Proper ventilation is crucial for arcade machines to prevent overheating and ensure optimal performance. The most common cabinet ventilation solutions include:

1. Exhaust Fans: Placed at the top or rear of the cabinet, these fans expel hot air, creating negative pressure to draw in cooler air from vents or gaps.

2. Intake Fans: Positioned near the bottom or sides, these fans pull fresh air into the cabinet, improving airflow circulation.

3. Passive Vents: Strategically placed vents allow natural airflow without fans, often used alongside active cooling systems.

4. Dual Fan Systems: Combining intake and exhaust fans maximizes airflow, effectively regulating temperature.

5. Air Filters: Attached to vents or fans, filters prevent dust buildup, which can obstruct airflow and damage components.

For best results, ensure fans are quiet yet powerful (e.g., 120mm PC case fans) and position vents to avoid direct dust exposure. Regular maintenance, like cleaning filters and checking fan functionality, prolongs your arcade machine's lifespan.
