S4028-6K 40 mm Server Fan 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 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. 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.
