Arcade machines generate significant heat due to prolonged usage and high-performance hardware. To prevent overheating and ensure smooth operation, various cooling systems are employed. Here are the most common types:

1. Passive Cooling: Relies on heat sinks and natural airflow to dissipate heat. Common in older or less powerful arcade machines.

2. Active Cooling: Uses fans to circulate air inside the cabinet. This is the most widely used method in modern arcades for efficient heat management.

3. Liquid Cooling: A high-end solution for premium arcade setups, using coolant to absorb and transfer heat away from critical components.

4. Ventilation Systems: Strategically placed vents and exhaust fans improve airflow, reducing heat buildup without additional cooling mechanisms.

5. Hybrid Systems: Combines passive and active cooling for optimal performance, often seen in custom or high-demand arcade machines.

Proper cooling extends the lifespan of arcade hardware and enhances gameplay stability. Choosing the right system depends on machine specifications, usage intensity, and environmental factors.
