Featuring a wide 250–6000 RPM range with PWM control, dual ball bearings for durability, and a robust airflow of 12.06 m³/h at 4.2 mm/H2O static pressure, it balances efficient cooling with quiet operation. Its 4-pin connector and flexible cable length make it ideal for servers, NAS, mini PCs, and other compact electronics requiring reliable thermal management. ## Description Product description Designed for continuous operation 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. Full control with a wide speed range 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. High airflow and static pressure With a static pressure of 4.2 mmH₂O 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. Wide range of applications The S4028-6K fits into 1U server cases and can serve as a replacement fan for routers, switches and NAS. It can also be used for other products such as DVRs, mini PCs, HTPCs, hard drive enclosures and 3D printers.
