Axial cooling fan Supermicro FAN-0221L4 120x120x25 mm 2200 RPM

Axial cooling fan Supermicro FAN-0221L4 120x120x25 mm 2200 RPM is a standard-size server cooling fan designed to provide steady airflow and assist heat dissipation in racks, chassis and electronic enclosures. The 120 x 120 x 25 mm frame fits common mounting patterns and the 2200 RPM nominal speed delivers balanced airflow suitable for general-purpose system cooling. The product is intended as a replacement or upgrade fan to help maintain indicated operating temperatures of components and improve long-term stability.

Advantages

The fan offers a compact, industry-standard form factor that simplifies installation in a wide range of server and chassis configurations. Its rated rotational speed provides consistent airflow while keeping acoustic output moderate for its performance class. Built with durable bearings and a reinforced frame, the fan is intended for continuous operation typical of server environments and is compatible with common 3- and 4-pin power interfaces used in many systems.

Suitable for

• Server racks and blade enclosures
• Desktop and tower chassis requiring 120 mm cooling
• Network and storage appliances
• Replacement of worn or failed system fans
• Cooling upgrade to stabilize component temperatures

Key specifications

• Frame dimensions: 120 x 120 x 25 mm
• Nominal rotational speed: 2200 RPM
• Axial fan design for directed airflow
• Standard mounting hole spacing compatible with common 120 mm cutouts
• Designed for continuous operation in electronic enclosures

How to use

Install the fan into the matching 120 mm mounting location inside the chassis or enclosure, aligning the mounting holes and securing with appropriate screws or clips. Connect the power cable to the system fan header or dedicated power supply, observing correct pin orientation for 3- or 4-pin connectors. Ensure the airflow direction matches the intended ventilation path in the chassis, usually indicated by an arrow on the fan frame. After installation, verify that the system recognizes the fan (if using a monitored header) and that the fan spins freely without obstruction.

Usage recommendations

For reliable long-term operation, mount the fan on a solid surface to minimize vibration, keep intake and exhaust paths free of dust and cable obstructions, and perform periodic cleaning. When replacing an existing fan, compare mounting hole pattern and connector type before installation. If noise level or airflow needs differ, consider fan speed control via the system BIOS or a fan controller to optimize cooling and acoustics.
