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
The S4028-15K fits in 1U server cases, as a replacement fan for routers, switches and NAS. It can also be used for other products such as DVRs, Mini PCs, HTPCs, hard disk enclosures and 3D printers
The fan has a standard 4-pin fan connector and can also be connected and controlled on 2-pin or 3-pin headers, while the 40 cm cable allows enough flexibility in positioning
