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

1. Passive Ventilation: Simple vents or grilles allow natural airflow, often used in older or low-power cabinets.

2. Exhaust Fans: Small fans expel hot air, commonly found in mid-range cabinets to maintain temperature.

3. Intake and Exhaust Fan Combos: Dual-fan systems optimize airflow by pulling in cool air and pushing out hot air.

4. Liquid Cooling: Rare but used in high-end or custom cabinets for superior heat dissipation.

5. Thermal Management Systems: Advanced setups with sensors and adjustable fans for precise temperature control.

Choosing the right system depends on cabinet size, hardware power, and environmental conditions. Proper ventilation extends component lifespan and enhances gaming performance.
