Cooling system leaks

Ok. You have my attention. It seems like a lot of people are beginning to have this problem. This really concerns me. I have a 2.7 gig dual G5. Does my machine have the modified cooling system, or is it just as susceptible to leaks as the first 2.5 gig machines?

"It seems like a lot of people are beginning to have this problem."
"seems" is the key word here. There are several MILLION liquid cooled G5's out there. There have literally been only a handful of reports and most of them are anecdotal. We do not know the environmental conditions or user status of these reports. You simply cannot jump to the conclusion that a large number of machines are leaking. Do not fall into the mental trap that some do when they come here and see various reports of failures on various pieces of hardware. Even if a dozen people report here that their machine started to leak doesn't mean that a large number of machines are involved. Forums like these concentrate the negative.
You should not be stressing out over whether your machine will start leaking. The overwhelming odds are that it will not. And there's nothing you can do to prevent it if it's going to happen. These systems are sealed and not serviceable by the user. On other troubleshooting sites, like MacFixit or Macintouch, that have been around longer than the Apple forums and have very knowledgeable people this issue is not on the radar screen. I'm not worried in the least bit and I have a 2 year old dual 2.5 Power Mac.

2.7 GHz PowerMac done in by leaking cooling system. THE REST OF THE STORY

This is the story of what happened when my PowerMac went down for the count. I'm posting it because Apple did a such stellar job at resolving a thorny service problem.
I had a Dual 2.7 GHz PowerMac G5 (purchased back in November 2005) that was a major headache all this year. It quit working entirely in March after months of crashes, corrupted drives, and loudly spinning fans. As I was putting the Mac into a box to take it to the local Apple Store for troubleshooting, I noticed a small puddle of what turned out to be coolant. I'd heard the cooling systems on these Macs wasn't very reliable and costly to fix, so I figured it would have to be trashed. Sure enough, when I got to the Apple Store, it was still leaking and the Genius said it would cost upwards of $1000 to fix.
I wasn't happy to hear that, but what could i do? It was out of warranty.
I bought a new 27-inch iMac as a replacement and went back to work. While on the way, I started wondering if I could fix the Mac myself as a hobby project. At work, I posted a question on Apple's Discussions describing what had happened to the Mac and got these replies:
+You should have posted - and looked - on the PowerMac G5 forum, and read up on theG5 Coolant Leak report, and how to deal with it. So check out the Discussion and http://www.xlr8yourmac.com report on the issue (under Systems).+
+http://www.xlr8yourmac.com/systems/G5coolantleaks.html+
and
+Read the xclr8yourmac link and call Apple Customer Service. They replace a lot of leakers with new MacPros if you say there is a fire or electrocution hazard. Read and learn.+
So I checked out the xlr8yourmac site and was shocked. I had no idea how much leaking had occurred, but after seeing photos of the damage to other Macs, the possibility of mine having caught fire while unattended gave me the willies because I'd been leaving my Mac running during the day so the Tools app could run thorough tests.
I called Apple support and told the rep how upset I was over a potential safety problem that was not mentioned on the Support website. He transferred me to Customer Relations where that rep made arrangements for me to get the Mac serviced.
I returned the iMac and gave them the G5 for repair. Two weeks later, I got the Mac back. They had replaced the rear exhaust fans and cable, the power supply, SuperDrive, 2.7 GHz multiprocessor, power supply cover, and the computer enclosure.
In short, they gave me back a resurrected G5 for no charge!
And that was a happy ending that lasted all of five months, during which the fans slowly increased in volume and CPU temps crept higher.
Last month everything went weird. The Mac would go to sleep in the middle of file transfers, sometimes it would hang on restart, and other faults. I called Apple Tech Support and set up a service appointment at the Apple Store.
A week later, I had shelled out $250 for a replacment video card (which seemed strange because video had been about the only thing that hadn't been malfunctioning!) and, fingers crossed, took the Mac home.
It ran worse after the service than before! Fans were screaming, it would crash at the Finder or hang after restart, often wouldn't recognize the Leopard DVD, etc. (But hey, at least video still worked!)
I was getting frustrated at this point, so I called Apple again and worked with a higher echelon tech who told me to reset the PMU switch. It seemed to work, the fans quieted and the machine restarted without hanging. But it seemed dog slow, so I checked Activity and found that one of the CPUs wasn't working.
Another call to Apple where the really helpful tech said it was probably a logic board (the one component that hadn't been replaced already!) and that I should take it in so they could determine if that was the problem. If it was, he would see about tying the repair to the previous service since it was likely that the logic board had been damaged by the coolant leak.
I took it in for repair last Saturday, keeping fingers crossed that this time they'd fix the machine. On Friday, I got a call from them saying that they had "stripped some screws" while performing the service, so the computer couldn't be reassembled. At first I was stunned by the news--now what?!
It got better: As compensation, they replaced my 5-year-old Dual 2.7 GHz PowerMac G5 with a brand new 2.8GHz Quad-Core Intel Mac Pro G5! Gotta hand it to Apple, they did what it took to resolve a maddening problem with one of their products in a way that left me feeling I'd been treated fairly.

