    Question GL502 electric buzzing noise - anyone else?

    I hate to post a rant thread as one of my first posts so lets start with positive things

    After owning middle tier Asus Notebook and the marvellous 2012 Zenbook ux52vz I purchased my first true gaming laptop going with Asus once again.
    Recently got my GL502VMK laptop with 8 GB RAM, 250 GB m.2 SSD and no OS installed. So far pretty happy with the machine and performance BUT

    after installing Windows 10, newest drivers from Asus site and Windows updates I noticed 3 things:

    - ROG Gaming center has unlabeled icons and is useless in terms of functionality. It only shows frequencies and temps. Thats it, no options to change fan profiles, CPU or GPU frequencies what so ever. It can only disable windows key etc for certain applications and open a shortcut.

    - No audio controls: WaveMaxx setup (from included driver disc) says it isn't compatible, the Realtek icon that should open Audio Wizard does nothing and this programs aren't available for download in the internet. Tried both included driver and latest audio drivers from Asus support site.

    - very noticable buzzing sound when in idle. I blamed the Micron SSD / controller first, after swapping it with another SSD however and trying fresh Win10 install it immediately came again. Turns out it's coming from CPU power delivery / VRMs which is most likely a mainboard issue (poor isolation)?

    After further examination and experimenting with different power profiles in Windows I have found very interesting things:

    - energy saving mode: almost no buzzing, much better; but reduced performance (you don't say?)
    - balanced mode: noticable electric buzzing
    - high performance: very disturbing high-pitch buzzing

    Modifying these profiles to "max CPU load": 99 % instead 100 % reduced the buzzing noise. Further reducing the max CPU load eliminated the buzzing but of course it isn't a viable solution. I have trained ears but even my mother could hear this abnormal noise very well. Have read about similar issues withsome Asus desktop Formula boards, but not in their laptop boards.

    Am I the only one with this problem? Going to RMA it ASAP and wait for replacement. Will report back after testing the replacement. I REALLY like the features of this laptop but this issues I can't ignore.

    FWIW, I don't own one but I can't recall anyone complaining about such an issue either. I would definitely RMA it as that could be a sign of other problems beyond annoyance.

    The Gaming Center Icons (I believe you are referring to the sections beside XSplit Gamecaster and Geforce Experience) will be populated by installing GameFirst IV, Icesound and I think ASUS Splendid Video Enhancement. You may not have Icesound but instead Sonic Studio and Sonic Radar I suspect that there is probably another app on the install disc you got for Fan Boost.
    Here is what you should have
    Wish I had a solution for the buzzing but for sure I would RMA it as it is likely a bad component causing it.

    I noticed Asus support page does not have links to download Fan Boost, Sonic Radar, and Sonic Studio so hopefully they are on the disc you got.

    I have a GL502VS I can hear a little if the room is quiet
    I thought it was the noise of the HDD, but I replace for an SSD and the noise remains.
    Probably a coil noise, but it is not loud like seems to be yours.
