The high heat dissipation efficiency of Sanyo Denki's San Ace series fans stems from three core breakthroughs: aerodynamic design, material and process innovation, and intelligent control technology. Below is a detailed analysis from technical principles to practical applications:
I. Core Technology: Innovations from Aerodynamics to Materials Science
1. Balanced Design for High Static Pressure and Large Airflow
Through optimized multi-blade structures and curved airfoil designs, Sanyo Denki fans achieve superior performance in both static pressure and airflow. For instance, the San Ace 8025 fan (model: 9GA0824P4G001) generates a static pressure of 150 Pa and an airflow of 67.4 CFM at 6800 RPM. Compared with similar products, its static pressure is increased by 20% and airflow by 18%. This design enables it to effectively penetrate heat dissipation fins in dense cooling scenarios (e.g., server racks, industrial control cabinets) and ensure rapid heat exhaustion.
2. Intelligent PWM Speed Regulation and Real-Time Feedback
The fan is equipped with a built-in PWM control chip, which dynamically adjusts the rotation speed (0-100% duty cycle) based on device temperature. For example, in AI servers, when GPU load increases, the fan speed automatically rises to the maximum, reducing the chip temperature by 8°C and cutting computing power loss by 15%. Meanwhile, the FG speed feedback signal (1 pulse/revolution) enables real-time monitoring of operating status, helping maintenance personnel identify potential faults in advance.
3. Low Power Consumption and High Energy Conversion Efficiency
Adopting brushless DC motors and low-resistance coils, Sanyo Denki fans reduce power consumption by over 20% compared to traditional fans under the same airflow. For example, the San Ace 200 series fan (model: 9GA2048P0G001) achieves an airflow of 1084 CFM with a power of 384W, reaching an industry-leading energy efficiency ratio (sanyofan.cn) and complying with the EU ErP energy efficiency standards.
II. Structural Innovation: Precision Optimization from Bearings to Blades
1. Long-Life Ball Bearing Technology
Compared with oil-impregnated bearings, the double ball bearings used in Sanyo Denki fans extend the service life to 40,000 hours (at 60°C) and improve vibration resistance by 50%. In industrial automation equipment, this bearing design ensures stable fan operation under high-frequency impacts—for example, inverters in a certain automobile factory have maintained zero faults for 2 years after using these fans.
2. Integrated Aluminum Alloy Frame and Lightweight Blades
The fan frame is made of high thermal conductivity aluminum alloy, which improves heat dissipation efficiency by 30% compared to plastic frames. Meanwhile, the trapezoidal blade design (wide at the root, narrow at the top) reduces airflow turbulence during high-speed rotation, lowering noise while increasing air pressure. For instance, the San Ace 80T wide-temperature fan maintains an airflow of 65.7 CFM and a static pressure of 143 Pa even in environments ranging from -40°C to +85°C.
3. IP Protection and Wide-Temperature Adaptability
Some models (e.g., 9WPA series) support IP68 waterproof and dustproof ratings, with fully sealed motors and circuit boards that can operate normally even after being immersed in 1 meter of water for 30 minutes. Additionally, the wide temperature range of -20°C to +70°C allows stable operation in extreme environments such as outdoor charging piles and rail transit. A certain brand of outdoor fast-charging piles has achieved zero faults for 1 year after using these fans.
III. Measured Data and Industry Validation
1. Comparison of Server Heat Dissipation Efficiency
In a test of an AI computing cluster, after installing the Sanyo Denki San Ace 8025 fan, the GPU core temperature dropped from 85°C to 77°C, and training efficiency increased by 15%. In contrast, a same-size Nidec fan only reduced the temperature by 6°C under the same conditions.
2. Balance Between Noise and Energy Efficiency
At 5400 RPM, the noise level of the Sanyo 9WPA fan is 36 dB(A), 5 dB lower than similar products, while its static pressure is 15% higher than that of the Akasa OTTO SC12. This "low-noise, high-static-pressure" feature makes it outstanding in medical equipment—for example, a certain ventilator brand improved its temperature control accuracy from ±2°C to ±0.5°C after using this fan.
3. Reliability Validation in Industrial Scenarios
In the control system of a certain subway train, Sanyo Denki's G-resistant fan (supporting 50G acceleration) operated continuously for 2 years without faults, while competitors had a failure rate as high as 12% due to bearing wear. This reliability comes from its integrated structural design and precision dynamic balance adjustment, ensuring stable airflow even during high-speed rotation.
IV. Application Scenarios and Solutions
1. High-Density Computing Equipment
In 1U/2U servers, Sanyo Denki fans penetrate dense heat dissipation fins via high static pressure and achieve precise temperature control with PWM speed regulation. After a data center adopted the San Ace 200 series, its PUE (Power Usage Effectiveness) decreased from 1.4 to 1.25, saving 20% in annual energy costs.
2. New Energy and Outdoor Equipment
In energy storage systems, the combination of fans and heat sinks reduces the temperature of PCS modules by 10-15% and improves system efficiency by 3%. In charging piles, the IP68 protection and wide-temperature design ensure stable operation in environments from -10°C to +40°C, extending the service life of charging modules to 8 years.
3. Medical and Precision Instruments
The 45 dB(A) low-noise design makes Sanyo Denki fans the first choice for medical equipment. For example, after a laser welding machine adopted these fans, the welding precision improved from ±0.1mm to ±0.08mm due to enhanced heat dissipation uniformity.

As shown in the table, Sanyo Denki fans lead comprehensively in three core indicators: static pressure, service life, and speed regulation response—with particularly significant advantages in high-resistance environments. Its technical barriers lie in aerodynamic simulation optimization and precision manufacturing processes. For example, blade angles are adjusted through CFD (Computational Fluid Dynamics) simulation, controlling the airflow uniformity error within 5%.
Conclusion
The high heat dissipation efficiency of Sanyo Denki fans is not a breakthrough in a single technology, but a systematic innovation integrating aerodynamic design, material processes, and intelligent control. From servers to medical equipment, and from industrial environments to outdoor scenarios, their efficient heat dissipation capabilities have been verified by extensive measured data and industry cases. For users pursuing performance and reliability, Sanyo Denki's San Ace series fans are an ideal choice for "maximizing heat dissipation efficiency."
