    Hello everybody,

    After I came home from school and turned on my laptop one of the fans seems to be making this rattling sound (https://vocaroo.com/i/s125iLYJsAvv sorry about the bad quality of the sound I'm only talking about the foreground rattle and not the background hiss) when the laptop is idle or doing things like browsing or watching videos.

    When the temps go up and the rpm increases the rattle goes away completely. So the laptop ends up being quieter at 49C than when it's idle at 39C.

    What do you think I should do?

    Some advice would be appreciated.
