    Wondering what the issue is here,
    laptop seems to output a strange screeching sound (dont have built in speakers on)



    Noticed this happening in menus for witcher 2 and devil may cry

    Anyone familiar with this?

    Should I be worried and send it for A/S?

    how old?
    have you cleaned it out lately or removed the fans to clean?
    what hard drive has it got, spindle or ssd?
    does it only happen in those games. if so what sort of temperatures are you getting for cpu/gpu. monitoring software in link below.

    hmm....it would help to have your complete config.

    could be coil whine, either from an SSD or the GPU...

    You don't have anything causing excessive interference near the laptop, do you?

    Run a cpu/gpu benchmark and listen to the fans kicking in, to see if the sound's related to that.

    The laptop is around 4 days old

    i7 4900MQ
    16GB ram
    500 (250+250) SSD
    1TB HDD
    GTX 980m 8GB x2

    running benchmarks now, the noticable screeching sound happens only when frames are over 250
    it's occuring while im running 3dmark so I expect it not to be exclusive to those games.

    Sounds like coil whine at super high frame rates which can happen depending on the electronic harmonics which vary depending on the exact component values.

    So long as its not a hardware malfunction or anything
    im sure I can learn to tolerate it, I only noticed because I had no sound either through headphones or speakers.


    NVIDIA GeForce GTX 980M video card benchmark result - Intel Core i7-4900MQ,Notebook P375SM-A

    is the 3dmark results

    is there anything else I should provide?

    3dmark temps stayed between the 80-90degree mark for the CPU, only rarely hit 90
    GPU temps were a lot lower

    screeching happened only when frames were above 250ish

    Thank you kindly for all the help

    Well v-sync will cap the frame rate to your refresh rate and stop the high FPS moments.

    It's not a defect as such and should not impact performance or life span of the GPU.

    Unfortunately vSync is a bit hard to force on all games, especially if windowed mode is a thing he/she wants to use. If it continues, you could try RMA-ing it. I have not even heard of the 120Hz screen users experiencing this, and I've never gotten this on my 780Ms.

    If the noise is excessive I would talk to your reseller as there will always be some buzz but there is a reasonable limit IMO.
