Macbook pro 13" CPU A Diode temperature

Hi all,
I have recentlypurchased MBP13 inches (Intel Core i5 2.4 ghz, 500 G HDD, Internationalkb). I observed a difference in CPU heating behaviour compared to mypreviously used MBP 15" (2008 version).
So I did the following test:
1. CPU Temperature after 10 minutes idle (no activity except hardware monitor; user load 1-3% as measured by istat pro) :
observations:
CPU A temp diode: 42 degree C.
CPU core 1: 40 deg C
CPU core 2: 41 deg C
CPU core 3: 40 deg C
CPU core 4: 41 deg C
2. CPU temperature after 10 minutes of constant intense CPU activity ( 100% CPU load) given on both cores of the CPU
(by typing command in two terminal windows: yes > /dev/null)
CPU A temp diode : 93 degree C.
CPU core 1: 99 deg C
CPU core 2: 99 deg C
CPU core 3: 95 deg C
CPU core 4: 98 deg C
I have got two questions:
1. Is this a normal behaviour of i5 CPU heating ?
2. Why does the hardware monitor show 4 cores of CPU when in fact Intel i5 is a dual core processor ?
Thanks

Well, I talked to Apple support and tried to find out whether my observed temperature ranges vs CPU load were normal. Surprisingly, they told me that they haven't got any publicly available information on this phenomenon.
I have also inserted a plot of temperature rise vs CPU load here.
So it sounded like Apple does not want to come transparent about this issue with their customers. They only advised me to contact the nearest service center and see what is their opinion. Now in the absence of any precise and standard information about temperature ranges, I don't know what would be the basis of opinion from service center.
@pixelized - I suppose i7 overheating is increasingly discussed. But mine is i5. I guess the temperature rise vs CPU load should be different between the two processors. I have never observed temperatures like 120 C, even after 10 mins of 100% CPU load on both cores or by watching videos. Ambient room temperature was 18C in my case.
If anyone has obtained observations of temperature rise on i5, I would appreciate if you share them here.

Macbook pro 13 retina early 2013 temperature and fan issue

I bought early 2013 Retina 13' i7 two weeks ago. When I open the computer, the temperature of CPU is around 36 degree. When I just search the website, I find that the temperature is around 50 degree. And I also met the fan problems. It will goes up to 5000+ randomly.
I just want to check about the temperature. Is 50 degree normal for a macbook pro?
Thank you.

Yes, for a Retina model. Provide for adequate ventilation when in use. Elevate the rear at least 3/4 to 1". Do not use the computer on your lap, beds, or other surfaces that are not solid like a desk or table.

How i can fix this problem?
Note that: this summer I have changed my logic board to a new one and since then i never had any problem. The only this is that i'm having a warning for service battery which i think is not the issue.

Remove those kernel extensions and test again. They are not part of Mac OS X, you added them.
If you do not know how to remove them, contact the manufacturer.
If you still cannot figure it out, visit the genius bar (FREE with appointment).
They will:
make sure you have adequate Backups (which is two copies for this exercise).
erase your hard drive (which deletes everything and has no way to get it back, hence the two Backups).
Re-Install Mac OS X from original sources.
Restore your user files.
If that stops the panics, the problem was in the extensions you added.

2007 Macbook Pro having CPU problems

My macbook pro has been acting weird recently. It's been running slower, and things have been happening like...
When i watch Youtube videos sometimes, when i try to fullscreen the video, the computer takes a long time to do it sometimes and other times the computer will log out completely.
I'm a musician, and I'm trying to use Pro Tools, but even with everything closed and only one instrument open on Pro Tools, i'll get CPU overload error messages.
I have 2GB of RAM which should be enough to run Pro Tools decently.
I have 18 GB of space free on my hard drive.
I downloaded SMART Utility and it said my hard drive is fine.
Any ideas?
Thanks,
TJ

I suspect your CPU is fine however you need to increase your HD storage. Mac's need a minimum of 10-15% of the HD available at all times to run well. For example if you had a 250GB HD you would need a minimum of 25-37.5GB available. What tends to take up lots of space is media (music, video & photographs) if you off load these onto an external HD that will help.
Also 2GB of RAM is a very minimal amount. Run your computer normally then open Activity Monitor (Applications - Utilities - Activity Monitor), then click the *System Memory* tab. If your computer has around 500MB or less FREE RAM then you need a RAM upgrade too. In short this would mean your system is starved for RAM.
Finally you may have unwanted or unnecessary apps opening at login. To check and remove open System Preferences - Accounts - Highlight your account - Login Items - then select the apps you want to remove from login and click the - symbol at the bottom of the box.

