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!

    Did you try to reset the SMC, I had a similar issue where my brand new MBP's temps were increasing but the fan speed didn't move beyond 2k. Once I reset the SMC all was well. Additionall download SMCFanControl This handy little app will let you manually adjust the fan speeds. Depending on what I'm working on, I'll default the speeds to 2.5k or 3k (or faster if I'm working on an intensive task)

    Sorry I missed the point of you resetting your SMC

    and no, i won't install a app which regulates my temperatures. i don't want to swallow all this pathetic bugs that apple dishes me... i want finally a solution!

    I provided a solution if that's not your cup of tea, which I can respect. Your options are limited to returning the laptop or getting it repaired/replaced if its beyond the return period.

    There's really little else anyone here on this board can suggest or recommend short of calling apple or loading SMCFanControl I use that application not because my machine is defective and its a stop gap solution but I find that manually adjusting the fan speed is superior to letting the mbp control it

    Just to make sure the problem is not a bug in iStat Pro. Are you saying that after putting the computer to sleep you do not hear the fans revving up again no matter how hard you push the CPU? If that is the case, have you called AppleCare and asked to talk to a technician so they are aware of the problem?

    i think the guys at apple care won't tell me anything else then reset the smc, pram and repair the disk permissions. getting it returned/"repaired" won't avail, cos i think all MBPs are affected by this. there are many others which have exactly the same problem.

    No, they won't. Since you have already done all the things a 1st tier support employee can suggest you and the problem persists then just ask to get the call escalated to an engineer and report the problem. The only way of getting the problem resolved is by letting them know about it.

    No I disagree, many of us, including myself do not suffer the problems that you do. Initially when my MBP was new, it did have the problem as I mentioned but resetting the smc solved it

    So like to reiterate my MBP like others is problem free. I don't say this to rub it in but to refute the statement that all MBPs suffer this malady

    Did you ever install 'Hardware Monitor'?

    Additionally, I found this on the web, maybe there's some correlation, will dig deeper into that:

    The application displays a warning that I am using an Intel CPU with out-of-date microcode and that the per-core temperature sensors may stop working after the system is waking from sleep mode. What should I do?

    This problem is caused by an internal design flaw affecting the first generation of Intel Core processors. The Digital Thermal Sensors may stop working when the processor returns from a C3/C4 power saving state. Intel has corrected this hardware bug in later versions of the CPU.

    As a workaround, you should install Apple's firmware updates for your particular Intel-based Macintosh model. This will fix the problem in most, but not all cases. It is recommended to install the firmware update for the Boot-ROM, as well as the firmware update for the System Management Controller (SMC). To download the firmware updates from Apple, please see the following table:
    NOTE: Macintosh systems built after September 2006 are no longer affected by the aforementioned problem.

    Intel refers to this hardware problem as Erratum AE18. For detailed information, please see Intel document 30922204.

    Many of us do not have any problems of this sort. If you are truly having this kind of radical fans problems have Apple replace the unit and be done with it.

    My fans keep my CPU cool at all times. I have not had one overheat issue.

    I followed your steps to see if my machine was affected and it is. I did a test by using the flatout2 demo. I knew that it would heat things up, I played for a little while then exited the game to see that the fans were working great after the smc reset. I then allowed the machine to go to sleep and then I played flat out 2 again and the fans were staying idle at 2k. So I did another SMC reset and all works good again. I bet alot of people have this problem if they would follow your steps they would also notice it.

    Hi, I have the same issues. But i dont need to change the gpu for this to happen. Only putting the MBP to sleep once, results in faulty fan control. When I reset the SMC, and test with /dev/null, the fans kick in at about 75 degrees celcius and stabilising at 82 degrees celsius at about 3000rpm. But when I turn the MBP to sleep, fans stay 2000rpm and temperature seem to rise up much faster. Although the fans, after about 15 mins, seem to start rising in their rpm but very very slowly, reducing the temperature to about 95 degrees celcius.

    While the fans were stuck at 2000rpm, I booted into BootCamp/Vista and the fans spun up immediately.

    So the issue does no longer seem to me being a firmware issue but an OS X issue, more likely a 3rd party software incompatibility, maybe between OSX, Hardware Monitor and iStat (which apparently does not go away even if you deinstall the latter two).
