S4028-15K 40 mm Server Fan DESIGNED FOR CONTINUOUS OPERATION The impeller of the S4028-15K 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 S4028-15K has a very wide speed range that can be regulated via PWM and voltage. With its 15000 rpm max, it offers a high cooling capacity at a relatively low noise. HIGH AIRFLOW AND STATIC PRESSURE With a static pressure of 26.5 mm/H2O and a maximum airflow of 32.67 m3/h, the S4028-15K is a true all-rounder and is suitable as both a radiator and case fan. WIDE RANGE OF APPLICATIONS The S4028-15K 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.
