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

The Zalman ZM-F3(SF) 12 cm Black is a computer case fan designed to provide steady airflow while maintaining low noise levels. It measures 120 × 120 × 25 mm, runs at a maximum of 1200 RPM with a 12 V supply, and uses a long-life sleeve bearing (EBR) to reduce dust ingress and extend operating life. The fan features a shark fin blade profile and includes silicone vibration-dampening pins for quieter operation.

Advantages

Long Life Bearing (EBR) reduces friction and dust entry to prolong service life. The shark fin blade design optimizes airflow and lowers turbulence, which decreases noise and vibration. Low maximum RPM and supplied silicone pins further minimize operational noise and absorb vibrations between the fan and the case.

Suitable for

• General PC case cooling
• Silent or low-noise system builds
• Small and mid-tower computer enclosures

How to use

Mount the fan in the desired case location using the provided screws or silicone pins to reduce vibration. Connect the fan to a compatible 3- or 4-pin header or to a 12 V fan power connector on your motherboard or power supply. Ensure the airflow direction matches your case cooling configuration (intake or exhaust). Regularly check for dust build-up and clean the fan as part of routine maintenance to preserve performance and bearing life.

Recommendations

For quiet operation, install the fan in positions where airflow requirements are moderate and combine with other low-RPM fans if higher cooling performance is needed; avoid excessive dust exposure and clean periodically to maintain the long-life bearing performance.
