I read the review on the Zalman TNN 300 on Bit-Tech and I've got to say it would be nice to have a completly silent PC. Although is silence worth that sticker price? I don't know but I know that when I had my comptuer in my room, the noise got really anoying when I was trying to sleep.

Now I was thinking with heat pipes being so expensive, what if you mixed a water cooling system with a heat pipe system. Instead of having a fan to cool your water use heat pipes. Has this been done and would it be possible?

Let me get this straight- you want to use heat pipes instead of a fan to cool a WC system.

Hmm. That sounds somewhat... silly. (and a touch redundant)
A heatpipe (like the one used in a heatsink.) is meant to improve the efficiency of conduction of the heat-source to a point away from said heat-source when compared to metal-on-metal contact. The coolant in the heatpipe then releases the heat it's holding into into radiator fins which then releases it into moving air. Unless the radiator section is massive and you either need relatively low-draw components or a decent amount of air being pushed through through the fins.

What you want is one of those passive tower radiators, or perhaps if you have the space for it (and your unit is not going anywhere) a bong-style cooler.

Now pumping fluid through a heatpipe type heatsink- is a decent idea.
(One I'd like to see from more than Thermal*bake [I mean take... not.]


Additional Note:
I'm going to turn a useless-defective (The heatpipes had nothing in them --and I was wondering why I was getting 69*C on an under(clocked/volted) 2.4C Northy ) XP90C into a real monster in an attempt to make a proof-of-concept (Larger diameter pipes and use of a wire brush to score the pipes [turbulence] hybrid cooler that's superior to thermaltack's Volcano heat-exchanger.

Good Point, if you think about it, likely the most expensive part of the Zalman case is that the case its self has to be engineered as a giant heat sinc. The real heat solution in the future will come from more efficiant CPU architecture, such as the Dothan style Pentium M processors.
