    Hi All,

    I have a 2011 13” base model ( upgraded to 8GB RAM) which I use at work. I use win7 with parallels 6 at my work (I configured parallels to use 3GB of RAM and 2 processors and it is a boot camp partition).
    The temperature idles at 70C with default fan speeds and when set default to 3000 using smc fan control it idles at 60C.
    So my question is : what are the effects of running fans at minimum 3000 rpm all the time(8-10hrs a day), I am sure It won’t damage anything besides the fan , but inputs are appreciated.
    Or Should I just leave at default fan speeds.
    If I leave it at default speeds it is warm to touch on the left side of the keyboard.
    And what is the lifespan of fans in these notebooks?

    Running it at a higher fan speed shouldn't be an issue. They are designed to handle the load and I used to have my MacBook at 3000 or 3500 rpms for days and didn't have a problem. Don't worry about putting stress on the fans, but I would suggest opening up the computer and using compressed air to blow some of the dust out like once a year. It really helped with the temperature in my MacBook pro. Just be careful not to damage anything when you do so

    When connected to my external monitor in clamshell mode, I set my fans at about 3k-4k rpm. I never had a problem and my macbook is more then a year old. Like mentioned above, a good cleaning while putting the fans higher is always recommended.

    i think your fans should last a few years spinning at that speed at all times. if you have apple care i wouldnt worry about it.

    Most mechanical things have a better life when they are run at a constant speed rather than changing speeds all the time. I wouldn't worry about it and they might even last longer.

    alright thanks guys... i am planning to get an incase case and will set it to 3000 rpm by default just to make sure it doesn't get hot.
