Who it fits
Good fit for
You should choose this cooler if you are building an ITX system with limited vertical clearance. The 47mm height allows it to fit under many low-profile cases. It supports Intel LGA 1700, 1200, 1150, 1151, and AMD AM4 sockets. This makes it versatile for older and newer platforms. The pure copper base helps maintain lower temperatures in confined spaces. If your case height is under 50mm, this is a strong option to consider.
Who should skip it
Skip this if you need to cool high-end CPUs that generate significant heat. The small 92mm fan and compact radiator limit total heat dissipation. It is not designed for overclocking or high-wattage processors. You should look elsewhere if you require maximum thermal headroom. The low-profile design sacrifices some cooling potential for size. Users with large cases or standard towers will find better performance in bigger coolers.
Verdict: This cooler is a practical choice for tight ITX builds where height is the primary constraint. It offers solid copper construction and adequate airflow for moderate loads.
Key specs explained for you
Cooler Height 47mm
This measurement defines the total vertical space the cooler occupies. You need to check your case’s CPU cooler height limit to ensure this unit fits. A 47mm profile allows installation in compact ITX cases or behind tall RAM sticks. Compare this value with standard tower coolers, which often exceed 150mm, to understand the significant space savings this low-profile design provides for small builds.
Fan Size 92mm
This indicates the diameter of the included cooling fan. A 92mm fan is smaller than the standard 120mm or 140mm units found in larger coolers. You will notice slightly less airflow capacity, but the smaller size is necessary to maintain the low 47mm height. When shopping, compare this against larger fans to gauge the trade-off between physical compactness and maximum air movement potential.
Heat Pipes 4
This count shows the number of copper heat pipes transferring heat from the base to the fins. Four pipes provide a balanced thermal path for mid-range processors. You benefit from efficient heat spreading across the small radiator surface. Compare this specification with dual-heat-pipe models for entry-level cooling or six-heat-pipe units for high-end chips to determine if the thermal capacity matches your CPU's power requirements.
Socket Compatibility AM4, AM5, LGA 1150/1151/1200/1700
This list defines the CPU mounting points supported by the included bracket. It covers major AMD and Intel platforms, including the latest AM5 and LGA 1700 sockets. You must verify your specific motherboard socket before purchase. Compare this list with your system specifications to ensure physical fitment. Note that older sockets like LGA 1155 are also listed, offering broad backward compatibility for existing builds.
Design and build details
The Thermalright AXP90-X47 uses a full copper construction for its base. This material choice provides excellent thermal conductivity, allowing heat to move quickly from the processor into the cooling system. The listing specifies a pure copper base, which is a standard and effective material for this type of low-profile cooler. You benefit from direct contact with a material that spreads heat efficiently across the four heat pipes integrated into the design.
According to the listing, the unit measures 47mm in total height. The radiator itself is 32mm thick, while the included 92mm fan adds another 15mm. This compact layout results in a small footprint that fits well in tight spaces. The cooler weighs one pound, making it light enough for standard mounting brackets without requiring heavy-duty support. The dimensions are 97mm by 92mm for the radiator section, ensuring it does not interfere with nearby memory modules or PCIe slots in small form factor cases.
The finish includes a plating anti-oxidation protective layer on the surface. This treatment helps prevent corrosion and keeps the aluminum fins looking clean over time. It also allows for better utilization of air at the edges of the fan, improving overall heat dissipation. The design relies on a push-down mounting mechanism, which secures the cooler firmly to the socket. This simple mechanical approach ensures stability without complex brackets, making installation straightforward for users building compact systems.
Setup and daily use guide
Installation requires you to verify your motherboard socket support. The listing confirms compatibility with Intel LGA 1150, 1151, 1155, 1156, 1200, and 1700. It also supports AMD AM4. You must check if your specific board matches one of these standards before proceeding. The cooler is designed as a push-down unit, which typically simplifies mounting compared to tower designs that require side access. Its 47mm height means you can install it in tight spaces without interference from nearby RAM modules or case walls. The 97mm by 92mm radiator footprint is compact, fitting easily into small form factor cases like ITX builds. In daily use, the 92mm PWM fan adjusts its speed automatically based on CPU load. This feature helps maintain low noise levels, listed at 22.4 dB(A), while providing up to 42.58 CFM of airflow. The pure copper base ensures efficient heat transfer from the processor. The anti-oxidation plating on the fins helps prevent corrosion over time, which is useful for maintaining performance in various environments. You do not need to worry about manual fan curves if you prefer a set-and-forget approach, as the PWM control handles speed adjustments. The 1-pound weight is light, making it easy to handle during installation. Ensure your case has enough vertical clearance for the full 47mm height, including the fan thickness. This cooler is ideal for users building compact systems who need reliable cooling without the bulk of larger air coolers.
Before you buy this cooler
You should verify your case height limit before purchasing. The 47mm profile is tight, so measure carefully. This unit fits Intel LGA 1150, 1151, 1200, and 1700, plus AMD AM4. Check if your motherboard supports these sockets. The cooler includes a 92mm PWM fan, so you do not need to buy one separately. Ensure your case has enough depth for the 97mm radiator. RAM clearance matters too. Tall memory sticks might block the fan or heat pipes. Clean the copper base gently with isopropyl alcohol before installation. Dust accumulation reduces efficiency over time. Use a soft brush to remove debris. This cooler suits small form factor builds. It competes with other low-profile options. If you need higher cooling capacity, consider a tower design. For ITX systems, this compact unit is a strong choice. Verify all physical dimensions match your build constraints. Read the manual for mounting hardware details. Proper installation ensures optimal heat transfer.
Check before you buy
- Check your case supports 47mm cooler height.
- Verify motherboard socket matches LGA 1700 or AM4.
- Ensure RAM does not block the 92mm fan.
- Confirm case depth fits the 97mm radiator size.
