    Reading the 9550 threads from the beginning, grab a drink and a snack then settle in for a few hours reading, 2 is generous, I know one person said it not sure if it was 2.

    Slight when your ears to the laptop, totally inaudible otherwise (without fans on)
    I hear the fans but used to go to raves in the 90's (back when you bought a cassette tape after the rave) so I now live with tinnitus and say pardon a lot :\

    If you want coil whine go listen to a 9530!

    I once heard nearly everyone's got an ear noise when put into a quiet room. I was actually wondering if it was just me, but there's reallye a coil whine. If it were only that smooth flow of air, it would actually remind me of the ocean. Now it's like being at the ocean - with a bigass moscito.

    Anyone else hear the moscito?

    My USB C adapter makes a high pitched whine when it is connected & the laptop is sleeping, but not when it is connected & the laptop is on. Slightly annoying, because when I sleep the laptop is often when I want to sleep myself & don't want the whine!

    Howbout when you multitask four 1080p youtube videos and the fan begins to kick in. That's when the whine occurs with mine.

    Hi. I've the same problem with my XPS 15 9550 (i7, FHD, 16 GB RAM, 512 SSD PM951) and I think it's a problem with the new generation of the Intel CPUs (Skylake). I will sent back the machine to Dell.

    So, a change of the mainboard doesn't fix the problem with coile whining.

    Hi, I have the exact same notebook. With mine it seems to be closely coupled with the fans. I think I might try to replace it one more time.

    I've not noticed coil whine when running heavy tasks (like batch exporting from Premiere/After Effects), maybe I am just one of the lucky ones.

    If you guys could put on 4 or 5 youtube vids at the same time and then describe what you hear once the fans kick off, that would be much appreciated. Is it just a low frequency air sound or is there also a higher pitch accompanying sound

    just tried this for the heck of it.

    - 9550 is connected via Displayport/USB-C to a 3440x1440 display
    - already have photoshop (three files: two small files, one abt 150MB) and indesign (two files) running
    - Edge browser streaming a radio station (adblockers on Chrome won't let allow this stream)
    - Chrome browser with 10 tabs open

    proceeded to open four brand new Chrome windows, each loaded with a different YouTube video

    result: NO CHANGE in barely audible fan noise.

    but this i mean:
    - no "low frequency air sound"
    - no "higher pitch accompanying sound"
    - if i put my ear very close to the notebook, i can hear the fan(s), but it is so quiet that the buzz from my desk lamp is probably 5 times louder.
    - my notebook is almost always pretty much silent like this. the last time i recall my fans ramped up was when i was updating my bios. easily the quietest notebook i've ever had.
