ARCTIC S4028-6K server fan, 4-pin, 40mm

Server fan S4028-6K, 6000 RPM, 4-pin, 40mm, black.
Features:
Designed for continuous operation. The double-row ball bearing is extremely durable and less sensitive to external influences. It is much less affected by contamination and high temperatures than conventional sleeve or ball bearings. It is an excellent choice if you want to ensure uninterrupted operation at maximum speed.
Full control and wide speed range The S4028-6K has a very wide speed range that can be adjusted by PWM and voltage. The maximum speed of 6000 rpm provides a good balance between cooling power and noise.
High airflow and static pressure. This fan guarantees extremely efficient cooling, even with increased air resistance. With a static pressure of 4.2 mmH2O and a maximum air flow of 12.06 m³/h, the S4028-6K is a true universal fan, suitable for use as both a radiator and a case fan.
Wide application The S4028-6K fits into 1U server chassis and can be used as a replacement fan for routers, hubs, and NAS. It can also be used in other products such as video recorders, mini PCs, HTPCs, hard drive enclosures, and 3D printers.
Flexible connection options The fan has a standard 4-pin fan connector, but can also be connected and controlled with 2 or 3-pin connectors, and the 40 cm long cable allows for flexible positioning.
