Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler - Compact

In this review of the Thermalright AXP90 X53, the bottom line is simple: this is a purpose-built low profile cooler for small form factor builds that need genuine thermal performance without a tall tower. The AXP90 X53 stands out because its pure copper radiator and upgraded AGHP heat pipe design deliver better heat transfer than typical slim coolers, while the included 92mm slim PWM fan spins up to 2700RPM for peak airflow. For builders who prioritize thermal headroom in Mini-ITX systems, this cooler is a practical balance of size, cooling, and durable construction.

Key Features

• Pure copper radiator: The all-copper heatsink increases oxidation resistance and improves heat conduction for sustained CPU loads.
• AGHP 4th generation heat pipes: Four 6mm pipes with soldered fins reduce inverse gravity effects and double heat transfer efficiency compared with basic designs.
• Low 53mm profile: A 53mm overall height makes this cooler compatible with many small motherboards and tight ITX cases.
• 92mm slim PWM fan: The TL-9015R fan delivers up to 42.58 CFM at 2700RPM and is PWM-controlled for flexible cooling vs noise tradeoffs.
• S-FDB bearing: The upgraded STABLY-FDB V2 bearing improves stability and extends fan life up to about 20,000 hours.
• Included thermal paste and mounting hardware: The package includes thermal compound and multiple screws/backplate options for Intel and AMD sockets.

Who It's For

The Thermalright AXP90 X53 is aimed at Mini-ITX builders and small form factor enthusiasts who need a compact cooler that still handles moderate to heavy CPU loads. It is especially suited to systems where case clearance prohibits taller coolers but where users want better-than-stock cooling and the durability of a copper radiator.

Those who should look elsewhere include extreme overclockers or anyone running the hottest, highest-wattage CPUs in cramped airflow environments; a larger tower or AIO will offer more thermal headroom. Also, if absolute silence at idle is the primary goal, lower-RPM or larger, slower fans may be preferable.

Pros & Cons

Pros

• Excellent thermal material choice with a pure copper radiator for improved heat transfer and longevity.
• Compact 53mm height fits many ITX motherboards and small cases where larger coolers cannot.
• Strong airflow from the 92mm 2700RPM PWM fan for its size, with a stable S-FDB bearing that boosts durability.
• Includes thermal paste and versatile mounting hardware for Intel and AMD platforms.

Cons

• Mounting design receives mixed feedback and may require patience or alternate screw orientations on some motherboards.
• At high RPM the fan can be noticeable; it is not the quietest option available for silent-focused builds.

Our Verdict

The Thermalright AXP90 X53 is a sensible choice for Mini-ITX builders who need a low profile cooler that does not compromise on materials or thermal design. Its pure copper radiator, upgraded AGHP heat pipes and a high-speed 92mm PWM fan deliver reliable cooling and good value for compact systems; just be prepared for a slightly involved mounting process on some motherboards and some audible fan noise at maximum speed.

Frequently Asked Questions

Will this fit my Mini-ITX case?
Measure available CPU cooler clearance - the AXP90 X53 is 53mm tall, so it fits most ITX cases designed for low profile coolers.

Does it support modern Intel and AMD sockets?
The kit includes mounting hardware for Intel LGA1150/1151/1200/1700 and AMD AM4/AM5, with alternate screw options if the backplate interferes.

Is the included fan quiet?
The slim 92mm fan is relatively quiet at moderate speeds, but at its 2700RPM peak it can be noticeably louder than larger slow-spinning fans.
