MBP internal cooling: Dangerous temperatures.

I've run into a very strange situation with my MBP.
I do play video games on my MBP, and it handles them quite nicely.
But.
I've recently bough a Zalman 3000 to help keep it cool, to protect it.
But the external temperatures stay where they usually are when they idle.
The CPU/Graphics card temperatures however, reach upward of 85C+ and skyrocket.
Meanwhile, the fan idles at 2000 rpm (keep in mind my CPU/Graphics card is frying).
I can't imagine why the internal fans wouldn't kick-in. My cooling pad ***** air AWAY from the laptop, and does so quite nicely.
Please help me.

MBP internal drive failure causes external drive probs. Weird...

I've been booting off an external drive for some months now. I figured it would save wear on the internal drive, and when my boot drive eventually failed (the external one) it would be quicker and a lot cheaper to swap that out with another external one than to have to change the internal drive. I use FW800 and not seen any performance hit.
Yesterday (with the whole system booted from the external drive) it started going really buggy, everything was painfully slow - like, virtually at a standstill, and with a very slow wi-fi internet connection.
I tried rebooting. It would only boot from the external drive, and only if I held down the option key and selected a boot from the options that appear. Otherwise just the apple symbol and an endless twirly. It wouldn't boot from the internal drive +at all.+
Eventually I booted from the SL disk and ran disk utilities. To my surprise the internal drive was corrupted in some way and couldn't be repaired. I wiped the drive and restored it using Time Machine (stored on yet another drive). Everything then worked fine, except for the slow wi-fi.
So, +why should a corrupted internal drive stop the MBP booting from an external drive?+ This is worrying for me if the machine ever goes down at work and I have to rely on booting from another drive, which then might not boot properly and is buggy.
To complicate matters (or does it offer a clue?) this morning I booted from the usual external drive. It worked ok, but wi-fi was still slow. Another Mac here was showing the same internet slowness, so I figured it was maybe the ISP.
Then the MBP itself started going slow n buggy again. A check on the internal drive showed no return of yesterday's probs. On a hunch I unplugged the router from the mains and plugged it in again. The wi-fi then worked properly as did everything else.
+Why would a buggy router affect my MBP? Could it have corrupted the internal drive?? Why should any of that affect the machine's ability to boot from an external drive..?+
Thoughts anyone?

it's solved, thanks to clinton:

I7 15" MBP loads cooler than my previous Core2Duo 15"

I was getting a bit annoyed my Core2Duo 15" MBP was running so hot. Sitting in bed my legs were starting to burn. After reading all the stories about the i7 chips running at 100oC+ I was about to expect the same, but surprisingly it seems to run cooler than the previous MBP
The area above F2,3,4 was pretty much hot all the time before. Now it's barely warm with the i7
I'll start playing some games soon and see how warm it gets then

My 2.4GHz Corei5 runs 8-10C cooler than my old 2.53GHz Core2Duo. However, the ranges for the Corei5 idle are 50-55C in clamshell mode and the C2D were 60-65C.
100C is hot for an aluminum 2008+ MBP even under load, I've never got one over 87C running 2 cores 100% with a scientific program written in C on either architecture. I would recommend using iStatPro for your dashboard to monitor the fans and temperatures of the various components. If your fans didn't kick in when running CPU intensive programs, you might have had an issue with your C2D 15" MBP.
I have seen a 2007 2.2GHz C2D white Macbook at 97C running the same C code with both cores at 100% CPU. I would think that this is directly related to the plastic MacBooks not being as thermally efficient due to their construction. Aluminum is a decent heatsink; plastic is not.

Mbp normal variance in temperatures?

My Macbook pro (core duo 1.86ghz) has always been extremely hot to touch, but I never thought twice about it. About a week ago I installed coreduotemp to monitor the temperatures and noticed that it reaches 96c when the processor is under load (no 3d graphics, laptop on a wooden table in a cool air conditioned room). Some parts of the notebooks cover get so hot that when a workmate accidentally touched it he screamed.
Since we have a lot of Macbook pro's where I work, I took an identical (apart from a 2.16ghz processor) model and did a profile transfer to it. When both notebooks where under load the difference in temperature was was over over 30c (64c vs 96c)! There is also a huge difference in how hot the cover of the notebook gets. The new one gets hot too, but never so hot that you can't touch it.
I called our local retailers support service, and they said they have no guidelines regarding the issue, and can not take it in for repairs.
I found this pretty surprising, so I downloaded a 3d game (sourbraten or something like that) and tried running it so that there was some processor load on the background. The screen came full of black distortion within a few minutes.
I called Apples support, and they said there must be something wrong with the video card, and the laptop should be sent for repair...
As an engineer working with servers for a living, I find this pretty funny. The support person didn't find anything strange in the fact that one of the notebooks is running at about 80% higher temperature over ambient, he actually said that "temperatures around 100c are fully normal for a notebook". I understand quality control will have some margin in a matter like this, but the difference is just huge!
The main reason I'm still wondering about this despite my mbp being accepted for repair is that we have almost 100 Apple notebooks for our workers, and there are a lot of other employees complaining about the heat. It seems most of the ones complaining received their notebooks in the same batch as me. Do we have to try to get corruption on all of them before extreme temperatures are regarded to be non-normal?

