Arctic S4028-6k 40x40x28 Mm Server Fan 250-6000 Rpm Pwm Cooler

The S4028-6K's impeller is held in place by two ball bearings, making it both especially durable as well as less sensitive to external influences such as heat and dust

The S4028-6K has a particularly wide speed range that can be regulated via PWM and voltage. With its 6000 RPM max it offers a well-balanced ratio between cooling power and noise

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 radiator and case fan

The S4028-6K 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 its 40 cm cable allows enough flexibility in positioning
