Arcade game machines are prone to overheating due to prolonged usage and high-performance hardware. To prevent this, several effective methods can be employed.

1. Proper Ventilation: Ensure the machine is placed in a well-ventilated area with ample space around it to allow airflow. Avoid enclosing it in tight spaces.

2. Cooling Fans: Install high-quality cooling fans inside the machine to dissipate heat efficiently. Regularly clean the fans to prevent dust buildup.

3. Heat Sinks: Attach heat sinks to critical components like CPUs and GPUs to absorb and disperse excess heat.

4. Regular Maintenance: Clean the internal components, including circuit boards and vents, to avoid dust accumulation, which can trap heat.

5. Temperature Monitoring: Use thermal sensors to monitor internal temperatures and shut down the machine if it exceeds safe limits.

By implementing these methods, arcade game machines can operate smoothly and avoid overheating-related issues.
