Quoted from mrgregb123:After going back and forth between getting better coils or installing fans, I'm going the fan route. The posts in this group talk about using PC fans but don't go into how to connect them? What kind of PC fans are you using, 4 pin small connector? Is there an adapter needed or do these plug right in somewhere?
Go with the APB medium strength coils. Just installed mine yesterday after years of flipper strength fade and they're fantastic, no more fade and I'm able to make the ring shot all the time. You won't regret it.
