G5 Dual 2.5 Cooling Issues?

My computer is typically on for long periods of time when I am working and so this problem is rarely an issue that causes problems, but it seems problematic for a machine of this design (its not like I'm on a Windows machine). Any time that I have been working on the machine for a little while, no matter how little work the computer does, it will not start back up immediately. The power button lights up but the computer does not start up. The only remedy that I have found is to wait, after a while (longer/harder the computer was running the longer I have to wait) it starts up and runs normally. I assume that it is a cooling issue because of the relation to the computers work load and how long it takes to work again. This used to occur some of the time, now it seems to be a guarentee that it will occur any time the computer is running for a while, hour or so. Anyone have any experience with issues like these or understanding of what is going on I would appreciate the input.
Thanks.

I downloaded Temperature Monitor
and my first processor is getting up over 200 degrees
F. I
That's getting up there near thermal shutdown. It sounds like your LCS may need to be replaced.

Dual 2.5 cooling issue: Won't boot.

I have a dual 2.5 G5 that I've had since it was new in in july 2004. It's never given me any problems.
Recently it started "gurgling" (it's the best way to describe it). I was worried about the dreaded leaking issue so I tore it apart looking for leaks.
Good news: No leaks. Bad news, it won't boot now.
In the process of assessing the situation I checked the coolant level. To my surprise the system was pressurized quite a bit, even though it was stone cold. I don't understand this. I also get the red LED's on the mother board glowing indicating overheat, the cooling fans run at high velocity, and the computer won't boot.
I am in the process of rebuilding the water pump as a preventative measure, resealing the two O-rings and the diaphragm. Everything seems in working order.
I hope it will boot once I reassemble it, but I'm in a situation where I MUST have it up and running by monday.
Any suggestions?

Hi tarmaque-
It may not be so much about pressure as air in the system. You said yourself that it was pressurized when you disassembled it. That is a huge clue! That fact alone would certainly make me think that there should be pressure.
I think the higher boiling point under pressure is a factor. There isn't much fluid and it must dissipate a lot of heat.
Water cooled engines absolutely are "pressurized"-ever take a radiator cap off of a hot engine? A cooling system must be able to handle pressure as (duh Daddy) liquids expand when hot.

MSI gtx 570 twin frozr III - Dual Screen Windowed mode issues

Ok, so... I was running a solo monitor 1440x900 resolution, i recently purchased a brand new asus 24 inch 1900x1080 monitor. Basically what is happening is when i play WoW or Battlefield 3 in windowed mode on the 1080p monitor the colors are not perfect. When i go full-screen on the new monitor no issues, but that is not what i want to have to live with. When i say the colors are not perfect what i mean is, for example when i look @ the sky instead of being a smooth transition or blend from one shade of the sky to the next it is bars or stripes of each shade as if i am looking at the sky in 8 bit color instead of 32 bit color. Another thing to note is that when i login to windows 7 the blue screen where i input the password has the same effect. The 1440x900 monitor is running everything just fine. the only issue is with the 1080p monitor.
I am using DVI cabling for both, and have swapped them around to see if that was the issue, and sadly it is not. I am running the updated gpu driver, which i uninstalled and re-downloaded and installed again tonight.
When i use the HDMI cable, that fixes the issue but i need the HDMI for my 42 inch tv.
Also in windows, just to cover my bases with this post, i have the native resolutions properly configured, as well as in the game for the given monitor it is being played on.
Anyone know of a fix for this?
i7 2600k
asus PBZ68-v Pro/Gen3
Msi gtx 570
Samsung syncmaster 953bw (1440x900)
Asus VS248 (1900x1080)
I am more than happy to re-explain anything that may not be as descriptive or clear to you just let me know!
EDIT!
When i run the 24 inch 1080p new monitor as my only monitor on the system, everything runs perfectly...
Edit #2
Ok so i have pin pointed a possible cause
This msi gtx 570 struggles with operating multiple displays with different resolutions, while dual screening with my 1080p television and the 1080p display, everything runs as expected. Having to also render a 1440x900 display is probably the reason i am having the graphic issues. Is there any type of utility, setting, or other fix to this type issue? also this gpu is certainly less than 2 weeks since i purchased i could get a different card to remedy this... any suggestion? if you suggest a different card can you say so with certainty that it will work properly under the condition in which 2 resolutions will be required?

Ok, the problem is fixed and Svet i skipped a step or two. I installed the new driver with the clean install to save time for an initial attempt. What is interesting is that with the Geforce driver, only one 1920x1080 resolution was available
The msi driver gave me 2 options, 1920x1080 and 1920x1080 (native). The latter resolution fixed the issue for whatever reason.
The solution to this problem is so easy, when i purchased battlefield 3 it prompted me to download the geforce.com driver and i did not think anything of it at the time, lesson learned.

