Fan QNAP FAN-12CM-T01 120 mm 12 V 1850 RPM Black — computer cooling fan

QNAP FAN-12CM-T01 is a 120 mm computer cooling fan with a 12 V supply and a maximum rotational speed of 1850 RPM. The fan measures 120 × 120 × 25 mm and comes in a black finish. It is designed for general-purpose cooling of computer cases, NAS units and other electronics where steady airflow is required for heat dissipation and temperature control of components.

Advantages

The fan delivers a balance of airflow and moderate noise due to its 1850 RPM maximum speed, making it suitable for continuous operation in confined electronic enclosures. Its standard 120 × 120 × 25 mm form factor ensures compatibility with many mounting points in PC cases and NAS devices. The 12 V supply is compatible with common motherboard and power supply headers, allowing straightforward installation and integration into existing cooling setups.

Suitable for

• Cooling computer cases and workstations
• Ventilation for NAS enclosures and small servers
• Replacement or upgrade of existing 120 mm case fans
• Cooling electronic enclosures, power supplies or DIY projects

Key specifications

• Size: 120 × 120 × 25 mm
• Rated voltage: 12 V
• Maximum rotational speed: 1850 RPM
• Colour: Black
• Application: Case and enclosure cooling

How to use

Mount the fan in the intended location using compatible screws or brackets for a 120 mm fan. Connect the fan cable to a 12 V fan header on the motherboard, a dedicated fan controller, or a compatible power source, observing correct connector orientation and polarity. Ensure the airflow direction matches your cooling plan—usually indicated by arrows on the fan frame—and secure cabling to prevent contact with moving blades. After installation, verify operation and monitor system temperatures to confirm improved airflow and stable component temperatures.

Recommendations

For effective cooling, position the FAN-12CM-T01 to create a consistent airflow path through the case or enclosure. Combine it with other intake and exhaust fans to establish balanced air movement. Regularly clean the fan blades and filter areas to maintain performance and check mounting points for vibration. When replacing a fan, match the voltage and physical size to ensure compatibility.
