ARCTIC S4028-15K (5 Pack) – 40x40x28 mm Server Fans, 1400–15000 RPM, PWM Regulated, 4-pin Connector, 12 V DC, Rack Cooling Fan – Black

About this item TheS4028-15K’s impeller is held in place by two ball bearings, making it both particularly durable and less sensitive to external influences like heat and dust The S4028-15K has a particularly wide speed range that can be regulated via PWM and voltage. With its 15000 max RPM it is one of the strongest 12 V fans with a 40 mm diameter 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 Product Description 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 mmH₂O 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.
