2. Core Performance Advantages
2.1 High Static Pressure High Speed Heat Dissipation
With a rated speed up to 18000 revolutions per minute, the 9GA0412P3J011 fan generates up to 535 Pa static pressure. It can penetrate dense heat sinks, narrow air ducts and compact cabinet internal structures, solving the heat dissipation difficulty of high-power chips in limited space. The airflow reaches 0.67 cubic meters per minute, balancing airflow volume and wind pressure to avoid local overheating of equipment.
2.2 PWM Adjustable Speed with Pulse Speed Feedback
This model integrates full PWM speed regulation function. Users can adjust fan operating speed in real time according to equipment internal temperature to reduce idle power consumption and running noise. The built-in pulse sensor outputs real-time rotational speed signal to the main control board, realizing closed-loop temperature monitoring and fault alarm when the fan stalls or speed drops abnormally.
2.3 Low Power Consumption & Long Service Life
Classified as SANYO DENKI Eco Products, the fan optimizes internal motor winding and blade aerodynamic design to reduce invalid power loss. The expected service life reaches 40000 hours under 60 ℃ working environment and 70000 hours under 40 ℃, effectively lowering equipment later maintenance and fan replacement frequency.
2.4 Wide Temperature Adaptability & Full Certification Support
The stable operating temperature range covers minus 20 degrees Celsius to plus 70 degrees Celsius, adapting to industrial low-temperature workshop and high-load continuous operation environment. The product obtains UL safety rating, CSA standard certification, EN standard certification and RoHS directive compliance, meeting export standards for electronic equipment in Europe, America and other regions.
3. Dimension & Structure Description
-
Overall outer frame size: 40mm length × 40mm width × 28mm thickness, standard square compact installation size, compatible with mainstream 4028 fan mounting holes of server and industrial equipment.
-
All plastic integrated molding frame, lightweight with overall mass only 53 grams, will not cause extra load to thin cabinet mounting brackets.
-
Non ribbed blade design, focusing on improving wind pressure performance, prioritizing heat dissipation efficiency for narrow channel heat dissipation scenes rather than low noise requirements.

5. Installation & Usage Notes
-
The fan operating voltage must be controlled within 10.8 V to 13.2 V DC. Long-term operation below or above the voltage range will shorten service life and cause abnormal speed fluctuation.
-
When using PWM speed control, match the control signal voltage level with the equipment main board to ensure normal speed adjustment and pulse signal output.
-
Avoid installing the fan in environment with heavy dust, oil mist or corrosive gas. If used in harsh working conditions, add external dust-proof and waterproof protection structure separately.
-
The service life data is tested under standard laboratory environment. Actual service life will decrease when operating continuously at the upper limit of 70 ℃ temperature.
-
Do not block the air inlet and outlet of the fan during installation, reserve sufficient air circulation space to guarantee the fan full airflow and static pressure performance.
