CPU temperature going to up 80-85degree suddenly in occasion

it had happened a few times already and shutting down all applications doesn't resolve the issue, is this common or should i seek apple service?
thank you

Yes, would be on the low side °F, it's about that when I first wake mine up (although I use °C as well).
Ok, it may be due to a background process that is running a high percentage of CPU activity. Check Utilities > Activity Monitor > CPU tab, set the pop-up menu to Active Processes, click on the CPU column to sort, and see if anything is using a high amount of CPU capacity. Stuck print jobs, some widgets, etc., can do this.

Mac Pro CPU temperature while rendering

Hey there, I just recently got myself a Mac Pro 2009 with a stock CPU - quad 2.66. While rendering, my CPU temperature goes up to 71C/160F and fans are on their defaults. Im just wondering if this temperature is OK for fans to not kick in, or I should reset something? Thank you

By seeing all the thermal sensor readings, and fans, sometimes people have found an issue where the readings were not right - sensor was getting wrong reading or none -
Laptop like MacBook Pro can often have their fans running much harder to cool and deal with heat.
Those new Haswell chips are suppose to run even hotten, they may be providing Intel 4600 integrated graphics as well as cpu functions, PCIe and USB3 as well as memory controller. They are powerful and efficient - and you will see cpu spikes in utilization AND corresponding changes in temps. \
Same on Mac Pro but not as extreme. Opening apps and files can show 10*C jumps for 1/2 second.
If you are going to render, then sure do what helps the system stay cooler and in a safe(r) temperature range. Newer components are helping companies save $$ on cooling and being able to run servers and even disk drives by 5*C warmer making a huge change. Think Google, Facebook or NSA having large factory flooors housing equipment needing to be kept in temperature controlled environments.

K7N2G CPU temperature - help!

I just built a new system for a friend and after putting it together and starting it up - xp was nicely loading then all of a sudden about 1 minute from the time it was switched on - the whole pc just switches off. Another time I went into the BIOS to configure and while I was changing values in there - it again switch off like about 1 minute of me going into the BIOS.
I can't figure whats wrong - the power supply I first blamed - but its a 350 Watt model and there is only 1 PCI card - two ROM drives and a HD - so no power issues. Then I suspected that it might be some MSI security feature kicking in - the most likely something shutting down the PC because of a high CPU temperature. When I was in the BIOS I noticed that the CPU temp was around 61-63 degrees.
I built my own system (KT4 Ultra FISR MB) about 2 months ago and that CPU same as my friends (XP 2400+) just shows 36 degrees - and my system is fine. I have a Zalman cooler and about 4 case fans - and my system in generally quite cool.
My friends HSF is a brand called Titan which has a copper based bottom plate.
Does anyone else suspect the HSF? Or is there something else on the MB I dont know about or any other ideas?
Thanks for any help.

hi
did you mount the heatsink correct?
does the cpu fan work?
you wrote about a 350w powersupply.what specs?
a q-tec 550w is barely enought for me.
do you have any temp monitor programs running that shutsdown the computer when the cpu gets to hot?
did you use heatsink paste? and how much?
you know bios 3.3 shows to much and bios 3.4 shows to little cpu temp.
xp2400+ is rated for a max operating temperature of 85 celsius
make a signature like mine.
helps alot when people are trying to help you.
bye

K9N Platinum - Wrong CPU Temperature in BIOS

Hi, I have a K9N Platinum (7250-020) with the latest 1.3 BIOS and an AMD X2 3800+. The CPU Temperature in the BIOS has a negative sign in front of it, and it seems to always report -48*C. I tried the latest nVidia nTune and it was reporting the CPU temperature to be 208*C, which is absolutely impossible...
Does anyone have the same problem? I searched around and it seems I'm not the only one, but I still cannot understand if it affects only some K9N Platinums or all...
Thanks.

