109°C (228°F) CPU temperature, fans idle @ 2k rpm!!!!!! I'M SO MAD

Yes i have and im still testing. i had, have watched videos from web sites that are about 45mins long and DVD that are over an hour. i am using Logic Pro 8 which uses a good amount of CPU. well case being, using those areas that ive mentioned, it doesnt heat up my computer as much as before which i am glad about it 🙂

Has there been a resolution of some kind to the heating and fan issues? My fans only get to 2000rpm, as I've read elsewhere. I don't do much heavy duty work, but at what temperature should the fans start to rev up?

Mine begin to rev up between 80-85ºC. This is what a normal MBP should behave like. You should not see temperatures much higher than 90-95ºC for any extended period of time.

Thanks for the response. Short of playing a video game, what is a good way of testing whether or not the fans kick in, even at 80-85C?
Thanks

A few of us documented these steps in the 'screen turns black when gaming' thread, but here's what you can do. Bear in mind that symptoms my not occur immediately, but they have on every machine I've tested (around 30).

1. You will need software to monitor the cpu temp - I suggest the 'Istat' widget : http://www.islayer.com/apps/istatpro/
2 You also need a tool to make the Mac push it's cpu - easiest way is to run CPUTest from: http://www.soft32.com/download_199513.html
3 Ensure your MBP is sleeping, and then wake it up.
4. Run the cpu test whilst monitoring the cpu temp in Istat. I'd recommend the 'big' test, 10 repetitions, with 2 instances running.
5. You will find that the temperature rises, but the fans stay at around 2000 rpm, even when the cpu crosses the 100 degree mark.
6. Stop the test, turn off the computer and reset the SMC (battery out, power button for 10 secs)
7. Turn on the computer and run the cpu test again.
8. Note that the fans now spin up when the cpu goes over 80-85 degrees - normal behaviour.
9. The problem will re-occur after the machine has slept and the whole process of resetting the SMC will need to be completed again.

That's it - let us know your findings. Just don't let your cpu stay hot for too long....

Based on additional communication I've had with Apple, I can say that Apple is fully aware of the behavior I described in previous posts. That fan control behavior is considered normal at this time.

My opinion is that a future update, probably an SMC firmware update, will change that behavior.

As for why an SMC reset changes the behavior, I do have a guess. If the fan is controlled by a standard PID (or PI) control algorithm, the calculation is affected by historical as well as current temperature readings. Resetting the SMC erases the history. The control signal to the fans is then different until historical data builds up again. Again, this is speculation.

By the way, I retested with the latest version (4.6) of Hardware Monitor and there is no difference in the overall results.

This is not to say that everyone posting here is in the same situation. A previous poster described his machine shutting down consistently at 90 deg-C. That sounds like a hardware problem.

Firstly, I see that the SMC reset for this computer doesn't entail taking out the battery but doing the smc reset as is done with the Macbook Air. Am I wrong about that?
Secondly, is there anything more simple I can do, like watching a video for a long time or other activities that will test whether the fans will kick in at a certain point? As of now I have been a light user and I have seen the CPU go to about 70C watching videos on you tube.
I am not a heavy user, but would like to know if I have a hardware problem because I have only had the computer for 2 weeks.
Also, has anyone figured out how to get rid of the wave effect when using the sidebar to scroll pages in Safari or elsewhere?
Other than this, so far I love the computer.

Same Problem here.

I have installed bootcamp. i played Crysis for over 5 hours. After that i went on OS X. For 2 hours just surfing the net.I opened handbrake and the macbook RUNS at 89 degrees Celsius. and the fans i could not hear them. maybe they are on 2000rpm. Thank god i realise it soon, and stop handbrake encoding.

After that i came here and read that others have the same problem. so i reset the SMC. after resseting SMC . the 1 time i opened handbrake the fans start rolling at 67 Celsius .I stopped the encoding and start it again after 5 minutes. AGAIN the macbook reach 89 degrees without the fans rolling from over 2000rpm.

Please apple fix it. We don't want our MBPs to be burned 😟 😟 Please realise this problem and give us a fix.

When you say that the computer was running at 89C, was that with the dedicated 9600 chip or the 9400 integrated?

For example, is watchng a dvd and at the same time maybe playing a video on YOU Tube sufficient to push the temperature up to where maybe the fans will kick in. I don't know how to encode or even what handbrake is.....Yet.
I presume that do to any test, you must use the higher performance chip, 9600.
Thanks

Watching a DVD won't do much.

Use multiple sites with flash and youtube.

Any suggestions of sites that run intensive flash media? Not quite sure what flash is, though I understand it's video content on web sites.
Sorry but new to this.

hi david waddington

I really dont know to much about restarting the MBR (i believe thats what u call it) but ever since i deleted my OS and reinstall the OS and apps everything has been working GREAT. the temp from my MAC is at 88 degrees and sometimes 92. i sometime see it go higher then that when i deleted some files that are about a gig or less (depends how much the files are). either way, the temp is between 88 to 92 degrees.

from what i believe, i believe that when first buying the mac u should delete the OS and reinstall it. thats what i usually do when i worked in the IT department.

HY!

I've the same problem here with my MBP 2,53. As im using Handbrake, my MBP's CPU burns into 110 Degrees Celsius and the Fans are running about 2K RPM. The surface of the MBP is burning hot!

Please Apple, fix it. -And by the way: please fix the flicker and blink-ISSUE!! THX!!!

Consider it done, baby!
