CPU Temperature of 15" MBP

When I run football manager, or iPlayer desktop, my MBP constantly runs with a CPU temperature of more than 100C.
The genius bar have said that the operating temperature is 25-85... and yet tell me that this is too high. Is anyone else having this problem?
Knowing someone whose MBP actually caught fire has made me reluctant to believe Apple when they say this isn't an issue!
Also, has anyone with a MBP bought in Sept 07 (ish) also been through 3 batteries due to them being "bad" according to an Apple test rather than "consumed"?

Welcome!
The general temp numbers posted here by experts more knowledgeable than I point to ~100°C (±5° or so depending on MBP variant) as being the point where the MBP does a safety shutdown to prevent heat damage to the CPU. Fire is not the issue; the kindling point of the internal components is far higher than the boiling point of water.
There are several things you can do to mitigate heat issues:
1) See if any background processes are eating up CPU cycles. Quit all running user applications so the computer is at normal idle. Find Activity Monitor in Applications > Utilities and launch it. If you've not run it before, change the "Show" pulldown at the top of the AM window from its default of "User Processes" to "All Processes." There is a column for "%CPU." Click that column header to sort by CPU usage.
If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated.
2) Make certain your physical arrangement of the computer and your usage patterns are not contributing to overheating. Apple recommends against using the MBP on your lap or any surface that contacts the case bottom. The case bottom is part of the heat dissipation system and needs need air. If you need to use the computer in your lap, make a simple lap board from scrap plywood. The height of the rubber feet is usually enough to let the air move but, if you are playing graphics-intensive games, you may want to insert some 1/2-inch (13mm) spacers.
The main exhaust vent is under the display hinge on the back panel of the case. It must not be obstructed.
Here is an Apple article on temps but it does not list critical temps fr any model:
http://support.apple.com/kb/HT1778
3) Run Apple Hardware Test (AHT) on your install/restore disk that came with the computer. This can see if a fan or temp sensor is not working. If you get an error code, post it here and someone can translate it.
As for the battery on a late 2007 MBP, I'm on my second. Mine started throwing out highly variable "remaining capacity" numbers at about 11 months and ~25 cycles. It turned out the battery was starting to leak and it was judged "defective" and replaced under warranty. Inspect the edges of the battery at the seam that join the cover to the case. I found a spot that looked like grey-blue papier maché stuck to the seam. It was the goop from inside the battery.

  • Temperature widget for MBP

    I've seen it around here before and cannot locate it now. Can someone post the link for the cpu temperature widget that works on the MBP? Thanks

    There are a couple threads re: the temperature widget. This is where I downloaded the app:
    http://www.bresink.com/osx/TemperatureMonitor.html
    It works if you have a Seagate drive. Something about SMART technology that monitors the temp of the drive. Mine hovers around 94-95F

  • CPU temperatures while gaming

    Hi!
    I'm getting CPU temperatures of 90°C to 99°C while gaming. Should I be worried or is this normal?

    Forgot to mention the specs. I have a late 2013, 15-inches MBP, with 16 gigs ram, and the Nvidia 750M graphics card.

  • Faulty CPU temperature sensor

    Hello,
    I am sorry if this is covered already in another topic.
    Today I went to the local Apple service center to give my MacBook Pro 15 (OS ver. 10.6.8) for maintenance cleaning and a change of the thermal paste of the CPU. I got a call a few hours later and a technician told me I need to change my mother-board, because the heat sensor of the CPU gives incorrect temperature and the FANS start spinning at 6200 RPM without the processor to be loaded so much. (The price was too high ofc)
    Well I know that if I start a graphic software or a game then the temperature and the fan speed rise but thats perfectly normal and logical. Though I have seen it many times the moment I start a game, temperature softwares like: Fan control or IStat Nano show around 30 or 40 degrees increase for just a few seconds which is not possible. And vise-versa the moment I turn off a game it drops to 50 or below degrees. I tried something else - turned on the laptop after it was cooled down to normal room temperature and started - Parallels Desktop /Windows XP then Heroes of Might and Magic V and loaded a saved game without actually doing something, just to check the sharp increase of the CPU temperature...it shows 108 degrees, though the body of my laptop was perfectly cool (where the CPU is placed). I think is impossible to generate such heat in just 2 seconds. The interesting thing is that the moment you stop it it drops to 45 degrees.
    Please advice if you have any ideas. I can not afford to change my MB at the moment and the laptop guarantee has expired 1 year ago.
    P.S I was thinking to increase the upper threshold of the Fan Control (now is set to the default of 80), though I am afraid to speculate with this...

    If your cpu tries to exceed it's maximum rated temperature it will immediately shutdown (crash). 
    Just because you have Parallels at full screen does not mean that other applications stop running.  Everything that was running before you went to full screen for Parallels continues to run in the background.
    Graphic intensive games can put a very large load on the cpu.  They can also draw power from the battery while using AC power.
    Your fans should be idling (2000 rpm) when the temperature is less than 70 degrees C.  Somewhere between 70 and 75 C they should begin to speed up.  A 100% sustained load on the cpu will have the fans at maximum rpm as long as the load continues.  If your MBP can handle this sustained load without shutting down the heat transfer from the cpu is correct. 
    It is very unlikely that the temperature sensor for the cpu is bad since it's part of the cpu chip.

  • 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)

  • Tweak the balance between fan speed and CPU temperature / Dell M6400?

