Power mac cpu temps
what is the normal operating temperature for a power mac g5 quad modle
In my case, the inside temperatures vary a little according to the room temperature, which is about 68ºF in the winter to about 78ºF in the summer.
Here are some Hardware Monitor screen shots at various times:
Generally speaking, the consensus seems to be that if you don't see core temperatures rising above 158ºF / 70ºC, there's no cause for concern.
2.5 GHz Power Mac (PPC) G5-Quad; 16GB RAM; mutant, flashed 550MHz nVidia GeForce 7800GTX 1,700MHz 512MB VRAM; ATTO ExpressPCI UL5D LP SCSI card; Mac OS X Tiger 10.4.11 and Leopard 10.5.8 boot drives; intrusive Spotblight, Dashboard and Time Machine permanently disabled; dual 22" CRT monitors; USB wireless 'n' available but connected to the Internet via wired Ethernet; FW flatbed scanner; 2 SCSI scanners (one tabloid-size transparency scanner and a film scanner); various internal & external HDs; FW Epson 2200 and Ethernet Samsung ML-2850ND printers; 2 X Back-UPS RS 1500 XS units.

Normal CPU Temps for Power Mac G5?
Hello All,
I just wanted to know, since Im very curious about my temperatures since Im really trying to avoid the Logic Board failure due to Lead-less solder. Ive installed heat sinks on my DDR-SDRAM cards (x4 1GB Apple OEM chips (they bear the Apple Logo and have " Memory Module" on the stickers) I got four of these heat sinks: http://www.newegg.com/Product/Product.aspx?Item=N82E16835110105 and they work extremely well, however I dont possess the required tools to remove the processors to apply Arctic Silver 5 Thermal Paste, and these processors have not been budged one bit since purchase date. This is a Second Generation June 2004 Power Mac G5 DP 1.8GHz. The Processors temperatures are typically around 150ºF-160ºF Im using iStat Menus. Fans arent even noticeable. Nothing makes noises at all, I was just wondering if this is normal activity and if I need to take the heat sinks off and apply AS5 paste. If temps go above 160ºF, I pull the side panel off the Power Mac as well as the air deflector and I remove the "G5 plate" from over the processors and let it vent (still running normally, Im not sleeping it or shutting down) and processor temps come down to 130-135ºF. Should I worry about logic board failure if I leave them at 160ºF (both CPU A and CPU B are always the same temp (usually within 2ºF of each other) This is my only Mac other than an over clocked eMac (900MHz from 700MHz) and a DP 1.0GHz Xserve G4. I want to keep this G5 in working order as long as possible. Thanks so much. Also, by the way I have been dusting this Power Mac out every week since day one using compressed air. There has never been anything more than the slightest amount of dust in this machine, sometimes no dust at all. This machine is well looked after. Thanks in advance.
Regards.

Heck, KMart, WallMart, Ace Hardware, etc., will have similar.
I will try the Arctic cooling MX-3. Now, where can I get my hands on such amazing paste?

