    **oops the title should be ABOVE 2000rpm**

    Hii.
    My macbook pro fans always spin at like 2000rpm, and i know its not like an istat glitch because even when im like gaming and handbraking and video chatting etc at the same time i wont hear the fans go up and my cpu temp will skyrocket into the low 200's.
    and yup this has been for a few months and ive restarted my computer 594098594 times so a restart wont fix it.
    it just randomly happened... no software/hardware blah blah changed it.
    sooo yup help!
    thanksssss

    I was going to say why are you complaining about your fans being so low and quiet, but then I saw the part of your temp being in the 200!! What model mbp do you have?

    try PRAM and SMC reset

    SMC :
    1. remove power adapter and battery.
    2. Press and hold power button for at least 5 seconds.

    PRAM:
    1. Shut down computer.
    2. Upon bootup (grey screen) press and hold command + option + P + R.

    Please specify units! 200 Centigrade, your CPU will catch on fire. I hope you mean 200 Fahrenheit. Still at that temperature, your fans should start to get faster.

    edit ah nvm...try bringing it to an apple store.

    Type 'yes' in two separate terminal windows in front of the genius. That should get the CPUs nice and toasty. ;)

    Never knew that little trick. I have been wondering lately why my fans never go above the 2025 RPM minimum I have set in SMC Fan Control. I tried your little trick, and let it run for about 10 minutes.

    The CPU utilization shot up to 90% almost immediately, and my CPU temp went up to 170 degrees F, before the fans started to increase speed. They leveled off around 2600 RPM, and brought the temp back down about 10 degrees.

    I Control + C'd both terminals, and the fan speed and temp came back down.

    The temp is currently sitting at 135 degrees F. but I still have VMWare Fusion, Entourage, Firefox, and Adium running.

    Thanks for the tip/trick!

    You know, I have 10 terminal windows open, all running "yes" and I'm just barely breaking 160F. My peak has been 164F. Maybe I'll just let it sit while I take a shower and see if it'll get any hotter. My CPUs are running at about 90% constantly, that's for sure.

    I hope you're not writing it to disk as well 'cause it kills your hard drives.

    it's safe to run...unless your fans are busted. ;) If you're scared about it writing to the HD, then pull up Activity Monitor.

    It took my mbp some time to speed up. It seems like it wants to hold it at ~80 degrees C +/- 2 degrees, not even spinning at full speed.

    "yes" loop is safe to run. No data is written to HD, confirmed with Activity Monitor. :)

    if you want to make it extra "fun" you can type whatever you want after "yes" (with a space between "yes" and desired phrase/word. Phrases must use quotes) ;)

    I have several Terminal windows open running the yes loop while converting a couple videos with VisualHub and my temp is sitting around 165F +/- 3F. Fans are hovering around 3400rpm.
