Who it fits
Good fit for
This cooler suits users building ITX systems or compact PCs where space is limited. If your case requires a cooler under 50mm, this 47mm design fits. It works well for Intel LGA 115x/1200/1700/1851 and AMD AM4/AM5 platforms. The included 92mm fan helps keep noise below 22.4 dBA. You should choose this if you need a reliable, low-profile solution that supports modern sockets without requiring excessive clearance.
Who should skip it
Skip this option if you need high cooling performance for overclocked processors. The 47mm height and single 92mm fan limit thermal capacity. Users with large tower cases or high-TDP CPUs may find this insufficient. The cooler is designed for low-profile builds, not extreme cooling needs. If you require more heat dissipation, consider a larger air cooler with more heatpipes and a bigger fan size for better thermal results.
Verdict: The Thermalright AXP90 X47 is a solid choice for low-profile builds requiring broad socket support. It balances size and cooling capability for compact ITX systems.
Key specs explained for you
Cooler Height: 47mm
This measurement defines the vertical space the cooler occupies above the CPU socket. A 47mm profile fits inside compact ITX cases where standard air coolers are too tall. You must verify your case clearance against this number before purchasing. If your case supports only 60mm, this unit fits. Larger towers offer more cooling potential but require more vertical room.
Fan Size: 92mm
The included fan measures 92mm across. Smaller fans often spin faster to move the same amount of air, which can increase noise levels. A 92mm fan generally runs quieter than a 120mm fan at similar airflow but may have lower maximum airflow capacity. This size balances noise and cooling for low-profile designs. Check your case for 92mm fan compatibility.
Heat Pipes: 4
The cooler uses four heat pipes to transfer heat from the base to the fins. More pipes typically improve heat distribution across the fin stack. This helps maintain consistent cooling performance under load. Compare this count with other low-profile models. Units with fewer pipes may struggle with higher TDP processors. Four pipes are standard for this size class.
Socket Compatibility: AM4, AM5, LGA115x/1200/1700/1851
This list shows which CPU sockets the mounting hardware supports. It covers most modern AMD and Intel platforms. You need to ensure your motherboard socket matches one of these options. The inclusion of AM5 and LGA1700/1851 indicates recent compatibility. Older sockets like LGA115x are also supported. Verify your specific motherboard model against this list to avoid fitment issues.
Design and build quality
According to the listing, this cooler features an all-metal platform with a black nickel plating process. This finish provides corrosion resistance and acid alkali resistance. The construction uses a secondary reflow soldering process to attach the four 6mm heat pipes to the base. This method aims to lower thermal resistance and improve heat transfer efficiency from the CPU to the fins. The total height is 47mm, which equals 1.26 inches. This low profile allows it to fit inside compact ITX cases where standard air coolers are too tall. You must verify your case clearance against this number before purchase.
The unit weighs 1.1 pounds and measures 3.74 inches in width and length. It includes a 92mm TL-9015B slim PWM fan. The fan operates at 12V with a maximum current of 0.2A. Noise levels are listed at 22.4 dBA or less. This quiet operation suits small builds where fan noise is noticeable. The cooler supports Intel sockets 115x, 1200, 1700, and 1851, as well as AMD AM4 and AM5. It uses a back plate fastener for mounting. This design ensures stability on various motherboard formats. The compact size and specific socket support make it a practical choice for mini-ITX systems. You should check your motherboard layout to ensure the fan does not block RAM slots.
Setup and everyday use
Installing this cooler requires careful planning for your specific motherboard socket. The listing confirms support for Intel LGA 115x, 1200, 1700, and 1851, as well as AMD AM4 and AM5 platforms. You must verify that your case allows for the 47mm height. The included 92mm PWM fan connects to your motherboard header for speed control. This allows you to adjust noise levels based on your cooling needs. The fan draws a maximum of 0.2A at 12V. Noise output is rated at 22.4 dBA or less under load. This low noise profile suits quiet office builds or home theater PCs. The all-metal platform and secondary reflow soldering suggest a durable connection between the heat pipes and base. This construction method typically ensures consistent heat transfer over time. You benefit from the black nickel plating, which resists corrosion and acid alkali exposure. This finish helps maintain performance in varied environmental conditions. The compact width of 3.74 inches and length of 3.74 inches fit most standard footprints. However, you should check for clearance around RAM slots or VRM heatsinks. The back plate fastener provides a secure mounting method for stability. Everyday use involves monitoring fan speeds via your BIOS or software. The PWM feature allows for automatic adjustments without manual intervention. This cooler is designed for ITX systems where space is at a premium. You get reliable cooling without the bulk of larger towers. The weight of 1.1 pounds is manageable for most motherboards. Ensure your case supports low-profile coolers before purchase. This setup is straightforward if you follow the mounting instructions for your specific socket type.
Before You Buy This Cooler
You should verify that your case supports the 47mm height before purchasing. This cooler is designed for ITX systems, so confirm your motherboard layout allows for the backplate fastener. The listing notes support for Intel LGA 115x, 1200, 1700, and 1851, plus AMD AM4 and AM5. You must ensure your specific socket is compatible. Since it includes a 92mm PWM fan, you do not need to buy a separate fan for basic operation. However, check that your motherboard has a header for the 12V PWM signal. Regular maintenance involves cleaning dust from the fins and heat pipes to maintain efficiency. The black nickel plating helps resist corrosion, reducing the need for special care. This option fits alongside other low-profile choices in our guide. It suits users who prioritize compact size over maximum thermal headroom. If you need higher performance, consider the taller variants listed here. Always double-check your case dimensions against the 47mm specification to avoid fitment issues.
Check before you buy
- Verify your case allows 47mm of CPU cooler clearance
- Confirm your motherboard socket is supported by the cooler
- Check that your motherboard has a 4-pin PWM fan header
- Ensure your ITX board layout fits the backplate fastener
