Jones_Rush, how did you cool the power supply? Not many water-cooled PSUs about.
I bought a complete water cooled case, the water cooled PSU came with the case.
A word of caution: the modern faster processor might generate heat at a similar rate to the old one, but the die size is smaller, the power per unit area greater, so it's more of a challenge. Don't just assume that it's certain to work.
I didn't thought about that... Do you think there is any chance that the XP22000 won't be harder to cool than the T-bird 1.13Ghz ?.
If there's no pump and you're relying on convection to move water through the system, you'll get best results if the radiator is much higher than the items that heat the water. That way the loop will have hot water on one side and cold (therefore denser) water on the other.
Yep, that's the way it works in my case. Sort of. It uses the entire side of the case as a radiator.
If it's a "(truly!) 0db noise, passively cooled system" then presumably you've done something to the hard drive as well, right?
Yes. I bought a single platter 40GB Seagate Barracuda IV, which is very quiet, and installed it inside an acoustic case. It's impossible to hear it at idle. That's the only part which is not truly 0db silent though (and the monitor too. I can hear the 100hz bazz, just a little bit)
