80mm Case Fan with PWM Control, 5005000 RPM, Optimized for Air Pressure, Fluid Dynamic Bearing

80mm Case Fan with PWM Control, 5005000 RPM, Optimized for Air Pressure, Fluid Dynamic Bearing This 80mm fan is designed for efficient cooling in environments.It operates within a speed range of 500 to 5000 RPM, enabling precise control through pulse width modulation (PWM).Below 5% PWM input, the fan stops completely, allowing silent during idle periods.Equipped with a 4-pin connector, the fan supports infinitely variable speed adjustment between 500 and 5000 RPM when PWM exceeds 5%.This flexibility allows tailored airflow management based on thermal requirements.At 3000 RPM and 12 volts, it consumes only 0.669 watts, drawing 0.06 amps, contributing to low power usage.The fan delivers up to 40 CFM of airflow while generating a pressure of 5.3 mmH2O, making it suitable for use with heat sinks, radiators, pin fins, and filters where airflow resistance is present.Its closed ring impeller design supports stable rotation even under increased air resistance.A fluid dynamic bearing provides smooth and quiet at low speeds while maintaining function at maximum speed.The focused airflow design ensures effective heat dissipation, particularly in compact systems such as 2U server racks that require efficient cooling under constrained conditions.
