The ARCTIC S12038-4K PWM (ACFAN00296A) is a robust 120 mm cooling fan engineered for server environments, industrial systems, and high-load computing where reliable airflow and pressure are critical. With a wide PWM-controlled speed range (600 to 4000 RPM), it adapts from energy-efficient low-speed operation to strong cooling performance when needed.
Its high static pressure (11.45 mm H₂O) and substantial airflow (~180 m³/h) make it effective at moving air through restrictive environments such as dense heat sinks, server chassis, or compact industrial enclosures. The fan is built with dual ball bearings in a brass housing, improving mechanical stability and extending service life even under high thermal and dust exposure conditions.
Active cooling of the motor and included protective features like reverse polarity protection help the fan perform reliably in harsh conditions. It can be used as system ventilation, a replacement for worn fans in 3U+ server rigs, or as a reliable cooling upgrade in embedded or industrial applications.
Wide PWM Control Range:
The 600 – 4000 RPM adjustable speed range lets the fan run quietly during light loads and ramp up to powerful airflow when needed, balancing acoustics and performance.
Strong Airflow & Static Pressure:
With ~106 CFM airflow and 11.45 mm H₂O static pressure, it effectively pushes air through tight spaces, dense fins, and restrictive server racks — making it suitable for high-demand cooling tasks.
Durable Construction:
Dual ball bearings with a brass housing and active motor cooling improve stability, reduce wear, and help maintain performance over long service lives — ideal for continuous operation systems.
Versatile Compatibility:
The 4-pin PWM connector supports wide motherboard/controller integration and also works with 2-pin or 3-pin setups, giving flexibility for different system builds.
Protective Features:
Reverse polarity protection and robust design help safeguard the fan from electrical mishaps and environmental stress, increasing reliability.
Ideal for Tough Environments:
Designed for servers, industrial machines, embedded systems, and 3U+ chassis, this fan is a great upgrade or replacement for cooling components in constrained spaces.
Long Warranty Confidence:
Backed by a 6-year manufacturer warranty, giving peace of mind for long-term deployment in critical cooling applications.
