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

this is a issue since the new MBPs were released. as soon as the CPU temp reaches ~55°C the fans start slowly from 2000 to 6200rpm if the CPU is on maximum usage. this is absolutely ok. BUT, if you put your MBP to sleep, log out or change the GPU, something happens to the fan control! the next time you maxing out your CPU power, the CPU heats up to 109°C and the fans keep running at 2000rpm

if you reset your smc everything is fine until you put your MBP to sleep (...) again. seriously, what is this apple? this is so so unbelievably pathetic!
the newest "placebo smc update" didn't change anything! it changed not even one thing what it promised, LOL! stop messing around apple and do* something!

Anyone have updates/news about this "little" problem? Or shall I just accept the fact that my computer is likely gonna meet an early death, caused by daily overheating?! 😉

no updates, still the same BIG problem. apple will do nothing against it because there are not enough people complaining. tho every MBP is affected, lol.
apple = nice design, nothing else.

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.

i think that its wise just to reinstall the OS and APPS

The question is clear for me.
I have accepted this issue in full scale after upgrading my MacBook Pro to MacBook SMC Firmware Update 1.2. There were no any problems with fans before.
So I suggest that the SMC Firmware Update 1.2 is buggy!!!!

Very interesting thing is that Apple have removed this update from there site:
http://www.apple.com/downloads/macosx/apple/firmware_hardware/.
May be Apple will give us the new update ?

Important addition.
I have made upgrading with MacBook SMC Pro Firmware Update 1.2!!! And Apple have removed it but leaving MacBook SMC Firmware Update 1.2!!!

So for my opinion MacBook SMC Pro Firmware Update 1.2 is buggy.

I checked my MBPs serial number and its manufactured the third week of 2009!!! So its brand new and I have got this issue, too! I don't know if It already shipped with the new SMC etc, maybe it came with software update... resetting the SMC resolves the heating issue, but after a standby my fans won't go over 2000rpm

I got the latest things here:
Boot-ROM-Version: MBP51.0074.B01
SMC Version: 1.33f8

any way to downgrade as people are reporting its the new SMC?

Feb 12, 2009 8:08 AM in response to preller

Just chiming in with the same problem. I saw my core temp go to 108 with fans still at about 2500 rpm.

Also, I just had to hard reset it after it froze at about 66 C.

This laptop has frozen several dozens of times in the past few months, far more than I've ever experienced with any computer. =[

When I reset SMC and PRAM, only the right fan behave like normal. The left fan stays idle @ 2000rpm, even when forcing max rpm with SMC FanControl. Earlier both fans ran like they should after a reset, but since yesterday only the right one acts normal.

Feb 17, 2009 7:46 AM in response to preller

Interestingly I noticed my fans suddenly kicked in while working with photoshop... It was just a small noise I noticed so I started smcfancontrol and in fact they were at about 2900rpm... I put the MBP under heavy load and the fans went up to 5900rpm, they were a bit late but the CPU didn't go hotter than 94°C! I didnt have any problems yet that my MBP suddenly shut down or crashed due to overheating! I'll watch this the next weeks as I normally had the same problem with overheating after standby!

Incidentally, my MBP fans have been moving in the 72-75ºC range lately as well. They never used to until >80ºC. I've been running the 9600GT whenever possible, and I watch the temps and fan speed through iStat menus. After watching some clips online with some background tasks running the heat got up to around 75ºC and the fans kicked up to around ~2400RPM, bringing the temp back below 70ºC.

If this isn't normal behavior, I don't know what should be?

Hello all,

Interesting thread. I decided to try it on my new from the Apple store in Delaware 4 days ago MacBook Pro. New, but actually built mid November, so the serial number shows. So what do you know, same problem, entirely repeatable. From sleep, run stress test, fans don't start to ramp up till 98C or so, then speed up only slowly. After SMC reset fans start to rise before reaching 80C, go to 6100, bring temps down to 75C, then fans slow and maintain 75C. Sleep again, then 95 and idle.

I'll try fancontrol, but I really shouldn't have to.

Today I got my computer back from repair shop. They have fixed the left fan but the main problem is still there. Back to smcFanControl I guess...

My Macbook Pro Unibody 2.4 late 2008 had the problem. I noticed within a week that the fan-control was rubbish especialy in Vista. I also had strange popping sounds coming from the speakers for no reason.
I called Apple support they said that it could be a faulty logic-board.
They adviced me to contact the reseller (Dynabyte) where I bought my MBpro.
So I called Dynabyte explained what was wrong. They orderd a new Macbook pro from Apple and allowed me to use the defect one until the new Macbook got delivered.

My new Unibody Macbook Pro 2.4, prroduction week 5 2009 doesnt's seem to have the problemen.
Fans run fine.
The strange thing is that it has exactly the same EFI and SMC firmware versions.

I have this issue as well. Using SMC to control the temps now when I need it.

I had my logic board replaced after 3 days of use (might be related, might've fried my system since didn't even boot, no apple screen, no screen backlight, reset cmds didn't even work) and still have similar now with heat. Paranoid about it as ****. I've been using the 9400M. When the CPU is working hard I notice the fans slowly go faster when it goes over 85-95°C but that's just ridiculous. Does Apple consider that safe?

Light use (20% CPU use) the temps float around 50°C for CPU and 45°C for GPU though with the 9400M. With the 9600M it's about 5~10°C more.

Is the CPU A in iStat pro the CPU Diode temp or the Cover temp?
