Product Title
SANYO DENKI San Ace 38 Ultra-Low-Noise DC Fan – 9GA0312P3J001 | 38x28mm, 12V, 6.2W, 23,500 RPM, 57.5dB(A), PWM & Pulse Sensor
Product Overview
The SANYO DENKI 9GA0312P3J001 represents the pinnacle of acoustic engineering within the San Ace 38 Low Power series. Designed for applications where minimal audible disturbance is non-negotiable, this model operates at an industry-leading 57.5 dB(A) while consuming just 6.2 Watts — making it the quietest and most energy-efficient variant in its class.
Operating at a reduced speed of 23,500 RPM, it delivers 0.57 m³/min (20.1 CFM) airflow and 720 Pa (2.89 inchH₂O) static pressure — sufficient for passive cooling in low-heat-density systems such as audio amplifiers, patient monitors, and laboratory analyzers. Its ribbed plastic frame ensures structural integrity without compromising acoustic performance.
Equipped with PWM speed control and a pulse sensor, it enables intelligent thermal management and real-time diagnostics. Certified as an Eco Product by SANYO DENKI and compliant with global safety standards, it supports sustainable design goals while delivering unparalleled silence.

Applications
This ultra-quiet, ultra-low-power fan is optimized for:
-
High-Fidelity Audio Equipment: Amplifiers, DACs, preamps — where even minor fan noise ruins listening experience.
-
Medical Monitoring Devices: Patient vital signs monitors, ECG machines — requiring silent operation in hospitals or homes.
-
Precision Laboratory Instruments: Spectrometers, microscopes, chromatographs — needing stable, vibration-free cooling.
-
Consumer Electronics: Smart speakers, VR headsets, gaming consoles — prioritizing immersive, distraction-free experiences.
-
Broadcast & Studio Gear: Mixing consoles, recording interfaces — where background noise must be eliminated.
-
Green Technology Systems: Solar charge controllers, IoT sensors — maximizing runtime on limited power budgets.
Wiring & Connection Guide
Standard 4-wire interface:
-
Red Wire: +12V Power Input
-
Black Wire: Ground (GND)
-
Yellow Wire: Pulse Sensor Output (Open collector, 2 pulses per revolution)
-
Blue Wire: PWM Control Input (Typical frequency: 25kHz)
Installation Note: For optimal silence, configure PWM duty cycle to match actual thermal load. Leaving PWM pin open may result in full-speed operation depending on controller logic.