Hi, and thanks for all the answers!
A funny thing happened before I left work. We received a box full of silly gifts from Intel, including a usb coffeecup heater. Well the heater really works, it keeps your coffee hot until you drink it (mine was really hot for over 20 minutes)!
What's even funnier is that the notebook under load was about as hot as the coffeecup heater...
The notebook, and the one I compared it to where both updated with the latest firmware, and all automatically available operating system updates.
I'm an IT engineer, mainly maintaining fairly high end servers. I have however toyed and built computers for well over 10 years, and have quite a bit of experience with them. For example having two fully identical computers next to each other with the same configuration and running 100% load on each should result in almost the same processor temperature. In this case the cooler computer had a faster processor which should actually mean it runs slightly hotter (though speed actually does not have a huge impact on processor temperature comparing to voltage).
So what could cause the differance in temperature? There are really only a few possibilities:
- The hotter ones processor does not get good contact with the cooler
- The hotter ones fan(s) is not running as fast to remove air from the case
- A fan is broken in the hotter notebook
There are small variances in heat output between identical processors, but the differance would only be a few degrees.
I can hear the fans in both computers when they are under load. The hotter ones fan is actually running at a clearly faster speed then the cooler ones. The only logical explanation is that the heatsink does not have good contact with the processor. Due to this it can't really dissipate the heat however fast it spins the fan, and the processor remains hot. This does not explain why the case is so much hotter too... :O
I read the link you have regarding Apples guidance to temperature, but they are not actually saying ANYTHING in that article. Actually they say more in the detailed specs page you can get on the notebook on apple.com (sales). There they mention what the ambient temperature for operation can be.
Now when I called Apples support, I was told it is fully normal for a macbook pro's processor to operate at 100c. However according to Intels specifications 100c is the maximum temperature the processor is allowed to reach under any condition (this is the highest max temp on any processor I have heard of by the way). So what apple is basically saying, is that it's perfectly normal for my processor to run hotter then Intels highest allowed temperature? To add to this my ambient temperature while testing was 21c (14c under the maximum temperature allowed for operation). So what would happen if the ambient temperature went up to 35 (which is not even an especially high temperature...)? The processors temperature would most probably raise to over 110C!
Just like Intel has a maximum operating temperature for it's processors, hardisk manufacturers have a maximum temperature for their hardisks operation. Having a case too hot to touch does not make me feel very confident that the hardisk is operating under a temperature within the manufacturers limits.
But still Apple believes this is ok untill your notebook get's so hot that everything on the display becomes corrupted! Also their page concerning the macbook pro's operating temperature does nothing else then try to convince you that it's normal that your notebook burns you!
Really makes me happy I got applecare
edit:
btw, thanks for the info on the hardware test. Unfortunately I already packed the notebook for repairs, so I can't try it. Will defiantly remember it for next time though!

Boot Camp on MBP internal drive (disk1), attempts to boot off CD bay drive (disk0).

Hi. I have an early 2011 MBP running the latest version of Mavericks with two internal SSDs. The HD bay has a 1TB (disk1) and the CD bay has a 512MB (disk0). Boot Camp is installed on the 1TB. When I boot up the system and hold down the Option key, I see Windows as a boot option. If I select it, however, it starts to boot and then goes immediately to a black screen with a white underline cursor blinking in the upper left. It remains like this until I reboot.
After spending a lot of time looking into the cause of this problem, I've come to the conclusion that the system is confused by the drive in the CD bay and is attempting to boot from it before it attempts to boot off the drive in the HD bay. I installed Boot Camp originally by using Boot Camp Assistant to partition the drive and then using WinClone to copy over a previous Boot Camp partition. I'm pretty rusre that as a result, one of the following two things is happening:
Whatever setting Boot Camp Assistant made to tell the Windows install DVD to boot first is still in effect and Boot Camp is attempting to boot from the CD bay.
The Boot Camp partition is set from the previous drive it was on to boot from disk0, which is now being assigned to the drive in the CD bay.
To test these theories, I've unplugged the drive in the CD bay and rebooted, at which point Boot Camp boots perfectly off the drive in the HD bay.
The drive in the CD bay is set to a single HFS+ partition. I've looked at the GPT and MBR on both drives and they seem fine (the Boot Camp partition is bootable). Does anyone have any idea what I'm missing here?
Thanks in advance.

