Laminar Flow Reference Temperature

I'm trying to model a phase change in a bath of molten metal with some simple fluid flows. The laminar flow model requires a reference temperature but how do I pick this reference temperature? Should it be the melting point of the metal? Or rather the initial temperature?

The reference manual says this value is used to calculate density and viscosity but then why does changing the reference temperature drastically change my temperature field? Even when I tell the laminar flow node that density and viscosity come from the material this effect is still present.