X79A GD65 (8D) Sub Zero cooling issue getting 91c ??

Hi All
Been on phase for years just a fyi
Issue is on this board using phase shows 91c and locks the settings to stock speeds?? on air or water no issues I can get 5.0 seems as soon as I go on my SS which goes -50c I cant OC as the cpu temps shoot right to 91 calling for it to go stock!!
Any help would be
Thanks
T&B
PS I have the jumpers which I dont need as it boots fine this is just as soon as I go to OC in any form.

I would get the cold bug but this accures even on water cooling for some, I ran across another guy with same issue except he is on just water.
I can run easy on Air up to 5.0+ with good temps as well! Now they built these for LN2 as there are 2 jumpers on the board for cold booting but I dont have a boothing issue get into windows easy it is just when I go to OC anything above STOCK then the temps reverse to 91c from 0c very strange.
Hope MSI has something I can try or no extreme cooling..................
Also worked with the Gig UD7 big time issues with just booting but no chiller issues still had to rma the board for new one as it would go into these ramdom loops.
Worked with the Asrock extreme 9 now this was a joke theres a saftey in the bio's hidden that wont allow extreme cooling, I'm in wait mode for them as well.
Come on MSI send me something to make this work I have 2 threads up to show results on different cooling.

Wifi, power and cooling issues with my MacBook Pro.

I've had my MacBook Pro for about 2 years and I've been really pleased with its performance from work I've thrown at it. I initially got this MacBook Pro refurbished from the Mac store and it has a Apple Care protection plan. Although this past year I've noticed several issues that are probably hardware related. First, my MacBook's WiFi does not receive WiFi signals from the great distances it used to anymore. The times I can pick up WiFi are within like 5 yards from my wireless router. Second, I'm having an issue with the power. This past week, it seems my Macbook Pro does not run off the battery anymore. It only powers on when connected into the power supply. If I unplug the power supply, my Macbook turns off. It does not revert to the battery which is strange. Third, cooling seems to be a problem. The Macbook Pro is getting very hot. It burns my lap when it is holding there. The cooling problem has lasted since I got my Macbook back in January of 2007. I thought it was normal since I would load the CPU with some graphics intensive games. Now the Macbook Pro gets hot to doing some less CPU intensive tasks like surfing the web or word processing. I have noticed, a decrease in performance, longer boot times, loading of web browsers, and word processing applications. Would this be the best time to consider taking my Macbook Pro and for repair with apple care? I'd like to trouble shoot these issues to know exactly why these problems are happening. I have a feeling it could be due to the Macbook Pro getting hot. As for cooling I go by the manual and place it on a table or hard surface, or my lap. I pretty much want to know what is wrog and how to prevent issues like this in the future.
Thanks.

Welcome to Apple Discussions!
It sounds like you have several issues:
I don't know why your MBP can only receive wireless signals from 5 feet away. Unless possibly the antenna has worked loose. But I'm just guessing.
Regarding the power, is your battery still good? Have you tried resetting the SMC?
http://support.apple.com/kb/HT1411?viewlocale=en_US
Regarding the heat issue, have you tried running the extended version of the Apple Hardware Test? If you check your fans with iStatPro, are both running at an appropriate speed for the heat?
Also, have you checked in Activity Monitor for any out of control processes which might be running in the background and hogging the CPU?
A good place to start would be with the AHT. Since you have Applecare, you should also have a Tech Tool Deluxe disc, and you can run that too. Should anything turn up in the form of an error code, that would indicate a hardware problem. Write down the code and call Apple to arrange for repair.
If you have access to an Apple Store, you could also just take your Mac in for evaluation.
Good luck!

Fan cooling issue on Satellite L850-11D

Hello,
There's a big problem with my CPU Fan speed. It keeps running at 20-30% (about 950 RPM) while CPU/GPU temperatures are high. I cleaned fan with air, replaced thermal grease. I changed all setting to High performance and Active CPU cooling system.
Sometimes fan speed increases to about 60% for few seconds, but then immediately goes down, back to 20%. I bought this laptop 6 months ago and it was working very well, with high fan speed (90%+ during games).
Now when i play some games it just turns off after few minutes.
If someone knows how can i fix it, please help.
(I can make SS of temperatures/fan speed sensor if required)
(sorry for my english)

I agree with as***the unit is 6 month old so from my point of view the warranty was still valid
In such case if the cooling module would be faulty the notebook would be fixed free of charge.
But you have disassembled the unit at your own hand big mistake buddy because now the warranty isnt valid anymore :(
I have no other recommendations for you.
As as*** wrote; try BIOS update since the fan table is stored in the BIOS.
But I assume its hardware related issue since this cooling module worked properly in the past.

