4. Operating (Usage Notes)
- Blade Direction: Select the appropriate blade direction (forward/reverse) based on your airflow needs (intake/exhaust).
- Cable Routing: Ensure cables are routed away from fan blades to avoid obstruction.
- Speed Control: Use motherboard BIOS or software to adjust fan speed via PWM for optimal performance and noise levels.
- Lighting Control: For RGB versions, use compatible software (e.g., JONSBO RGB control software) to customize lighting effects.
5. Maintenance
- Cleaning: Use compressed air to remove dust from the fan blades and frame regularly.
6. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Fan not spinning | Loose power connection or incorrect voltage | Check the 4-Pin/3-Pin connector; ensure 12V DC power is supplied. |
| Excessive noise | Dust buildup or misaligned mounting | Clean fan blades; re-tighten mounting screws evenly. |
| RGB lighting not working | Faulty LED connection or incompatible header | Inspect the LED cable; confirm connection to a 5V 3-Pin ARGB header. |
