Thermalright AXP90-X53 Full Cooper Low Profile CPU Cooler - 53mm ITX

In this review the Thermalright AXP90-X53 is judged on its fit for compact builds and cooling performance. It is aimed at HTPC and small-form-factor systems where clearance is tight and quiet operation matters. The single biggest reason to buy is its true low profile design paired with a pure copper radiator and a 92mm slim PWM fan that together deliver better-than-expected heat transfer in cramped cases while keeping noise low.

Key Features

• Low profile 53mm height: The total cooler height of 53mm makes it compatible with many ITX and HTPC cases where taller towers cannot be used.
• Pure copper radiator: A pure copper radiator and micro-carved copper base improve oxidation resistance and long-term thermal contact for stable cooling.
• AGHP heat pipe design: Fourth-generation AGHP 4x6mm heat pipes with soldered fins reduce inverse-gravity losses and boost heat transfer efficiency in varied orientations.
• 92mm TL-9015R PWM fan: The slim fan provides up to 42.58 CFM at 2700 RPM with automatic PWM control for a balance of airflow and quiet operation.
• Broad socket support: Mounting fasteners are included for Intel LGA1700/115x/1200/1851 and AMD AM4/AM5 platforms for cross-platform compatibility.
• Included thermal paste: Supplied thermal compound helps establish initial contact and improve heat transfer from the CPU to the copper base.

Who It's For

The AXP90-X53 is best for builders of small-form-factor PCs, HTPCs, and compact gaming rigs who need a genuine low profile cooler that still uses a copper radiator and a 92mm fan for decent thermal performance. It suits users who prioritize clearance and quiet PWM fan control over absolute top-end cooling.

Those who should look elsewhere include overclockers and users of high-TDP chips who need large heatsinks or multiple heat pipes for extreme cooling, as this design favors compact compatibility over maximum heat capacity. Also, buyers uncomfortable with fiddly backplate installation might prefer a simpler mounting system.

Pros & Cons

Pros

• Excellent low profile fit that clears memory and case restrictions in many ITX builds.
• Pure copper base and radiator with micro-carved finish improve thermal contact and durability.
• AGHP soldered fins and heat pipes increase heat transfer efficiency compared with older low-profile coolers.
• Quiet, PWM-controlled 92mm fan provides usable airflow without high noise at typical loads.

Cons

• Mounting can be hit-or-miss: some users report the backplate and screw sequence is fiddly or less intuitive than alternatives.
• Not intended for heavy overclocking or the highest TDP CPUs where larger coolers perform better.

Our Verdict

The Thermalright AXP90-X53 is a practical choice for compact system builders who need a true low profile cooler without sacrificing material quality; its pure copper construction and AGHP heat pipe design deliver reliable cooling for mainstream CPUs and keep noise low. It represents good value for HTPC and ITX use, though anyone seeking extreme thermal headroom or the easiest possible installation should consider larger or more installation-friendly alternatives.

Frequently Asked Questions

Will this fit in most ITX cases?
Yes, the 53mm total height is designed for ITX and HTPC cases but always measure your case clearance before purchase.

Is the fan quiet under load?
The TL-9015R PWM fan is tuned for low noise and will remain relatively quiet at typical loads, though it can reach higher RPMs under heavier sustained loads.

Does it support AM4 and AM5?
Yes, the cooler ships with mounting hardware for AMD AM4 and AM5 and multiple Intel sockets; follow the included instructions for correct backplate orientation.
