The S12038-4K has a wide speed range that can be regulated via PWM and voltage. With a static pressure of 11,45 mmH₂O and a maximum airflow of 180 m³/h, the S12038-4K is a true all-rounder and is suitable for use on heatsinks, as a radiator fan or as a rack fan. The S12038-4K fits into 4U server housings and serves as an upgrade or replacement for a CPU fan, radiator fan or for system ventilation. The fan has a standard 4-pin connector and can also be connected and controlled on 2-pin and 3-pin headers, while the 30 cm cable allows flexibility in positioning.
