Well, i finally grabbed a thermometer today. I put the probe on the inside of the tank, ontop of the UTH on the glass. All i can say is wow. The probe is currently reading 108*+ and it has been on for maybe 20 minutes. I definitely need to get a thermostat. Ambient temps are around 82* and the humidity 40-45% Dunno why is soo dry in there. Here's a pic .
