Thermalright AXP90 X36 Low Profile ITX
The AXP90 X36 is a compact 36 mm high cooler designed for ITX builds. It uses a 92 mm approach with a slim profile that helps maintain adequate airflow even in tight cases. The construction emphasizes an all-metal platform, backplate fasteners, and high-quality soldering and plating processes to ensure durability and corrosion resistance. This model focuses on delivering reliable cooling with minimal footprint while maintaining a straightforward installation process for ITX systems.
Considerations include:
- 36 mm total height ideal for very small cases.
- All-metal platform with back plate fasteners for secure mounting.
- Efficient heat transfer with a compact design.
upHere H85K6 Low Profile CPU Cooler
The upHere H85K6 is a versatile low-profile cooler designed to fit a broad range of sockets, including Intel LGA1700, LGA1851, and numerous AMD sockets. Its 85 mm height makes it adaptable for ITX and Micro-ATX builds while maintaining solid cooling performance thanks to a 120 mm PWM fan. The design emphasizes ease of installation and broad compatibility, making it a practical choice for mixed hardware setups where space is at a premium.
Key points include:
- Broad socket compatibility for Intel and AMD platforms.
- 120 mm PWM fan supports automatic speed control and quiet operation.
- Compact form factor suitable for ITX and small form factors.
Buying Guide
When choosing a low profile CPU cooler for Intel LGA 1700 systems, consider the following factors:
- Height clearance: Verify the total height fits your case, RAM, and PCIe layout. Sub-40 mm options are ideal for HTPC and SFF builds, but some models at 47 mm can still fit in many compact cases.
- Socket compatibility: Ensure the cooler supports LGA 1700 and any other platforms you plan to use (e.g., LGA 1851). Some models list wide support for AMD sockets as well.
- RAM and PCIe clearance: Footprint should not obstruct RAM slots or PCIe lanes on ITX and Micro-ATX boards. Look for a tailored footprint or slim fan design.
- Noise and cooling performance: PWM fans and Low-Noise Adapters help maintain quiet operation. Check reported noise levels and fan speeds for your workload.
- Installation complexity: Some coolers use backplates and multiple mounting steps. If you prefer a quick upgrade, choose models noted for straightforward installation.
- Aesthetic and build color: Chromax.Black variants offer a cohesive look for blacked-out builds, while brown variants suit beige or dual-tone themes.
- Reliability and compatibility with ITX cases: For small form factors, stability of mounting hardware and backplate design matters as much as raw cooling performance.
Performance comparisons across these models typically balance height against airflow. Taller low-profile options (around 47 mm) may provide stronger cooling under load but can restrict memory or PCIe clearance in very tight builds. The shortest options (36–37 mm) excel in maximal case compatibility but rely on efficient slim fans to maintain adequate CPU temperatures. For most LGA 1700 ITX systems, a 37–47 mm cooler with a 92 mm or larger slim fan provides a solid balance of cooling and quiet operation.
