    How to prevent recording noise from computer fan?

    Sign in to disable this ad
    This is a question for guys who record in a room at thier home. I'm starting to setup for recording and my method is using a fast track pro with my buddy's mic which is a fairly high end one, just don't know what brand.

    But my desktop's a fairly high end one and it's got one of those cooling fans on the side of the case. It's actually not that loud but i DEFINETLY think it will get picked by a mic, especially with the proximity of it to my fast track pro. The rest of my room is pretty silent.

    Assuming i don't have a recording booth set up or sound proofing/treatment in my room, is there anyway i can void picking up this specific noise. I know you all get desktops or laptops so what do ya'll do. My room's good sized and spacious if that helps.

    you could try covering the pc with a heavy duvet while you record but remember to take it off immediately when youre done to avoid overheating. also try getting a long mic cable and move as far away from the pc as possible.

    you have many choices,
    1. move pc out of the room
    2. address noise issue in pc
    3. get dynamic mic and forget about problems
    I spent a vast amount of time (about 10 years ago) struggling with computer noise,
    I was very picky about it, changed all fans for PAPST (expensive but noiseless), here are some info and photo:

    now, it's not only about picking noise when recording, but mostly about having it super quiet, so it does not irritates you when working with music,
    I can hear a fan in my laptop laying 2 meters behind me, when I work,
    my pc is dead quiet,
    it wasn't very cheap, but it does the job

    What cooling systems do you use if you don't mind me asking?

    all passive, just fans and radiators (hd drives are mounted on radiator),
    all fans made by papst, vga - fanless, cpu - don't remember, 'kamikaze' or sth.
    cabling inside the box and air flow are crucial,
    good luck

    Why not get a fan controller and then you can turn it off manual while you are recording?

    Considering that Macs are the noisiest computers I've ever heard, I think that's a horrible idea.

    Back in the day I had a little 5x10 room that I recorded in and my rather loud PC was in there. It's not that difficult to avoid the noise.

    First, position your mic off-axis from the computer. Simple enough. That will cut out a lot of noise.

    Second, simply putting some absorption around your computer with a little space (and not blocking the fan of course) will work wonders. Just get some small mdf boards, or plywood, and glue/staple/tack some absorptive material to them essentially making tiny absoprive gobos.

    Cheap and effective.

    Would you mind explaining how macs are loud in anyway? Are you labeling Macs in general whether towers or laptops? Im curious.
