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.

Late 2013 15 inch Refurb Macbook Pro CPU Temperature

Hi All,
Three days ago, I bought a refurb 15 inch Macbook Pro from apple online store. Since day 1 CPU temperature are extremely high. I have seen my Mac hitting 99 degree Celsius. This temperature was attained while I was just browsing internet on chrome and simultaneously transferring my photos from my external drive to iphoto. Also, just watching videos on youtube kicks the temperature to 75-80 degree Celsius. Idle temperature are somewhere around 45-50 degree Celsius. I don't know if this is normal and if such high temperature affects the life span of my mac. I got it checked at an apple store and their diagnostic test for cooling system found no issues. I don't know if I should return this and just buy a new one. My Mac configuration is-
Originally released October 2013
15.4-inch (diagonal) Retina display; 2880-by-1800 resolution at 220 pixels per inch 
8GB of 1600MHz DDR3L SDRAM
256GB Flash Storage
720p FaceTime HD camera
Intel Iris Pro Graphics
Any comments will be greatly appreciated. Thanks!

use safari, its much better than chrome.
Safari uses way less resources than chrome (RAM, CPU power and battery)
if the problem continues, contact apple support

MacBook Pro CPU Temperature Issue

Hi,
My MacBook Pro is becoming excessively hot, even with light usage. Currently, I have Google Chrome, Sublime Text 3, MAMP and Mail open. Google Chrome (36.0.1985.125) is the only app that is capably of heavy CPU (and MAMP, but I'm not developing any intensive scripts at this time), however I only have one or two tabs open. And neither one of them are intensive websites. Usually just PHP docs, and localhost. The average CPU activity is 1.4% System, and 2% User (it sometimes peaks to 2% System, and 5-6% User, but nothing massive).
Right now, the temperatures are averaging at 85C (and yes, that is degrees celsius). It regularly exceeds 90, and sometimes reaches just over 100C or so when just on YouTube or Facebook. I'm not sure if this is maybe related to an inaccuracy in the temperature monitor, but I use this to get the measurements. The MacBook Pro's casing does feel hot, almost painful at times when I touch the aluminium area just beyond the keyboard and below the screen for a few seconds.
The current environmental conditions for the MacBook Pro are:
- flat wooden surface (desk) to sit on
- 18C ambient room temperature
The MacBook Pro is a 15" Early 2013 with an i7 Quad-core, 8GB RAM, 1GB NVIDIA GT 650M (MacBookPro10,1) running OS X Mavericks 10.9.4.
Here's what I'd like to know:
- Is this normal?
- Would if help if I removed the cover and removed any dust (if any)?
- Do I need to take it to a repair shop?
Thanks in advance.

Make an appointment with the Genius Bar at the nearest Apple Store. Have them check your machine. Back up what you want to keep/restore before you go.
You can try another monitor solution that will tell your CPU temp, fan speed, and battery information. It is iStats, a Ruby gem that has been posted a few times in the community. The following image is from a just-powered on 2014 MBA. In the following, if you use Ruby Version Manager, the sudo is unnecessary. It may complain slightly, but does install correctly, as it works fine on my 10.9.4 machine.
$ sudo gem install iStats
$ iStats -h
$ iStats
$ sudo gem update iStats # periodically keep it current

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.

Hi Rukbat,
Thanks for your reply.
I have displayed the verbose prtdiag -v on the v890 machine.
However, I couldn't find the hard-coded operational ranges. Could you please advise?
Hi Sun-worshiper,

Macbook Pro CPU problem - idle % consistently low, please help!

Hi,
I've had my Macbook for about 8 months and never had any problems with it. Recently it started running very slow - freezing, mouse moving slow, typing response slow. I tried some solutions I found online (installing all updates, resetting NVRAM/PRAM, reindexing Spotlight, verifying disk permissions, entering purge in terminal). None of these worked. I checked Activity Monitor and the problem appears to be with the CPU, since every time the computer is running slow the Idle % is under 10%. Out of an abundance of caution, I uninstalled two Chrome plugins which were the only things I've installed in months (Adblocker and Disconnect.) I don't use any games or any other apps - pretty much all I do on my laptop is browse the internet on Chrome and use MS Word. I also have plenty of disk space, so I know that lack of storage is not causing this problem.
The only thing that has worked, at least temporarily, is shutting down, connecting to power source, and holding ctrl option shift power for 10 seconds, then turning back on (this was suggested in another thread on these forums.) The first time I did this it worked like a charm - my computer worked fine afterward, with the idle% back up to well over 90. However, it started running slow again the next day. I repeated the key process and again it seemed fine. Then again it slowed.
At this point I've tried the same solution several times and it doesn't seem to be helping anymore. Upon startup the idle% use in Activity Monitor is anywhere between 4% and 10%. The kernel_task is showing around 350% in Acitvity Monitor.
I have a very important test coming up at the end of the month and I'm studying 16 hours a day, and can't afford to be away from my computer for long. Is there ANYTHING I can do to fix this from home, or does it need to be taken into Genius under Apple care? If so, will they have to send it out and replace the hard drive, or will it be an easy in-store fix?
Any information would be appreciated! I am about sick to death of Apple products (my old first gen Macbook Air had to have its hard drive replaced twice and its screen replaced once.) If I can't find a solution I may have no choice but to up and buy a PC.

