    I've used a single 80mm fan tie strapped to the wires blowing air into the flipper coils. I used this on batman forever where the flippers tended to get worse the longer the game was played. This solved the problems utterly.

    Quoted from Wolfmarsh:

    I didn't realize this was actually a thing. What's the reason for the loss of power? Is it the coil heating up, expanding, and squeezing the sleeve/plunger harder?

    Sterns 5020 coils are strong but small and can hear up even with eos working correctly. I've experienced it with lotr, batman forever, acdc (my first one not this one), and 24. The games that use 5032 coils seem better but those are weaker coils.

    Quoted from radium:

    Seems like a single DC blower might be enough to blow across both coils. Should be quiet enough depending which one is used.

    I used a 120mm pc fan ties strapped to the wires pointing at both coils and it did its job well

    Quoted from rcbrown316:

    ADDED FANS. NO LUCK. SAME ISSUE THOUGH NOW I am thinking it's more intermittent than heat related. I will check for loose connections in the wiring and on the pcb. a few have mentioned faulty transistors. also of not the flippers assy's both had the eos switched removed when I got it. i'm wondering if this has damaged the electronics

    Maybe you should start a tech thread where you can clearly describe the problem, list the game, etc
