Question: Do you've ever heard about heat pipes?  I do not talk about
CoolerMaster's loud CPU coolers but solutions used in industry and
for notebooks.  Would be interesting to have a source where ordinary
customers can buy such heat pipes at a normal price.  AFAIK there is
a high priced desktop PC available in germany, nevertheless heat pipes
arn't that new.