The kernel is using excessive processor cycles. Below is a partial list of causes for this condition.
Throttling
When it gets high temperature readings from the hardware, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce heat dissipation. This condition can be due to an accumulation of dust, to high ambient temperature, or to the malfunction of a cooling fan or temperature sensor. You might, or might not, see messages like the following in the Console window:
SMC::smcHandleInterruptEvent WARNING status=0x0 (0x40 not set) notif=0x0
The timestamps of those messages (if any) indicate the times, since the log was last cleared, when a processor was being throttled due to high temperature.
Note that if the problem is caused by a faulty sensor that reads too high, there may be no actual overheating.
The Apple Hardware Test, though not very reliable, is sometimes able to detect a bad fan or temperature sensor.
Using Apple Hardware Test
Encryption
Transferring large amounts of data to or from an encrypted disk image or FileVault volume may put an extra load on the kernel. If both the source and the destination are encrypted, the load may be doubled. If you transfer data from an encrypted disk image on an encrypted partition to another such image on another encrypted partition, the load may be quadrupled.
This issue probably doesn't affect late-model Macs with an Intel i-series, recent Xeon, or later processor. Those processors support hardware-accelerated encryption. You can determine what kind of processor you have by selecting About This Mac from the Apple menu in the menu bar.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or booting in safe mode (with the shift key held down at the startup chime.) Note, however, that disabling a system modification without removing it or booting in safe mode may not be as easy as you think it is.
Corrupt NVRAM or SMC data
In some cases the condition has reportedly been cleared up by resetting the NVRAM or the SMC. I can't confirm.

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.

IPad Charger temperature goes too high

I bought iPad Mini with Retina display recently. I attached a charger properly. After some time when i touched the charger I found its temperature is too high. So I removed and checked USB side of the cable, its temperature was so high that I could not hold it for more than 4-5 seconds. Is there any problem with my charger or this happens with every charger? What should I do?

Possible sign of battery failure:
1. Very hot when charging
2. Not holding charge
3. Takes a long time to charge
How old is your battery?

New Macbook Pros CPU/GPU activity vs old Macbook white

I have a white Macbook C2D with GMA950 and I getting pretty tired of hearing the fans rev up when I use CoverFlow or when I watch Youtube videos. I need some insight on the Macbook Pros (13 inch) with the 9400m. For those who had a white Macbook similar as mine and now have a new Macbook Pro, do you see a big difference in the fan activity and heat dissipation?
I also like to play Warcraft 3 once in a while from OS X, so is the Macbook Pro with 9400m way more quiet than the Macbook with the GMA950?
It's time to move on for me, can't tolerate it anymore that my computer makes so much noise in the middle of a class or in the library as I scroll my documents in CoverFlow or when I use ArcGIS with Windows XP in Parallels.
So is the Macbook Pro quiet quiet quiet?
Message was edited by: yv

There is going to be a direct relationship to CPU/GPU usage and the fan speeds. Any virtual machine you run will eat up allot of resources as it works harder. Also while playing games like Warcraft you will need to keep the settings turned down to keep the MacBook quite. Over all I would consider all the current MacBook Pro's quite. But that's just my opinion.

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?

Macbook Pro 13' or 15' for high school?

I'm 16 and I'm planing on buying a Macbook Pro, I often do video and photo editing (Adobe CS6), the main purpose of the computer would be for me carry it around school and use it as my main computer both at home and classes.
No matter what Macbook Pro I purchase, I will then update the RAM to 16GB and I will add an 240GB SSD to the Optical Drive to get quicker performance.
Now, which Macbook Pro should I get?
13' 2.5GHz or 13' 2.9GHz or 15' 2.3GHz (non-retina and all mid-2012 models)

Video requires a good GPU. The ones in the 13" MBPs are mediocre at best. Look at the 15" MBPs and pick the one within your budget. You might also consider a refurbished model which would still give much better performance than the current 13" MBPs and save you some money.
Ciao.

Apple only supports Windows on certain hardware.
http://www.apple.com/support/bootcamp/
Apple provides their framework for Windows to run on a Mac, a piece of software called a Hybrid MBR that bridges the gap between how Windows reads the drive partition table (MBR) and EFI/GUID partition table that Mac's use.
It doesn't mean Windows can't run on your Mac, a third party solution called rEFIt will also bridge the gap and allow booting of more that just Windows, Linux as well for a triple booting computer.
Your hardware has to meet the other requirements the second and third operating system needs as as being able to install drivers that will work for your hardware, especially the fans or they will run loud and fast by default.
http://refit.sourceforge.net/
This above is a advanced procedure which requires knowledge how computers and various operating systems, drive formats and so forth work.
I even admit I don't know everything myself, but I experiment on a separate piece of Mac hardware (out of warranty/AppleCare) designed for this purpose so in case something screws up I'm not taking down my only machine and can use the other to get online and find solutions.
There is a very high potential for losing your data if your using advanced/non-Apple methods to install Windows on your only Mac where Apple doesn't support it. Also one shouldn't be doing this on Mac hardware that is under AppleCare or warranty as it might be voided. Proceed at your own risk and education.
