100 degrees + Normal for CPU temp?

Apple recently replaced my logic board for the 2nd time in my SR MBP- now under a load (generating previews in Aperture, Rendering in Compressor or FCP) it runs at 101-104 celcius- with the occasional crash. I havent seen it go 105 as the machine shuts down (with fans at 6k). As I recall, my first run logic board never went over 99.......
Apple genius wasn't able to replicate the issue, and they are telling me up to 107 degrees is considered normal and acceptable. Can anyone shed some light on their temps? Should I press back on this? I routinely do 8-13 hour renders, and it kills me when I have to start over.

I should probably also note that since the most recent LB replacement (and the higher temps) the battery swelled up.
So far they have told me the battery is the only thing they have found wrong.

Possible fix for CPU temp problem found.

Well, one day I decided to take the heatsink off of the nForce3 chip and put some good ol' Arctic Silver thermal compound on there. I figured it might help with overclocking and whatnot. When I took it off, look what I found(!):
Imagine my surprise! Why did they even bother? Ridiculous. After removing their mistake, I put some Arctic Silver on there and re-attached the MSI heatsink (someday I'll probably buy a much better one for it). I've noticed after a couple of days (it takes a little while for the thermal compound to set in) that the CPU temp doesn't appear to fluctuate wildly anymore. Before I was getting crazy jumps from 45C to 65C, but now it hovers around 45C-47C idle and a little over 50C stressed. I've also noticed that my overclocks are a bit more stable now too. For those of you wondering, I'm using BIOS v1.1 at the moment (haven't tried v1.42 yet).
Can anyone confirm these findings? Maybe something else I did fixed my CPU temp issue (I do fiddle with the BIOS quite a bit). My guess is that the nForce3 has a part in determining/reporting the CPU temperature.
I hope this actually is a fix for some of you out there, but don't get your hopes up too high until at least one other person can confirm my theory.

It's very easy to remove the MSI plate. Using a pair of needle-nose pliers pinch the fins on the heat sink on one side together (one at the top, one at the bottom). You don't have to do it too much and be careful. This provides enough slack for the plate to drop out with some slight assistance. Well, that's how I did mine.
I then attached a 40mm fan by screwing into the gaps between the two fins. Only on the one side mind (so 2 screws in total). It holds the fan fine, no rattling.
I have some Artic Silver adhesive and I did consider leaving the MSI plate in place and fixing the fan to it. But I wasn't sure how secure it would be. Plus the plate rattles already, imagine how it would behave with a fan stuck to it.
Unfortunately, I forgot to make a note of the NB temperature before I did it. And I can't for the life of me remember what it was. So I can't say, for sure, how it has effected the temperature. I'm sure it has though.
I suppose it's easy enough to disconnect the fan to find out. I might try that later...
Running at 230x10 (stock = 200x10), MBM reports:
Case = 37C
CPU = 35C
Sensor 3 = 49C
The sensors are labelled by MBM, so I am assuming they respond to the correct items, ie the CPU temp is actually the CPU temp.
This is after a hour or so with Azureus running, mIRC open, a couple of IE windows and SETI running at ~97% CPU
When I take the side off to disconnect the fan again, I will take a picture.

Cpu over 100 degrees celsius

Hi
just got a new macbook, late 2008, and encoded 3 vids to play on sons ipod. Not until the 3rd one when i had everest installed, (using xp under bootcamp), that i noticed the cpu temp rise to and maintain a value around 100 degrees celsius. i have taken steps via software (smcfan and that tweaking software that goes with it) to increase fan speed uunder xp. Should i be worried that my macbook will have a shorter life span considering i had it at 100 degrees c for bout an hour? (Also, Is this a fault in my particular macbook, ie warranting a replacement?)

Hi,
My name is Harris and i am an Apple Store Genius.
100C (212 F) is the hottest that the CPU should go. Pao1250 is right in saying that it will shut down. But when it gets to the point where it will shut down, some damage may have already been done. If you encode videos and it goes to 100, that is fine. As long as you cool it down after not to long of a period of time. If it goes much more above that, bring it to one of us at the genius bar.

PowerMac G5 DP CPU temps?

