Flipper fatigue is a real issue even with perfectly maintained assemblies.

I have seen it on games like Wizard of Oz and The Hobbit that have excessively long game times and continuous multi-ball modes.

Game times often exceed one hour and 15 minutes.

The Flipper coils get excessively hot almost too hot to touch or touch for very long.

Deep into these games the flippers do lose a lot of power.

I'm thinking of adding fans or heat sinks to the coils. Much like the heat sinks added to RC car motors.

But even with a heatsink you would still have to add a fan to cool off the heat sink.

I'm surprised that no one has put together a durable inexpensive mod to apply airflow over flipper coils.

I'd buy it for my WOZ and Hobbit.
I'm just too busy and too lazy to put something together right now.
