    I can't be the only one.

    My HP NC4400 laptop runs very cool; could probably run without a fan at all.

    I'm wondering is there any way to remove the assembly language
    BIOS routine for fan operation and disable the fan/run fanless?

    There's gotta be a way!

    Thanks.

    trip points..?

    dsdt?

    how, exactly can I do this?

    can I theoretically, set the 'trip points' so that the fan NEVER goes on?

    thanks a lot

    extract dsdt.aml then use iasl to make it a text readable .dsl .. edit it then recompile as .aml then insert into bios file with the mod tool.
    seen it done.. but i havent done it.
    (learned this from insanelymac forum and also someone with an hp nc6400 ? with ati video would cause overheat.)
