Temperature goal plot is erratic.

I am trying to see what temperature a semiconductor reaches inside of a burn-in socket.  I have downward air impinging on a finned heat sink atop a burn-in socket inside which a semiconductor is generating heat.  I also have horizontal air travelling in a direction that is transverse to the fins and exits through a pressure opening at atmospheric pressure.  I have a persistent "vortex crosses pressure opening" warning.  I have tried enlarging the domain so that the vortex moves/disappears but have had no change in the temperature plot.  I have seen this warning in past simulations, but have not seen this type of curve behavior.  What could be responsible for this and how can I fix it to get a smoother temperature plot?

 

Thanks,

Juan
