Arcade machines generate significant heat due to prolonged use, making cooling fans essential for maintaining performance and longevity. The most common types of cooling fans used in arcade machines include:

1. Axial Fans: These are the most widely used fans in arcade machines. They move air parallel to the fan's axis, providing efficient airflow with low noise levels. Their compact design makes them ideal for space-constrained arcade cabinets.

2. Centrifugal Fans: Also known as blower fans, these are used when higher pressure airflow is needed. They draw air in and expel it perpendicular to the intake, making them suitable for systems requiring targeted cooling.

3. Squirrel Cage Fans: A subtype of centrifugal fans, these are often used in larger arcade machines or where quieter operation is preferred.

4. DC Brushless Fans: These are energy-efficient and durable, making them a popular choice for modern arcade machines. They operate quietly and have a longer lifespan compared to brushed fans.

Proper maintenance, such as regular cleaning and lubrication, ensures these fans remain effective. Choosing the right fan type depends on the arcade machine's size, heat output, and noise tolerance. Investing in quality cooling fans can prevent overheating and extend the machine's lifespan.