I assume you are talking about checking voltages as reported by the BIOS in the HW Monitor page, not physically checking them with a multimeter, correct?
I'll take a look at the numbers in the BIOS, but last time I checked they were ok.
As for raising the issue with MSI, eventually I will, even if they ask you soooooo many questions (for good reasons, I know...) that it would take me half an hour to fill that form...
I've checked with both and software is a little out from what a multimeter state's. Only check with a multimeter if your happy to do so. http://forums.extremeoverclocking.com/showthread.php?t=137886 offer good advise if using a multimeter .....
The only issue I see is the AUX connector for 3.3v with ATX2.0 spec (Modular cables etc)

Mac -Mini running at 100C CPU temperature after receiving back from servic

Hello,
I just received back my Mac-mini from Apple service.
As other users reported, the fan was going mad, running at full speed all the time. By using: http://www.bresink.de/osx/TemperatureMonitor.html
I could see that the temperature-sensor connected to the heat-sink did not show up in the list of sensors. Service replaced the main board, and now the heat-sink sensor shows reasonable readings, and the fan is running silent, at least with no work load.
However, while performing a little web browsing, I found that the fan still goes wild.
What I noticed: The "TemperatureMonitor" utility reports that the CPU core temperature goes up beyond 100C/212F, even under mild work load, while the CPU heat sink is still reported at moderate temperatures around 35 C/95F !??? Environment temperature is below 30C.
Before I give away my MAC for another week or two, I would like to check whether this is usual behavior. Other users report max CPU temp of about 80-90C. Intel specifies max core temperature of 100C. According to the digital thermometer build in, my MAC sometimes exceeds this max spec by Intel.
Is this usual behavior, or did Apple service not properly install the heat sink after service, such that the CPU is only running with limited cooling ??
Thank you for your suggestions

Only an internal investigation would show whether the heatsink was correctly reinstalled, but quite clearly since the temperature being reported is at the operational limit specified for the processor, what you are experiencing is not in any way 'usual'. There are sites with content such as flash animations, which can cause high CPU load and thus push system temperatures up and cause the fan to spin up, but not for prolonged periods of course.
Since the fan is running up to full speed on your mini as a result of the temperature rising, it is clearly not an issue with MacOS or the fan control cable, and as such I would urge that you return your system to the service provider with a description of the problem and a list of website addresses you have visited which causes these problems so they can set about replicating the issue.

Why the CPU temperature is so high?

My NB Model #MB466, the CPU temperature is 40-50C under normal running and the fan is 2000rpm (I use iStat). When the CPU usage is about 80%, the temperature goes up to 70 or 80C, I can feel it, especially the bottom area of the screen, and the fan goes up to 4000rpm.
Is this normal?

My new Aluminum MacBook can get pretty hot when I play Spore or use an iTunes visualizer. The hottest I've seen (according to iStat Menus) is 194 degrees fahrenheit and 5637 rpm. I think they won't go too much farther. If something meets the system requirements, it should be fine.

CPU temperature under Bootcamp with Windows 7

Hello,
In Windows 7 on Bootcamp (version 4.0), while watching youtube/flash or installing software (e.g. Adobe Acrobat updates), the CPU temperature on my new MBA (MacBookAir4,2 (13") - 1.7/4/256GB) goes pretty high, but ironically the fan speed does not increase to take care of that.
Attached is a screenshot I took using speccy, where we see that the CPU temperature is 94 C, but the fan speed is only 2001 RPM.
However, when I run OS X (Lion), the fan behaves normally and speeds up as necessary to accommodate the increase in CPU temperature.
Has anyone else experienced something like this while using Windows 7 under Bootcamp? And does this behavior seem normal?
Thanks!
Screenshot:

try Lubbo's Fan control.
http://sourceforge.net/projects/lubbofancontrol/
when you first run it immediately decrease the max fan speed to less than 3000. it's default value is crazy 6000 rpm.

