    Hi i just got a Black C2D Macbook and the CPU fan runs about 997-1100 RPM when idiling, but the fan is still quite audible. Also there is no noticeable increase in fan noise until the fan reaches atbou 3500 rpm. Is this normal??

    Can you hear them over music? The MacBooks I've worked with have almost been silent (all editions) and I'd have to purposefully listen to hear the fans.

    Yep.

    I have a 17" MacBook Pro and yes, it's silent. Even when the fans are running, you really, really have to listen hard to hear them.

    Depends on two things. How good your hearing is and how much ambient noise is in the room. My hearing is bad and I live in an open-plan house with 3 kids so, relatively speaking, my MacBook is silent at any speed.

    Your fan only does 1000RPM at idle?

    Mine has never gone below 1800RPM, even just after I've turned the laptop on. It's completely silent though (apart from the CPU whine when running on mains power).

    Off the top of my head, I though about 1600RPM was normal with a fair chunk of leeway. :)

    If i play music, i cannot hear the fans. Usually my television or any sort of conversation, or music will drown out the sound of the fans. My Macbook does idle at around 1000 rpm but only becuase i'm using FanControl. My idle temps range from 46-55 degrees celsius.

    I was under the impression that smcFanControl couldn't go below the stock speed set by Apple. Mine starts at 1800RPM.

    There are two different fan control softwares available. smcFanControl and FanControl. FanControl will allow you to set your minimum fan speed at 1000 rpm.

    Mine is actually very quiet most of the time. I can only hear something when I put my ear next to the keyboard but apart from that only when I'm putting it under a big load. I have the last generation mid range macbook Core 2 Duo if that makes a difference. I haven't looked into it much but it seems the current rev. macbooks are a bit louder.

    Mine is almost always silent, as in dead silent.

    The exceptions are when I play games, open Aperture or when I print.

    Does anyone know why my fans go crazy whenever I print a document?:confused:

    mine is quite if it is level, but if I have it in my lap, or at an angle, the fan is much louder.

    this might sound quite silly to someone with more intelligence than me, but are drivers PowerPC/Intel binaries, or are they just files controlled by the OS. Beacause if youve got PowerPC Drivers, that may cause the fans to run. When i run PowerPC apps on my macbook the fans run, but apart from that, its almost silent.

    notsofatjames, I think you're getting a bit confused. Drivers are needed by the operating system and therefore they need to be readable by Intel or PowerPC chips (or both). Running PowerPC software on an Intel machine requires Rosetta, which is a relatively complicated back end mechanism set up by Apple and requires quite a bit of CPU cycles and RAM. It's normal for apps running in Rosetta to place more strain on your Intel machine and therefore for the fans to need to spin faster to keep the thing cool. I hope that makes a bit of sense. I'm pretty hungover right now so I'm sorry if I just started rambling. I can't stop thinking about greasy hot chips.
