AppleInsider was the first to get interior shots of Apple's new liquid cooling system. Now they got their hands on some diagrams along with descriptions of the liquid cooling system components.
Last week Apple Computer, Inc. introduced its most powerful Power Mac model to date, which sports two 2.5GHz G5 processors and a nifty liquid cooling system (LCS). Curiosity surrounding the new LCS is running high as Apple officials have recently reiterated warnings that other G5 products from the company remain a long-shot due to G5 heat issues.
Aiding some of the curiosity, sources have recently provided AppleInsider with side and rear-view diagrams of the new Apple LCS, which detail some of its many components. In a recently published self-training course on the new line of Power Mac G5 computers, Apple confirms that all models feature IBM's 970FX PowerPC G5 processor.

- * Now the drivers should work a LOT better on laptops.
* Fixed FireGL card support, now it has full CP support and fully working OGL.
* Changed the installer graphics.
* Added a new option in the installer to select a faster OLG driver instead of
just using the latest one, this driver runs Counter Strike like butter.
Important note: The special OGL driver will NOT work on x800 cards.
Many thanks to NGO for their input, this was their idea.
* The package keeps growing in size, the drivers will keep being distributed in
compressed CAB format to save some bandwidth, it must be decompressed using one
of these tools (latest version): WinAce, WinRAR or WinZip. Then run the extracted
file to start installation of the drivers.
only took one hour to install.........
Unless they come up with a way to cool these beasts down, water or refrig is going to be the
way to do it. The internal case temps are getting out of hand. 7200 and 10,000 RPM drives,
Raid arrays, video cards with heat sinks and fans, CPU and chipset fans. Heck, you could use
the inside of a case to roast hot dogs.........hummmmm......there's an idea for a case mod
AMDzone comments:
John Liscomb sent in the link to this page that shows a very good picture of the PowerMac G5 cooling system. It seems that there is not only liquid cooling that takes advantage of a good sized radiator, but there is also dual copper heatpipe cooling used to cool the underside of the motherboard. In fact it is taking Apple two rare as hens teeth cooling methods. You don't usually find heatpipes in desktops. You find them in small form factors, and laptops, and some high end air cooling solutions. I've never seen a desktop design that required liquid cooling on the CPU, and heatpipe cooling below the motherboard. Comments? I don't think this bodes well for quantity shipments of this 2.0GHz overclocked to 2.5GHz PowerMac. Well it isn't like Apple would ship many anyway at 2% marketshare. It is disturbing that so much trouble is being had at 90nm. We shall see shortly, perhaps even before these PowerMacs ship what AMD has done at 90nm. With their close relationship with IBM it will be interesting.
A basic idea can be seen
