Liquid cooling? Cool...

And judging by this image and this image all the fuss about the new smaller motherbaord and the wasted space is moot.

Whoo! well worth a year's wait

Except from the processor, graphics card & liquid cooling in the high end model, is there anything else new?

Expect to see liquid on your floor

Dual 2GHz G5 + 20" Cinema Display

Looks like you (we) will have to wait a little longer for these babies. Estimated shipping date shows July. Translate that july 31st so most people may not get theirs until August.

I'm comparing the old 1.8/2.0 and the new 1.8/2.0 models. is there any difference between the two. (old and new) other the the lack of PCI-x for the old 1.8.

I'm tempted to get the model with the lower price.

8X SuperDrive, but that was pretty obvious since the last eMac update.

All in all a pretty basic upgrade. Gives you a bit more bang for your buck. Or were the old price points the same? The liquid cooling was, I suppose, a necessity to cool down the 2.5GHz model.

The old (middle of the line) dual 1.8 is more machine than the new (bottom of the line) dual 1.8. If you can grab one of the discounted old 1.8s for less than one of the new ones, then by all means, do that.

The "new" dual 2,0 looks to be identical to the "old" 2.0.

We need to combine all these threads.

Actually, the previous rev shipped with 8X superdrives for the last months..

Sorry, I couldn't respond because the board went down.

In any case, does anyone know how the fluid is circulated? I don't see a pump in the diagram.


Also, I thought this diagram was hilarious:



Compared to the PowerMac, the PC looks like some flunky grade school project.

I think that it is not strictly 'liquid cooled'...

It is just that Apple discovered 'heatpipes'.

Until I see a pump, I can't see how it is liquid cooled in the strictest sense of the description...

[mamamia]

My understanding was that the term "liquid cooled" merely described a process by which highly conductive liquid is used to help speed the transfer of heat away from the processor. I was unaware that it required a pump of any sort. Just because previous applications have used a pump does not, in my estimation, detract from the accuracy of apple charaterizing its process as liquid cooling.

That said, I would assume the liquid-filled pipe circulates by way of convection. I am open to being proven wrong, however.

But if the bottom one costs 500 bucks, can be upgraded to a 4Ghz CPU, has a PCI Express that I can stick an ATI X800 in, doesn't weigh 50 pounds, has loads of PCI slots and HD bays and when fully maxed out can kick the G5 DP and cost a third less, I'll take it.

If that Peecee was the one with the huge heat sinks we'd be laughing still.

Liquids are poor conductors if they aren’t actively circulated. If there’s no pump in the cooling system, then I assume that some form of convection is being utilized.

Maybe the cooling system uses an exotic MHD pump.

The bigger heat sink in the G5 probably allows its cooling fans to run slower, and thus quieter.

Blech. There's been more complaints about G5 noise on this forum than I can count. It's not whisper quiet. So if I had to choose between an expensive loud box and a cheap one I can tinker with then I'd pick the cheaper one. But it doesn't run OSX so that's a downfall....or Final Cut...but heck, it's good for games.
