Application
This fan is specifically designed for high-performance computing and embedded systems where the compact 40 mm frame must deliver aggressive cooling against high thermal loads and restricted airflow pathways. Its capability for PWM speed regulation and real-time FG feedback makes it an indispensable component in 1U and 2U enterprise server units, storage arrays, high-power network switches, and custom industrial machinery that requires dynamic, reliable, and high-pressure spot cooling for processors, VRMs, or dense memory modules.