Wow! Can't believe they'd give you a new machine on that 5 year old paper weight! Though it was a design flaw. Did you have Apple Care? Just wondering in case mine does it.
I've never had any trouble with my dual 2.5, bought it new in early '05 when the 2.7 came out. I've added memory and larger drives. I've had a problem with a dvd drive I put in it. It would not release the disc on the first eject, if it was a DVD. It's definitely the drive since I now have it in a different machine and it does the same problem. Now I have a Dual Layer burner from a 2.3 dual core.
Other problem I've had with it was a Radeon 9200 card I put in it to get a third display never worked right. I had ATI replace it at least twice and I think it's just a design flaw with the G5. It would stutter on the connected display, slow response time and if iTunes was running the sound would pop.
Removing the card fixed it so the card is back in the box. I'm guessing it would work fine in a G4. But yeah, all problems with 3rd party stuff.
Other than that, no cooling problems or anything else.
I did some speed tests between my 2.3 DC and the 2.5 and the 2.5 is noticeably faster. About a gigaflop. Faster memory on the 2.3 and graphics but slower processor and system bus.
I'm guessing the 4 fastest G5's are the Quad 2.5, then the Dual 2.7, Dual 2.5, then 2.3 DC.

G5 2.7ghz Dual, Leak liquid cooling system:

Hi, my beloved G5 2.7ghz is down, it still powers up but nothing on screen, I need to get this one fixed, Macmedic in Sydney have advised they cannot do anything, has any other user experienced this issue, is there any advice for me? It seems that the liquid cooling system on the processor leaked and damaged the board and power supply. I wonder if it is still safe to operate, and i desperately need to get it repaired as cannot afford another one for my studies! Please advise if anyone had this issue resolved and how.. Thanks!

Hi-
I wonder if it is still safe to operate
No, it is not.
The machine is a fire hazard.
Sorry to say but hundred's of people have experienced what you have.
Repairs can be made, but, typically, logic board, CPUs and PSU need replaced.

For likely much less than the cost of repairs, you can buy a Mac Mini that is pretty much more capable than the G5.

Dead G5 Quad, leaking cooling system - what now?

Have a G5 Quad 2.5GHz with a dodgy cooling system. It's out of warranty by a long way, so I need to fix it myself. I've had a look on the net and the only dismantling guide I can see is for a different cooling system to mine (mine has the twin Delphi pumps at the top), how on earth do I remove this? I've loosened the four hex bolts at the corners, and the two towards the rear centre, but it's still solid as a rock. Help anyone? Failing that, is there some way Apple could do this seeing as it's their crappy cooling system which has caused the damage in the first place?
Cheers

G5 2.5 to 2.0 conversion to remove liquid cooling system

I've had a g5 2.5 with liquid cooling working well for a while now, but now doesn't boot into OSX. So I found the problem being a blockage in the LCS. While taking a part the death cooling unit I accidentally broke one of the cooling blocks and I've already tried everything from high end epoxy to jb weld to fix it with no luck. Looked into replacing it with another comp or parts and it just seems to expensive to replace just for one cooling block. So hear is my question, is it possible to replace the 2.5 g5 with a 2.0? I have the dual 2.5 from 2004 and wondered if the logic board is able to work with the 2.0 from 2004? I like the 2.0 g5 because it has no LCS, just heatsinks or could I use the heatsinks from the 2.0 on a 2.5? I really love my g5 and don't want to scrap it just yet.

Hello,
Sorry to hear this, but did you try Amazon or eBay yet? You should look into it. You might be able to find someone with a busted leaking cooling system, but the block is still good. =) Wish you luck.
Regards.

G5 Quad: Liquid cooling system ok?

Do the liquid-cooling systems in the Quad G5 work ok? Have there been any reports of them leaking?

You see there was this LOUD BANG, followed by a pop
noise. So this guy opens up the side of his Quad and
see's the cover to his processors is a bit loose. He
removes the cover and next thing he's covered in this
green burning acid and it's melting his eyeballs and
everything.
Sorry couldn't resist. :P
Here is how you can test for leaks.

'A problem with the cooling system' error message on Satellite A660

Hi all,
Hope I can get some help here. I've had about 5 HP laptops after all of them had problems and faults. I got sick of them and therefore got a refund and bought a high spec A660-1FH.
The A660 has been a great laptop for two days until yesterday when I started getting a warning message saying 'A problem with the cooling system has been detected. Please turn off the computer immediately, and return it for service'.
The cpu fan works fine as you can here it spinning and the temperature of the i5-460m processor is around 40 degrees for both cores - which seems normal to me. I've noted that it happens only when running on battery and if you switch from eco utility to power saver mode. Its fine when running on the 'balanced' power setting. The fan is louder before when this message appears.
As its under 28 days my retailer swapped it for a brand new one straight away. Got the new one home, and the same message appears again. Has anyone else experienced this. As two laptops have had this, I'm wondering if this is normal for the A660 series laptop or if there is really a hardware issue?!
I have tried to upgrade eco utility and the bios of the laptop but both are the latest versions. Can anyone help or share if they experience a similar issue with their laptop?
Thanks

In front of me I have Satellite A660-13Q (PSAW3E) and I have it about 6 weeks now. It runs almost 10 hours daily and until now I didnt notice such message or anything else that can be suspect for hardware functionality.
I really dont know why this happen on your notebook and dont think there is anything you can do about it.
I would exchange it again. What you can also try is to contact nearest Toshiba service. Make a call, explain the situation and ask if they can help you with this.

