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!

strange, but i've just sleep/waked my mbp and the smc still works. fans started to accelerate at the 85°C.

I have the same experience. My fan control keeps the temp around 85c or less. The fan speed went up to around 3500 rpm. Is this considered "Normal"?

Update. Just did an SMC reset (perhaps I did not wait a full 5 seconds), booted up, opened two Terminal windows, and did Yes > /dev/null in each and by 85°C my fans were still whisper quiet. Not a good sign. I'll attempt the SMC reset again, but I'm seriously disappointed by this problem. It's such a shame because every other aspect of this machine is working flawlessly for me and it's easily the best Mac I've ever owned. (Other than hand-me-downs, I've had an iMac DVse (the original 400MHz G3, graphite one), 2 PowerMac G4 867MHz MDD's, and an 733MHz G3 white iBook - which is the only Mac that has ever died on me.)

Update 2: Re-did SMC reset and ran Yes > /dev/null in two separate Terminal windows to max out both CPU cores. Temp had to hit 85°C before the fans would really get going. But, at least they sped p faster than usual. Nonetheless, this is a bit disappointing as I'm used to the fans speeding up before 80°C (which you have to admit is a pretty **** high temperature, even for a CPU).

You have no idea how tempting that is. After a successful SMC reset, and then a couple of sleeps, I'm back to excessively slowly accelerating fans. The computer gets past 90°C (under intensive use or gaming... same thing, really) and the fans still won't speed up. Scary. I guess every day before I use my machine I need to do the SMC Reset. Well, I certainly hope a new firmware and/or software update to fix this issue is released in short order.

Instead of resetting your SMC every time you need to run intensive tasks on your MBP, try Fan Control, when running Mac OS X, and this will simply override the internal SMC's fan control and raise your fans according to the CPU temperature. If you need to run intensive tasks on Windows (Boot Camp), first boot in Mac OS X, download SMCfancontrol, in activity monitor kill the process 'fancontroldaemon', max out the fan speed in SMCfancontrol, restart, and boot to Windows. The fans will still be running at how much you have set the minimum fan speed in SMCfancontrol. Hope this helps, till Apple come out with a reasonable firmware update.

to be really truthful. i think that the people that are complaining about the CPU heating up should complain a lot to apple instead of here. i think that the best thing is to just ask if theres some patch files or some type of file that would regulate the fans. example: if the cpu reaches at 85F the fan should go from 2000rpms to 2800rpm. if the cpu goes to 95F, than fan should be at 3600rpm's. if cpu is at 105F, than fan should be at 5000rpms. know what i mean??

Like i said, i think everyone should just complain to apple and techs at apple about this issue. it's very important that this gets solved becauase i know that most people dont want there computers to crap out.

Alright, I give up. My new MBP (have had it for 1 month now) is still crashing and freezing even while using smcFanControl and keeping the fans at 5000rpms. The temperature is at 62 degrees celsius and it is still crashing. Sometimes it just freezes, and other times it brings up a message telling me to reboot the computer. If anyone can help me out I would very much appreciate it. I don't have an Apple store anywhere near me so I can't just bring it in to a genius.

I'm having the same issues too and have posted at the other forum.

I'm so angry right now. I've been talking to the customer service rep for over 3 weeks. And all he can tell me is the engineering team has not gotten back to him.

I'll be demanding a refund because I'm not paying for a defective product.

You might want to start a new thread. Apparently your problem is not temperature related. Or, remember you have 90 days' free phone support (1-800-APL-CARE).

Same problem here - was fine when I first got the laptop, but something in one of the updates messed up the fan control. It used to start spooling the fans up quite quickly when the temp got over 60°C.

Now it only starts slowly speeding up the fans over 100°C. Eventually it does hit 6000RPM and speed up the fans, but it takes quite a while and the system is red hot (can't even hold my finger on the metal over the F1 key).

ive been reading these posting and not one person mentioned to see if theres any dust thats building up within your computer. has one one check to see that? sometimes dust causes the computer to heat up quick. why dont u people see if thats the cause

Dec 30, 2008 11:30 AM in response to Anthony Rizo

Many people are having these issues from the onset.
Isn't dust a little unlikely with a brand new machine?

sorry but you didn't understand the problem...
the fans aren't speeding up fast enough. dust has nothing to do with this.

Dec 30, 2008 1:33 PM in response to preller

i actually kind of forgot that most people did get the new macbook john lol..... to whoever wrote this "sorry but you didn't understand the problem...
the fans aren't speeding up fast enough. dust has nothing to do with this."

yes i do understand for your info. like my old IT boss use to tell me, keep complaining to apple till the problem is solved. stay on the phone with them till they fix the problem. just simple, keep complaining till they get some patches out there to the people to fix the fans.

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