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

1. Passive Vents: Simple openings or grilles that allow natural airflow, often placed at the top or sides of the cabinet.

2. Exhaust Fans: Small electric fans mounted inside the cabinet to expel hot air, commonly found in modern arcade machines.

3. Intake Fans: Fans that draw cooler air into the cabinet, often paired with exhaust fans for better airflow.

4. Heat Sinks: Metal components attached to heat-generating parts (like power supplies) to dissipate heat passively.

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

Proper ventilation extends the lifespan of arcade machines and enhances gameplay reliability. Regular maintenance, such as cleaning vents and checking fan functionality, is essential for optimal performance.
