Will MBP's Fan Wear Out if Constantly Spinning at 3500 RPM?

    I'm prepping my Macbook Pro for daily usage now and moving around all my documents, etc.

    What's the normal fan speed that you guys usually use during your normal daily usages and what temperature do you expect when you are using it everyday?

    Would the fan wear out if I set it to 3500RPM indefinitely when I use it using SMC Fan Control?

    Ive read some post people keeping there fans idling at 4000rpms for like 4 years without any issues. So im thinking we are good. I keep mine at 3000rpms at idle. Then bump it up when i need too.

    Keep the fans clean and they're work for the life of your laptop.

    Dirty fans cause them to work harder, cause friction, and will ultimately make then fail.

    I set mine for constant 3000 minimum. (it seems to keep things cool, but doesn't make any more noise than the default)

    Should one of your fans fail, they are cheap and easy to replace. However, should your logic board fail from chronic heating, you can go ahead and throw your MacBook Pro in the garbage.

    Constant heat = hardware death. I don't know why apple doesn't acknowledge this.

    I think it should be ok. I have a black macbook core duo 2.0, the fan kicked into 6000+ rpm every time I used the cpu intensively (like watching clips from youtube or hulu). It happened like gazillions of times and my macbook is still working fine (4 years old with no repair at all). So I think that you don't have to worry :cool:

    Electric motors are pretty reliable things, they'll handle that RPM for a long time easy.

    i say, i would rather have to buy a new fan, than having my MBPs processor burned out

    How would one keep their own fans clean/replace their fans on their Macbook Pro?

    Take the bottom cover off, hold the fan with one finger and blow on it with a can of compressed air. Reason you need to hold it with a finger is prevent it from spinning.

    I keep my macbook pro on default 2000 rpm. you really do not need to set the threshold higher, but you can do it to keep your macbook pro cool(er).

    Yeah I've got mine set for 3500 while on battery and 4000 while plugged in. I think I might bump it down to 3000 and 3500 though just cause as I've went on using the notebook with the fans that high I've noticed it doesn't even get anywhere near as hot, so even if I bring it down a little, it should still be a reasonable level haha

    I keep it at 3,500rpm under normal conditions, and let the MBP itself spin up the fans when it becomes hot (when using Aperture, Adobe stuff, etc).

    Mine runs around 2500-4600 rpm since 8 month. It's fine.
