Delphi Radiators spring a leak... in Power Mac G5s!

[FoMoCo Fan]

Looks like Apple should have known better than to contract with Delphi for the liquid cooling system for the Power Mac G5. Apparently only early models are prone to the "leakage", and Apple seems to be fixing them, even when they're out of warranty. But what can you say but "typical" Delphi/GM quality!

MacOSG:Liquid-Cooled Power Mac G5s leaking


By Dave Merten
Reports of liquid-cooled Power Mac G5’s leaking have been been popping up around the Net. Ryan Butterworth at wrote, “So, we have six G5’s all ranging from Dual 1.8’s to a Quad G5. Came in to work today and my computer, a Dual 2.5, wouldn’t turn on. It would click on for about a third of a second and turn back off. Thought the power supply went on it. It was only a year and a half old. Disconnected everything and put it on the floor to try a different plug. I tipped the machine up to show a co-worker when another co-worker spotted liquid coming from the rear of the computer. NO WAY!! It was fine on Friday and untouched all weekend.”

I decided to do some more research and found a guy that had a unit 14 months old that leaked. He did not have AppleCare, but Apple agreed to fix it because it was less than 90-days out of warranty. A few months later, he had another unit leak. This time, the globs of glowing green goo got into his power supply and shorted it out. One of his co-workers described a bright flash and a loud buzzing crackle. Light-colored smoke poured out of the machine, and sizzling coolant dripped onto the aluminum handle. The “cheese grater” back grill had scorch marks. With both incidents, he said Apple was extremely cooperative and provided swift resolution by paying for the parts and labor required to restore the G5s back to working condition. He also noted that he did not lose any data on either machine.

So what’s going on here? It seems that the early 2.5 GHz liquid-cooled G5s shipped with Delphi radiators that were problematic. That may have been the reason Apple delayed shipment for three months after the liquid-cooled G5s were introduced. Apparently Apple may have been having problems with them from the beginning. So, what should you do if you own one? I would recommend pulling the side metal panel off periodically and checking the rear bottom floor of the computer for leaks. If you find a leak, get it serviced ASAP. Don’t keep using it. Also, Apple recommends cleaning the fluid up with rubber gloves on. The fluid can irritate your skin.

As long as Apple will fix them in or out of warranty as this only effects the early built models, this is not that bad of a situation. In matter of fact, I knew about this 2 years ago when the Dual 2.5 came out! :p

Of course! We might as well name the new Malibu the "Camry" and rename GMI to ToyotaNation. LOL

Liquid cooled radiator on a computer? Is'nt that kind of like having a gas powered shaving razor?

Liquid cooling has been in the modder/overclocker's bag of tricks for several years now, actually. I didn't know Apple was using it on a mainstream product, however.

Sorta. Liquid cooling is much more effiecent and can be quiter. The types of Macs they are talking about are hardcore workhorses.

Well, I'm going to buy a Mac Mini anyway. No need to cool that little sucka!

Who lets this guy post news? This is an automobile enthusiasts website, not a computer geek website. Macintosh sucks, it's their own fault. Oh, and by the way, Ford uses Delphi parts.

That would be a blatent rip-off. I suggest we re-name the Malibu "Camree" and change GMI into TheToyotaNation

Yeah. They put on the Dual 2.5's 2 years ago when they were released. And still equipped on todays Quad G5. While Apple claims it was put on to make the computer quieter( which it does), many speculated the machine needed the liquid cooling because the 2.5 Ghz G5 chip was actually an overclocked 2.2-2.3 Ghz chip, but there is no proof so far to prove that theory.

Macintosh sucks, it's their own fault.

You go enjoy your viruses now.

Golf Club Maker Ping has a club called the "G5 hybrid" out now, with a television commercial for it also.

If you are only casually listening to the commercial, you would think its about a new GM car. I swear they must say "The new G5 hybrid" about 7 or 8 times in the 30 second commercial.

Yes cause Ford's "Quality Is Job One" mantra has really worked for them! "Have you driven a Ford to The Shop Lately"

That's just funny.

Macintosh sucks? How many viruses and spyware have you gotten with Winblows?
There's a $100 premium everytime you buy a PC because you have to buy Firewall and Antivirus and Antispyware software.
My Mac has none of the above.
