Very good point. And, an extremely tempting experiment you have introduced
me/us to out of your mighty rucksack. Could prove to be the downfall of me,
buying a few more PC-104 (don't need be PC-104+, right?) Geode boards (I
already got one based on LX 800). Thank you :-)

Then, even without active cooling heat does flow more rapidly from a hotter
source to the ambient reservoir than from a cooler source. However, even if
you manage to get as cool as the cooler source by throwing in lightweight
active cooling you have barely arrived at the start line. Besides, you know
far far far better than I, final temperatures equal, heat dissipated thus
shows up on your electricity bill. (May be negligible for running just a
few such cores.) If given a choice I'd go with something that does not
generate the heat in the first place.
