The impeller of the S4028-6K is held in place by two ball bearings and is therefore particularly durable and less sensitive to external influences such as heat and dust. The S4028-6K has a very wide speed range that can be regulated via PWM and voltage. With its 6000 rpm max, it offers a good balance between cooling power and noise. With a static pressure of 4.2 mm/H2O and a maximum airflow of 12.06 m³/h, the S4028-6K is a true all-rounder and is suitable as both a radiator and case fan.
