- pvera, on 10/12/2007, -0/+5Also note how that guy probably voided his warranty on that ultra-expensive rig.
- LawrenceDudley, on 10/12/2007, -0/+2That thing is kinda space-age. If I didn't know it was cooling for a G5, I would have thought it was part of a car engine :-P
To be honest though, the G5's aren't all that loud. If they're idling, or just sitting there playing a dvd or iTunes or whatever, then yes, they're quiet. When you're doing 3D renders on them, like I was, using Cinema 4D, they're LOUD, and it's unbelievable how hot those things get: The hairdryer in Switzerland broke, so I stuck the Quad on doing a render, and stuck my head behind the exhaust fans at the back. Putting your hand up close to them is actually painful, and even three-four feet away you can still feel the heat.
Crazy machines, but certainly something a LOT of people want ;-) - D4r7h3v1l, on 10/12/2007, -0/+2All I see is that he took apart the computer. When did he take apart the processor (as the title says)?
- ep0niks, on 10/12/2007, -0/+1Holy guacamole.
4 CPU in a ATX tower.. i wonder if Intel will be able to provide small chips like that because a Quad Xeon Tower is big as a 2 story house (3U or 4U) - ggriffit, on 10/12/2007, -0/+1Wow...that took a lot of guts to open it that far!
Well done! This is very cool. Even the bottom of the chips have copper plates for extra cooling.
Just think...All that cooling and processing power and almost no noise at all. Well done Apple. - neocitron, on 10/12/2007, -0/+1Apple engineers are probably the most tortured humans on earth... that's a great feat to get all that crap inside that G5 case.
- tillemetry, on 10/12/2007, -0/+1Interesting that they have an automotive subcontractor (Delphi) doing the cooling system. Wonder if they got a 5 year warranty on it? Shouldn't have to worry about potholes.
- slackerdave, on 10/12/2007, -0/+1I got a quad a month ago and can confirm that it's like a blow-drier set on low when it has a load on it. Not loud at at. Just a lot of heat coming out the back. I'm keeping it on the desk just so there's no issue with airflow.
When it's idling it's about the same volume as a typical desktop.... Probably a bit quieter. The power management is pretty much the same as an apple laptop. It scales things up and down as needed and you just put it to sleep whenever you like.
Interestingly enough I was able to play Halo (with ALL the eye candy) for hours on it and the CPU's were barely doing anything. (I have the 6600 card). I suppose a newer game would tax it a bit more. - cypherz, on 10/12/2007, -0/+1@SmeRndGy
"wow thats an efficient design. you could probably buy a dell for $300 that is faster than that and just has a normal heat sync."
Stupid comment, Troll. There are some Intel boxen that are faster. They are SMP boxes as well and are in roughly the same price range as the Apple. I could build a faster box for less money, (but not much) and of course it wouldn't run OS X. - xVern, on 10/12/2007, -0/+1+5 respect for apple's hardware.
- abhibeckert, on 10/12/2007, -0/+0Tillemetry, Apple uses subcontractors all over the place. They design their machines, but almost always subcontract the manufacturing to someone else (there are a few exceptions, they recently started manufacturing their own trackpads for example)
- maloney_633, on 10/12/2007, -0/+0That is an excellent example of outstanding engineering. Apple employs some very smart people and some amazing engineers. The real question is why isn't the space shuttle built like that.
- SociopathicHaze, on 10/12/2007, -0/+0mmm..........overpriced trendy goodness. I'm not saying that I wouldn't take one if it was free, but I'd rather wait for the Macintel version. It is very well designed though.
- mvkessel, on 10/12/2007, -0/+0I am amazed!
- NidStyles, on 10/12/2007, -0/+0I want one. That is all.
- mcsurfer, on 10/12/2007, -0/+0Notice the perfectly symetrical layout of the chipset on the sapphire boards- SJ never does anything in a mediocre way.
- gometro33, on 10/12/2007, -0/+0I hate when people try to compare the "speed" of an Mac to the "speed" of a PC. Always an interesting argument considering that there is nothing that either person can say to the other that isn't completely made up. Also, what is "speed?" The number of GHz? If so than Intel took that crown a long time ago. Is it how quickly it opens and runs programs? That has more to do with the software than anything else.
As for this digg...
Very nicely done. Most water cooling setups (mine included) have tubing going all around the case, bending around wires and what not. Very well engineered. - jholdaway, on 10/12/2007, -0/+0No wonder they switched to intel.. Those heat pumps belong on a car!! What power.. My suggestion is to keep the pumps and have intel put 4 cores on a processor. Care for a G6 Octo-Processor anyone?
- rhsjr7, on 10/12/2007, -0/+0I have barely any idea of what I was looking at, but it looked really neat just the same.
- akiyba, on 10/12/2007, -0/+0Somehow I didn't know the Quad G5 was watercooled, but makes sense. +Digg
- inactive, on 10/12/2007, -0/+0wow, this makes the pentium d look like a childs play (in heat output)... I heard that even with all that stuff the G5 macs sounded like jet engine.
still.. that looks cool for what its worth.
(stupid spammers....) - seventoes, on 10/12/2007, -0/+0Wow that's a lot of cooling power... like 95% of the thing is just for cooling!
