5. Maintenance
5.1 Cleaning Dust Filters
Regularly clean the dust filters (if present) to maintain optimal airflow and cooling performance. Dust filters are typically located at the front, top, and bottom of the case. Remove them and clean with compressed air or water (ensure they are completely dry before reinstallation).
5.2 Cleaning Exterior Surfaces
Wipe down the exterior surfaces, including the tempered glass panel, with a soft, damp cloth. Avoid abrasive cleaners that may scratch the finish or glass.
5.3 Internal Dust Removal
Periodically open the case and use compressed air to remove dust from internal components, especially CPU coolers, GPU heatsinks, and case fans. Ensure the system is powered off and unplugged before performing internal cleaning.
