Thermalright AXP90-X47 Low Profile ITX CPU Cooler - 47mm Height

In this review of the Thermalright AXP90-X47, the bottom line is simple: this is a purpose-built low profile cooler for small ITX builds that need capable cooling without sacrificing clearance. It delivers notable cooling capacity in a very compact 47mm package, pairing a pure copper radiator and heat pipes with a slim 92mm PWM fan. For builders running HTPCs, compact gaming rigs or SFF workstations where RAM and chassis clearance matter, the AXP90-X47 offers quiet, effective thermal control in a format that fits where most tower coolers cannot.

Key Features

• Pure copper construction: The cooler uses a pure copper base, fins and heat pipes to improve heat transfer and oxidation resistance for sustained thermal performance.
• 47mm total height: With a full cooler height of just 47mm it fits tight ITX cases and HTPC chassis without interfering with memory modules or other low-profile components.
• 92mm TL-9015R PWM fan: The slim fan provides up to 42.58 CFM at 2700 RPM with automatic PWM control to balance noise and cooling.
• AGHP technique on heat pipes: The 46mm heat pipes use an AGHP process to reduce inverse gravity effects and improve cooling when the orientation of the cooler varies in small cases.
• Broad socket support: Mounting hardware is provided for Intel LGA1700/1851/1150/1151/1155/1156/1200 and AMD AM4/AM5, covering modern and legacy small-form-factor builds.
• Included thermal paste: A tube of thermal paste is supplied to help achieve good contact and initial thermal transfer during installation.

Who It's For

The AXP90-X47 is ideal for users building compact systems where headroom is constrained: HTPCs, Mini-ITX gaming rigs and small workstation boxes that need a quiet cooler without large towers. It suits processors with moderate TDPs in cramped chassis and users who prioritize a low profile and low noise over extreme overclocking.

It is less suitable for enthusiasts chasing maximum overclocking headroom or those who run very high TDP CPUs in small cases; for extreme cooling needs a larger tower or a liquid solution will deliver lower peak temperatures. Also note AMD installations require using the motherboard backplate when present, as the product does not include an AMD backplate.

Pros & Cons

Pros

• Excellent profile for tight builds, fitting 47mm clearance scenarios.
• Solid thermal performance thanks to pure copper base, fins and heat pipes.
• Quiet operation with the TL-9015R PWM fan that balances noise and airflow.
• Wide socket compatibility makes it useful across Intel and AMD small-form-factor systems.

Cons

• Mounting system draws mixed feedback; installation can be fiddly on some motherboards compared with simpler brackets.
• Not aimed at heavy overclocking or very high TDP CPUs where larger coolers perform better.

Our Verdict

The Thermalright AXP90-X47 is a focused solution for compact PC builders who need reliable, quiet cooling in a strict 47mm envelope. It combines good heat dissipation from pure copper construction and a high-performance slim fan to keep mainstream CPUs cool in tight cases. For those with moderate thermal loads, it is a strong value; enthusiasts needing maximum headroom should consider larger options.

Frequently Asked Questions

Will this fit on AM5 motherboards?
Yes, the heatsink supports AM5 and includes the metal mounting fasteners required for AMD platforms, but installation uses the motherboard backplate when present.

How loud is the fan at full speed?
The TL-9015R reaches about 22.4 dB(A) in typical operation, making it noticeably quiet for a 92mm fan at higher RPM.

Can it handle small gaming CPUs?
It handles mainstream gaming CPUs well in compact builds, but very high TDP processors or heavy overclocking will benefit from larger coolers.
