MacBook CPU Temperature

For the last several months my MacBook fan start to run as soon as I do anything processor intensive - including running a screensaver. As soon as I do something other than read mail or write in BBedit the fan revs up to 6000+ rpm. Looking at iState menu right now: Handbrake is the highest load, running using about 50% of the CPU. CPU temp is 99C, heatsink A 57C, heatsink B 56C, and the Enclosure base is 27C. The fan, as usual is running over 6000 rpm.
Is this normal? Could it be that thermal paste problem? Internet research has been more confusing than helpful.
Applecare is long expired - This is an early 2008 model.
Thanks

yep. and i bet, your fan isn't even spinning at its 6200 rpm maxmimum to accomplish this.
ok. as far as i understand it, different mabook series allow for different cpu temperatures and accordingly have a different fan behavior depending on which cpu is installed and which buliding materials are used in the book itself. so we can't directly compare your 2007 model to his 2008 or my 2009 model. but one thing pertains to all machines: if the fan spins at it's absolute maximum speed for a longer time period and temperatures do not drop noticeable, and if the fan never showed this behavior before, there's probably something wrong.
either the ventilation is blocked for some reason or the thermal paste is disintegrating. i would have checked it at the store. also, there is this wide gap between cpu temperature and heatsink temperature. for all i know, it's normally a difference up tof 15-20°, but not arround 40°.

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.

Macbook Pro Retina Late 2013 CPU temperature issues while gaming (99 celsius) Is this normal ?

Hello everyone, this is my first time here. I recently purchased a macbook pro retina late 2013 notebook just over a month ago. It seems to be working just fine. I've installed bootcamp and installed windows 7. I use Speccy for my temperature monitor. I've played DayZ Standalone as well as L4D2. I noticed while playing both games on their lowest settings the CPU temperature consistently stays in the 90 degree celsius range often reaching 99 degrees celsius. I am fairly tech saavy and have a decent knowledge of computers.I bought the ThermaPak Heatshift pad in hopes of cooling it down but to no avail as it only does a great job at cooling everything else. This is my first laptop so I treat it like my baby ! haha I was wondering if these temp readings are normal because I know that even reaching 70 celsius can be somewhat damaging. Thank you for your assistance.
EDIT:
I've attached a screenshot of the temperature for proof

So I just got back from the apple store and wow, what rude service. The guy basically shrugged when I told him "Well, I guess Im stuck with it huh?" after he told me there was no way I could get a refund. He performed a test and told me everything was fine and told me in a very arrogant manner that the test isn't showing the results I told them about as if I was lying....***? He said they can send it away for a few weeks but I don't have any other computer and I just bought this one for school so I can't afford to have it gone for that long. He told me "doesn't your school have a computer lab"? Seriously, how can someone at Apple be this rude? I told him they do but its closed at 7 and I dont live on campus. How could a computer lab replace a personal computer? He basically kept shrugging rudely anytime I tried to find a solution. He didn't even reply with a single word. When I told him I called the call center and they told me that yes it is much too hot and to take it to the store after doing a fix he just chuckled and rolled his eyes. Really? I spent 1500 dollars on this computer to not even be able to do basic things on it without it overheating and the service is this bad? Well, looks like I won't ever be buying an apple product again even though before this experience I was a huge fan of all their products. I know one customer doesnt make a difference to them but come on...looks like I'm stuck with it and apple couldnt give one care. If having your hands uncomfortably hot after a small amount of time is acceptable then it looks like I'll never be buying another laptop from them. Its a shame I really liked it at first.

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

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?

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.

Macbook Pro temperature after installing Mountain Lion

Hi guys,
I wonder if any of you could give me a little help.
I installed ML about one week ago and i've been noticing that my macbook pro (from mid 2009, 13inch) has been increasing. With itunes, chrome a minor download program called igetter CPU temperatures are around 65/75 and if I open anything new, normally a new page on the browser for instance, it easily reaches 80/85. What puzzles me is that CPU usage is still really low...
I have repaired some permissions with Onyx and clean up some programs i've installed so far but nothing changed this issue with high temperatures.
I really don't know what else to do...
Thanks in advance.

