I've never tried watercooling but I imagine it can be done with two waterblocks, some pipes, and a heatsink that is cooled by the PSU fan. What do you guys think?

It is my understanding that a heatpipe involves the use of some sort of absorbant material on the pipe walls for the recondensed liquid to get drawn back to the evaporation area.

Here's a page explaining it, click

Well, if you intend it to operate without a pump, maybe you better add 2 one-way valves so the water will circulate by expanding/contracting.

Drawbacks are of coz slow circulation and you really need the water to heat up(a bit too much for my flava) to use the expanding phase. For a non-extreme machine it would be utterly silent and cool...... :beer:

gone_fishin you are pretty much right, but just to clearify something. A heatpipe is a device that has a liquid(normally a high pressure gas that was condensed into a liquid by pressure) and when heat is added to the bottom of the heat pipe, the fluid evaporates into vapors that collect on the top and sides(like ganefishin said) and condense and crawl back down to the bottom where the cycle restarts. What you guys were talking about was a pumpless watercooling system like this onehere . These type of systems are really hard to construct and may not be worth making. Heatpipes on the other hand can also be hard to construct but are easier to construct and if you construct it well and big enuff you could run it without a fan, of course you have to remember that the part creating the heat (cpu in this case) has to be the lowest part of the system, and the cooling radiator tend to work good in a horizontal possitions.

hope this helps

*edit* rereading that article I notice they do mention evaporation of the liquid, so it could be a heatpipe, but if its just expanding and not evaporating its not a heat pipe.
