Arcade machines, the heart of classic gaming, generate significant heat from their internal components. This heat, if not properly managed, can lead to hardware failure and reduced lifespan. The most common cooling systems are ingeniously simple yet effective, primarily relying on air circulation.

The most ubiquitous cooling method is the standard fan system. Most arcade cabinets, both vintage and modern, are equipped with one or more exhaust fans. These are typically mounted on the rear door or the top of the cabinet. Their primary job is to create a constant airflow, pulling cool air in from vents (often located at the bottom or sides) and expelling hot air out the back. This constant exchange prevents heat from building up around critical components like the power supply, monitor, and the game's PCB (Printed Circuit Board).

For the specific components themselves, passive cooling is often sufficient. Many arcade PCBs feature large, metallic heatsinks attached directly to hotter chips, such as the processor or voltage regulators. These heatsinks dissipate heat into the surrounding air without needing any moving parts. In some modern arcade machines that use standardized PC hardware, more advanced cooling solutions like dedicated CPU fans or even liquid cooling systems can be found, though these are less common in traditional cabinets.

Proper ventilation design is also a key part of the cooling system. The layout of the cabinet itself is crucial, with strategic vent holes allowing for optimal airflow. A lack of proper ventilation is a common culprit for overheating issues.

In summary, the arcade industry relies on a straightforward combination of exhaust fans for active cooling and heatsinks for passive cooling, all supported by a well-designed ventilated cabinet. This effective approach has kept countless machines running smoothly for decades.