Portege M400 - High CPU temperature

Hi,
I'm having a problem with CPU temperature in my M400 (Vista OS). When I power up computer, initial temperature is around 35C, but after about 15 minutes of work it jumps to 60C and stays there.
Last night reached 80C and that really concerned me. I tried anything from upgrading BIOS (v3.6) to changing power options in Vista.
I don't know if this is actually funny, but a few days ago I placed a pack of chocolate next to cooler (about 10 centimeters away) and after 5 minutes I noticed it started to melt. :(
Please help! Any suggestion is welcome!
Regards,
Jovan

Hi Jayjay,
I haven't experienced any unusual shut downs so far. The only problem was keyboard buttons overheating. After using computer in tablet mode keyboard would become pretty hot.
However, as you suggested, I used vacuum cleaner on my computer and the situation is quite better now. Idle temperature is 44C-47C, while during high performance it goes up to 70C. The good part is that when I leave the computer idle for few minutes it automatically drops down to default 44C-47C (not like before).
Now, I can't be absolutely sure how I managed to do this, but it definitely has something to do with Toshiba Power Saver, which is only like "add-on" to Vista's power management. There is an option that sets CPU to Cooling optimized mode. The down side of this story is that my cooler is really noisy now but I don't care much! :)
Thank you for your help!
Regards!

MacBookPro CPU temperature is over 90 degrees while playing video

Hello
I have MacBook Pro (details are on the screenshots). When it plays video CPU tempriture goes over 90 degrees and fan makes big noises. Is this normal? or should I change speed of fan and make it faster for better cooling?
Thanks
George

90c during video playback is fine. If your temperature went above 100c, I would start to get concerned.

Tested: max CPU Temperature

Well... i have forgotten to turn on my CPU-Fan (for normal purposes like email, surfing, word,.. I always switch the fan to the slowest (quietest) setting in Core Center) and started playing gothic 2.
After 15 minutes playing, suddenly my PC freezed and rebooted. I looked at the health status in the BIOS immediately and it showed me a cpu-temperature of 93 °C !
My system is still stable and the CPU wasn´t harmed. Puh
PS: I didn´t set any shutdown-temeratures in BIOS or Applications. So it must have been the P4-included overheat-protection.

100C is maximum
60-75C under 'normal' loads would appear to be what most people see

785gtm-e45 cpu temperature very hot

hi, i just bought a 785gtm-e45 mobo yesterday (upgraded from a 780g chipset).. After installation,i turned on the pc and noticed the cpu fan being very noisy. i went to the bios and saw my cpu temp hitting 58-60 degrees (reason why the fan is very noisy). my processor is phenom II x2 550. i want to know if this is a normal behavior of the msi mobo before i continue installing an OS. because as far as i know,58-60 degrees is very hot (without any OC) and the recent mobo i had does not even come close to these numbers no matter how much i overclock it. i presume that it has defect, that's why im afraid to go further that could possibly do damage to other components.

ok, tnx for the reply.. i managed to install windows 7 with no problems and cpu temp goes down to 45-50 degrees in windows. but i observed that when i keep on staying in the bios, cpu temp keeps on getting higher and higher up to 60 degrees. also, the cpu locks when i enter the CPU specifications. is this normal?? my 550 was bought 2 months ago (new out of the box). the only thing i bought yesterday was this msi mobo. i bought it because of ACC. im asking these questions because im very surprised with the big difference in temps with my previous mobo to this new one. with the previous one, i managed to overclock my 550 to 3.6ghz (stable) and temperature doesn't even reach 45 degrees (even at a hot weather).

