Thermal simulation question

I am completely fresh and green to solidworks simulation.  I have watched a bunch of videos and have played around with setting up thermal simulations, but I have a question.  After I do a simulation with a circuit board and a heat sink the numbers I get back are around 1100 to 1600 Kelvin.  When doing the math this turns into around 1500 degree F.  Am I reading this chart wrong or does this sound like the error is in my setup.  Thanks in advance guys.
