Reported Chamber Temperature is a little optimistic

The temperatures reported from my X1 Carbon showed the following when I powered up the printer this morning. An extruder temperature of 7, a bed temperature of 8, and a chamber temperature of 13. Is there any way to adjust this via an offset to get an accurate reading of the chamber temperature?

I set the bed to 70 and Aux fan to 50% for half an hour to warm everything up before I just the printer in the winter (southern hemisphere).