    Hi all,
    I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

    When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
    I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
    Aurel.
    PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

    Hi aurelieng,
    I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
    My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

  • My macbook pro cpu temperature is too high??please tell me correct fact and information

    i mistake deleting my activity.......re question...
    I'm using macbook pro retina 13inch 2013 late version.
    my macbook has NO external graphic card, just iris graphic.
    when i was playing diablo3 or watching movie by using bypass ip address, my cpu temperature was maintained 90~100 celcius degrees.
    And at the same time, my cooling fan was maintained 5800~6000 rpm.
    There are two questions.
    One, is my macbook temperature too high or normal level ?
    Two, i know that 6200rpm is maximum speed of cooling fan. Why  did fan run 5800~6000rpm, not maximum?

    When processor intensive activities are taking place, temperature may reach the maximum level.

  • CPU temperature is too high in Solaris 10 sun fire v890 machine

    Hi,
    I just installed Solaris 10 on a sun fire v890 machine. I used the prtdiag -v command to check the system.

  • Satellite M100 - I can't analyse the CPU temperature

    I'm an owner of Toshiba Satellite M100 series (Core Duo T2300, X1400, etc.). The problem is that I can't analyse the CPU temperature changes in such popular application like Everest or Notebook Hardware Control. Also any other software provided by Toshiba and already installed on my HDD doesn't include some CPU diagnostics including the temperature changes!
    The only software which seems to be working is the HWiNFO32 so there is some thermal sensor inside which reads this temperature of Centrino Duo processor, but this software is not very user-friendly :(
    There is a request for Toshiba to do something with this... I've upgraded BIOS in my model to a version 1.70 but it didn't change anything I could easily notice (or is there any?) :(

    Hi
    Like Mike said the BIOS update has nothing to do with the CPU temperature monitoring.
    The fact is that Toshiba doesnt support any 3rd party applications.
    However, all the temperature programs are not precise and dont get exactly information about the temperature. Only the programs with a physical temperature sensor will give you a exactly temperature.
    I dont understand why its so important for you to know the temperature. The Toshiba notebooks support an overheating protection and if the temperature increases to the critical level so the unit shuts down automatically.

  • 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.

  • Mac Pro 8-core X5365 CPU temperature

    I've got an 8-core Mac Pro which is crunching SETI@home 24/7, with Hardware Monitor monitoring the CPU temperatures and other vital stats. After reading the Intel Quad-Core Xeon Proc datasheet, I'm a little edgy about the operating temperature of these X5365 CPUs, currently registering at 65 - 70ºC on load for each temperature diode, and fail-safe temperature set to 73ºC to disable SETI@home via Hardware Monitor. I also have smcFanControl speeding up the fans because my ambient temperature varies thanks to myself being in a tropical region, my ambient temperature can reach 33ºC at times, but down to 28ºC when air-conditioned.
    My question is, what is the maximum temperature for these CPUs before they run into the risk of being fried/permanently damaged..?
    Inputs from the Mac Pro-DC/grid community are also welcomed here.
    Thanks.

    my 8-core is running seti 24/7 since may without any problem, although my ambient temps dont rise above 30 degrees centigrade...and that's using the optimised apps which make the processor run hotter
    the fans on the machine run 600-2000 rpm all day and all night, i dont expect it to lessen the life of the machine whatsoever. it should be capable of running flat out all its life, that is, after all why we spend so much on these machines in the first place !
    if you only use 4 cores perhaps you should buy a 4-core mac ? he heh just joking...
    as mentioned earlier, when things get really too hot the OS will shut the system down, and if that doesnt happen then the cpus themselves will shut down...
    the heatsinks and fans on these machines are fully capable of coping if your macine is running withing the specified ambient temp range which for the mac pro is 10° to 35° if your seeing ambient over 35 then smc fan control is probably a good idea otherwise 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.

  • [SOLVED] Question about CPU temperature

    Hi everybody,
    I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
    I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
    Here are "stable" temperatures while writing this post:
    # sensors
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +72.5°C (crit = +103.0°C)
    nouveau-pci-0100
    Adapter: PCI adapter
    temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
    Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
    And this is the output of mpstat
    # mpstat -P ALL
    Linux 3.1.6-1-ARCH (fm) 01/04/2012 _x86_64_ (4 CPU)

    10:16:50 PM 2 1.47 0.15 0.67 0.02 0.00 0.06 0.00 0.00 97.64
    10:16:50 PM 3 1.36 0.20 0.39 0.02 0.00 0.01 0.00 0.00 98.01
    The fan, of course, is full speed (very annoying)
    I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
    Any suggestion?
    Thanks.

    Just curious: what are the temperatures now? Sensors output after the "fix" would be nice.
    It's in the previous posts:
    Before (idle)

    acpitz-virtual-0

    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0: +62.0°C (high = +95.0°C, crit = +105.0°C)
    Core 2: +64.0°C (high = +95.0°C, crit = +105.0°C)
    After (after playing 8 min youtube video)
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +74.5°C (crit = +103.0°C)
    nouveau-pci-0100
    Adapter: PCI adapter
    temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
    Core 2: +75.0°C (high = +95.0°C, crit = +105.0°C)
    Fan spinning is better (less noisy) after specifying the kernel parameters.
    Thanks

  • Software for cpu temperature on bar menu?

    In Mountain Lion i used to have the CPU temperature on the bar menu.
    Is there software for Mavericks to display the motherboard temperature?

    SMCFanControl works for me. Been using it for years. found here:

  • No CPU temperature sensor on Intel based Mac mini?

    Does new Intel based Mac mini has no CPU temperature sensor like the first, PPC based, Mac mini?
    If I'm wrong what universal utility should I use to monitor the CPU temperature of my brand new Intel CoreDuo Mac mini?

    Every time a new model Mac comes out, the temperature monitoring utilities have to be updated. Obviously, the insides of the Intel Mac mini is different from the PowerPC Mac mini. The folks who write those kinds of tools can't see into the future and write a utility that will work on computers that haven't been released yet. Just give them a little while to catch up!