MacBook Pro 15 Retina: Safe Operating Temperatures

Using iStat Menus I was able to check my Macbook pro temperature. On average I would get around 45c (113f) and when gaming I would get around 70c (158f) to 90c (194f) Is this too hot? Can anyone tell me what temperature is too hot?

also, does the machine get enough ventilation w the lid shut? what if i'm maxing out processor / ram / video and bootcamp?

MacBook Pro System CPU Spikes When Unplugged

Upgraded to Mavericks a few days ago and,whenever I unplug my MacBook Pro 13" (Early 2011 - 2.3GHz Intel Core i5 - 16GB RAM 1333MHz) and run just on the battery, my system CPU usage goes through the roof which results in my Mac running/responding very slowly and buggy.
However, looking at the iStat widget on my dashboard, it's reporting that my CPU isn't running hot nor does my MacBook Pro feel hot at all. It's also showing that I still have 10GB of RAM free.
As expected, once my magsafe is reattached to my laptop and plugged back in, the system CPU returns to a normal level. In Activity Monitor, it shows kernel_task as being the culprit.
I queried the log as suggested by Linc and TextEdit had something for me:
Dec 10 15:51:31 My-MBP kernel[0] <Debug>: Process Setup Assistant [307] disabling system-wide I/O Throttling
Anyone have any idea what this could be? Seems like it should be a simple software config but I just don't know.
Additionally, I also ran EtreCheck. These are the results when it's running unplugged:

Does anyone have any ideas on why this is happening or are experiencing anything similar? I can't for the life of me figure out if it's a Mavericks issue or if it's a hardware issue. Any advice would be much appreciated! Thanks!

You're not going to believe this but I just now found a working solution!!!
Thanks to the talents of a man named, Rhys Oxenhams, and his flawless tutorial, eveything's running normally now!
BEFORE READING ON...make sure you backup all of you data! I take no responsibility for anything bad that happens to your machine. I'm providing this information because it worked for me. There's no guarantee it will work on your system. TAKE ALL NECESSARY PRECAUTIONS BEFORE READING ON and BACKUP YOUR DATA IMMEDIATELY.
Here's what you need to do:
1. In the Finder menu bar, click on Go and select Computer. 2. In the window that comes up, double-click your computer's HD. For me, it's Macintosh HD. 3. From there, click on System > Library > Extensions. 4. Now look for a file called IOPlatformPluginFamily.kext. 5. Right-click on IOPlatformPluginFamily.kext and choose Show Package Contents. 6. In that new window that comes up, click on Contents > Plugins and locate ACPI_SMC_PlatformPlugin.kext. 7. Just like in step 5, right-click on ACPI_SMC_PlatformPlugin.kext and choose Show Package Contents. 8. Just like in step 6, in that new window that comes up, click on Contents > Resources and locate your Model Identifer.
     • In case you don't know what your Model ID is, click on the  in the top left of the screen and choose About This Mac     • In the window that comes up, click on More Info...     • In the next window that comes up, click on System Report     • In the very first screen, towards the top, locate the entry Model Identifier          - Write this info down on a piece of paper. You will need it. In my case, I wrote down MacBookPro8,1 9. Back in the Resources folder, locate the .plist file that has your model identifier. In my case, it was MacBookPro8,1.plist 10. You're not going to delete that file but instead move it to a differnt folder inside your home folder--doesn't matter which folder, just put it somewhere inside your home folder. 11. Restart your machine and you are good to go!
Let me know how it turns out for you. REMINDER: Backup your data before doing this!

Macbook Pro Retina CPU Overheating when doing simple tasks?

I've had my Macbook Pro w/ Retina since July 2012 and for about a month now (starting in November) the CPU Die - Digital has been getting EXTREMELY overheated. It has gotten up to 210 degrees F which is way past the damaging level of CPU but the real kicker is that it happens when I have a few tabs open in safari and a couple other minor programs open (Mail, Finder, App Store, Skype, iTunes). It's not like I'm running Skyrim, LoL, and Starcraft while running background tasks in Fincal Cut X and Motion V?? I mean I have 16GB of ram and only 5 or 6 of it is in use so it's not a problem with multitasking and processing power also shouldn't pose much of a threat for a few tabs in a browser and some low usage programs. I use iStat Menu's and I took a screenshot just now of it in the 180's when it was recently in the 190's. I also checked the disk utility and I can't see anything in the CPU usage that would make it work that hard.
My questions are am I doing something wrong? Is there something I'm missing? Is my laptop defective and in need of refurbishing using Apple Care? Is this happening to anyone else?
Thank you in advance.