Hello all,
I am curious to get some feedback in regards to CPU temperature of the PowerMac G5s out there and whether or not I have an issue with my machine and should take it in to the Apple Store.
I have my processor performance set to 'Highest' to minimize the fans going into overdrive (aka 'takeoff mode!").
At idle, my CPU temps read:
CPU A: 57.2/135.0 (ºC/ºF)
CPU B: 69.6/156.2 (ºC/ºF)
However, if I start taxing the system they jump up considerably, and there is an even greater gap between CPU B's temp over CPU A.
These are the extremes I have gotten when running the processors at 100%:
CPU A: 64.4/148.0 (ºC/ºF)
CPU B: 88.7/191.7 (ºC/ºF)
As you see, it jumped from 12ºC warmer up to 24ºC. Is this a serious issue to worry about? I have cleaned out the case and checked for any coolant leaks of which there are none visible. From other research online, it seems normal for the temps to be off +/-5ºC, usually with A being warmer than B.
Would a Thermal Re-calibration at the Genius Bar help things? I would just like to check others experiences and see if this is something I should pay closer attention to and in more detail.

Thank you for the links. It does seem like it's going to run a minimum of $800 just for the processor anywhere I look. What worries me about that is still having the liquid cooled system and the many issues I have be reading about lately with them.
As a designer, actually I have had LCD monitors for over 4 years now at every job I have had. I also use an LCD at home. I actually prefer them. I know there are color differences, but they have come such a long way that I'd hate to go back to a CRT again, so big and bulky. Again, this is just my personal preference.
I do love my PowerMac which why I am disappointed with the issues I've had with it. Not little issues either, the most expensive issues. Plus, with the new OS Snow Leopard possibly dropping the PowerPC line, I'd rather be looking ahead versus treading water with another used PowerMac, even if I could save and reuse all the extras I've put into it.
The more research I do, the more I am leaning towards the iMac 3.06GHz model and max it out to 4GB with aftermarket RAM. As long as I can get 1-2 working years out of it, I can then hand it down to my wife and then make another serious investment into a new MacPro.
I know you can't expand the iMac, other than adding more RAM, possibly putting in a larger HD. Although I have a 160GB in my G5 that I use maybe half of. I also have a LaCie 250GB external where I store most all of my things, so a 500GB internal on the iMac would be plenty for me right now.
As she is a very basic user (internet, music, word processing, etc.) she would still have plenty of computer after it being only 2 years old. She uses my 6 year old Ti PowerBook G4 now and it suits her just fine. (+mini rant here+...how is it my laptop which has traveled many miles has lasted twice as long as my more expensive chained to a desk in a controlled environment machine!?)
As she is finishing school working on her RN degree, I think the iMac is the best case scenario for now (very limited budget) and then when we can save up the extra cash, I'll just get a whole new system. Plus I'll be able to use her to get a student discount and save a few bucks and get a free iPod touch!
As for the Mac Genius, he told me it would cost $85 to run diagnostics as I was out of warranty. He ended up not running any as he told me based on everything I had done and the results I had gotten from my own hardware test, it would only indicate the same results there and doing the re-calibration would not fix anything.

So, in conky I had to change;

And (b) just for reference, I now have two options for cpu temp;
CPU temp option1:$alignr${hwmon 4 temp 1}°C
CPU temp option2:$alignr${execi 10 sensors | grep ^temp1 | tail -n 1 |awk '{print $2}'}
Thanks for all the help everybody.

