The "Temp" is the temperature of your CPU. The "Distance" is the amount of Degrees until it reaches your set danger zone (which is set to default for you currently) The "Thermal Status" tells you if the cpu is in any real danger, I cant tell you exactly what it says when you reach the danger temp zone because I havent seen it personally, but you should be able to tell if its trying to tell you that the CPU is overheating.
