9RA0824G10011 9RA Type Low Noise Fan
24V DC x 80x80x25 mm — Low Noise Fan with PWM Control for Quiet Cooling Applications
9RA0824G10011 Product Overview
The 9RA0824G10011 is a high-performance, low-noise DC axial fan from Sanyo Denki's San Ace 80RA Series, designed for electronic cooling in applications requiring efficient airflow with low acoustic noise and PWM speed control. The G10011 variant features an 80x80x25 mm frame size and includes PWM control for precise speed regulation and a pulse sensor (tachometer) for RPM monitoring.
Rated for 24 V DC nominal voltage with an operating voltage range of 20.4 V to 27.6 V, it provides an airflow of 0.94 m³/min (33.2 CFM) with static pressure of 52 Pa. Speed is 3300 RPM and noise level is 24 dB(A). Input current is 0.060 A. Mass is approximately 0.10 kg and operating temperature ranges from -20°C to +70°C. The motor utilizes a ball bearing system for extended service life.

9RA0824G10011 Key Advantages
The 9RA0824G10011 employs a high-efficiency motor design with optimized impeller blades to deliver effective airflow in a standard 80x80x25 mm form factor with exceptionally low noise levels. The 33.2 CFM airflow and 52 Pa static pressure provide adequate cooling for a wide range of electronic systems while maintaining an ultra-quiet 24 dB(A) noise profile. The PWM control allows precise speed regulation to balance cooling performance and noise levels, while the ball bearing construction ensures long lifespan and reliability. The pulse sensor output provides real-time RPM feedback for system monitoring and fan failure detection.
9RA0824G10011 Typical Applications
High-density servers and storage systems
Telecommunications equipment and base stations
Medical equipment and diagnostic instruments requiring low noise
Networking equipment (routers, switches, gateways)
Industrial electronic enclosures and panel PCs
High-performance computing (HPC) systems
Why Choose the 9RA0824G10011?
The 9RA0824G10011 combines 24V DC operation, 33.2 CFM airflow, and 24 dB(A) ultra-low noise in an 80x80x25 mm package with PWM control and long-life ball bearings. Manufactured by Sanyo Denki, it delivers stable, reliable, and exceptionally quiet cooling for demanding server, telecom, medical, and industrial applications. The ultra-low noise design and PWM control offer the distinct advantage of effective cooling in noise-sensitive environments with precise speed regulation, enabling optimal thermal management in space-constrained electronic systems.