CPU Temp Idle/Load Difference

need a few second opinions here. below are my cpu temps (using speedfan, MBM5, and prime95):
w/o CnQ:
idle: 35-37
load: 50-52
with CnQ, w/o SmartFan:
idle: 35
load: 53-54
with CnQ & SmartFan (target 40%, tolerance 5):
idle: 31-32
load: 51-52
as you can see the only difference CnQ has made is in my idle temp, which seems pretty good to me, and is actually in the lower range of most of the quotes i have read on here. my question is, should my temp on load be as high as it is? that's a 20 degree difference, and it usually shoots up to the high 40s within a matter of 3-4 seconds and thankfully doesn't go TOO much further. should the difference between idle/temp really be so great? i would have expected my load temp to be a little less than that, maybe the high-40s, maybe even the mid-40s. there's no overclocking here, folks. not a whole lot of tweaking going on.
i've checked to make sure CnQ is functioning correctly, all signs point to yes. i made sure i applied a correct amount of AS5 - i read enough stories about people applying too much so i kept that in mind when using it. i can't imagine that i may have still needed even less than that. besides, my idle temp would have been way higher if i had misapplied, right? my only problem is with the load temps. i've tried several of the recent bios revisions but disappointingly i see very little difference if any in temps i am getting through bios or speedfan. besides, my bios usually reads 41-44 degrees (that should be idle right?) so i don't even pay attention to it.
is my load temp something to be worried about? if not, is it something that could be improved upon? should i get some kind of temp sensor and give it a manual test that way? not sure how to go about doing that or where to pick up a temp sensor. also, my NB/sys temp is usually hovering in the low-mid 40s but that's because i never thought to get a chipset cooler, which i have subsequently ordered from compUSA (i hear compUSA's FMI chipset cooler is recommended). could taking down the chipset temp a few degrees affect the CPU temp by chance? are there some other BIOS switches i should check out and experiment with? i am not a newbie to computers generally, but i AM more of a newbie tweak-wise.
with the purchase of my new system, my first one put together from scratch (and hey, everything's working fine so i must've done a decent-enough job right?), i have really had to take some crash courses in BIOS issues, upgrading, the whole CPU fan and thermale compound market, which i never even knew existed. my previous system is a 400mhz p2 so you can imagine i pretty much had to get an update on the entire industry as it stands to know what i was doing! hey, i even got a BIOS savior to shield me against corruption, etc. nifty little piece of tech stuff.
all suggestions and recommendations would be greatly appreciated. i would optimally like to get my load temp down to mid/high 40s range. perhaps i'm expecting too much here?
thanks,
kevin

The short answer is that cnq will not affect your load temps, since when loaded, it is effectively running exactly as it would without CNQ.
Yes, the temp will "shoot up" more when you go from non-loaded to loaded with CNQ, simply because it is starting from a lower temp to begin with.
You will learn not to trust corecenter readings eventually - they are by no means guaranteed accurate.
If you put your finger on your cpu heatsink when under load - if it's fairly warm, that's ok - if you can't hold it there for 10 seconds without burning, it's too hot.
Edit: I see you were using speedfan - same comment about accuracy applies.

Mid-2009 macbook pro high cpu temp ( 100C) after every cold boot

Hi everyone,
Every time I cold-boot my MBP, the CPU temperature sky rockets to 100C within 3 minutes at idle with the fans barely kicking in until that point. The activity monitor shows 97% idle with no major processes running and this issue is reproducible every time I turn on the computer. However, if I immediately reboot the computer (warm boot), the computer runs normally (~70C CPU temp, fans @ 2000 rpm). If I do a SMC reset, the computer boots normally for the next immediate single cold boot but symptoms return thereafter. The only way to prevent the high CPU temperatures is to do a SMC reset before ever cold boot.
I'm wondering if someone else has had these symptoms with their laptop and how they fixed it. The system is still under apple care and the symptoms are reproducible but I'd rather not bring it in as this is my daily-use machine.

Hardware Monitor 3.7 & CPU temp

FYI,
The newest version on Hardware Monitor (version 3.7 from Marcel Bresnik) now supplies its own CPU temperature monitor extension and no longer relies on SpeedIt, it supports monitoring the CPU temp of both cores. No it doesn't support the throttling capability that SpeedIt was or is supposed to but it at least accesses the real CPU core temp.
As much as I thought SpeedIt would be cool, it just hasn't lived up to its potential and is a development mess. I've been using HM for awhile and love it, had to rely on SpeedIt for CPU temp for awhile, gotta love this new version.
Cheers,
Peter

Hey thanks for the heads up Peter. It works beautifully as you say..

Normal CPU temps?

Hey guys.
I was wondering what is the "normal" temp that my Athlon XP 2500+ Barton should operate at? According to my PC Alert 4 prog the system is between 113 and 119 degrees and the CPU is 89 to around 92 degrees despite this being fairly warm weather here. What are optimum temps to be operating at and what is the default alarm warning setting on the K7N2 Delta-ILSR mobo that I have?
Thanks
Mike

Hi Mike,
Hows the new computer running? First of all PC Alert is unreliable as you can check out by comparing it's temps to what's actually displayed in the bios. Here is a link to speedfan which is much closer to the bios numbers. Your CPU will come up as temp2 and you can also display it in your taskbar so you can keep your eye on your temps. http://www.majorgeeks.com/download.php?det=337
Your temps on your CPU should normally be in the low to mid 30's C and @ 40C under 100% load. I have 6 fans and run 27C to 29C idle And near the middle 30's under full load. One of the six fans is blowing cool are in from the side of the case in a whole I cut directly over the CPU, that and equalized air flow is why I have such low temps. People get freaked out about their temps but actually anything under 50C should be safe. I have run machines hotter than that for long periods of time (years) without problems.