Turn off Skype and see if that has any affect. Skype is is a notorious heat generator.
Did you check Activity Monitor?
Ciao.

Macbook pro 13" cpu 320%

i dont know what happened to my mac but now everytime i turn it on the fan starts to run too fast and the cpu goes over 320%, first i was able to work with it but everything was super slow, now i cant do anything i just can go on the recover menu and try to repair the hdd but i cant , i dont want to lose my data
help please

Well, I talked to Apple support and tried to find out whether my observed temperature ranges vs CPU load were normal. Surprisingly, they told me that they haven't got any publicly available information on this phenomenon.
I have also inserted a plot of temperature rise vs CPU load here.
So it sounded like Apple does not want to come transparent about this issue with their customers. They only advised me to contact the nearest service center and see what is their opinion. Now in the absence of any precise and standard information about temperature ranges, I don't know what would be the basis of opinion from service center.
@pixelized - I suppose i7 overheating is increasingly discussed. But mine is i5. I guess the temperature rise vs CPU load should be different between the two processors. I have never observed temperatures like 120 C, even after 10 mins of 100% CPU load on both cores or by watching videos. Ambient room temperature was 18C in my case.
If anyone has obtained observations of temperature rise on i5, I would appreciate if you share them here.

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 Early 2015 MacBook Pro fans are at 0 RPM and my cpu temperature never fluctuates

Hello all I have had a Mid 2009 macbook pro for 5 years now and just got my Early 2015 MacBook Pro. On my old macbook i used iStat and SMC fan controller religiously and everything worked great.
Now with my new Early 2015 MacBook Pro, My CPU sensor doesn't even show up in iStat, and in my top toolbar, SMC controller shows my CPU temp never moves, and my fans are at 0 RPM. I cannot hear any fans moving at all when in a completely silent room, and my ear is to the computer.
I downloaded a game to stress the CPU to see if it'd change, and it doesn't all the way up to the fans just coming on at 6000RPM and the CPU is very high like 80-90C
I have already reset my PRAM and SMC and was wondering if anyone here has been monitoring their temps and have seen the same thing?
Thanks

I also have an Early 2015 rMBP w/ i5-5287U cpu. I am using Temperature Gauge from the Mac App Store and getting similar if not slightly worse results. I'm usually Idling somewhere between 45 and 60 C with almost no activity. When I run games, forget about it (see below), temps up to 103 Celsius. I also experience almost no fans until at least 70 C, and then during gaming the heat is not coming down.
Given that the cpu is supposed to shut itself down at around 105 C, I'm thinking that the programs are not decoding the temperature sensors correctly. This is my first Mac so it's hard for me to compare performance. I expected better heat regulation. I was trying to avoid programs outside of the mac store for this type of thing, but I'm considering OGELTHORPE's suggestion for istat menus, as they do claim to support early 2015 MacBooks. Have you tried this program yet?

Operating Temperature Limit for MacBook Pro

The specifications, for MacBook Pro, mention that the operating temperature is 10 to 35 Deg C. Does it mean that MacBook Pro will not function above 35 Deg C? Is it recommended to operate MacBook Pro always in an air-conditioned environment? As I plan to buy for the 1st time, I seek an answer.

You will find that if you use applications that are CPU intensive the internal temperature can go over 100 C. This actually is within the safe operating parameters of the MBP. Should the temperatures become excessive, there are heat sensors that will activate a shutdown so that no damage will occur.
You might download from the Internet a utility called iStat pro that will show you the internal temperatures of your MBP and the fan speeds. You can then correlate this information with Activity Monitor data and determine if the temperatures are normal for the given circumstances.
Ciao.

Please Post Macbook Pro Temperatures here.

All Macbook Pro owners, please post your macbook pro temperatures here. This would allow us owners to clearly identify what an "average" temperature is, and what would be considered over-excessive heating of our Macbook Pros.
Below are two useful applications (one is a widget) to find out the temperatures of your computers.
http://www.bresink.de/osx/TemperatureMonitorWE.html (a widget)
http://www.versiontracker.com/dyn/moreinfo/macosx/19994 (a comprehensive application)
when posting your temperature, please do post some specs of your macbook pro.
This is greatly appreciated. thank you (:
for starters, my macbook pro is a 1.83 ghz intel duo core, 512 mb ram, 128mb graphics card. it supposedly comes from the batch produced on the day of 31st March, 2006. I think it is a revision D.
So far, doing normal tasks like web browsing, etc, my macbook pro has been at a temperature of 42 degrees celsius.

