Läuft auch mit Schutzgitter nicht so laut wie andere Serverlüfter- (Kein heulen, das weit trägt und nervt).
Kräftiger Lüfter allerdings etwas harter anlauf mit 1 Ampere kurzzeitig aber kein problem wenn mit PWM Temperaturregler läuft Jedoch mit einem Boost regler vom USB 2,4 Ampere auf 12 Volt problematisch
Muss mit 9 Volt einstellen und dann hochdrehen.
Direkte 5 Volt nimmt er 0,1 Ampere auf und ist stärker als mein anderer USB Fan der mit 0.3Ampere aufnahme läuft.

Designed for Continuous OperationThe impeller of the S8038-7K is held in place by two ball bearings, making it not only particularly durable but also less sensitive to external influences such as heat and dust. |
Full Control with a wide Speed RangeThe S8038-7K has a wide speed range that can be regulated via PWM and voltage, allowing it to be tuned to the specific system requirement. With a wide speed range from 500 rpm to 7000 rpm, it provides an ideal balance between cooling performance and noise, ensuring optimal performance in various scenarios. |
High Airflow and Static PressureHeat sinks and radiators benefit from fans with high static pressure. The S8038-7K has a static pressure of 25 mmH₂O, which enables it to push air, even through narrow cooling fins. At the same time, it achieves a maximum airflow of 118.93 m³/h allowing it to quickly dissipate heat from enclosures. These properties make it the ideal choice for a wide range of applications. |

Flexible Connection OptionsWith its standard 4-pin fan connector, the S8038-7K can also be connected to 2-pin or 3-pin sockets, and then be controlled by voltage. The 30 cm cable allows a lot of flexibility in positioning. |
Active Cooling for Extended Motor LifespanThe lifespan of fans is mostly determined by the lifespan of the motor, which is significantly dependent on the motor temperature, especially in long-term operation. The motor of the S8038-7K is actively cooled by an additional impeller in the fan hub. By maintaining lower motor temperatures, its lifespan is extended by up to 50 %. This advance not only leads to improved operating efficiency, but also to significant cost savings in the long run. |
Wide Range of ApplicationsThe S8038-7K fits into 2U server cases and serves as an upgrade or replacement for a CPU fan, radiator fan or for system ventilation. 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 assures performance in various hardware environments and ensures efficient cooling and minimal downtime. |
