I don't know of any new heat pipe technology, only old heat pipe
technology, which goes back to at least the 1960s (I have a hi-fi
amplifier from the 1980s or 1970s with one). But heat pipes typically
help heatsinks considerably, whether part of the heatsink is located
far from the CPU or everything is on top of it. Still you should check
comparative reviews (several models tested at once) to weed out badly
designed products.

Depends on what you mean by heat pipe technology. The flow of
condensate in heat pipes can be dependent on gravity, but a few of the
manufacturers have recently introduced "new technology" that allows
the device to be mounted in any position without detracting from the
efficiency.

you opinions on this matter.

XP-120 with the Recomended Panaflow fan. Excellent combination -
this keeps a well O/C Celeron D out of the stratosphere temp wise.
100% CPU load doing folding at home 38-39C. And was stated - they do
come with both brackets for the AMD and the Intel.

What you're comparing ultimately, is the difference in transfer
efficiency between pipe-to-fin and base/fin-to-fin.
I can only imagine that's gunna be anything appreciable for VERY large
heatsinks (I mean MUCH larger than your typical 92mm sink).
An upgrade wouldn't be worth it - but for a new unit where the cost
differential is inconsequential, you may as well go for the pipe
option.

the xp 120/90 kind of work like a condenser in a refrigeration or a/c
system. The base plate "boils" the coolant in and it transfers the heat to
the fins (condenser) where it is cooled and returns to a "liquid" state. if
you had a compressor, then it would really be an active cooling system!

What's your point? As several posters pointed out, all that does is
move the heat from the source to the radiator. It doesn't tell you
anything at all about the efficiency of the HS vs a conventional one
using conduction-convection rather than the heat-pipe system of
conduction-convection-conduction-convection.

And bottom-posting zealots, please keep your opinions to yourselves.
This controversy has caused countless flame wars without resolving
anything. As you can tell, I'm a bottom poster, like you, but it's
simply a matter of personal preference. Top posting prevents the need
to scroll all the way to the bottom of lengthy threads. Bottom
posting presents ideas in a more logical direction. Until there's
widespread agreement, to each his own.
