  • View: 17

  • I. Core Parameters and Compatibility

    The golden-size design with standard dimensions of 80×80×25mm fits the internal space of most audio equipment, especially suitable for embedded installation in heat-generating areas such as power amplifier modules and DSP processing units, without requiring modification to the chassis structure.

    Dynamic Heat Dissipation Performance

    Supports DC 12V/24V dual voltage (some models are compatible with 5V), with an airflow range of 25.64–41 CFM, capable of handling the heat dissipation needs of audio equipment operating under instantaneous high current.
    PWM intelligent speed control (2000–3000 RPM) automatically adjusts the speed according to the amplifier chip temperature, maintaining a quiet 22.1 dBA noise level under low load and rapid cooling under high load.

    II. Audio Scenarios Specific Optimization

    Acoustic Compatibility Design

    Hydrodynamic fan blades + silicone damping bearings achieve a minimum operating noise of 22.1 dBA, lower than the ambient noise level perceptible to the human ear.
    Soft-start technology avoids the "pop" sound caused by the current surge during startup, ensuring smooth speed switching without mechanical resonance.

    Electromagnetic Interference Protection: Employs a PBT 94V-0 flame-retardant material frame with an insulation impedance exceeding 500 MΩ, effectively suppressing electromagnetic interference (EMI) from the fan motor to the audio signal circuitry.

    III. Industrial-Grade Reliability

    Long lifespan guaranteed by dual ball bearings and a self-lubricating system, supporting 24-hour continuous operation and an 80,000-hour lifespan (40℃ environment), far exceeding the typical usage intensity of audio equipment.

    Environmental Adaptability

    Operating temperature range -20℃~75℃, suitable for complex environments such as stage equipment and car audio systems. PC+glass fiber composite material shell, resistant to moisture and corrosive gases, meeting the requirements for a sealed environment inside audio equipment.

    IV. Typical Application Recommendations

    Hi-Fi Amplifier: 24V version recommended (e.g., model 8025-B), installed near the heatsink fins to create a directional airflow.
    Professional Mixing Console: When multiple fans are connected in parallel, PWM synchronous control is recommended to avoid harmonic noise caused by speed differences.
    Car Audio Retrofit: Requires installation with a vibration-damping bracket; 12V low-voltage version is preferred.

    This series of products can be quickly wired using wire polarity (red positive, black negative). Some models offer dust filter options.
