More G5 Liquid Cooling Photos [Archive]

MacRumors

Techseekers.net posted (http://techseekers.net/modules.php?name=News&file=article&sid=3927) a few photos from the recently released PowerMac G5 with Liquid Cooling.

Various liquid cooling diagrams/product shots (http://www.macrumors.com/pages/2004/06/20040614141403.shtml) have been circulating, but these new photos appear to be taken of an actual production PowerMac G5.

The 2.5GHz (Liquid Cooled) PowerMac G5 is not due for shipping until late July.

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 ;)

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

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

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.

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.

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?

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.

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.

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:

Ditto - having the same feeling - why did I wait for the past 6 months. Yes, we can and will use all of the CPU available for all of those hungry audio plug-ins, but maybe a 2G might be a better choice. But fellow ProTools folks had to do a lot to get them to work cleanly, so I thought Rev B would be better; but an LCS doesn't smell of a Rev B. Sigh.

Or, maybe I'm just too woried... :confused: Buy AppleCare, and move on?

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 when you buy the first mass produced device after revision there is an element of risk, but you are also on the cutting edge......
honestly the amount of liquid in there is maybe a cup? probably much less.... think of how small that unit really is. it's also not like a car with rubber hoses and left out in harsh weather. i would bet the odds of this exploding on you are much less than some piece of equipment if your studio causing an electrical fire, or a meteor falling on your roof.

for a/v work it will be interesting to see how this machine at full work load compares to the 2x2.0 at full load (noise-wise). i would hope it makes less noise than its slower sibling. there are speed controls on all the fans, as well as the coolant pump.... so at idle you should nap fine if nothing else...

johnpaul191

Jun 21, 2004, 12:26 PM

I dunno....it looks pretty 'un-Apple-like' to me, so I'm wondering if the photos aren't fake. I know that they *are* going with liquid cooling on this generation, but just speculating that the pictures themselves could be concocted.

Also, as someone else pointed out, wasn't the motherboard supposed to be smaller on the new systems, too? This one (in the pics) looks the same size as before....

Craig

that smaller motherboard was shown in the pictures in the tech manual that was "leaked". those pictures do not have the liquid cooling, nor do they match the 2 new G5s that were released. there are pictures of the non-liquid cooled machines and they don't match that manual either (RAM placement etc).
in this picture the liquid cooling system seems to be very modular. it really looks like the unit is dropped on the new motherboard in place of the heatsinks. that makes me feel better about it in the sense that they can easily revise it, or use the same case for all the G5s (saves everyone money).

someone mentioned how that makes you really think the G5 powerbook really is far off..... i also would think the liquid cooled X-Serve is nowhere close? i can only guess till there is some advancement, those machine will lag in chip speed. i guess liquid laptops exist, at least in test enviroments. if they can make them work, they will easily get the X-serve hopping. maybe next rev chips will run cooler at the slower speeds, so it'll work out.

That looks like a turbo charged hot rod. The picture in the new service manual must be the new dual 2.5's--one big heat plate or cover instead of 2 close together.

No it's not.. the pics in that 'leaked' tech manual are not pictures from the updated powermacs (how many times has that been reported? I've lost count)
and yes, the new powermacs have one big heatsink, with a small crease in the middle. That's all there is in terms of resemblance with the 'leaked' tech manuals

Yes, I'm wondering also, with all the announcements lately - what has Steve got left to announce? We've had the new PowerMacs (one with the 1st ever Liquid Cooling System ever on a Mac), Airport Express, Remote Desktop 2.0, iTunes 4.6 with Airtunes, iPod your BMW, all in the last few weeks, and usually Steve likes to have something to WOW us with. Could the leaked manual be of some other new type of computer? I know that new LCD monitors are expected shortly, but that isn't usually the kind of stuff that Steve brings out as the next big thing. Steve has got to have something else up his turtleneck - what could it be?

I know what I'll be doing with my dual 2.5. Overclocking it! This system already has water cooling installed. how cool is that!. Or, if overclockers want to chill it down further, half the work is already done since the piping is already in place. All that would have to be done is to install a compressor-type mod and replace the water-glycol mixture with a refrigerant.
