Hey, so I’ve been having this really weird issue with my Acer Nitro ANV15-51. The GPU fan randomly starts running at full speed even when the laptop is basically idle. Like, I’ll just be sitting there with nothing open except NitroSense, and suddenly the GPU fan kicks in like a jet engine, then slows down, then speeds up again, then quiets down and it just keeps doing that on and off for like an hour. What’s strange is that the temperatures are totally normal when this happens, and the GPU itself isn’t even active or being used.

There’s nothing heavy running in the background either. It’s super distracting and doesn’t make sense considering there’s no reason for the GPU fan to be acting like that. I bought this laptop around 10months ago and I barely use it just once or twice a week for a few hours each time, mainly for college projects using stuff like Django and other Python tools. I only gamed on it once, like seven months ago, and there aren’t even any games installed anymore. All I’ve got on here is Microsoft Edge and some development-related packages. I’m just trying to figure out what’s causing this because the fan behavior doesn’t match what the laptop is actually doing. If anyone’s experienced something similar or knows what might be going on, I’d really appreciate the help.

    You can try updating the BIOS to the latest version. I'm on version 1.26 and don't see any issue regarding the high GPU fan speed.

    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    Welcome @RexMods and @Sasmit_Singh1!

    Windows 11 is an “expert” in causing issues with the CPU cores constantly stuck at maximum clock, high temperatures and FANs operating at maximum speed.

    Below are some possible culprits:

    • Cortana (deprecated) or Copilot;
    • Device driver issue;
    • MS Edge stay running in background;
    • MS Visual C++ Redistributable library outdated;
    • Photos Legacy App;
    • Resume App;
    • Search Indexing (SearchHost.exe);
    • Windows Defender (WdFilter.sys);
    • Windows Memory Compression (MMAgent);
    • Windows Web Experience Pack (Widgets).

    From your screenshot, it's possible that NVIDIA Whisper Mode is causing a conflict with FAN control in NitroSense software. You can also test this by disabling this feature in the NVIDIA APP or GeForce Experience settings.
