    I just purchased a new Mac Pro 8 Core 2.8GHz. I wanted to know if its normal to hear the fan's running when the computer is idling. I have my computer placed on top of my desk and is less then 2 feet away from me. I am just checking to see if this is normal I have never owned a Mac Pro before.

    The fans aren't making a knocking noise or sqeeking noise. You can just hear them running.

    Of course.

    Wouldn't it be bad for the system if they weren't? :rolleyes:

    I don't hear mine at all except on initial boot/wake.

    But that's probably because I came from a vaccuum-cleaner-esque PC.

    I can barely hear mine, it doesn't bother me.

    Sometimes I turn on fan control for ***** and giggles and turn it up to 3000 RPM, quite a loud machine at that point.

    I had a slight knocking noise on mine and exchanged it for another one which seems to have no knocking noise. UPS guys don't usually take good care of packages so I made sure that they fished out a clean package at the Apple store. I'm sure the sales guys were cursing me out when I left cause the Mac Pros are a bit heavy.

    I have no knocking noise, I just hear the fan's running maybe because I am not use to the sound. having 2 Macbook Pros for a while I never really heard the fans in them until it starts getting hot.

    Do you hear the fan's running on the new one you just got ? also is yours on your desk, or on the floor ?

    Sitting right next to me on the desk, like a foot away.

    I can hear them, but they're very, VERY faint. Almost silent.

    On your Mac Pro 2.8 Octo setup, do you run just the os on the raptor? How do you like it?

    Mac Pro Fan Noise

    Same problem here, though I do have a knocking. It gets really loud sometimes, and it sounds like the fans are revving up and down in RPM in about a 2 to 3 second cycle. This noise is so annoying! I have packed it up and plan to return it for a full refund.

    If you are using a Mac for pro audio work and you cannot put the computer in a closet or different room altogether, a Mac Pro is not a very good choice for silence. Music production or mastering requires the utmost quiet. It is definitely quieter than your average tower, but it is also not nearly as quiet as an iMac. The iMacs are almost completely silent, at least 20 decibels quieter than the Mac Pros. You cannot hear an iMac on unless you get very close to the machine and put your ear near the housing. You can definitely hear a Mac Pro from 10 feet away in a quiet room, even if it is not a defective one, but it is still fairly quiet.

    You have posted that exact same wording in at least 3 threads now.
    Please don't spam.


    I'm kind of skeptical about a sweeping statement that "Music production
    or mastering requires the utmost quiet". The second you press a key on
    your keyboard, click your mouse, or even breathe, you create some noise.
    Noise is unavoidable.

    What's important is where the noise is, and its relative level. You merely
    need to keep noise away from microphones (that's why recording studios
    traditionally had a separate room for the mixing desks etc.) and make sure
    it is quiet enough in relation to the music to not affect your judgement.

    If it wasn't for the white LED on the front, I wouldn't know mine was even on. The only time the fans kick on is when I wake it up.
