    So I saw on google and I saw this "Quad" G5 with a massive graphics card inside:

    What kind of card is that? Looks super powerful and it also looks like it needs additional power.

    Looks like the Nvidia Quadro FX 4500. It does require a booster cable.

    Looks like thats sucker was water-cooled too. Was it available as a BTO?

    All dual 2.5, dual 2.7, and quad 2.5 GHz PowerMac G5s were liquid cooled. However, the systems used on the duals were rather unreliable and leaked often. You were then left with rebuilding the the liquid cooling or waiting until it fried the logic board, PSU, and corroded the case.

    The best grafics sard for a quad or a dual core G5 is a Radeon 1900 XT from Ati it was available seperatly in 2006.

    I know about the machines, I was asking about the video card itself.

    Oh ok. Looks like it is.

    Sorry, meant the CPUs. That is just a really large heat pipe to disperse heat over the heatsink.

    actually I would think there is liquid of sorts in those pipes, otherwise there would be no heat transfer from the GPU to the radiators.

    They're solid copper heatpipes. Copper is a very good conductor of heat. Liquid wouldn't move around without a pump.

    And if they used the same coolant as the LCS system cross your fingers it wouldn't leak and corrode everything!

    Thanks for that info.
    Now as to liquid not moving around without a pump, good thing nobody told that that to our old hot water tank that was heated with a coil in the wood stove.

    yup, as said before, fx4500, or a flashed gtx 7800 512mb ..

    very nice card, i also had one of these, and i also had the ati, the better card is the fx4500, gtx 7800. much quiter, and in some apps much faster..

    actually, i still have both.. lol.. though my gtx7800 still needs to be flashed..
    think i am starting a video card collection. :p nicest one i have is the 3dfxv5 5500 :)

    Most are solid. Those in the G5's video card are solid. I've cut them up for scrap copper in the past. Still quoting Wikipedia as a source doesn't make a good argument.

    Interesting. None of the ones I've seen to this day have been solid. None.

    If it's called a heat pipe, it's a pipe filled with a liquid. If it's solid, it's not a heat pipe.

    I quoted Wikipedia, as it explains the basic principle of heat pipes quite well, and as such makes an excellent argument. You might want to read the linked article.

    It's called a heatpipr because it pipes or moves away the heat like a pipe carrying away water or gas.

    Most are not solid. Having it solid defeats the entire purpose of a heat pipe in the first place. There is a liquid inside along with a 'wick' in a kind of vacuum, so it has a lower boiling point, which is why most times there is no liquid if you cut it open. Maybe the ones you took out were solid, but almost all of them have liquid.

    No. They are literally pipes. Check the article linked earlier, it explains the principle and construction.

    Or, if you for some reason distrust Wikipedia as a source, here's another one: Heat Pipe Basics and Demonstration
