5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your fans:
- Cleaning: Periodically clean the fan blades and housing to prevent dust buildup, which can impede airflow and increase noise. Use a soft brush or compressed air. Ensure the system is powered off before cleaning.
- Connection Check: Regularly inspect all cable connections (fan to controller, controller to motherboard, controller to PSU) to ensure they are secure. Loose connections can lead to intermittent operation or lighting issues.
- Hydraulic Bearing: The fans feature a hydraulic bearing designed for long life and quiet operation. It is self-lubricating and generally does not require user maintenance.
