I plan to cool my LOTR flipper coils by aluminium heat sinks if possible. Has anybody realized such a passive cooling system and can propose a concrete model and source for this sink? Is a heat sink sufficient for cooling of a coil? What do I have to take care of when installing a sink?
Alternatively, if this does not work, I would use a PC fan (which possibly is the more common approach), although this would mean that I have to take energy from somewhere. Which fan models (seize and voltage) do you use? Where do you get the energy from in the pinball?
Thank you and best regards
