*All 12V DC fans available with customization: wire length, connector, PWM, tachometer, FG signal, and IP protection.
1. Choose Size
Measure mounting space: 20mm to 120mm. Larger size moves more air at lower noise.
2. Define Airflow
High heat load → higher CFM or larger frame. For silent operation, oversize and reduce speed.
3. Select Features
PWM for speed control, tachometer for speed monitoring, IP54/IP68 for wet/dusty environments.
4. Bearing Type
Dual ball bearing: longer life (70k hrs), high temp. Sleeve bearing: lower cost, quieter for horizontal use.

FAQ of 12V DC Fan
What are the key advantages of using a Brushless DC (BLDC) fan?
As a professional dc brushless fan manufacturer, we utilize BLDC technology because it offers significantly higher efficiency, reduced electromagnetic interference (EMI), and a much longer lifespan (up to 70,000 hours) compared to brushed motors. They are the industry standard for reliable, continuous cooling in telecommunications and industrial cabinets.
How do I choose between a 12V and a 24V DC fan?
The choice depends entirely on your system’s power supply.
-
12 Volt DC axial fans are standard for automotive, consumer electronics, and smaller networking gear.
-
24V DC fans are more common in industrial automation and PLC control cabinets. Always ensure the voltage matches your power source to avoid motor burnout or insufficient RPM.
Can LINKWELL provide custom 12V DC fans (OEM/ODM)?
Yes. As a leading oem 12 volt dc axial fans manufacturer, we offer full customization. This includes custom wire lengths, specific connectors (2-pin, 3-pin PWM, 4-pin), and specialized ingress protection (IP55 or IP68) for outdoor or dusty environments.
What does the "92x92x25mm" size signify in fan specifications?
This refers to the outer dimensions of the fan housing. A 92x92x25mm dc axial fan is one of the most common industrial sizes. The first two numbers (92×92) represent the frame width and height, while the last (25mm) represents the thickness. When replacing a fan, always measure the outer frame, not the blades.
Are your 12V DC fans compliant with international safety standards?
As a high quality dc axial cooling fan manufacturer, all LINKWELL products are manufactured in ISO9001 certified facilities and comply with UL, CE, TUV, and RoHS standards, ensuring they meet global safety and environmental requirements for export.
Do you offer wholesale pricing for bulk orders?
Yes, we are a wholesale 12 volt dc axial fans manufacturer. We provide tiered pricing based on volume to support distributors and large-scale industrial projects. Contact our sales team for a formal quote based on your annual requirements.
