Arcade machines require effective ventilation to prevent overheating and ensure smooth operation. The most common types of ventilation systems include:

1. Passive Ventilation: Uses vents or grilles to allow natural airflow, often found in older or simpler arcade cabinets.

2. Active Cooling with Fans: Incorporates exhaust or intake fans to force air circulation, commonly used in modern machines.

3. Heat Sinks: Metal components that absorb and dissipate heat, often paired with fans for better efficiency.

4. Liquid Cooling: Rare but used in high-performance or custom arcade setups for superior temperature control.

5. Combination Systems: Hybrid setups using both passive and active methods for balanced cooling.

Proper ventilation extends the lifespan of arcade machines and enhances gameplay by preventing thermal throttling. Regular maintenance, such as cleaning vents and replacing faulty fans, is essential for optimal performance.
