    Nasty Whistle Noise

    Hello,

    when I am flying, I can hear a whistle noise which comes from the back of my server pc. It is not the speaker or the sound card.
    I think, it could be the network. It's only to hear when I start FMGS on my 2. PC in my network.
    If I close FMGS 50.0 on the 2. PC, the whisle noise stops on my FMGS Server PC.

    It's a really nasty noise.

    My configuration

    1 PC: P3D 4.2, FMGS Server 50.0,
    2 PC: client PC with FMGS 50.0

    FMGS works well, no other problems, homenetwork is okay...

    Any ideas? Maybe the power adaptor? Not enough power?

    Best regards, Thorsten

    the sound module software outptus some "electrical" noise as well as air conditionning noises. Those are at a rather high volume by default and can/should be adjusted in the sound module options.

    Electrical and air conditioning are off. I think, it is something else....

    If it's not a sound played from the soundcard then I'd bet it's a switching power supply circuit under stress.

    Long story short, switching circuits switch above 50Khz, which can't be heard by humans, but with age and thermal stress this can drop to audible high pitch frequencies. It might be ok for a very long time but eventually your PSU, motherboard or video card will die (depending on where that switching circuit is).

    You could confirm it by running a stress test on your CPU or video card which should cause an equivalent sound when more load is requested and you can confirm it's not the network by pulling the cable out.

  5. Thanks Conner thanked for this post
