Understanding and Applying goals in Flow Simulation

Hi everyone!

     I am aware that while in Flow Simulation you can assign goals via the "Goals" drop down on the left of the screen.  My question is though when assigning lets say a min, max, or average temperature, take your pick.  How do you relay to the program what you want the goal to be.  Lets say you are trying to heat up an enclosed computer unit to find the operating limit temperatures of a new microprocessor.  Would the best idea be to make multiple flow runs on the unit while heating up the wall temperature?  If so, my question is how do you tell the program, hey at XX degrees stop the simulation?  Hope this makes sense.  As always thanks so much for help and insight.
