Can high cpu temperature melt processor?

Hallo, mayby stupid question, but i was just wondering, if high temperature inside my macbook air (2012 i5) can melt my processor or something like that...
I am talking about 85 C continuosly1 or max 2 hours per day at cpu (oc course not every day) :/ i dont want to demage my mac...
Thx for any answers.

High enough temperatures can melt anything, but your mackbook air is designed to operate continuously, with fans to manage CPU temp. As long as you are in an environment where the air temperature is within standard (10 to 35C), your macbook is fine.

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!

Combo: High CPU temperature

Hi,
My PC CPU temperature is 43C when idle. But it rises up to 60C when under load.
The system temperature ranges from 35 to 38 depending on system load.
I have double checked CPU fan, it is perfectly attached.
CPU clock is 3.0 GB 1MB, 512 DDR1 @ 400 MHz
I am running the system on the default clocks (No overclocking).
3 Fans for system cooling.
Is this normal temperature?
Thanks,

Very normal, Almost to cold for a Prescott! I would like to see these temps at my system.....

High CPU temperature on Tecra M5

I dont know if it's normal, but my CPU has a normal temperature of 77C, and when the CPU increases to 50%, the temperature increases to 100C.
Is this normal?
My fan is always making to much noise...
I'm using Vista and a trial tool for monitoring temperature - hardware temperature monitor 4.3

Hi,
this hardware monitoring tools are not giving the real temp out. I tried Hardware doctor and it says that my Qosmio is running about 120 (!!) so I dont think its supposed to be the
real temperature of my CPU!
If your FAN is running constantly, maybe your fan and cooling system is clobbed with dust. Maybe cleaning the whole thing would be useful. On the other side, try to adjust the setting in the "toshiba power saver" and try to find settings which fit for you (performance/silence) because you have a powerful system and then its normal that your fan is running high.
He had to cool a CPU, a VGA and a little bit of heat out of the case.

High CPU temperature

Please is normal that a MBP 15'' 2.8GHz while encoding video of normal quality reaches 95 DEgrees Celsius and use of 125% of CPU, fans were going at 6200 rpm

SOLVED
but anyway I got a little help by searching this forum to find out how "to find" out why my mac is overheating.
The reason was the adobe distiller, the invisibly was running all the time. I'm using a lot adobe pdf printing in file - and there was a printing job still hanging on, and with some problems. Just in case anybody will encouter the same problem:
check the print&faxes->printing->print queue...
My temp went no back to 50% and activity to 5% and the fans are off so I can enjoy it again!

High CPU temperatures with Yosemite

Hi,
Today I made a clean install of Yosemite on my Macbook Pro. I saw a big difference of the cpu and other components temperature than Mavericks:
(the weather is not changed from yesterday)
Yosemite:
- Safari with only an open tab
cpu: 58°-67°
Mavericks:
- Safari with three open tabs (Facebook, Gmail, Youtube)
- Illustrator cs3 with an open file (big size an some vectors)
- iTunes
48°-52°
Also the battery lost 50 minutes of autonomy than the same situation with Mavericks
Yosemite uses too much cpu (gpu) resources or is a poorly optimised s.o.
Probably Istat Pro is still not too compatible wit the new os x....I hope in some fix or update that improves the situation (for Yosemite...)
Someone has encountered the same problem?
MacBook Pro (17-inch, Late 2011), 2,4 GHz Intel Core i7, 8 GB 1333 MHz DDR3

Open Activity Monitor and see what's running in the background under All Processes.
Whatever is using most of your CPU's resources is not needed, click on quit process and see if that helps keep your CPU run cooler.
Also, check your login items and see what's loading when you start your MB Pro. Uncheck those items if not needed and restart your computer.
I have a Late 2011 MB Pro that has an idle temp of 47 - 50 C.
Another possible solution, if you're techically competent, open the back of your MB Pro and blow off gently the inside of your MB Pro to get rid of any dust or particles inside your notebook.

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

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.

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.
However, It appears to me that the CPU temperatures is higher than the temperature range specified in the technical specification. The server is a standalone node that does not connect to the network or process anything.
Is it a problem? Thank you.

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.

I use the imac mainly for editing Video which when doing so it has reached temperatures of near to 60° C which causes the program to become unstable and needs to be cooled down to operate correctly.
An Apple technician (by phone) advised me to download an smcfancontrol. This allows each individual fan to increase speed and also advises the current temperature at °C. The smcfancontrol has been downloaded but this has not resolved the problem. By increasing the speed of the fan more heat is generated and creates additional noise.
I have since taken the iMac to an Apple Store for examination as suggested by APPLECARE when the fans were found to be working correctly. An Apple Store technician carried out a test, but not whilst working under the pressure of FINAL CUT PRO when the iMac generates a high temperature.
The Temperature Specification for this model is
Operating Temperature 20 °c to 35°C

Clearly the temperature my iMac is operating at is excessive and could cause the computer to break down prematurely. Has anyone experienced this problem.

