Umm, then maybe don't feed her so much? Who says you need to feed the snake every 5 days?
If you can't bring the cool side temp down, how about trying to reduce the heat of the hot side? Thermometers can easily be a couple degrees off (I have no idea what you're using to measure temps; I use a HerpStat 1, a high-end humidor digital thermometer, as well as an IR temp gun), so you're looking at potentially 92* on the hot side - which I would argue is much too hot.Cool side is about 84, hot side 90. I know the cool side is high but due to record heat, its not going down.
