This link shows a picture of the G5 cooling system. It should put to rest the heat pipe theory as well as showing that the chips ARE cooled in parallel and not in series as depicted in Apple's oversimplified artist's conception drawing on their website.

Some info here. There is also a cooling thread.

Usually the pumps are pretty quiet. These pumps don't have to pump at high rates, just small volumes continuously.

Oh man would that be bad news if your computer sprung a leak!

That's what worries me. Even the best built cars can have radiator leaks, and there you have decades of experience in the design and implementation of liquid cooling systems.
Will the warranty cover you if your computer's water breaks?

For the first year I am sure it would but after that you are screwed.

Probably true. But antifreeze spreading around a computer's circuit board can't be a good thing in terms of short circuits and whatnot!

Yeah, but the water wouldn't really fall onto the motherboard. It would flow down into the bottom of the case or out of the case. It may splash against the motherboard, but it wouldn't pool on the motherboard. The power supply may be a concern depending on where it is and whether there is an opening from the CPU compartment to the power supply compartment.

Looks more like my Chevy. I'll believe it when I see it on Apple's site.

I'm still skeptical. It's the hose clamps. Wouldn't want them in anything I owned - they always leak eventually.

Well, if you own a car you already have them. That's exactly what scares me too. Water always finds a way to get where it wants, as any homeowner can attest. No seal is perfect forever, certainly not one subject to the temperature stresses of the interior of a computer!

Well the temperature stress inside a computer is not that bad, certainly when compared to a conbustion engine. I don't think that will be too much of an issue. Basically it will never top 100�C, which is not real hot. Besides unlike a car, the computer is not supposed to be able to run a subfreezing temperature, so that probably allowed to choose a much better tailored cooling liquid mixture.
I am curious to see the specs.

I'll definitely be waiting for the rev. B of that cooling unit. Anything that complicated is bound to have problems.

I'm sure they said the same thing about 9 fans.

I heard that the new G5 requires a coolant change every 100,000 miles or 5 years, whatever comes first.
