Default temperature drop at pressure outlet

Hi! I'm doing a conjugate heat transfer simulation with a pipe and a fluid. The fluid is expected to increase in temperature from inlet to outlet, which it does, but right before the outlet the temperature drastically decreases. Anyone have any idea why this happens?

I have defined a mass flow inlet with an inlet temperature, and a pressure outlet with no reverse flow.

thanks!!
