Ok. Flipper coil temp testing is done on RUSH. I did it on an LE and played for 2 hours straight (best score ~840 million, still barely understanding the game yet).
Overall, not bad. It has some interesting things going for it due to the way the software has what seemed like weird delays and holding some balls in the scoop in multiball rather than having them all out all the time in multiball. Playing it, I wonder if it isn't an attempt at temperature management. Even a flipper break of 3-5 seconds frequently enough can help keep flipper temps down. Whether intentional or not, I think it helped slow the heat advance on RUSH. Temps rose pretty slowly for the first ~40 minutes and flippers felt very good. In the second hour I was well into the fade zone, but the only things I noticed is more frequent bricking shots and I was having increasing trouble hitting the time machine ramp and making it with the right flipper. Just more rollbacks on the Time Machine ramp from the right flipper in the 2nd hour.
Generally speaking, the right flipper ran hotter than the left, except for one brief period of about 15 minutes where the left and right flip-flopped. Glancing down at the temp display while it was happening, I was surprised to see that in real time and paid attention to what I was doing to try to understand why. I think it was because I was trying to hit the right ramp repeatedly in a multiball, so I was working the left flipper more than usual. I also was using the left flipper more than I generally did to hit the time machine because the right flipper was having trouble with rollbacks. So it seemed that for this brief time those two extra tasks together in addition to normal flipper duty pushed the left flipper to be hotter than the right for the only time period in the 2 hours.
But overall, even though the peak temps put it on the moderate to severe category, it FELT like mild to moderate to me. And those breaks in the action where it's holding your ball while it's telling you or showing you something really helped dial back temps after a multiball.
Here's the data from the test. I wrote down temps every 5 minutes, but in the interest of clarity, I deleted temp labels (just the text, not the data) that were similar as the graph was too messy with all the temps on it. The graph data still reflects the temp, it's just not labeled if I deleted it to make room. All the peak temps are on the graph, though.
I'll be doing the "with Tibetan Breeze fans" 2 hour test as well, but that's honestly not as important as the stock temps because the story in every case is the fans bring the temps down a LOT and fade of any kind ceases to be a problem no matter how long you play. Might not have time to do it until next weekend as I'm still trying to catch up on GnR diverter/magnet coolers and godzilla magnet coolers, but I will do it soon and post an updated graph.
