Heatsinkometer?

I usually model the sink with Finite Element Modelling and run a heat-flux flow model on it. You have to guess your interface-layers but it is quite good.
Setting up the models is pita though.

That's pretty cool man. Link? I love math.

FEMM was written for magnetics but has since gotten other modes as well. (Like thermal flow.)
