    Ever since i updated to Snow Leopard it seems as if my fan on my white 13.3 macbook is always moving or on. I don't know if there is anything i should do about this. I do have applecare if that helps. Let me know if you have had any problems or if this is normal!

    How fast is the fan usually going? Download iStat Pro to find out. Mine is usually 1999rpm.

    Mine is at 1999 too, unless I'm using handbrake or something CPU intensive.

    Your fans are most likely OK. They are merely reacting to increased CPU temperatures that many of us are experiencing since upgrading to SL.

    Could you post a picture of the temperatures of your mac?

    The fans are messed in Snow Leopard.

    My fans would never EVER go on when I'm on YouTube, but once I upgraded they went on all the time. I did some experimenting, and it was Safari that caused them to go nuts so I went back to using good ol' Firefox and now my fans don't go on even on HD video! :eek:

    My fans are fine under snow leopard... always staying low, even relatively low when transcoding video.

    It isn't the fans. You guys are just seeing the side effect of a CPU that is running hotter. The fans are just doing what they're supposed to do.

    yeah i realize that, but why would be on because its not like im putting extraneous stress on my mac. the most i have open is itunes,mail and safari, and most of the time its just itunes and safari. i dont think native apps like that would make such a effect on my macbook?

    That's the $64,000 question, ain't it?

    I have no proof but personally I think Flash has something to do with it. Also, I think the coders did something to make SL interact differently with our GPU's. Who knows?

    I don't see any kind of fix though. Folks will just get used to it and this issue will fade away. Or maybe they'll sneak something into 10.6.2 but I wouldn't bet on it.

    Yeah. Because my macbook runs cool and quiet with snow leopard. Fans only go above 2000rpm when transcoding video etc... Fans are normal during youtube also.
