I'm trying to model the flow of air over a processor mounted on a cooling board for my ugrad thesis. Geometry was made in CATIA v5.19 in an assembly drawing, imported into ANSYS 14.5. It meshed fine, FLUENT will run the calculation fine.

My problem is that despite including the energy equation and declaring the processor an energy source in the cell zone conditions, there's no energy. I've tried laminar and viscous flows, different boundary conditions, 1000s of iterations, but there is no heat flux between inlet and outlet of the control volume, no change in temperature throughout the entire flow. Any suggestions on how to alleviate this problem would be GREATLY appreciated.