K8T Neo-FSR showing incorrect CPU temperature

Hello. I recently purchased a K8T Neo-FSR, which came with BIOS v2.2 installed. For some reason, it wouldn't allow me to set my own memory timings (it always used the "safe and sane" SPD values, according to CPU-Z, regardless of any BIOS settings I tried). I wasn't about to sit back and let my expensive new memory go underclocked, so following some advice I found on an obscure German forum, I installed the v7.1 BIOS from MSI's global site. That fixed the timing issue, but now the board is reporting incorrect temperatures for my CPU. It usually fluctuates between 23-26c, but will occasionally rise to nearly 30c and then immediately drop back down again. Case temperature remains stable at 27c. When I first installed the board, the temps were right around 45c, almost 20 degrees higher, which seems a lot more accurate to me (though this was also before I upgraded the crappy heatsink).
Is this anything to be concerned about, and is the CPU temperature supposed to constantly fluctuate like that? I'm worried that if my fan fails or something else goes wrong, the sytem won't react until the temperature is 20 degrees OVER the safe limit. I have a feeling it interferes with the Cool n' Quiet functions, too, though my CPU fan (Thermaltake Venus 7) has its own built-in sensor and adjusts itself automatically anyway.
Aside from the temperature wackiness, the system is rock-solid and runs like a dream. Specs are in my signature.

There are 754 Venice's out there as NewEgg sold them at one point from what I gather as I was looking at what was the best 754 but settled for the Clawhammer.
I have just stopped using CoreCentre on my XP as it started to show extremely erroneous and frightening temps so I ran MBM5 in conjunction as well as used my Cases thermal probes and guess which one was wrong...?
This was after seating and reseating the cooler, CPU, memory many times and it was only on Asetek's forums that reminded me that I should maybe do some independant tests by taping probes on the cpu's board as close to the core as poss, a difference of twenty degrees no less.
CoreCentre seems to have got a bit lost and a tad annoyed as I cross checked after buying the components for a 1/2" inch custom watercooling setup.
Now this is the current temp and voltages I get:
The 45 degree high was me using Prime to "cook" the thermal paste as I had to reseat the Artic Freezer 64 as it had dropped a touch.
My ClawHammer is for some reason one of those that never had a heatspreader which of course leads to difficulties with such coolers as the Freezer 64 Pro. Does anyone know where I can get another spreader or should I just leave it...?
I am not going to o/c this CPU to be honest, since sorting the temps out and once the watercooling is on, 3.2Ghz is plenty good for me for the moment and bearing in mind the Neo's touchyness about settings in BIOS I am very much considering now to roll back the BIOS to 1.9 as it was 2.2 that started causing the problems.
As for the memory timings, my Neo is totally ignoring any attempts to change the timings of my memory, I had to part company with my XMS Crucial sticks because the Neo had all sorts of problems and running some of the best memory at DDR200 was pointless.

Abnormal CPU Temperature!?!

Hi all,
Recently built a new system based on the specs shown in my signature. Everthing seems to be installed correctly and when I was in BIOS, the CPU temperature was sitting at about 52 degrees C while system temperature wasn't much over 30. After installing Windows, I installed some of the MSI utilities on the CD that came with the motherboard, including PC Alert 4. I also installed my Graphics Card drivers and restarted my pc. After the restart, PC Alert popped up and I had hardly had a chance to watch the pretty fan animation spinning when I noticed the CPU temp was on 68 degrees C and then suddenly jumped to over 100!! The next second a dialog box popped up saying there was abnormal cpu temperature and that the pc would shut down. I left it overnight and then retried in the morning... The exact same thing happened... as soon as Windows had started up. Obviously I shut down at once, but am baffled as to why this is happening. I haven't had a chance yet to recheck the BIOS temperature readings, but I'm pretty sure that they will reflect a more normal temperature.
Any ideas as to what could be wrong? Is PC Alert 4 compatible with the MSI 975X Platinum PowerUp Edition motherboard? Could my PSU be too small (even though all the fans appeared to be spinning when trying the above)? Might it be an actual airflow/temperature issue, or could PC Alert be wrong? Any help would greatly be appreciated. Thanks in advance.

Hey I have this same problem I uninstalled PC Alert but the amusing thing is that PC Alert tells me my CPU is 168C and then Speedfan tells me it's -122C.... lol does anyone know a reliable program in which to check the CPU temps?

Coretemp reads the temps directly from the cpu and not from motherboard sensors.

