5. Maintenance

5.1. Cleaning Dust Filters

The H5 Flow RGB features removable dust filters on the front, top, and bottom. Regularly clean these filters to maintain optimal airflow and prevent dust buildup inside the case. To clean, gently slide out the filters, tap off loose dust, and rinse with water if necessary. Ensure filters are completely dry before reinstallation.

5.2. Cleaning Exterior and Interior

Use a soft, damp cloth to wipe down the exterior surfaces of the case. For the tempered glass panel, use a glass cleaner and a microfiber cloth to avoid streaks. For the interior, use compressed air to remove dust from components and hard-to-reach areas. Ensure the system is powered off and unplugged before cleaning the interior.

5.3. Fan Maintenance

Periodically check fan blades for dust accumulation. Use compressed air or a soft brush to clean the blades. If a fan becomes noisy or stops spinning, inspect its connection and consider replacement if necessary.