A problem with the cooling system has been detected

I bought a new computer not to long ago, I've had it for almost a month now. It runs fine, and I've had no problems until not too long ago. I was playing a game, and I got a random error message: "A problem with the cooling system has been detected. Please turn off the computer immdiately, and return it for service." I don't understand how or why this came up, and I don't have any money to return it for any type of repairs. After I got this message, I left my computer off for about an hour. All seems well so far. Any suggestions?

What laptop do you have?

Clean up cooling system - do it yourself or give it to service

Hi,
I'm a happy owner of X200 for a year. Recently the cooling fan started turning on more often - it's time to clean the cooling system. My question is - will I loose warranty if it do it myself ? (disassembly laptop, put new cooling paste, clean the dust) Maybe I should give it to service? Any people experienced in this topic?
Has anyone disassembled his X200 to do these things? Is it very complicated compared to other laptops?
Thank you for answers in advance,
Kind regards,
Lukasz

if you take out the heatsink/fan then there is a good chance that your warranty maybe voided. If cleaning the vane of the fans and wiping off any dusts don't work, then just send it in, and the depot will change a new fan/heatsink for you.

How to clean the whole cooling system of Qosmio X770-107

Hi Guys,
is there any manual, how to clean the whole cooling system of an X770-107 Gaming Notebook??
I can try to clean the dust on the intake and outtake of the laptop, but whats in the middlepart of the cooling system??
Any Ideas??

As Tonny already wrote all you can do is to use compressed air and try to clean t up.
For professional clean-up the whole notebook must be disassembled. After doing this there is full access to all cooling modules.
Of course this must be done by authorized personal only. Some kind of maintenance manual is not a public document. What you can do is to contact nearest Toshiba service and ask how much such professional clean-up costs.
By the way: this notebook cannot be so old so I dont think it is full of dust.

I have a g5 desktop and I am having an issue with it turning off while im using it. I think it may be something to do with the cooling system

I am wondering what could be causing my computer to shut off while i'm using it. I think it is something to do with the cooling system because it feels hot to the touch and will not turn back on for awhile until it cools down

Is yours an iMac G5:
or a PowerMac G5:
There is a big difference in the cooling systems. If you have the tower, we can get your post moved to the forum where all the G5 tower gurus hang out.

Windows 8 laptop cooling system not working anymore

This morning when I turned on my laptop it said that my cooling system is not working property and I need to turn it off right away . I got my laptop from Best Buy and it's a Satellite C855D-S5104 . How much does it cost to get it replaced? I'm using my iPad to write this by the way. And I wanted my whole laptop like just restart just swipe everything on it and yeah. How much does that cost too?

If its just the regular cooling system then probably its just 10-20 but if its intact w/ the MOBO then roughly its gonna give 50$ or higher i dont know w/ the labors and repair
(Everyone was new at one point)

Cooling system and overclocking?

I've been a PC user for about 22 years now and I'm about to take the plunge and buy a Mac Pro. However I am curious about what type of cooling system the Mac Pro uses for the CPU's? I understand the new 45nm processors run allot cooler so was just curious.
What about over clocking? Can a Mac Pro be over clocked and will it still run cool enough with the current cooling system?
Was reading about someone over clocking the new chips on a PC to just over 5ghz awhile back so I thought maybe I could do that on a Mac.

It is clear for me now that these Lenovo systems are simply not desiged so carefully than the old IBM Thinkpads.
I respectfully disagree with your statement. Take in consideration that your T500 may be around 6 years old and most surely the thermal compound is not so fresh as it was on day one, hence loosing its cooling properties.
I have 3 T500 and 2 W500 with switchable graphics (all second hand). For all of them I have renewed the thermal compound with a good quality one (used Artic Silver 5 in some and Artic Cooling MX-2 in others), in some cases (two if my memory is right) I replaced the heatsinks and fans as well.
All 6 of them have survived several Furmark heavy tests (one of my preferred ones is the 1920x1080 15 min burn-in test) with peaks around 80°C/85°C with a GPU load of 100%. The cooling worked fine in this cases, I see no flaws in design or whatsoever.
Also consider that Thinkpads are/were designed as workstation machines, no gaming rigs. Which kind of games are you using if I may ask?

Cooling system

I have a Toshiba L755D - S5204. Today I turned it on and there was only a black screen. So I restarted it. After that I received a message that said "A problem with the cooling system has been detected" and to turn the computer off. I could hear the fans starting and stopping over and over. Also the screen was darkened. So can anyone tell me what I should do?