It's been a while since I took a look at the my temps and what not using Hardware Monitor but the other day I reached behind my Mac Pro... it seemed to me that it was awfully warm... so it peeked my curiosity...
Today I checked and my CPU temps are all around 135F... as I said, it's been a while since I looked but I seem to remember them being sub-100F at idle...
Am I not remembering correctly?
Thoughts?
Thanks!
-JustinSee if installing SmcFanControl 2.2+ to create profiles and change default fan speed works, changes the fans.
Rather than wait for the system to heat up, switch to a higher rpm profile for that purpose, say 900-1000 rpm is still just barely audible but moves much more air and cooling. 1200-1500 for high.
Once the fans kick in, or cpus are under a work load, it can end up being cooler than it was.
The new 2009s with HT can be forced to use more power, create more heat. For 2006, the big issue is/was the ATI X1900 and clogging with dust and overheating, which needs to be pulled and cleaned every 3 months. -
What are the normal operating temps for a G5 Quad Core Power Mac Tower?
I asked this within another thread but I am afraid it will get buried and think it deserves its own item.
I just downloaded Temperature Monitor and have been looking at the data. I have no idea how to interpret the figures and there are no listings of specified upper and lower limits even though there is an area where those numbers should go.
The numbers are constantly in flux, going up and down a degree or two but here is a recent example from a screenshot taken while I was running WORD (but not working on any document), Terminal, Apple Mail, Firefox (two windows open), Temperature Monitor, Preview, Dashboard and Finder:
Air Tunnel 99.5 degrees F
Air Tunnel Heatsink 92.8 degrees F
CPU A Core 1 Diode 107.5 degrees F
CPU A Core 2 Diode 107.8 degrees F
CPU B Core 1 Diode 108.0 degrees F
CPU B Core 2 Diode 111.5 degrees F
Drive Bay 87.8 degrees F
Graphics processor chip 131.0 degrees F
Main Logic Board Air Inlet --- (this is always missing)
Main Logic Board Backside 108.7 degrees F
Memory Controller Diode 133.9 degrees F
SMART Disk WDC WD2500JS-41M.... 104.0 degrees F.
The icon for the program, in the dock, gives me an ever changing number that is perhaps an overall reading - an average. Right now the number is 106.4 degrees F (taken some minutes after the screenshot providing the above data). Always in flux.
Do any of these temps look alarming? And HOW and WHERE do I find out what the temperatures SHOULD be?
PS I have APPLE RAM.If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press Apple+1) and look for the limits in the third and fourth column of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.

Power mac g5 quad cpu runing hot
ok my power mac g5 quad the top cpu core 1 and 2 are runing really hot and ween itryed to turn it on this moring the fans all went to max and shut off i then tryed to trun it on again and it just went 'click' and i unpluged ever thing left it alon and came back about a hour later and tuned it on and ween it got to the main desk top the fans were on max and the top cpu cores were about 155f 165f and the outher cpu was runing fine what could this be a computer guy told me this could be that i need new thermal paste pleassss help
The thermal paste degrades after 3-5 years of use.
Whether anyone wants to or not, the thermal paste in ALL G5 machines needs replaced.
LCS systems, even without leaks, can have reduced performance due to sludge buildup or loss of volume due to evaporation and escape of those liquid vapors.
Serious consideration should be made towards rebuilding the LCS for longevity of the computer. -
Trying desperately to upgrade my Power Mac G5 Dual Processor to Mac OS X.4 - what kind of upgrade is needed? How may I proceed?
Hello Jens,
Might be easier to get Leo/10.5.x
Tiger Requirements...
To use Mac OS X 10.4 Tiger, your Macintosh needs:
* A PowerPC G3, G4, or G5 processor
* Built-in FireWire
* At least 256 MB of RAM (I recommend 1GB minimum)
* DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
* At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools (I recommend 20GB minimum)

