Fanless CPU cooling...

With 100w monsters (aka Prescott) on the horizon, will the innards of our PCs be a mass of heat pipes with the entire case acting as a heatsink?

That's a pretty cool article (all puns intended).

But I'm not sure I get your thoughts on that. Why would an article on running a TBredB 1700+ without a fan even be related to fears that the whole case of all new PCs would suddenly turn into a giant heatsink just because the CPU puts out over 100W?

I don't get that. :\

One of these days though I just might actually try my ideas for making my P4 2.6C run off of a passive heatsink. That's no where near as daring as completely fanless such as in your link, but it's still interesting I think.

interesting, but not a new idea...

I was however surprised with the low temps

Well, this setup was able to keep the overclocked 1700 alive, but 60 degrees is far from ideal.

In order to keep something with a bigger heat output cool, you would need to add more heatpipes or use a bigger heatsink or something.

Actually that was one thing that I wasn't too impressed by, was their heatsink. It was a huge aluminum monstrosity that looked rather inefficient. I bet a better design (probably a copper/aluminum hybrid) could be much smaller and get the same results and a better pure copper design could be smaller yet. (Or kept as the same size to work for hotter processors.)

They just need a nice lagre house fan to keep it cooler. I am sure that the temps would drop. The only problem I for see is that, with a closed case the temps would rise to much.

Yes but a large housefan defeats the point of it being a fanless system.

I thought that the point was that the heatsink would go on the outside of the case. (With a big label for the morons of the world that says "<font color=red>Warning</font color=red>, heat sink may be <font color=red>HOT</font color=red>!") Otherwise there would be no point. With the heatsink trapped inside of a case with no air flow it'd just be a thermal battery.
