
