Flow Simulation surface goal max temperature doesn't match surface max temperature

I have a simulation setup to model the temperature of a PCB as heat flows over a heatsink.

I have setup a surface goal on the PCB to converge when the max temperature is stable. The final converged temperature is around 40 DegC.  

When I create a surface plot on that same surface it shows temperatures upwards of 150 DegC.

Should these not match?
