ARCTIC server fan S12038-8K 120x38mm 8000 rpm

ARCTIC S12038-8K — high-speed server fan

In environments with high thermal loads, such as servers from 3U, industrial systems or automation applications, reliable cooling is absolutely crucial. The ARCTIC S12038-8K fan provides a speed range from 800 to 8000 rpm, allowing you to adjust the performance to your current needs. Thanks to static pressure of 37 mmH2O, it effectively pushes air through densely packed cooling fins, while the maximum air flow 370 m³/h ensures rapid heat dissipation. Its durable design with dual ball bearings and motor protection extends its service life even in harsh conditions.

Performance and speed control

The ARCTIC S12038-8K fan provides a wide speed range from 800 to 8000 rpm, making it suitable for various applications from quiet operation to intensive cooling. PWM control or voltage control ensure precise speed control and performance optimization. This means that the fan can be adjusted for both noise minimization and maximum cooling.

Durability and reliability

This fan is equipped with dual ball bearings in a brass housing made in Japan, which increase stability, heat and dust resistance and extend the service life even at high speeds. Active motor cooling using an additional impeller reduces the operating temperature of the motor, which can double its service life. Thanks to reverse polarity protection, the motor is protected in case of incorrect connection.

Compatibility and Easy Installation

The fan is equipped with a standard 4-pin 2510 connector, which is backward compatible with 2-pin and 3-pin headers, making it easy to integrate into existing systems. With a 300mm cable length, installation flexibility is ensured. With a compact size of 120 × 120 × 38mm, it is ideal for various applications in server and industrial environments.
