Zalman ZM-F3 FDB(SF) computer cooling system Computer case Fan 12 cm Black, Transparent

The Zalman ZM-F3 FDB(SF) 120 mm case fan delivers quiet, durable cooling for PC enclosures. It features a Fluid Dynamic Bearing (FDB) that forms a high-pressure oil layer to reduce shaft friction, extending service life up to 150,000 hours. The fan has a black-transparent design, runs at 12 V with a maximum speed of 1200 RPM and measures 120 x 120 x 25 mm.

Advantages

Fluid Dynamic Bearing technology minimizes mechanical wear and noise by creating a lubricating oil layer at microchannel intersections, resulting in long lifespan and stable operation. The shark fin blade design reduces turbulence to improve airflow while lowering vibration and acoustic output. Low maximum RPM further decreases noise levels, and included silicone vibration-absorbing pins reduce transfer of vibration to the case.

Suitable for

• Case cooling for desktop PCs
• Replacement or upgrade of 120 mm case fans
• Silent or low-noise system builds

How to use

Install the fan in a compatible 120 mm mounting location inside the PC case, aligning the airflow direction markers if present. Connect the fan connector to an available 3- or 4-pin motherboard header or to a fan controller according to the system’s wiring. Secure the fan using screws or the supplied silicone pins to dampen vibration. Ensure unobstructed airflow and proper cable routing before powering the system.

Recommendations

For quieter operation, mount the Zalman ZM-F3 FDB(SF) in intake or exhaust positions with minimal obstructions and use the silicone pins provided. Regularly check for dust buildup and clean the fan blades to maintain optimal airflow and long bearing life.
