Pack of 3 Arctic S12038-8K/ 12cm Fans

New standard in energy efficiency

With the same performance, the S12038 consumes 22% less power than its closest competitor, improving the energy efficiency of your server. This reduction in energy consumption is the result of months of engine optimization by ARCTIC engineers, aimed at increasing the efficiency of IT equipment.

Test setup

Fan on the 4U freezer heatsink on the 500W heating element; fan speed set so that the heating element temperature is constantly 20°C above ambient temperature.

Wide speed range (800 to 8000 rpm)

The S12038-8K offers a wide speed range, from 800 to 8000 rpm, which can be controlled via PWM or voltage regulation. This wide range allows precise tuning of the fan to the specific needs of the server, ensuring efficient cooling performance under various operating conditions. The fan is equipped with a standard 4-pin connector, which also allows connection to 2- or 3-pin connectors. The 30 cm long cable offers greater flexibility in fan placement.

Active cooling for longer engine life

A 10°C lower motor temperature practically doubles its service life. The S12038-8K´s motor is not only particularly efficient but is also actively cooled by an additional impeller in the fan hub.

To ensure a long service life in particularly dusty environments, a sticker is included in the packaging to cover the fan hub impeller.

Ideal for server environments

Especially in server environments, high-pressure fans are required to ensure adequate air circulation in the often compact enclosures. The S12038-8K fits server enclosures from 3U and up and serves as an upgrade or replacement for a CPU fan, a radiator fan, or for system ventilation.

Ideal for industrial applications

In addition to server cooling, it´s also used in industrial systems and plays an important role in machine control and automation systems. Reliable and robust, it guarantees performance in various hardware environments, ensures efficient cooling, and minimizes downtime.

High airflow and static pressure

Heat sinks and radiators benefit from fans with high static pressure. The S12038-8K has a static pressure of 37 mmH₂O, allowing it to force air even through narrow cooling fins. At the same time, it achieves a maximum flow rate of 370 m³/h, allowing it to quickly dissipate heat from housings. These properties make it the ideal choice for a wide range of applications.