Power Mac G5 Dual 2.5 freezes up, Power Mac G5 Dual 2.5 freezes up
Hello
I inherited a Dual 2.5 PPC Power Mac G5 from my sister. She was having problems with it suddenly freezing up. She replaced the hard drive but that didn't fix it, and sicne she had a newer Macbook Pro she gave up on it. When I got it I replaced the video card on it with an ATI Radeon, and it seemed to run fine for a while, and then the problem returned. It seemed to have returned after I did all the Apple software upgrades on it (It's running Leopard), but that might be a coincidence. I noticed under Diagnostics on the power up test that some RAM had failed. I also noticed that it was running on 1 gb of RAM even though 2 gb were installed. I removed the faulty Ram (4 256 mb dimms) and hoped that that was the problem. Unfortunately it wasn't. I also installed a temperture reading program. It showed that CPU A is running around 80 C at times and is usually about 10C hotter than CPU B. I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time and date, and took a look at the battery, and sure enough it was starting to leak (but hadn't leaked on to any components). I've ordered a new bttery for it.
I ran a check with Disk Utility and found the HD was ok, but permissions were a bit messed up. Disk Utility wasn't able to fix some of the permissions, but i don't think this is the underlying problem.
I've also opened it and gave everything a thourough vacuuming and cleaning and reseated any removable parts. I took the cover off the liquid cooling unit and vacuumed out the dust. There didn;t seem to be any coolant leaks I could see.
Any suggestions on where I should go from here? I unfortuantely don't have any of the disks for it, so I can't run the AHT until I find one for it (the one for my Macbook Pro wouldn't work).
Sometimes it just freezes. Other times it freezes and the computer fans go on high. It will finally get to a point where it shows the grey multi-language restart screen (where it says to hold down the button to shut it off and the restart).
It was frustrating because on my workbench it was running fine after I switched the video card, and it didn't freeze at all. When I moved it to our computer desk though, the problems returned. Tonight it was to the point where it didn't last 5 minutes.
My thoughts are:
1. Maybe All the RAM is bad
2. Maybe the dead battery is messing it up?
3. When it is heating up with use, something is expanding and not connecting any longer.
What are your thoughts?Hi Curtis,
I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time
Nope, not normal, way too hot, above 70°C... If you have any temps in the 70°C/160°F range, that's likely it.
Have you blown the dust out of everything with high pressure air?\
1. Maybe All the RAM is bad
The Memory test can really only be trusted if it finds a problem, not if it doesn't find a problem.

Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help
Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
This is a NOT an Intel machine. I am running Mac OS X v10.5.8
Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.

When did the fan problem start?
After I replaced the mother board on the computer.
Why did I replace the mother board?
Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500
CPU A Die Temperature: 75.7℉
CPU B Die Temperature: 81.5℉

Processor Card A Ambient: 77.5℉
Processor Card B Ambient: 77.0℉
5) zapped the PRAM
6) followed the SMU reset instructions for
Power Mac G5 (Late 2004)
To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
• Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
• Remove the power cord from the computer.
• Wait two minutes.
• Plug in the power cord.
• Turn on the computer.
7) followed the SMU reset instructions:
Resetting the Cuda/PMU
How to reset the PMU:
• If the computer is on, turn it off.
• Disconnect ALL cables from the computer, including peripherals and power.
• If possible, move the computer to a place where you are not standing on carpet.
• Open the case and ground yourself by touching part of the metal frame inside the computer.
• Find the Cuda or PMU button
• Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
• Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
• If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
8) ran disk utilities, repaired permissions
9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
10) restarted the machine, ..
11) found a Fan Control System Update - but it did not install when I tryed to install it -
12) booted from OSX install disk and ran that disk utility
13) used OnyX to fix disk permissions, clear caches and temp items
Nope - still have the same high speed fan problem. ... PLEASE HELP!!
I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

Power Mac G5 Dual Core freezing
Hi,
Everything works fine with my G5 with 4GB RAM, except one thing:
Sometimes when I work for a long time, my mouse justs freeze,
The red light near the RAM slots appears and the fans start being noisy ! (LED 7—Checkstop: red—contact Apple or an Apple Authorized Service Provider)
I reboot and all just works fine until the next freeze
I ran Hardware test and apple diagnotics many times but all the tests including the ram test passed successfully.
It happens like 1 or 2 time by day. I couldn't identify the cause or the frequency of the problem (maybe Eyetv usb box, or a spécific app that causes the computer freezing ??? !)
Thanks for the help !
Power Mac G5 Dual Core 2,3 Ghz Mac OS X (10.4.8)Curiously - we have two new Dual 2.3 G5s and they exhibit this same behavior. Suddenly freezing - and not necessarily while we have a lot of apps running. iTunes is always going in the background though. I'll start monitoring the temps on these machines and we'll see what happens. Does anyone know of a menubar app that might display CPU temp on the fly? Could be useful if we see a spike in temperature and then a crash.
One notable thing though, when it does crash, it crashes hard. Everything freezes, the audio (since iTunes is usually running) begins to skip on the last section of the track it was playing, sort of like a skipping record - only much faster. It also appears to have happened to one of the machines last night while it was asleep. I came in the morning the the fans were going crazy - and yes, the little red LED was on. What does that mean?