I have a MBP 1,83 and I did the "yes-command" with two Termial Windows, that means my two processors are running at 100%. The
Fans are running and holding a constant temperature of 75°C.
In "normal-work-mode" the temperature is rising up to 62°C, but this takes about an hour. At the moment I have a processor usage of about 6% and a temperature of 48°C.
When I am at about about 62°, I get the "mooing". I am very sure that this is caused by a fan on the left side, because I get the same noise, when I do the "yes-command" but then the fan is accelerating. When I get the mooing it is going up and after a little while down.

In my shared area on network it's displaying that I shared with a fellow macbook pro

However I haven't shared with any other macbook pro user, to the best of my knowledge, so I am wondering how this has appeared, or am I just being completely stupid and is it just displaying my macbook pro?

This are the temperatures i get when i have my poweradapter connected.
But i've noticed that the temperature drops a lot when i disconnect it all the cpu core temperatures drop with 20-25°C

MacBook Pro really hot while idling after 10.6.6

Not sure what caused it, but definitely the update to 10.6.6.
My MacBook Pro's CPU temp is oscillating the whole time. often a few degrees C every two seconds,
it also get seriously hot.
Before the update it would idle at 50 °C, now it idles at 65°C.
Note that at this temperatures the fans are running at minimal speed (2000 rpm),
so no changes here.
Anyone else?

Same thing here. I update my late 15" 2008 unibody Macbook Pro from 10.6.4 to 10.6.6. CPU temperature used to be around 42C (using internal graphics). Now it's at 68C with no applications running, and CPU at single-digit % load. Actually, I just saw it hit 83C after opening a disk image.
I upgraded using the combo installer. I will probably downgrade back to 10.6.4 until I find a resolution to this.
(Wow-- running any app and I'm in the high 70C range.)

Mid-2009 Macbook Pro will not turn on

Hi Folks,
so my mid-2009 15in Macbook Pro will not turn on. I updated the OS to Mavericks in December 2013. I'm from California, but I recently moved to the Guam/Marianas area where it is more humid and generally around 87 degrees F all day. For the past month my computer has worked fine, albeit I did notice the fan was running a little more than usual. I usually would just put it into sleep mode when I would finish using it (apparently a bad idea based off of reading other posts concerning humidity and, more importantly, heat). One day I finished using it, closed it and the next day went to open it; I could hear the fans start to work, but then it stopped. It hasn't turned on since. You press the power button and nothing happens. I tried all the troubleshooting stuff.
So, my question is this: what do you think is the problem? Moreover, how much do you think it could cost to repair it? My experience with computers suggests to me that it's probably a dead motherboard. I'm wondering if it's worth trying to salvage this thing or if it would be prohibitively expensive. There are no Apple stores in the area to take it in to get advice unfortunately.
Now, I just want to vent a little frustration. I have many apple products, and I've even switched my mother over to an apple computer, but now that I need some very basic support, apple doesn't provide a contact e-mail or a free chat? I think charging someone $19 for 'one time assistance' is ludicrous. I bet if I brought this into an apple store I could at least get some advice, and thus get some idea how I want to proceed with repairs or not. I suppose I'm also rather frustrated that my macbook, which I have been most happy with all these years, breaks because I go somewhere a little more humid and generally warmer? It would appear that the hardware failure is connected to the climate. This makes me skeptical about purchasing another mac if it can't handle a little humidity. (I have not spilled liquids on it, nor have used this computer while transitioning from an air-conditioned/humid location which could potentially cause condensation). I do not think I'm being unreasonable (yes I do think a $2500 computer should not fail after less than 5 years), but if you think I am unreasonable, please enlighten me.
Thanks for any help. I really appreciate it.
Ken

Ken,
the “Important Handling Information” in the little white manual that came in the box with your MacBook Pro states that its operating temperature range is from 50 °F to 95 °F (10 °C to 35 °C), and that its operating range of relative humidity is 5% to 90% (non-condensing). If your corner of the Pacific is outside of these ranges, the manual states that “Failure to follow these handling instructions could result in damage to your MacBook Pro”.
I have no idea what problem your MacBook Pro has; since you’ve tried all of the troubleshooting stuff, you’ll need to somehow get your MacBook Pro to a qualified service facility to diagnose the problem. If the logic board does need to be replaced, it would probably cost hundreds of dollars for a replacement, and you might find that purchasing a replacement used MacBook Pro of the same model to be price-competitive with just replacing your MacBook Pro’s logic board.
If you find Apple’s out-of-warranty policies unacceptable, then your only alternative to venting would be to purchase your next computer from a different company which has out-of-warranty policies more to your taste.