I have same problem with my 19 MBP March 2012
64C always, FUN works always
After starting iMovie iPhoto for example it heats up to 97C
Terrible!!!
I dont have time to roll back to Lion, but I think I need to do this
TC if SMC and PRAM helps write here please
Anyone can help more?

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.

Max CPU temperature

Hi, I have a MacBook Air in 2010. What is the maximum temperature can reach the processor so as not to cause damage? I ask because sometimes I use HandBrake and the CPU temperature sometimes reaches 95 degrees Celsius.

100 degrees Celsius is the max. The MBair will throttle back processors and spin up the fans to compensate. If it can't cool the machine to remain in operating limits then a thermal check will occur and it will power off.

Macbook CPU full load, 99 degrees celsius

On my late 2008 13" Macbook 2.4ghz when I run 2 instances of "yes > /dev/null" for 10 minutes to stress the CPU, the CPU temperature is at 99 degrees celsius even with the fans going at the maximum 6200 rpms and while using a cheap cooling pad. I took the computer to an Apple store "genius" and he thought this was normal. Is anyone else seeing temperatures like this using this stress test method? I looked at the website http://www.intelmactemp.com/ and highest full load temperature I see for this computer is 84 degrees celsius. I have noticed problems running intensive 3d games where the system slows down from high temperatures and more so under Windows XP.
This computer is 4 months out of warranty but until recently I never ran intensive programs and so never noticed the problem. What can I do about this, I feel Apple should be responsible for this.

Hi MindBrain,
Saw your post last night but didn't have immediate access to 13" MacBook (Aluminum). So I've got a 2.4GHz unit with 4GB of RAM and ran two instances of the same command in Terminal.
All information is reported via iStat Pro:
CPU Temp before test - 76 (fans at 1998 RPM)
CPU Temp @ 5 minutes into test - 96 (fans at 2001 RPM)
CPU Temp @ 10 minutes into test - 97 (fans at 3100 RPM)
CPU Temp @ 15 minutes into test - 103 (fans at 5800 RPM)
CPU Temp @ 20 minutes into test - 106 (fans at 6200 RPM)
CPU Temp @ 25 minutes into test - 108 (fans at 6200 RPM)
For thoroughness, I also opted to run the test on a brand new 13" MacBook Pro, a 2 year old white MacBook 2.2GHz and another MacBook Aluminum. It's convenience I have when surrounded by 5600+ Macs across campus. All of the other machines also reported similar numbers, breaking the 100 degree threshold between 12-13 minutes into the test.
While I do not wish to discredit that URL, in all honesty I've probably had three times the number of entries on that website (611 as of this post) come across my desk in the past year for various reasons. So I really can't see that as being a valid resource to support an argument.
Not to mention it was your decision to not purchase AppleCare on your computer within the one year window, it was also your decision to not properly ensure adequate function of your machine prior to conclusion of the one year limited warranty. There was no responsibility on behalf of Apple to obligate you to stress test the machine 4 months after the one year warranty expired.
Lastly, is the sluggishness only in Windows XP or is it occurring on the Mac side as well?

MBPr CPU temperature 100c+ at low usage!

I'm new to Mac having been a Windows user for many years and love my new Macbook Pro Retina. I switched because I am now doing a lot of Photoshop work and HD video editing and the Macbook and OS X just seems to do everything I want but better. I was a bit unsure because of the price but managed to get a good deal on an ex-display (that never actually went out on display) 2.6ghz 8gb 512gb model so took the plunge.
I have read a lot about concerns over CPU temperatures with the retina models so deided to install iStat and see what mine was doing. Having read the results other people have been getting I am a little concerned about mine. I have been backing up a lot of files from an old USB drive to a new network drive via the Macbook (using Thunderbolt/Ethernet adapter) and my CPU core temperatures have been spiking to around 100'c while the files are transferring (currently at 103). I have been doing a little web browsing at the same time but CPU usage has barely gone above 10%. The fans kick don't seem to be going much above 4000rpm and the case is just warm, not hot. Considering the low CPU load I am puzzled as to my the temperatures should be so high. Having read comments about iStat being outdated I also installed the latest version of Temperature Monitor but that show the same results. All software including OS is up to date.
Any feedback would be greatly appreciated!

