    Hi all.
    I have strange beep/chrr noise from up left corner of my macbook pro i7.
    This is happening only when I am watching youtube/vimeo or something video over flash player (10.1). I tried HW acceleration on/off and still this problem.
    Later I noticed this problem is only with Safari, when I use Firefox or Chrome problem does not exist. Reinstalled flash, cleared all caches, still there.
    By watching .flv in VLC, QuickTime or Movist also nothing... My safari is 5.01 version.

    Any suggestions? Thanks for help

    Use iStat Pro to monitor your temperature and fans.

    They normally spin at 2000RPM, which is the idle speed, but as Flash is CPU intensive, the CPU gets hotter and the fans start to spin faster, which becomes more audible.

    Could be the PSU, it might draw more power during those CPU intensive tasks. Run Cinebench or any other CPU intensive benchmark or test (Handbrake, ...) and see, if the sound reappears.

    New Update... now I noticed this beep/chrr sound is only when video is on screen, so when I scrool down and video is on top and I can't see it, this problem with beeping is not there... any suggestions?
