## Summary description

SAMA Gears U40 Black is a compact 9 cm air cooler with Hydro Dynamic Bearing (HDB). Dimensions are 90×90×47 mm. Fan speed ranges from 900 to 2800 RPM with a maximum air pressure of 2.49 mmH2O. Designed for case or component cooling where space is limited, it provides reliable airflow and reduced noise at lower speeds for desktop and small-form-factor systems.

## Long description

SAMA Gears U40 Black is a compact top-flow air cooler with a slim 47 mm profile and four heat pipes, designed to fit into small ITX and other space-constrained cases. The cooler includes a 90 mm fan with Hydro Dynamic Bearing (HDB) and a speed range of 900–2800 RPM, providing reliable airflow and moderate cooling performance for desktop and small-form-factor systems.
Advantages
The slim 47 mm height and top-flow design allow the SAMA U40 to be installed in tight enclosures without interfering with memory or other components. The 4-heatpipe configuration improves heat transfer from the CPU base to the fin stack, while the HDB 90 mm fan balances airflow and noise across its PWM-controlled speed range. Compatibility with common modern sockets ensures broad processor support.
Suitable for
Mini-ITX builds and small-form-factor PCs
Systems with limited CPU cooler clearance
Builds that require a low-profile top-flow cooler
Everyday desktop use and light to moderate workloads

Connect the fan’s PWM cable to the CPU\_FAN or designated header on the motherboard to enable automatic speed control. Verify clearance with RAM modules and case components before finalizing installation.
Usage recommendations
Use the SAMA U40 in systems where low profile and compatibility with tight cases are required. For optimal cooling, ensure adequate case airflow and set a suitable PWM fan curve in BIOS or with motherboard software to balance noise and cooling performance.
