My idéa was that the heatpipe could spread the heat to a larger area and increase the contact surface so the wb could be less restrictive but still perform well. I find heatpipes kinda fascinating, mini phase change in a pipe. I guess that's the main reason why I wanted to build something with them.

But you're right, it would just mean more losses.

Btw. I saw someone using a heatpipe the way you described to cool a inconveniently located NB. I belive it was in some norwegian forum, can't find it now.
