I would give her some time to get used to the enclosure if you just got her. Sounds like the hot side may be a few degrees too hot, usually you want it around 90-92 (someone correct me if that's wrong). I would try moving the heat lamp closer to over the middle of the enclosure or piling more of your substrate over the heat pad side. I agree with subliminal, those heat pads can get way too hot if you don't regulate them. I had one make bad cracks on one of my 60 gal's bottom glass. So I stopped sticking them directly to the glass, just left them underneath the tanks.