When was the last time you cleaned/vacuumed out all of your iMac's vents, slots and ports.
You need to do this with the iMac powered down, disconnected from power and everything disconnected.
Lay your iMac, screen down, on a soft surface, like a heavy towel. Use a small electronics vac, or portable or full size vac with hose and a crevice tool attachment and carefully and slowly vacuum every vent, slot and port on your iMac.
Then reconnect everything up, power up and download and install iStat Pro. Start working, then report the temps of your iMac after this has been done.
When using SMCFan Control, it is important not to run the fans at too high an RPM. This doesn't generate heat on its own, but will suck in more dust, lint and dirt into your iMac, and that will be the cause of additonal increases in heat.
I run my fans in the range of 1400-1600 RPMs. You can go as high as 1800 RPMs but it is important to keep the RPM range below either 1800 or below 2000 RPMs.
I, also, run a very small desktop fan pointed toward the upper back of my iMac to keep temps down even further.

CPU temperature seems rather high

I have a Lenovo Thinkpad R61, and my temperature under normal load seems to stagnate around 50 degrees Celcius, which seems kind of high. When put under heavy load (compiling a kernel) it steadily rose to around 66 degrees celcius before I stopped the operation. While under heavy load, /proc/acpi/ibm/fan reported 3202, and under normal load now it reports 3125. Is it just me, or this CPU temperature kind of high? What can I do about it?
PS: Because it's a thinkpad, I can't use lm_sensors. thinkpad_acpi module takes care of such things.

Hah, IME laptops = heaters.
Even my dinosaur P2 celeron lappy gets to 70C CPU under load BEFORE the BIOS turns on the fan.
I think the idea is to hold off running the cooling as long as possible so cpuidle/speedstep can allow the chip to cool before using battery to run the fan.
As for the AC adaptor heating up, this smacks of poor design, the PSU should be able to maintain full load + battery charging for at least as long as a full charge from empty takes. Anything else is cutting corners based on 'yeah but how often will THAT happen'.
If your ACPI setup is not doing what it should, power consumption + heat output will be excesive under no/low load but full load power is full load power, as there is nothing to turn off.
My attitude would be, set up acpi and speedstep then ignore the temps. If it cooks under load then the hardware cooling solution is rubbish.
Seriously though, your temps sound quite normal. Look up the specs for your CPU on processorfinder.intel.com (or the AMD equivalent) you will probably be surprised at how high the max temperatures are. As for the AC adaptor - Don't run full speed while the battery is charging? The damn thing should be designed to handle it.
Do try and keep the HDD cool if you can - it is spinning down when not used right? Modern HDDs generate a fair bit of heat themselves when running and there ain't much airflow around the disc in most laptops.
EDIT: your HDD temps look sweet.
Have you played with laptop_mode?

Is 95C CPU temperature too high?

I have Intel Core 2 Duo iMac. When I use QuickTime or any other video converting software to convert video for my iPhone CPU temperature hits 95C mark. Is it too high? Should I do something about it. If yes what should I do? It is the only situation when CPU temp is so high usually it is not higher then 70C when loaded.

Hi,
thats normal that the CPU of an mobile system gets hotter, I mean your much more near the CPU then by an desktop. Thats normal that you could think the CPU gets too hot.
I have an Satellite X200 (Gamer machine) and the thing gets really hot, but thats normal since a powerful CPU is in there.
If I were you I wouldnt make any doubt about it and if youre unsure just ask some of your friends which owns a notebook. Usually they would say "yes, mine gets hot, too.."
The 100 degree means that the CPU can become such hot till it reaches 100 degree and then the machine shuts down to prevent to some damage on the CPU.
So in this case the 70 degree are okay. You (can by the way) prevent overheating when you clean your machine regurarely simply by blasting some compressed air gently through the ventilation holes of the CPU cooling system. If not then the cooling modules will be clogged from dust and start to overheat...

How can we analyze high CPU usage on JRockit ??

Is it possible to analyze high cpu usage through JRA recording ??
OS : Red Hat Linux
Or is there any other way we can analyze it .
Please let me know its urgent ....
Thanks in Advance

Hi!
It is indeed possible to use JRA to find out where the time is spent! The hot methods table in JRA shows where the JVM is spending the most time executing.
Kind regards,
Marcus