Still having issues, any suggestions would probably be helpful.

Dangerous temperature- solution please?

So I have recently started trying to game, and yes I'm trying it on my MacBook Air. I have no intention of getting another computer. I've been trying to use laptop fans to keep it cool, but I recently have used the iStat app while playing my games, and I realize I'm getting CPU temperatures of 90º+ C! I understand that these temperatures are life shortening, and would like to use this computer as long as possible. I don't want to stop my gaming either though, can someone please recommend some way of keeping the temperature in the safe range?

As you will see the column headed "Load" includes a lot of temps in the 88 to 95 celcius range. The variation depends on a number of factors, including which processor and what tasks are being undertaken by the processor.
Hope this helps.

Should I expect a lot of noice from the internal cooler (fan)? Thx

I hear a strong noice from the cooler when the equipment has a high temperature... (like an airplaine enginee)
Can aomeone tell me if it´s a normal behavior?
Thanks much.
Leandro

ABSOLUTELY normal. It will be louder when the computer gets hot, thats what it is supposed to do. The fan kicks into higher gear to keep the processor cool and remove the excess heat from the case. I only ever notice my fan when I watch videos for a long period of time. I never hear it any other time.

Mac-mini Internal Drive operating temperature

What temperature should my internal drives safely operate at? I have an SSD, recently installed, plus the original 500GB internal SATA drive. I'm getting readings of 56°C (138°F) at the moment, which DiskWarrior claims is too hot. S.M.A.R.T., on the other hand, says both drives are fine.

What model Mini?
Did the HD have a sensor taped to the drive?
What are other temps? Like ambient, CPU?
What specific SSD?

Clone no longer sees MBP internal drive

When I boot up from a clone on an external drive, the internal drive of my MBP no longer appears in the Finder -
nor does it appear as a startup disk in System Preferences.
In fact, none of my clones are recognising the MBP any more.
The MBP drive is only 3 months old, and Apple branded, and all drives are formatted OS Extended (Journaled).
Everything was working perfectly until recently - without there being any changes to the setup as far as I know.
Any idea what’s happened, and how to fix it?
It’s a mid-2009 MBP running 10.9.4.
(I originally posted this in the Mavericks forum, but maybe it's even more relevant here.)

Apple does not produce any drives on their own - so any "Apple branded" drive would be manufactured by a third-party.
Have you tried booting into your Recovery partition (hold down the command and R keys whilst booting) and using Disk Utility to Verify and, if needed, Repairing your internal drive? Does your machine boot with all of your clones as well as your internal drive, but does not show up on the Desktop when booted from a clone? Have you used Disk Utility to see if the machine actually 'sees' the internal drive?

MBP & operation in high temperatures

I'm looking to purchase the MBP before my upcoming deployment to Iraq and I was wondering if the high temperatures, climate, and environment in general would hurt the machine. Thanks!

elgato, I've carried PowerBooks all over Egypt. Made some brief jaunts into desert areas.
Sand was my biggest concern. I kept the PowerBook in a tied plastic garbage bag most of the time (and kept some spare garbage bags in my carry bag). Same with my camera gear. Didn't have any problems with the equipment. A friend didn't protect his SLR film camera that way and changed lenses several times in dusty conditions. That camera was never the same again.
I tried to minimize the use time in very hot environments, like 54 C one time(but to be honest I wasn't much interested in using the computer in that heat).
Fortunately, I was able to work with the computer and photo and video processing in air conditioned hotel rooms or on air conditioned Nile cruise boats. Your experience may vary.
Good luck and stay well.

