Designed for Continuous Operation
The impeller of the S4028-6K is held by two high-quality Japanese ball bearings in a sturdy brass housing. This design increases the stability, strength and perpendicularity of the fan and minimises sensitivity to influences such as heat and dust. In addition, the brass housing helps to reduce wear on high-speed fans.
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.
Flexible Connection Options
The fan has a standard 4-Pin fan connector and can also be connected to and controlled on 2-Pin or 3-Pin headers, while the 40cm cable allows a lot of flexibility in positioning.