MBP 2.33GHz Core 2 Duo, CPU temp constant 90 degrees C at high load

I have a 2.33GHz Core 2 Duo MBP. Not sure which chipset, but not Santa Rosa. I'm still running 10.5.2 because I don't want to stop the process I'm running at the moment.
Anyhow, I'm running both CPUs at full load, and the program I'm running is very SSE-heavy. iStatPro reads the CPU as running at 90 degrees C with the fans running at about 3800RPM. It's been running like this for several days straight because this is the fastest compute hardware I own. I have three PC case fans pointing at the notebook, so the exterior is relatively cool, as are the other temp readings, but the CPU temp makes me nervous. Various things I've read suggest that about 85C isn't so healthy for the processor. Is that true?
I did try calling Apple Care, but they basically blew me off, suggesting I use external cooling. I could take it to the Genius bar, but that'll be a good 3 hours of my time, so I need to make sure it's worth it.
Comments?
Thanks.

See this article regarding runaway applications:
http://docs.info.apple.com/article.html?artnum=304882
and use that technique to make sure that no other heavy applications are crashing the party. There will be a number of smaller system apps and processes running; you're looking for a big hitter that you did not want.
I hear that the MBP is good for 100°C/ 212°F. I'm a little surprised that you're getting only 3800 rpm at 90°. Fans should be able to turn up to 6000 rpm. You may wish to download smcFanControl.
I use that program to increase the resting rpm from 2000 to about 2500 to give a head-start on any heat issues. At 2500, the fans are not noticeable unless I put my ear an inch from the the computer. The program also has a quick-change setting that lets you quickly bump the fan speed to the max of 6000 if things get too hot too fast.

CPU TEMP 30 DEGREES HOTTER AFTER 10.6.3 UPDATE

ok i found the culprit...using activity monitor.. i discovered that apc powerchute was utilizing 99% cpu.. so i quit the process and my temps immediately decreased to under 100 deg. F. i then proceeded to use their uninstall script and remove the program entirely. all temps are now within normal ranges as i have observed them. not sure why the update was related to this.. or what triggered it.. but all is well..

CPU Temp over 100 C with only iPhoto Open on Late 2011 MBP

Hello All,
Vital Stats: OSX 10.8.2 with 2.5Ghz Core i7 and 4GB DDR3. 7200 RPM standard HDD
What's Happening:
Since Upgrading my Late 2011 model Macbook Pro to Mountain Lion 10.8.2 and the latest releas of iPhoto, CPU temps jump to 100 deg Celsius and fan speed maxes out at 6200 RPM when iPhoto is opened.
Reference: Temperature Readings provided by the program Temperature Gauge v3.5.1
Please Note: This Macbook is done Indexing Spotlight since the upgrade and no other resource hogs are running as verified by Activity Monitor
A "PRAM" Reset has already been performed.
This "Overheating" Should not be happening - Yes I know true overheating is when the intel chip shuts off, but Underclocking/High Temps under such a minimal load is not normal to me. Please Help.

I can see that by mistake I miscategorized my question:
Moderators, please delete the question.
Thanks

A process by the name of avgcmgr is loading the CPUs by up to 100 percent. At least 5 of them have appeared on the activity monitor. I've removed them with forced quit but they return! How do I permanently get rid of them? CPUA temp is now 194F.

Hi Ray-
I'm having the exact same problem and have searched the web for hours looking for a solution (multiple spawned avgcmgr processes that consume cpu).
Did you find any solution?

How to get into BIOS of Sat P200D? What is correct temp for CPU/VGA load?

I tried everything, pressing ESC after power-up,F1, ESC/F1, F2....i cannot get into the bios.
What is the proper procedure to get into the BIOS? I used the latest BIOS 1.70 from Toshiba homepage, i remember i didn't have this problem with the older bios.
Furthermore, what are correct temps for the CPU under extreme load as well as VGA testing with OCCT/Furmark or everest?
If i run OCCT (extreme CPU stress test) i am getting some extreme numbers up to 95 degree on the CPU...
Thanks!

*SOLVED!!!*
It was indeed the case that any standard VGA resolution (like bios screen and bootup screen) was not displayed on the laptop!
Thats why i only saw a black screen!
I plugged an external monitor on it, and i see i am actually in BIOS.
So i went into the BIOS (using the other monitor) and changed the the setting "Analog + External", and now it works and i also have the toshiba logo back and everything

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!
