ARCTIC server fan S12038-4K 120x38mm 4000 rpm

ARCTIC S12038-4K — powerful server fan

In demanding server environments and industrial applications, reliable and efficient cooling is key. The ARCTIC S12038-4K fan with dimensions of 120 × 120 × 38 mm provides air flow up to 180 m³/h and static pressure 11.45 mmH2O, ensuring exceptional performance even when cooling densely packed cooling fins. Thanks to the wide speed range 600–4000 rpm with PWM control support, it allows precise adjustment to the needs of a specific application. In addition, it is equipped with a design for a long service life, even in harsh conditions.

Performance and control flexibility

The ARCTIC S12038-4K fan is ideal for cooling processors, heat sinks or general ventilation of server cabinets from 3U. The wide speed range 600-4000 rpm allows speed regulation according to current needs using PWM or voltage control. This fan adapts to both high airflow requirements and quiet operation requirements.

Design for long life

Dual Japanese-made ball bearings housed in a solid brass housing guarantee rotational stability and resistance to high temperatures and dust. This design minimizes wear during long-term operation and high speeds. Active motor cooling with an additional impeller further reduces the operating temperature of the motor, which can double its service life.
