    Dear friends,
    i have a problem with my macbook pro early 2007.
    It have 2gb ram, 320gb hd, and i've successful installed Mac Lion.
    It work good for me, but it have only one problem: the fans is often very loud.
    With iStat Menus i see that the speed is 5000rpm or sometimes 6000rpm.
    I dont have a lot of programs active. For example now I have only safari with this page and mail.

    Can you help me to solve this problem?

    If it's necessary i can downgrade to snow leopard, but lion is good and complete.

    Many thanks,
    I'm sorry for my english. I'm from Venice, Italy.

    Try resetting the SMC settings by following this Apple Support article.

    Neither Lion nor Snow Leopard effect the speed of the fan directly. They fans are controlled by the SMC. It is possible that Lion is taxing the system more than Snow Leopard.

    Given the age of that MacBook Pro I would suggest that you need new thermal paste, and potentially new fans.

    many thanks for the answers!
    I have already tried to reset the smc following the apple article, without benefit.
    ezramoore, your tips is interesting. I can try to change the termal paste.
    In your opinion, where I can find a good fans?

    Open Activity Monitor in the Utilities folder, set it to show all processes at the top of the window, and then click on the CPU% column to sort and see what process is causing the computer to work the hardest. Safari can cause the CPU to work at maximum load, particularly if flash is loaded and that will make the fans race.

    I recommend getting fans manufactured for Apple.

    iFixit has them here:"-Model-A1211#0-Fans

    however I would not buy there. They are charging way too much for them.

    If you want them PM me, as I can get them a lot cheaper.