Weird CPU temperature problem

Hi everyone.
The first time I run my system in the morning, I'm having high CPU temp readings by Core Center: 71 C, at around 40% CPU usage, running Norton Antivirus '05, and 67 at iddle. In the same conditions, Motherboard Monitor 5 reads: 67 C for N. Antivirus and 63 C at iddle.
So, I restart computer and check BIOS's PCHealth Status. It reads 46 C for CPU temp.
Then I get back to Windows XP (SP2), Core Center reads CPU temp while running N. Antivirus as 53 C, and MBM reads 50 C at 40%-80% CPU usage. At iddle, Core Center reads 49 C, and MBM5 reads 45 C.
Environment temp is about 30 C.
What do you guys think is happening? Do I need to worry about it or not?
Thanks in advance for your input.
My System:
Windows XP PRO (SP2)
MSI K8N Neo 2 Platinum BIOS 1.30
Athlon64 3800+ no OC

I was having the same problem as described by the forum user. Despite my laziness, I even unhooked my CPU fan clean the fan and the CPU and put it back together with Arctic silver. This helped the idle temperature at START up from 50 degree C down to 43 degree C reading from Core Center. However, eventually the CPU temp will creep back up to 47 to 50 degrees C.
My breakthrough came when I read one of the thread which said to uninstalled Core Center, once I done that, my CPU temperature at Cold Start and Warm Start seemed to be consistent at around 36 to 40 degree C (I used SpeedFan 4.18 to verify my temp readings I even crossed check the temp reading with SisSandra 2005 and the two readings are consistent).
I then installed CoreCEnter 1.7.1.0 back and during cold start the temperature will creep back up and keep on increasing. Once I do a warm start everything is back to normal again. So after cold start I open both SpeedFan and CoreCenter side by side and I notice the following:
During cold start, CoreCenter never starts the CPU fan at max RPM, it starts around 2200 RPM or so. Then it would start loading the CPU varying from 1 to 4 to 100% (this happens intermittently so you won't see it if you are not staring at the screen), which would increase the CPU temperature (this is observed in the SpeedFan monitoring screen). Then it would lower the CPU fan back to 1850 RPM or so and does not increase the fan speed even when temperature goes back up. The problem does not seem to exist when one does a warm start then CoreCenter lets the fan stays at maximum speed and the temperature is stable.
I noticed when I downloaded the new CoreCenter version 1.7.1.0 software from the MSI web site, it said "fixing fan speed never reach maximum problem", so I believe this is a CoreCenter software bug. BTW, I just went back to the MSI tech support web site; it no longer showed this message. I have a feeling that they removed the message from potential liability with high temperature issue that might have led to many MB returns. (I know this is sounding awfully like a conspiracy theory)
This is my conclusion:
(1) CPU temp reading from core center is accurate minus about 3 to 4 degree C cross checked again other utilities. (If you system reaches 60 to 70, I should still be alarmed, do not just let the system idle, because it could be an actual reading minus 3 to 4 degrees).
(2) CoreCenter never let the fan reaches maximum speed during cold start and will load the system gradually therefore increase CPU temperature even more.
(3) After warm start, Core Center goes to normal and let the CPU fan goes back to maximum speed.
I know this is not a very scientific observation, nevertheless it is reproducible on my system. Please note that I have a Neo Pla set up not Neo Pla 2 therefore results might be different if you have a Neo Pla2 set up. I really doubt that would be the case since CoreCenter only has one version for both motherboards.
Please give this a try and see what you find, I am curiously to see what other gets. If we can all produce the same issue, perhaps MSI will come out with an updated version of CoreCenter again.