- BugMeNot2, on 10/12/2007, -0/+0Is that ice I see?
- mntpng, on 10/12/2007, -0/+0Now I know why there was no G5 Powerbooks. Those poor Apple engineers.... I can imagine them being screamed at by Steve but of course they can't change the law of physics.
- nozol03, on 10/12/2007, -0/+0Interesting, but dumb move to take it apart - what was he going to do, some magical Mac upgrades - lol - IBM forever :-P
- dead2sin, on 10/12/2007, -0/+0Even the Cache has a huge heatsink....I think you meant Voltage regulator =) The cache is on Die (Part of the Processor), so that heatsink for the chip is also the heatsink for the cache =)~
- ravuya, on 10/12/2007, -0/+0That is remarkably complicated. I feel sorry for the engineers that have to come up with this thing, but I'm also awed -- it seems really clean at the same time.
- AeonJoey, on 10/12/2007, -0/+0ahhh, reminds me of my days at the Apple FATP in Elk Grove.
miss those days. - CALI-NOOB, on 10/12/2007, -0/+0I digg on the fact that u had the balls to take this apart
- anthonywr, on 10/12/2007, -0/+0It just goes to show that Apple moving to Intel proccessors what not really by choice. Seems they reached the limit of what they can do to cool their processors
- grayapple, on 10/12/2007, -0/+0wonder if he remembered how to put it back together, or did he call Apple care 'Yes, I'm having a slight problem with my PowerMac G5... It came apart... yes, I'll hold'
- disord3r, on 10/12/2007, -0/+0Is that actually liquid cooled? Heat pipes don't always mean there is liquid runnig through them, but I can't confirm it one way or another.
- Scourge, on 10/12/2007, -0/+0Yes its liquid cooled. The manual warns against the liquid coolant leaking.
- dmoffitt, on 10/12/2007, -0/+0having built a number of water-cooled PCs, that's well done imo.
- silent1, on 10/12/2007, -0/+0The processor itself is a chip, which was not disassembled, so you're right that the title is not quite accurate. But now we're just being pedantic. :-)
- orangetiki, on 10/12/2007, -0/+0someone remind me why were going to Intel again?
- electricalen, on 10/12/2007, -0/+0"All I see is that he took apart the computer. When did he take apart the processor (as the title says)?"
I could be wrong, but it looks like those pictures are of the processor assembly and not of the entire computer. So in a sense, he DID take the processor apart. I can't imagine any individual person could extract the IC die and take digital pictures with submicron resolution. - vertigox, on 10/12/2007, -0/+0HA, I have one of those pumps in my DIY h2o system.
http://www.frozencpu.com/ex-pmp-31.html - mark_in_bc, on 10/12/2007, -0/+0Any piece of modern technology that needs that much cooling is just not right.
- Macattack15, on 10/12/2007, -0/+0now can someone explain to me how the xbox 360 only has 1 heatsink and a fan? to me it looks like IBM screwed apple, hopefully Intel won't.
- fudgebrown, on 10/12/2007, -0/+0@macattack: the dual core G5 chip used by Apple is very different than the PPC chip used in the 360. This flavor of chip apple uses the PPC 970, is 64bit and dual-core which created a lot of heat - while the 360 chip is maximized for one thing (graphics) using more simple in-line processes.
- fudgebrown, on 10/12/2007, -1/+1thanks for the short-sighted comment socket.
- Meowmix, on 10/12/2007, -0/+0Haha, poor micromause. ^_^
At the apple stores they have these with the case open. There's a little plastic thingy in there, and it gets REALLY hot. One of the employees got mad at me (this was at the Micro Center apple store) when I stuck my hand in it. ^_^ Fun stuff.
I never realized how complex the cooling system was. Cool!
+digg - Meowmix, on 10/12/2007, -0/+0@slackerdave: Halo doesn't tax the high-end Macs very much. I can play Halo on my 12" 1.5 GHz powerbook with full settings, if only for an hour or so. After that it gets really hot, and the downstairs demands I remove the laptop from my lap.
- test5477, on 10/12/2007, -0/+0thats awesome. takes some balls to take apart something that expensive. that's 3,300 worth of equipment.
very cool, good design apple. - nhm90, on 10/12/2007, -0/+0If the Delphi-produced pumps are anything like the Delphi-produced alternator on my Blazer, he just might be needing that warranty. The Blazer experienced two alternator failures in the first 40k miles. It seems as though Delphi produces some fine products.
- capran, on 10/12/2007, -0/+0Here's to hoping the MacIntels with Pentium M...I mean Yonah....I mean "Core" won't be needing this much crap to cool them. Why is it the G5 does but I've never seen a Pentium 4 Extreme Edition 3.8 (or whatever they're up to now) GHz machine with this kind of kit, except on custom water cooling rigs?
I'm a Mac fan too. But there's no way I'd ever want a machine like that. - Swift2, on 10/12/2007, -1/+1Is not G5, but internal view of LADA laptop, developed by Soviet Union!
- earl, on 10/12/2007, -0/+0So that's a good thing? There's no way I'd have one, unless someone wants to give me one. How much could Apple save if they did not have to cool their CPUs like that. (No I don't think Apple is evil, just misguided somewhat.)
- inactive, on 10/12/2007, -0/+0Cool stuff.
