More G5 Liquid Cooling Photos

Looks very sophisticated.

However, what's really the big deal? I find it hard to see how they could fit that kind of system into a PowerBook which is the only exciting conclusion one can draw from this system.

According to some resellers in my region (belgium) they expect them end june, some say end of july, and some just leave it to "somewhere in july"

hope they ship soon, that I can admire that liquid cooled beauty on my desk ;)
 
cooling system

Techseekers.net posted a few photos from the recently released PowerMac G5 with Liquid Cooling.

Various liquid cooling diagrams/product shots have been circulating, but these new photos appear to be taken of an actual production PowerMac G5.

I've seen this weekend in a BEST BUY ad SONY has already jumped on the liquid cooling system bandwagon.

Another Apple innovation? Stock LCS.

I.
 
Or they're the first computer company where air cooling was not technically/economically feasible for their processors.
 
Pressure Release Valve?

If you look at the third picture in the set (the first one showing the
pipes going to/from one of the CPU's). In the foreground there appears
to be a pressure release valve (it comes right out of the radiator
and has a black cap).

Let's hope you get some warning before the coolant start's spewing out
of that. To be fair it looks like it is as far away from the logic board as
possible (not sure what is above it). I'm also sure that under any kind
of normal operation it won't come close to needing it. Also I'm sure the
environment that a computer lives in is _much_ softer than your average
car.

The only thing I can think of that would cause problems is 'dust collection'
I could see the radiator collecting a 1/4 inch of dust - which for what
ever reason never really seems to happen to car radiators (perhaps it's
that 60mph wind).

I agree! That's the first thing I thought of when I saw that close-up of the connections. And, I owned a FORD once, so I don't want to be Fixing-Or-Repairing-Daily (or insert your own car joke) my G5 :).

Seriously, I guess this isn't to worrisome, it's being done elsewhere too ?? but I'm not sure if I want to buy now, or wait on you guys! :p
 
cars cars cars blah blah blah

why are cars always brought up when there's talk about computers?! i'm getting sick of it! it's not like i have anything against cars, but computers and cars aren't the same thing.

also, i'm not referring only to your post, but all the post on the net..
 
what is the thermal capacity?

My guess is that this system has a lot of capability to scale to a much higher thermal load if required, say, for a 3+ Ghz in the future. Apple saw the writing on the wall, and decided to get this figured out before it becomes a major hurdle. Fans would have worked, but, this water cooled system is probably much quieter.
 
Who Cares?

So how many stories are we going to see on MacRumors about pictures / diagrams / hieroglyphs of the G5's liquid cooling?

Big deal.

I guess news is slow leading up to WWDC.

Ya, I agree here. I am getting really tiered if Liquid cooling news....

I'm in the UK - I ordered a dual 2.5 about an hour after they were announced. My ship date is "On or before 2/8/2004".
 
Any one noticed

That it seems to be on the old motherboard. I thought the new one was going to be shorter, and not really stick out on the left side. So this looks like a present day G5 with the prototype cooling system. I think it might be a little different than this when we get the actually product.
 
Liquid cooling is nothing new..

Liquid cooling has been around for a number of years. It is hardly an "Apple Innovation"
 
Looking at the pictures, it feels like if I touch it, my hands will get dirty with grease and oil :)
 
Doubtful

I doubt its a PRV. More like the coolant pressurize connection (where they charge the system, much like an auto's refrigerant). There is no need to have a pressure relief system on this unit. If so, we'd have to require some exhaust vent. Is it me or is this getting way outta hand?

Is this REALLY the actual production cooler? I have to admit, those crimp-clamps do not reassure me of a "reliable" system.

If this is needed to a dual 2.5ghz system, will we get a "dorm-fridge" if Apple makes a Quad +3.0ghz system?
 
get used to it

True. You HAVE to have a license to operate a car. (I really wish you had to have a license to use a computer!).

But why complain? Where else do you see a cooling system like this (in other than a refridgerator, Air Conditioner, or automobile)?

And since a loaded G5 Dual 2.5ghz is priced with a used car, its only logical to compare Apples to Autos.

/would you like some cheese with that whine?
 
So, where are those rumors for WWDC '04? Enough of the liquid cooling pics. Give me some rumors that I can care about.
 
Apple innovation - not! Sony was first.

I think you mean that Apple is jumping on the bandwagon - the Sony RA710G/RA810G was announced about a month before the G5 upgrade.

Sony is shipping now (some online stores say "in stock"...), the new G5 has yet to ship.

SONY DESKTOP PC SPORTS NEW DESIGN FOR CUTTING EDGE PERFORMANCE

SAN DIEGO, May 11, 2004 - What stands out about Sony's new desktop computer is what's not there. The hole in the side of the VAIO R series desktop represents a generational leap in cooling and acoustic technology, while leaving room for top-level performance.


The sophisticated black tower not only looks cool but acts cool. The dynamic airflow design, liquid cooled heat exchanger and efficient fans allow the unit to take on high-intensity processing without breaking a sweat. Also with air intake in the middle of the PC instead of the front, the noise level is drastically reduced, allowing for AV enjoyment without the interference of internal noise.

Does Apple give priority to American customers over foreign?

I ordered my 2.5 three days after the release, and I also have yet to see the order go to 2-day shipping. It's still listed as ground shipping. :(

I second, third, or fourth that......depending on how many get in before me. I keep coming back to macrumors.com and thinking that there are no new stories for the day, but find that it's actually a NEW G5 cooling article I'm looking at. man these are Page 2, or macbytes articles AT BEST. seriously not macrumors worthy.
 
I must confess to feeling a little apprehensive towards this liquid cooling system. I mean - overclockers are born tinkerers - they are used to (and in fact in most cases probably enjoy) having a system under constant maintenance.

I on the other hand, cannot be bothered these days with tinkering and would much rather get on with some work. I'm buying the DP2.5 purely for audio work and don't want to have to get it serviced periodically or risk it springing a leak or worry that it might be about to explode at any second.

I'm wondering should I have just bought a dual 2Ghz at the new price. :confused:

Well, it's hard to imagine the water/glycol in that system getting anywhere close to boiling.