Qsmio x505 Cooling issue

I received my latop back from repair today and it's giving me problems. The fans were replaced because they were making a buzzing noise. Ever since I got it back, a message saying: "A problem with the cooling system has been detected. Please turn off the computer immediately, and return it for service." pops up randomly. The computer isn't overheating. I checked with a program I installed after the issue started to make sure they weren't. The only thing that happens is the fans go turbo and blast out a lot of air seconds after the message pops up. So far nothing really bad has happened, but I'm afraid it's a matter of time. I don't want to send it in for repair again. I just sent it in twice over the past 30 days for two different reasons. Is there a solution for this?

Please include your full model number when posting problems on the forums. It can be found on the bottom of your laptop.
While the laptop might not be overheating at the current time, it is possible that something wasn't done completely correctly when it was repaired last time that could cause this. It'd be hard to tell whether this message is a false positive or indicative of a real problem without servicing!

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.
Start your research here:

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

IMac Cooling Issue

Before i installed Snow Leopard i had a program called SMC Fan Control that allowed me to change the speed at which my fans operated and it worked great it cooled my computer down by almost 20F most of the time with the fans operated at their peek but after installing Snow Leopard the program no longer works due to support issues now i use a program that is a preference pane called iMac Fan Control and it works like it should but when i put the fans at their peek they don't sound like they used to and barley cool my mac down by 2F how can i improve this because it seams like this is the macs issue not the program.
I am also wondering what people think a good temperature for my mid 2007 iMac would be.

I have SMC Fan Control and have no problem using it with Snow Leopard. In fact I downloaded it AFTER installing SL. As I recall, when I went to the web site it said something to the effect "now compatible with SL". My version of SMC FC is 2.2.2. Perhaps you have an earlier version?
As to fan speeds, the noise starts bugging me if I set any of the 3 fans higher than about 1800 rpm. I can't imagine setting them at 4000. In addition to the noise I would think that's a recipe for reducing your fan life considerably.

R6970 lightning cooler issues

I acquired a pair of R6970 Lightnings recently. I noticed the fan on one of the cards ran extremely loud, so I started to troubleshoot the issue.
The problem would dissapear when I turned my case horizontally, which made me believe the issue is with the cooler.
When I ran the kombustor stress test on the cards individually, one of the cards would last about 5 seconds before it failed the test and froze up the system, with garbled video output. As soon as I would lay the pc case down on the side, the kombustor test runs indefinitelly without any issues.
So it seems to me the heatsink retention screws aren't up to par, causing the heatsink to not make full contact with the gpu, when the case is upright. I checked the 4 screws with springs on them to make sure they're tight.
My question is, has there been any other instances of this happening to anyone, and how did you go about fixing it?

@cuttz
Only one of the video cards exhibits the issue. I ran them in crossfire, and individually, pci slot one and slot two, and regardless of the combination, one of the video cards locks up the system after 45 seconds if the pc case is vertical. If horizontal, it takes about 5 minutes. I was actually able to reproduce the issue even when the case was horizontal by very lightly pulling on the edge of the heatsink shroud away from the pcb.
@henry
I must have reseated the cards a million times, as well as the connectors. Nothing helped. I've tried every combination.
After about 10-12 hours of troubleshooting, I now believe there is a loose connection somewhere on the pcb or inside it. Maybe a loose component that was the result of a bad soldering job at the factory. I visually inspected everything thoroughly, just to make sure i didnt miss something obvious, and I didn't find anything out of the ordinary.
So in the end, I've decided to RMA the problematic card so as to stop myself from pulling my hair out. Hopefully the MSI techs will have better luck in diagnosing the issue.

G5 Powermac Dual Core Power Supply Issue

My G5 Dual Core 2.3 GHz was working fine till this morning when at about 6:00 AM the power supply started making a bunch of noise. Luckily I was at home not at work so I pulled the plug...waited a while, powered on again, saw the apple logo and decided to turn it off till I get it fixed.
This is the third G5 I have with power supply issues. The first one was a dual processor that hums when doing a lot of networking or when attaching USB flash drives...so apparently there was a extension program on that one. I sold that and switched to the dual core machine, then both of the dual cores had power supply issues. One got replaced under Apple Care. The 3rd one just had the issue happen.
Anybody having bad luck with these? My old G4 DP 1.42 has been running almost flawlessly since it came out (only replaced the main fan for a more powerful and quieter unit).
Have the power supplies for the Dual Core G5 machines been redesigned or should I expect my new one to fail again?

