Proper ventilation is crucial for arcade machines to prevent overheating, ensure reliable performance, and extend the lifespan of internal components like monitors, power supplies, and PCBs. The most common cabinet ventilation designs include passive ventilation, active exhaust systems, and strategic airflow management. Passive ventilation relies on vents or grilles placed at the bottom (intake) and top (exhaust) of the cabinet, allowing hot air to rise naturally and escape. This design is simple, cost-effective, and quiet, but may not suffice for high-power systems. Active ventilation uses exhaust fans, typically mounted at the top or back of the cabinet, to forcefully expel hot air. These fans create negative pressure, drawing in cooler air from the bottom vents. Some advanced setups incorporate intake fans or multiple exhaust fans for enhanced cooling. Another design involves dedicated cooling systems, such as internal fans directed at specific components like the monitor or power supply. Proper airflow paths are essential—ensuring vents are unobstructed and air moves smoothly from bottom to top. Regular maintenance, like cleaning dust from vents and fans, is also key to effective ventilation. By implementing these designs, arcade operators can maintain optimal temperatures and avoid hardware failures.
