ARCTIC S12038-4K/ S12038-8K Server Fan, 120x120x38 Mm, PWM Regulated, 4-pin Connector, 12 V DC, Rack Cooling Fan

About S12038-4K ● The impeller of the S12038-4K is held in place by two ball bearings with Brass Housing, making it not only particularly durable but also less sensitive to external influences such as heat and dust ● The S12038-4K has a wide speed range that can be regulated via PWM and voltage. With up to 4000 rpm, it provides an ideal balance between cooling performance and noise ● With a static pressure of 11.45 mmH₂O and a maximum airflow of 180 m³/h, the S12038-4K is a true all-rounder and is suitable as both a radiator fan and a case fan ● The S12038-4K fits into Server Cooling for Home Servers and Data Centres cases and serves as an upgrade or replacement for a CPU fan, radiator fan or for system ventilation ● The fan has a standard 4-pin connector and can also be connected and controlled on 2-pin and 3-pin headers, while the 30 cm cable allows flexibility in positioning About S12038-8K ● The impeller of the S12038-8K is held in place by two ball bearings with Brass Housing, making it not only particularly durable but also less sensitive to external influences such as heat and dust ● The S12038-8K has a wide speed range that can be regulated via PWM and voltage.