Just switched the Macbook on again and only have Safari open. The system is sitting at a steady 75'c with CPU uage at 8% and both fans running at around 2200rpm. This is really strange as the Macbook doesn't seem particularly warm anywhere on the case either.
Is it possible that both temperature monitor apps are giving false readings? Is there any way that these can be 'reset'?

Cpu temperature without fancontrol

Hi, after i installed mavericks, awesome! i clean up my mac and i removed fancontrol.
now, whit fancontrol, the cpu temperature in idle is 40-45 c°, fan rpm abot 3000-3500 and when i open a game, the temperature reach about 80 or more but immediately the fan rpm change to 5500-6000 and it's ok.
whitout fan control, the cpu temperature in idle is 50 c°, fan control always 2000 rpm and the same try with a game, the fan rpm change to 6000 very slowly after the cpu temperature reach 90-95 c°...
i had that problem since i bought this air then i ever kept fan control!
of course now the battery reach 4 and half hours or 5 than before with fancontrol (2 and half hours), but are you sure it's not dangerous?!

You call it a problem. I don't see a problem.
Not only are you are not exceeding the safe operating temp, but it is entirely expected to hover in that area for many types of games.
While not a "gaming rig", the Air is quite competent for many gaming purposes. Just don't expect it to leisurely lope like a Macbook Pro. The CPU will indeed be pushed rather hard in these circumstances. Sure, you may be able to push the fan harder, and acheive a slightly lower operating temp, but I don't see the point.
The fan itself, being a moving part that you can't do much to maintain, is something I'd rather preserve UNLESS the temps were so high, and my need so strong, that I just had to push things beyond the stock cooling system's effectiveness.
Your worries, pertaiing to your post here, are rather unfounded.

Normal CPU temperature range

I'm curious if anyone knows what the normal CPU temperature range is for a Macbook? I just installed istatpro so I can now check it. The current CPU temp is 140F and the fan is at 1,500 rpm. At what temp does the fan kick into a higher speed?
Thanks for the help.

The normal range is about 30º-85ºC depending upon CPU and GPU loads. Maximum is 125ºC at which point thermal shutdown occurs (your machine will shut down.) The fans change speed with temperature according to a hard-coded table (not firmware encoded.) The older Core Duo laptops such as yours have a lower fan idle speed than the newer models. Although not supported by Apple you can install third-party software that can be used to increase the fan's idle speed - Fan Control or SMC FanControl. Use at your own risk. The subsequent laptop models now use an idle speed around 2,000 RPM which tends to keep the machines a little cooler. However, this has no effect on when the fan will ramp up to higher revs. The software only raises the idle speed.

When playing CoD 4, CPU Temperature 85. Is it normal ?

Hi friends, my macbook pro 13" mid 2010's temperature on normal using 41
but when Call of Duty 4 playing, CPU temperature is 75-85
Is it normal ? Can it be a problem ? Please help friends,
have a nice day !!

Not the best gaming machine, but if your fans kick in and keep the temperature stable, you're ok in the short term. Over time, heat will degrade the battery prematurely and lessen the life of other components.
Keep it well ventilated.

CPU temperature increases considerably as well as fan speed after upgrading to 10.7.4

I'm running an 8,1 MacBook Pro and just upgraded to 10.7.4. While idle, my CPU temperature now stands at around 180 degrees Fahrenheit and my fan runs at 4000+ rpm. Is anyone else having these issues? How should I try to fix?

Start here:
Using Activity Monitor to read System Memory and determine how much RAM is being used
How much green? under 1/6 pie?
How many pageouts?
When you are comfortable with that information switch to this view:
Runaway applications can shorten battery runtime
What is the biggest CPU User, and how much is it using?
