Troubleshooting
- Fan not spinning:
- Ensure the fan is correctly connected to a 5V power source.
- Verify that the power source is active and supplying 5V.
- Check for any physical obstructions preventing the blades from rotating freely.
- Excessive noise:
- Ensure the fan is securely mounted and not vibrating against other components or the chassis.
- Check for dust buildup on the fan blades, which can cause imbalance and increased noise.
- Verify that the anti-vibration mounts are correctly installed.
- Fan damaged after connection:
- If the fan was connected to a 12V power source, it is likely damaged due to overvoltage and requires replacement. This fan is strictly designed for 5V operation.
