This customer had an arcade game that was shutting off randomly during business hours.

This arcade game is a PC based game.  After reviewing the situation, it became evident that the amount of dust inside the cabinet was causing the PC to overheat and shut down.  Unfortunately, a thorough cleaning was not enough.  The dust and heat had already damaged the main processor fan.  The second hand of a clock was spinning faster than the CPU fan.

The challenge was finding a replacement fan as this PC was not your typical name brand computer.

Thanks to Google, the fan was found in China, shipped over, and the game is still functioning well.