K8N Neo2-FX new CPU temperature problem

Well, I'm not sure if this problem is unique, but I didn't find any help by using search or google.
Problem is this: CPU temperature keeps going up slowly but very persistent and then the computer shuts down about somewhere between 80-82 degrees Celsius (says BIOS). Heatsink is warm when is touch it, i would say the CPU is max 40-50 degrees "hot". CPU is 3500+ Venice. These 2 are brand new parts. BIOS version is 1.B.
Computer was running fine one evening, night and morning (about 10 hours) with Windows XP, and then all started: shutdown. I waited couple minutes, re-started, went to BIOS H/W monitor. Temperature reading was about 50, then it was slowly rising to 80 degrees and shutdown. I instantly restarted and went to BIOS. Temp was about 70 and rising. I shutdown it manually, touched the heatsink and it felt perfectly normal (warm). I'm using the boxed cooler that came with the CPU. Fan speed is about 3150 rpm.
Right now only attached parts are PSU, MB, CPU, AGP card and 512MB DDR so I just can go to BIOS and check the temp. I have tried different PSU, AGP card and memory, the problem stays. It always starts from a reasonable value: 25 degrees after being down for a while and higher if i have tried it on. It takes about 2 minutes to go from 30 to 80 degrees.
Is this a sensor problem, CPU problem or what? One more notice: Motherbard monitor gave strange temps in Windows. Most of the time it was OK (50-55), but then both values were 0, and then back to normal. I noticed the zero values before the 1st crash too so this can be a sensor problem.
Installation failure is not possible, i have worked with computer HW over 10 years. I removed the heatsink, put it back and it fits perfectly. There is no way the CPU is 80 degrees hot. I've touched thousands warm heatsinks.
Should I send the MB/CPU package back or do you have any tricks I can try?
Thanks for reading and sharing my pain

Quote from: inf on 26-October-06, 14:57:17
I didn't change the thermal compound when I removed the heatsink. I checked that it is OK, some sort of gray grease, but not anything compared to arctic silver, but not a rubbery "pad" either.
Like I said that original compound is a one shot deal. It needs to be replaced... with the same material according to AMD for warranty purposes.
Quote
- I decided to start the computer to Windows, everything seemed to be ok, MBM showed 42 degrees about 1 minute. Then it got to 45-46 and stayed there.
- I downloaded the SpeedFan and installed it. Core temp 45, Vcore 1,40 - 1,41V. Stared the screen couple minutes, stable.
- I decided to try with a load. I Started 3DMark2001 for 5s and shut it. Core temp was 65! Very fast peak Then it went down to 53 and the weird dance began... 53-63-54-64-54-64-53-63... with the same rate than SpeedFan refresh rate. This state was stable now, I stared the screen 5 minutes and the graph showed 10 degree peaks all the time, fully idle CPU.
- Another start with 3DMark, now 30s and i halted it. 80 degrees! Heatsink was as warm as normal heatsink can be in idle computers. And then it went back to 53-63-53-63 dance.
- 15 minutes passed and I decided to boot to see BIOS values.
Weirdest part: BIOS is showing 67 degrees, rising 1 degree/ 2 secs to 80 and shutdown Vcore 1,37 - 1,39.
Conclusion: Windows is more stable than BIOS In BIOS it raises the temp to 80 and crashes, but in Windows I can do surfing and normal work and the temps stays reasonable as long as I put minimal load to CPU.
Like Syar said, CPU "halts" in Windows will result in lower temp.
Quote
Now I really think there is some kind of sensor failure. 10 degree dance in idle state is not normal. Fast peaks are normal if the heatsink is not touching the whole CPU (core) surface, but in this case it's fine. Crashing in BIOS is 1st time for me if the computer is idle stable in Windows. I'm sending both back, CPU and MB.
When you get the 10 degree jump, what does SpeedFan show for CPU usage? Also Look in Task manager/Performance to see what the CPU graph looks like and if you run Process Explorer from www.sysinternals.com you will be able to see which process is using CPU. It sounds to me like there is a process which is running at some interval and that just a small amount of CPU usage is boosting temperature excessively. Before giving up on it, I'd recheck heatsink fitting with fresh thermal compound -- a good heatsink paste, like Artic Silver will be sufficient -- to be sure, before giving up on it.
