Micro Fan Specs Compared
Physical dimensions
The WINSINN 30mm fan measures 30mm by 10mm, providing a slightly larger footprint than the 25mm model. Product A is 1.18 inches wide and 1.18 inches long. Product B measures 25mm by 10mm, with a width and length of 0.98 inches. Both fans share the same thickness of 0.39 inches. The 30mm fan is heavier at 3.52 ounces, while the 25mm fan is lighter. You should choose the 30mm fan if your mounting area allows for the extra width. The 25mm fan fits into tighter spaces, such as small 3D printer extruders or narrow router vents. Size matters when fitting into compact electronic enclosures.
Airflow performance
Airflow determines how much air the fan moves. The 30mm fan delivers 3.46 CFM. The 25mm fan moves 1.35 CFM. The larger fan moves more than double the air of the smaller one. This makes the 30mm model better for cooling components that generate significant heat. The 25mm fan is suitable for low-heat devices like Raspberry Pi or TV boxes. If you need to cool a densely packed computer system, the higher airflow of the 30mm fan is crucial. The 25mm fan sacrifices volume for a smaller profile. Choose based on the heat load of your target device.
Acoustic output
Noise levels differ significantly between the two models. The 30mm fan operates at 28 dBA. The 25mm fan runs at 18.8 dBA. The smaller fan is much quieter, likely due to its lower speed and smaller blade area. The 30mm fan spins at 9000 RPM, while the 25mm fan spins at 7000 RPM. If you are building a system for a quiet room or a bedroom, the 25mm fan is the better choice. The 30mm fan is louder, which might be noticeable in sensitive environments. However, the noise difference may be acceptable for industrial or server applications where cooling priority is higher.
Static pressure
Static pressure indicates how well a fan pushes air through resistive surfaces like heatsinks or filters. The 30mm fan produces 0.23 in H₂O. The 25mm fan produces 2.32 mm H₂O. These units are different, so direct comparison requires conversion. One inch of water is approximately 25.4 millimeters. Therefore, the 30mm fan generates roughly 5.85 mm H₂O. This means the 30mm fan has higher static pressure in standard units. It is better suited for pushing air through dense heatsinks. The 25mm fan is optimized for free air movement in open spaces.
Visual features
Lighting is a key differentiator. The 25mm fan includes RGB lighting, providing colorful illumination when active. This is useful for aesthetic builds or visual status indicators. The 30mm fan is black and does not feature RGB lighting. It is a functional-only component. If you are building a 3D printer with visible electronics or a small PC case where aesthetics matter, the RGB feature adds value. The 30mm fan is better for hidden installations or industrial equipment where light is unnecessary. Choose the RGB model if visual appeal is part of your requirement.
Choose your WINSINN micro fan
Need high airflow for compact systems
The 30mm model delivers 3.46 CFM airflow at 9000 RPM. This higher speed and larger surface area move more air than the smaller option. It suits computer systems or automotive electronics where maximum cooling is required in a tight space.
Want silent operation with RGB lighting
This 25mm fan operates at just 18.8 dBA, significantly quieter than the 30mm version. It also features RGB lighting for visual appeal. The 24V rating and hydraulic bearing ensure stable, low-noise performance for 3D printers or small electronics.
Need static pressure for dense filters
Although it moves less air, this fan generates 2.32 mmH2O of static pressure. This is much higher than the 30mm model's 0.23 in H2O. It is better suited for pushing air through resistive surfaces like dense filters or heatsinks.

Frequently asked questions
Does the 30mm fan have RGB lighting?
No, it does not. The WINSINN 30mm 12V Hydraulic Bearing Fan features a black finish without any lighting elements. It uses a 2-pin connector for power and speed control only. If you need visual effects, you should consider the 25mm model instead, which includes RGB capabilities.
Can I use the 25mm fan with a 12V power supply?
It is not recommended. The WINSINN 25mm Micro RGB Fan is designed for 24V operation. Using it with a 12V source may result in insufficient speed or failure to start. The 30mm model is explicitly rated for 12V, making it the safer choice for standard 12V systems.
What type of bearing do both fans use?
Both models use hydraulic bearings. This bearing type provides smooth rotation and reduces noise during operation. Hydraulic bearings are known for durability and consistent performance over time, making them suitable for continuous use in compact cooling applications without requiring frequent maintenance.
Which fan is better for a 3D printer extruder?
The 25mm Micro RGB Fan is better suited for this task. It is specifically designed for 24V 3D printer extruder cooling. Its smaller 25mm size fits tighter spaces around extruder components, while the 24V power requirement matches typical printer electronics. The 30mm model is too large and uses the wrong voltage.
How thick are these micro fans?
Both fans have the same thickness. The WINSINN 30mm fan is 10mm thick, as indicated by its 30x10mm dimension. The 25mm fan is also 10mm thick. This slim profile allows them to fit into very tight spaces where standard fan thicknesses would not work.
Do these fans come with RGB controllers?
The provided data does not mention any included controllers. The 25mm fan has RGB lighting, but no specific controller or hub is listed in its specifications. You may need to purchase a separate RGB controller or hub to manage the lighting effects independently from the fan speed.
