    Hi

    I just bought a 13 inches alum macbook pro...

    I'm wondering why does it run @ 2K rpm even when my comp is freezing ( like 25C)...

    I used to own a white macbook and most of the times it was running @ 1K..

    Never saw my new macbook with less than 2K rpm...

    With 2K, I can hear the fans so it's a little annoying... Why does Apple keep getting worst...

    And that freaking HDD cliking.. WTF, I used to not have this on my older macbook.

    But, any explanations on the 2K? Do your macbooks alum run at less than 2K RPM sometimes?

    2000 RPM is the idle speed for the fan. It will always run at the speed on idle.

    But on the old macbooks it used to be 1K...

    @ 25C, I'm sure the computer would do fine with 1K....

    2000 rpm is the normal speed for aluminium MBPs.

    You can use FanControl to lower the base speed if you want to.

    Why do you think it's at 25°C?

    It's 1800 RPM at idle on the pre-Unibody models.

    Is it me or @ 2K you can hear your computer running?

    @1K, with my older macbook, I couldn't hear a noise.

    The newer models at 2000 RPM are a little quieter than the older fan at 1800 RPM.

    I can't hear my uMBP's fans at 2k. All I hear is the HDD spinning, though, still not very noticeable.

    kk thanks. I guess I'll live with it... The fans doesn't worry me that much..It's more that stupid HDD clicking they have added.

    Oh so maybe that sound I'm hearing is from the HDD?

    It's called Sudden Motion Sensor, but it is available in Macs since the late PowerBooks, so it had to be in your MacBook.

    If it's that loud, you could let have Apple a look at it, maybe the HDD is failing. Stupid, I know.


    HDD is on the bottom left, CPU fan is between the F5 to F7 key or so.

    Oh so it's not suppose to be loud?

    It's not that loud but its noticeable... Do you think it's failing?

    I think I read it's pretty common on the new aluminiums...

    Why is SSD not affordable! :(