Temperature Concerns on Power Mac G5 Dual 2.5
After having my PowerMac G5 Dual 2.0 power supply burn up and take the rest of the computer with it I am concerned about my PowerMac G5 Dual 2.5. I am hoping someone out there can let me know if my values are normal or if I have reason to be concerned.
Here are the stats on my Mac:
Model Name: Power Mac G5
Model Identifier: PowerMac7,3
Processor Name: PowerPC G5 (3.0)
Processor Speed: 2.5 GHz
Number Of CPUs: 2
I am using Temperature Monitor to determine the temp of my computer.
Here are the results: Time Interval: 7 Days showing Minimum and Maximum Temps
CPU A Temp - 55.1C/131.3F Min - 93.1C/199.5F Max
CPU B Temp - 49.6C/121.4F Min - 80.4C/176.8F Max
Main Logic Board Backside - 42.0C/107.6F Min - 50.8C/123.3F Max
Memory Controller Heatsink - 62.6C/144.7F - 72.4C/162.3F Max
Are these typical ranges for this machine? Looking at the history window the CPU spike occurred about 4 times over a 7 day period. For the most part it stayed under 70C.
I have searched the internet and I can't seem to find out what the normal operating temperatures should be for this machine.
Thank you in advance.I just reassembled my G5 (2004 2.5 GHz) cooling system last night and now appears to be working properly. Before the repair the fans were running full speed nearly 100% of the time - hardware tests indicated a temperature alarm condition for CPU A that prevented booting when hot. CPU A was typically running 10-15 ºC higher than CPU B. Other than the fan noise and booting problem the system was stable, never crashed. After disassembling the CPU's and heat sinks I believe the problem was the dried thermal grease between the CPU's and heat sink and/or the gunked-up copper fins of the heat sink. In addition, the o-rings had taken a set and the coolant had begun to seep out - no liquid, but visible residue around each of the heat sinks. I feel most, if not all, G5 water cooled systems (at least the 2.5 GHz models) will begin to exhibit these symptoms of failure.
What surprised me most about the repair was how easy and inexpensive is was. After reassembly the CPU temperatures were about 1.5 ºC apart, averaging 50 ºC under a light load. Note, the CPU's will never operate at the same temperature since the heats sinks are plumbed in series. -
CPU Temp spike to 120c for no apparent reason. Help!
Hi,
I've got a 2.5 dual G5 4gb ram and yesterday I noticed the fans were running constantly for about 5 min. I had Photoshop and Illustrator running so I didn't think much of it (cpus were running at about 60% in activity monitor). Next thing I know I get a black screen that went away after I moved my mouse (It did this twice). I quickly shut down the programs and all was well. I did a bit of research and figured out that this is due to the cpu's overheating and it's putting the system into sleep mode. It's never done this before, and I work on these programs daily.
Well, I decided to download a temperature monitor today so I could keep an eye on what the temps are. I was listening to a podcast a that was approx. 30 min long (no other software running but Firefox, activity monitor, and the ). CPU temps were ok (around 65-80c), but suddenly the fans started screaming and the screen went black. When I got it to come on (only got it to come on for a few secs) I noticed the temps on both cpu's were running at over 120c. I shut down Safari and every program I could think of, but the temp remained high. I was afraid of frying my cpus' so I shut it down via the apple menu. The monitor went black, but the fans continued screaming so I held down the power button.
Now when I try to start it up I get the normal ding, but a black screen. When I look through the mesh on the front I see two red lights (I'm guessing where the cpus are). Please help me determine what the cause of this is! I'm a designer and this is my only source of income. Thanks in advance!!!!Well, I've taken it in to my local Mac repair shop. I'm wondering if the coolant is coming from my power supply (which is under warranty and was replaced 2 months ago), or if it's a separate component. I know this is a known issue with the liquid cooled G5s, and I hope that whatever is wrong will be fixed!!
When I was carrying it out to my car to transport today the coolant leaked all over my floor. I had both my dogs indoors and I didn't notice the trail of liquid till I got back (almost an hour later). I really hope neither of them licked up any of it! Between this and the potential fire hazard I'm almost starting to question on whether or not I even want it fixed. I'm literally afraid of my computer..lol.
I should be hearing back from the repair shop tomorrow. Fingers crossed this leak didn't fry my cpus and logic board. At temps like that I don't see how it couldn't!
Thanks to all of you for your help! -
Power Mac Quad fans going into overdrive
Hi,
I've been experiencing some strange issues with my Power Mac Quad G5 recently. The issue seems to coincide when I'm running either one of the three listed programs (FLV2 iTunes, Handbrake or Reel Bean) when they are compressing or converting files. On a couple of occasions when i've left the programs running over a period of time i've come back to find the fans in complete overdrive mode, the screen black and the computer completely unresponsive to any key commands. I have to hold the power button in for 5-6 seconds to shut it off. It re-starts normally and runs fine. Any help would be greatly received.
ThanksHardware monitor is the application that will monitor temps & other stuff (CPU voltages, fan speeds) http://www.bresink.de/osx/HardwareMonitor.html. I used it on my dying G5, the data always ended abruptly when the crash happened.
I think your G5 is doing the same as many others, namely crashing while asleep, then the fans go up to 100% I'd strongly recommend you disable sleep and see if it happens again. My 3 year, 2 month old G5 became useless after one of these 'sleep crashes', I think it is possible for the hardware to become damaged during one of the events, or it is the reason for the 'sleep crash'.
There are lots of threads on 'fans on full blast', 'turbo fans', 'jet fans', 'sleep jet fans'… in the G5 forums, I haven't seen one that has an answer to solve it, but consider stop using sleep & keep an eye on the number of CPU's the G5 boots with, lots of G5's have lost CPU's and I suspect this is part of the issue.

