In temperature chart its showing minimum temperature as -273, but initial temperature of component is 40 deg Celsius?
my guess is that you don't have appropriate BCs applied to your problem
make sure if you have heat in you also have heat out
remember that in thermal any face that doesn't have a BC is insulated
I sounds like you have heat out but no heat in. Your model is going to 0K, as expected.
