Product Information
Full details
The X-Fan RDH1225S2 is an industrial-grade 24V DC axial fan designed for engineers, system integrators, and hobbyists who require reliable, consistent airflow for electronic components or equipment enclosures. Its brushless motor design ensures longevity and efficient performance, though users should note that as a sleeve bearing component, it is best suited for upright or horizontal mounting rather than extreme-vibration environments.

FAQs
Can this fan run on 12V?
No, this is a 24V DC fan. Running it on 12V will result in significantly reduced performance or failure to start.
Is the RDH1225S2 waterproof?
No, this fan is not rated for water or moisture exposure. It is intended for dry, indoor electronics environments.
How long is the service life of the sleeve bearing?
Sleeve bearings are rated for standard operation life, provided they are kept clean and operated within the recommended temperature range.
Does this fan include a speed sensor (tachometer)?
The RDH1225S2 is a standard axial fan; please refer to your specific batch labeling to confirm if your model includes a wire for RPM monitoring.
Can I mount this fan horizontally?
Yes, but be aware that sleeve bearings perform best when mounted vertically. Horizontal mounting may result in a slightly shorter lifespan due to lubricant migration.
Troubleshooting
Fan does not spin upon power-up
Verify the power source is outputting a full 24V DC and check that the wiring polarity matches the fan specification label.
Excessive noise during operation
Check for obstructions near the blades or ensure the fan housing is securely mounted; vibrations in the chassis can amplify mechanical noise.
Fan speed fluctuates
Check the power supply for voltage drops or ensure the fan is not being throttled by an external speed controller that is incompatible with the brushless motor.
Pros and Cons
Pros
- Efficient brushless motor operation
- Reliable cooling performance for sensitive electronics
- Standardized size for broad compatibility
- Quiet operation due to sleeve bearing construction
Cons
- Sleeve bearings are less durable in high-vibration scenarios
- Requires a steady 24V DC power source
- Not intended for high-heat industrial exhaust environments
Setup, Compatibility & Care
To install the RDH1225S2, ensure your power supply provides a stable 24V DC output; connecting to higher voltages will cause immediate damage. The fan mounting holes are compatible with standard 120mm brackets. For care, avoid exposing the fan to excessive dust or debris, which can accumulate on the blades and cause imbalance. Periodically use compressed air to clear the blades. Ensure that the polarity is correct during wiring, as reversing the positive and negative leads may damage the internal circuitry of the brushless motor.
