Quoted from PinMonk:Godzilla is a slow build for coil temps, more like LZ or Star Wars, so you probably won't notice fade in an hour. But once you get there, fade is easy to tell apart from coil stop issues. Coil stops problems are there from the beginning of play if they're bad. Faded coils were fine when you start, but get bad once they heat up after a longer session. Then when you let them cool off and come back later, they're fine again. Coil stop issues aren't like that.
Yeah, the AIQ when the coil stops were starting to give, shots were still makeable early on in the gameplay, but more noticeable later on with light fade, i guess. I replaced the stops first, and it improved shots at around the timeframe I was starting to see bigger issues, then around at the 1hour mark I noticed the bigger fade issue (usually when the shots were getting a PITA i stopped playing so never really made it critical heat). The fans helped us get to pretty much non-stop playing afterwards.
Later when the pin gets to a nice spot at home, we'll be getting more gametime, so we'll see how it does 1-2 hours of gametime.