MBP 15" Cooling fan issue

For about the past few weeks, my MBP's (15", C2D 2.16 GHz) cooling fans have been running almost constantly. I fear this might have something to do with the battery what seems to be decaying rapidly. Has anyone else w. this model had these similar issues?
Here is my battery info from System Profiler:
Battery Information:
Model Information:
Serial Number: Sony-ASMB012-358d-3d
Manufacturer: Sony
Device name: ASMB012
Pack Lot Code: 0003
PCB Lot Code: 0000
Firmware Version: 102a
Hardware Revision: 0400
Cell Revision: 0303
Charge Information:
Charge remaining (mAh): 1603
Fully charged: No
Charging: No
Full charge capacity (mAh): 1935
Health Information:
Cycle count: 150
Condition: Check battery
Battery Installed: Yes
Amperage (mA): -3459
Voltage (mV): 11200

No such problems here. Have you tried opening Activity Monitor and clicking on the CPU% column to sort descending and see if anything is using a considerable amount of CPU time? Have you used the Console app in the Utilities folder and checked the console log to see if there are a multitude of repeating entries and seeing if you can identify the application or process causing the repeated entries?
I don't see any reason why the battery should have any bearing other than constantly running fans and CPU processes might reduce the time you can run on the battery. If you were to remove the battery the processor speed would drop automatically which would reduce overall speed and amount of generated heat.

New MBP Internal Storage options

Greetings,
I'm looking at possibly getting a new MBP, but am curious about the HD options. Would you go with the 500Gb 7200 rpm, 750Gb 5400 rpm, or would you go with the 512Gb SSD? Is the SSD worth the extra $1100? I have a 500Gb in my Core 2 Duo and even thought about keeping it and replacing my HD with an aftermarket SSD that is probably cheaper than the Apple OEM. Thoughts from the gallery?

Well, no matter what, the SSD will always be the fastest one available. The 750 GB is also good for large storage, and if you don't need all that, you can always get the 500 GB.

The internal cooling fan(s) on my MacBookPro have quit running. Possible reasons why?

the cooling fan(s) on my MacBookPro have quit running. Looking for answers to this problem

Now that I think about it, I wouldn't even try inserting a disc or even using it. Without fans you could very well fry things on your mac (as Allan Eckert said) that might end up costing you more. Turn your mac off and don't use it again until it gets looked at.

Will swapping out the internal hard drive in my MBP void the warranty?

Hello, Basically my question is, Can I change the internal Macintosh HD hard drive in my 15 inch Uni-Body MacBook Pro (Express Card slot) without voiding the warranty? If not, could I take my computer to an authorized Apple Service Center and have them change my HD?
Another question, My internal HD is 250 GB, I was wondering what is the size limit for my machine? I would personally like to fit 1TB in here

Yes, you can swap it without voiding the warranty. Instructions are in your user manual.
Western Digital has just released 750GB and 1TB 2.5" drives. They are taller (12.5mm) than the height specification for MBP internal drives (9.5mm), but it has been reported that they will fit anyway.

2011 17" MBP heating problems

Hi,
I am completely new here, have read a bit the past few weeks on this particular subject.
Sorry for the long story and thanks in advance
I have a 17" MBP with 4gb and 2.2ghz.
This was a replacement model since my old 2009 MBP had heating issues (as well).
My MBP easily runs up to 80/90 degrees celsius while running close to no applications.
I went to the apple store and told them I would reach 80+ degrees easily when watching a streamed 2 min movie in chrome. They told me not to use chrome and that is was normal.
I also experience a lag after a few hours of heat.
On my old MBP I had adobe cs5 or 4 which caused it to overheat a few times. I want to install CS6 because I am building a new company and need those programs.
I went to the geniusbar in Amsterdam and they told me heating up to 105 degrees celsius which I think is 203Fahrenheit are still ok. At the geniusbar the genius said 140 still exists for the CPU.
My problem is that at certain points of my laptop it just gets too hot after a while. It gets dangerous to even lift my MBP when walking to another area of the house.
I easily reach 6000rpm and 80/90 degrees Celsius. Applecare US (I called them for 2nd opinion) told me temps were a bit high. Amsterdam tells me it's normal.
What can I do, are these temps normal?
What will happen if I install adobe and run it alongside some other downloads or streaming movies.

Temperatures in a MBP are a function of the activity that is occurring with the CPU/GPU. High levels of activity create high temperatures and 80-90 c. is not unusual for certain applications and situations. Note that there are temperature sensors that will shut the MBP down if the temperatures exceed safe operating limits thus preventing damage to tye MBP.
If you wish, install iStat pro which monitors that internal temperatures and fan speeds. Also open Activity Monitor to show All Processes and %CPU to show values from high to low. Post images of them when your MBP is operating at 'high temperatures' such as these from mine for evaluation:
Ciao.
