    Whenever i open an application both of the fans go to 6000+ rpm in a couple minutes give or take.
    Strangely web browsing doesn't cause this speed but if a youtube video is played it gets up there fast.
    Applications such as quicktime and logic gets up there no matter what is played.

    I have fan control and smcfancontrol, 40GB free, software updated, tried the reset thing (turn off, hold power button, boot), cleared printing operations.
    The only thing smcfancontrol does for me is it slows down the fans quicker whenever i close all my applications.

    What did I miss? well apparently, ive done all that for nothing.

    Thanks, any help would be greatly appreciated.

    What model Mac do you have?
    Youtube/flash is notorious for making the CPUs work hard and the fans go very fast, especially in the older laptops.

    I guess Logic could do the same.

    You might have a runaway process using lots of CPU power. Look in Activity Monitor, but set it to All Processes and then sort by CPU.

    Download iStat Nano and look at your CPU temps on it
    Does the fan speed correlate with CPU usage or CPU temperature?

    If so then everything is normal, just a bit annoying.

    Downloading Flash 10 can help, it uses less CPU for Youtube.
