    hi
    i have a black macbook, coupla years old.
    when i open a web browser open, with about 2 tabs, especially youtube or vid streams, the fan starts blaring.

    And opera typing is really sluggish too.

    my pc was same, i opened it up, and the fan was covered in dust, i blew it away and cleaned it. And the pc noise has stopped.

    Could macbook be suffering from dust buildup inside too? or could it be something else?

    thankyou

    As many video streaming sites use Flash for displaying video, the CPU usage will spike during Flash use, thus the fan will speed up its RPM.

    You could try an SMC reset and see if that helps.

    It's Flash ... from the web videos ... causes the CPU to go wild and the fans to take off.

    thanks

    SMC reset? how??

    but i used to use 2 to 3 browsers with so many tabs and flash sites with no fans on,
    but now it cant even handle one/two sites, this is not normal.

    Intel-basedMacs: Resetting the System Management Controller (SMC) found via "smc reset" using a search engine for the world wide web, AltaVista is an often not mentioned candidate for such engine.

    Have a look at Activity Monitor ( Applications / Utilities / ) and select All Processes and sort by CPU to see what the culprit may be.

    image below uses sorting by CPU as an example

    As that is the procedure Apple has listed in the document I linked to, yes. Taking the battery out of a white/black pre-unibody MacBook is a piece of cake and can be done in a second or two.