Hi Jack,
I'm sorry. You did note that with your first G5 you knew of the extension program. Too early in the day for me I guess. Personally I haven't sensed from the G5 discussions that Power Supplies have been a major continuing issue, but there certainly have been a lot reported. Usually it's Logic Boards that keep getting fried for one reason or another. Fortunately it doesn't seem to be the most expensive thing to replace, especially if you buy a used one. Maybe someone will chime in who is more observant then I am this morning.
For what it's worth I still have the first Mac I ever bought which is a PM8500. It still runs fine whenever I pull it out from it's dusty storage. By contrast this is my third G5.
Edit: Up early and fasting for a test... I just caught your reference to 3 years. That time frame I have seen a lot here, usually 3 years plus a few months, just out of Applecare. Apparently for G5s thats like 90 in Mac years.

Dual Layer DVD Burner Issues

Hello every one. I recently purchased a Sony DRX-810UL/T External DVD burner and am having a few issues with it. I have it connected through firewire to my mac mini runing the latest version of panther. It works well with Toast lite which shipped in the box, however if toast isn't launched, and I insert a dvd into the drive, I get the usual prompt asking me if I want to ignore, eject, or burn the disc. Regardless of which option I choose the disc ejects and i get an error message (0x80020025) telling me the drive is not supported. I posted a message on the maccast forums and was told that it was an issue with panther that it had trouble with dual layer burners. I also read one article that said relaunch the finder would fix this problem however that did not work. I am wondering if anyone else has experiences the same or similiar issues using a dual layer burner in panther. Just to clarify i am not trying it with a dual layer disc, it is a single layer dvd.
Any help that can be offered would be greatly appreciated.
-Matt

Hi Matthew
I have a Dual Layer burner(internal) on my Mac running Panther 10.3.9 plus another burner and when I connected them,I had the same problem.Then,I installed an app called"Patchburn"(it's freeware)and since then,no problems,it recognizes both burners

9.2.2 on Dual 1.25 Booting Issue

I've had this issue for a while and now I just need to know the answer. I have a Dual 1.25 MDD PowerMac G4 FW 400 and I want to load 9.2.2 on one partition. It wont boot from the 9.2.2 CD. Some mention video drivers and some mention OS Rom files. Funny thing is I had this same harddrive in an older G4 partitioned with 10.3 and 9.2.2 and just threw it in the Dual 1.25 and both OS partitions worked. Anyone have insight on this issue? Thanks

Hi, RunLogan -
There is no stand-alone OS 9 Install CD suitable for use on your machine - most such, if not all, since thay are model-specific to another model will not be able to boot your model.
All G4 MDD models came with a combination set of install disks - although the disks boot to OSX, you can install/re-install Classic (OS 9) from that disk set. One or more of these articles should help -
Article #106294 - Mac OS X: How to reinstall Mac OS 9
Article #60847 - How to Perform a Multiple Disc Restoration
Article #107383 - Mac OS X 10.2, 10.3: How to perform Mac OS 9 clean installation with Restore CDs
Article #42929 - Using Restore Discs with Mac OS X 10.2 or later
The installer will insist upon placing Classic (OS 9) on the same volume where OSX resides. So be it - do that.
Once the installation is done, boot to the freshly installed OS 9. Then copy the OS 9 System Folder to the volume you want it on - just drag it to that volume and let go, let Finder copy it there. Do the same with the new Applications (Mac OS 9) and Documents folders created by the installation of OS 9.
Once that is done, test boot to that copied OS 9 - use Startup Disk control panel to select it as the boot volume and restart. It should be usable immediately. If so, you can then trash the original installation of OS 9 on the OSX volume.
Note: you may need to fix a few aliases after copying to the OS 9 volume - the alias for Sherlock in the Apple menu (it lives in the Apple Menu Items folder in System Folder), and perhaps a few in the Application Support folder in System Folder.

MSI Big Bang XPower II - Corsair H60 Water cooling issue

So I am using a Corsair H60 water cooling on my MSI Big Bang XPower II mainboard. I have followed the correct instructions on installation but every time I turn the computer on once it its 31 it shuts down. Everything seems to be working correctly except the cooling. There are no instructions that really relate well to installation for this water cooling to this mother board so I have tried placing the pump power and the fan power on various different inputs. I have the pump just on a sys power fan and the 120mm fan blowing through the coils on the back of the machine connected to the CPU 1 head fan (as instructed in their videos). I am not 100% sure the pump is working but I know that the fan is working and the hardware overview shows it recognizes the fan.
anyone have some ideas to try to see if I can get this to work? I am also wondering if it is a faulty pump or something but it seems to be working.

Quote from: seth.eckert
I have the pump just on a sys power fan
The pump is not working. The 3-pin connector for a fan header is just for reading out pump speed. You need to power it with the molex connector.
