Ventilator ARCTIC S12038-4K 120 mm 4000 tpm serverventilator 3-pack

New Standard in Energy Efficiency

For the same performance, the S12038 consumes 12 % less than the next best competitor, improving the energy efficiency of your server. The reduction of the power consumption is the result of months of motor optimization by ARCTIC engineers with the aim to increase the IT equipment efficiency.Test SetupFan on Freezer 4U heat sink on 400 W heating element; fan speed set so that the temperature of the heating element is constantly 20 °C above the ambient temperature.

Wide Range of Speeds (600 to 4000 rpm)

The S12038-4K features a wide range of speeds from 600 to 4000 rpm, which can be controlled either via PWM or voltage regulation.. This wide range enables precise adjustment of the fan to the specific requirements of the server, ensuring efficient cooling performance under different operating conditions. The fan is equipped with a standard 4-pin connector, which also allows connection to 2-pin or 3-pin headers. The 30 cm long cable offers additional flexibility in fan placement.

Active Cooling for Extended Motor Lifespan

A 10 °C lower motor temperature roughly doubles the service life. The motor of the S12038-4K 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 to cover the fan hub impeller is included in the packaging.

Ideal for Server Environments

Especially in server environments, fans with a high pressure are required to enable sufficient air circulation in the often tightly packed enclosures. The S12038-4K fits into server cases from 3U and serves as an upgrade or replacement for a CPU fan, radiator fan or for system ventilation.

Ideal for Industrial Application

In addition to server cooling, it is 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 and ensures efficient cooling and minimised downtimes.

High Airflow and Static Pressure

Heat sinks and radiators benefit from fans with high static pressure. The S12038-4K has a static pressure of 11,45 mmH₂O, which enables it to push air, even through narrow cooling fins. At the same time, it achieves a maximum airflow of 180 m³/h allowing it to quickly dissipate heat from enclosures. These properties make it the ideal choice for a wide range of applications.

Designed for Continuous Operation

The impeller of the S12038-4K is held by two high-quality Japanese ball bearings in a sturdy brass housing. This design increases the stability, strength and perpendicularity of the fan and minimises sensitivity to influences such as heat and dust. In addition, the brass housing helps to reduce wear on high-speed fans.

Quality You Can Rely On

70 °C ambient temperature, high dust exposure and changing humidity - we carry out our long-term tests under these extreme conditions to ensure the service life of our products. Some of these test fans have been running for over 15 years.This not only allows us to continuously improve our products, but the excellent test results also confirm our high manufacturing quality. We are happy to pass this assurance on to our customers and offer a 6-year manufacturer's warranty.

How to use

Install the fans in compatible 120 mm mounting points in server or workstation chassis, ensuring correct airflow direction for system cooling. Connect to appropriate fan headers or power connectors following the server manufacturer's specifications. Secure mounting with screws and verify that the fans spin freely before powering the system. Monitor temperatures after installation to confirm effective airflow and cooling performance.

Recommendations

For optimal longevity and performance in continuous-operation environments, maintain regular dust management in the chassis, verify proper airflow paths, and replace fans if bearings exhibit increased noise or reduced RPM. Use in systems that support 120 mm fans and consult the server or chassis manual for connector and speed-control compatibility.
