    CPU Fan makes rattling noise in iMac G5

    In my brand new iMac G5, the CPU fan makes rattling sound even when the temperature goes high. It has been updated with Mountain Lion 10.8.1. I am confused why the fan is making this weird noise. Please suggest a solution.

    hii friend,

    1)the rattling sound is heared when the system is under haevy usage
    2)so while doing any work stop all the background running apps in order to decrease the system performance
    3)use cooling pads to solve your problem
    4)some times it may be due to problem in the fan .so change the fan to solve your problem

    thanks for posting

    The problem is occurring because:-
    -There might be a lot for dust accumulated in the fan region.
    -Multiple heavy apps might be running simultaneously.
    -The system is getting heated up and the ventilation is not adequately working or blocked.
    -There might be problem with the fan.

    The solution to your problem is:-
    -Open the cabinet of your CPU.
    -Clean the dust accumulated.
    -Make sure you are not running multiple heavy apps simultaneously.
    -Use cooling pads for your CPU.
    -You may install another fan.
    -DO not block the ventilation.
    -If still problem persists,replace the CPU fan.

    Your problem will be solved.

    4.If still the problem doesn't get solved replace it with a new problem.

    Hi.............,

    This is a technical problem.
    Firstly you should take your mac to service center.
    If not possible then take to the software center.

    Now ask for the servicing of the mac.
    They will take few hours to service it.
    After the service your mac will run fine.
    So it is better to service the mac.

    If you manually operate the mac there may be some injuries to both.
    Rather you can check the carbon status of the RAM and fan issue.

    Thanks