2011 MBP 13-inch 2.3 GHz CPU Temp Issue
Hi everyone!
I am new both to the Apple forum and the Mac. Two days ago, I purchased my very first Mac--MBP 13-inch 2.3 GHz (not customized or anything). I've been playing around with the different applications and researching on different forums about CPU temp. In a quiet room, I can hear the low buzz/hum of the computer. I thought MBPs were pretty much silent? Sorry if this is a silly question, but I just want to make sure there's nothing wrong.
On average, CPU temp is around 49-55 degrees Celsius with the fan running just under 2000 RPM which is fine. When I tried recording my voice through the built-in mic on GarageBand, after about 10 minutes, I heard the fan go on full blast. I checked iStat Nano, and the CPU temp was 91 degrees Celsius with the fans running from 6200 - 7000 RPM. Is this normal? I had Firefox, TweetDeck, and iChat running in the background. Should I only have GarageBand open and nothing else in order for the CPU temp to not become as hot? 91 degrees Celsius is around 195 F so that scared me, and my computer was super hot combined with a really loud fan. Should I call Apple for support?
Thank you so much for your help, everyone!I love Firefox, its the absolute greatest browser in the world I use it myself.
However Firefox and Chrome both are HUGE memory hogs, so you have to be a bit more conservative using them with other applicaiton's open. Occassionally in Firefox you may have to close all open windows and create a new one just to flush the RAM. Because everytime you open a new tab, it asks OS X for more memory and then doesn't give it back.
Also you must remember you bought a integrated graphics computer, meaning the CPU (processor) also does the graphics. This is double duty work the CPU must do and therefore twice the heat in one location.
There is a huge thread on these forums about the overheating 13" MacBook Pro's, perhaps if your a power user or a heavy multi-tasker that your should consider returning that machine complaining about the heat and get a 2.2 Ghz 15" MacBook Pro (or better) with the 1GB Radeon 6750M. It's a MUCH cooler machine and more powerful. I also advise the anti-glare high res screen so there are no reflections in the clasroom or at work etc.
I think you have a 14 day return window.
