Heat transfer from housing to fluid

I've been struggling with what would seem a fairly simple heat transfer model.
I have a domain with a power loss. Above that is another domain which represents a housing, within which is a cooling channel. I've been trying to calculate the power dissipated to the fluid to correlate to another FEA package.
When I calculate dissipated power from temperature rise of the fluid, I get more power than what is introduced to the model from the power loss domain.
All walls are insulated, so all power should be going into the fluid minus the power to increase each component temperature.
I've increased mesh density but the overall result hasn't changed which leads me to believe the problem is more fundamental.
Can anyone share some insight?
