G5 Macs leaking

Was reading at Macfixit about people with G5s having liquid coolant
leaking after about 20 months. Yikes! Something to look forward to come
March or so.

Anybody seeing this? I'm just wondering how widespread it is. Is it
inevitable or will some of us dodge the bullet?

Bullshit! You can count on one hand the number of people making such
reports. Plenty of hand wringing and FUD going around, however. You're a
hundred times more likely to suffer a logic board or hard drive failure
than a leak. Now when somebody puts up a website called leakingG5.com
and solicits petitions for a class action lawsuit then MAYBE it's time
to look further into it. By the way my June 2004 dual 2.5, liquid cooled
G5 is now almost 30 months old, and has been running 24/7 since day one,
is showing no signs of leaks. However my internal hard drive crapped out
this past September and had to be replaced. Damn the luck. :-)

But to answer your question directly, YES!, someday your Mac will die
just like very other electronic device ever engineered and manufactured
by human beings. You will die someday too.

Thank you. I didn't ask if my Mac would die, I take that for granted. I
asked if anyone might be seeing green gunk leaking all over his/her desk
or floor.

And what's the bullshit? I was wondering how widespread it might be, not
claiming that it _is_ widespread.

Calm down, for pete's sake. It was a simple yes or no question.

No, we noticed that the Mac became flaky, behaved strange etc. and it took us
quite some time to find out that the cooling system was leaking. We noticed
it about nine month after purchase. Apple was unable to fix the problem, that
is, replacing processor, main board etc. didn't help...

By the way: this was not the only G5 with this problem. So there is definitely
a problem at least with some of these G5s.

Har, har! Not as quiet as the Cube, of course. But all the FUD about
racing fans and such was blown out of proportion too just like the
leaking cooling systems. My fans don't race, I can't even hear the
cooling system pumps with the tower sitting on top of my desk about 18
inches from my right ear. According to the utility Hardware Monitor my
cpus are running about 56 C and the memory controller heatsink is 69 C.
Right now the front and rear fans are at about 500rpm and just a soft
purr.

Are Macs indestructible and everlasting? Heck no, they break just like
everything else. What gets my dander up is people trying to take an
isolated case and blow it into a major news story. The MacFixit article
that started it was posted by some guy who has been making the rounds to
every Mac site with his tale of woe. Apple sold hundreds of thousands of
liquid cooled machines. Even if a thousand machines developed a leak
that's still an insignificant number (unless, of course, your system is
one of them). But the "misery loves company" impulse in people makes
them jump to irrational conclusions. "I" have an issue, ergo,
"everybody" has the same issue is how it goes. The guy in question wants
a free fix from Apple even though the machine is out of warranty and he
chose not to purchase Applecare (I did). He's on a mission from God and
he will not be dissuaded from his task.

You can test your PM G5 for potential leaks here. ;-)

Almost all of us. I've worked with 12 liquid cooled G5s (ten in one
location, one each in two more locations.) Ranging in age but most older
than 20 months. Not one leak.
