    My HD 3870 just arrived and the fan speed is unbearable in OSX (haven't tried Windows but what's the point).

    I did forget to install the Mac software before installing the card like the instructions said but I didn't read that :eek: and common sense says software goes after hardware installation.

    Anyways, how can I fix this? Could the card be defective?

    done so). Then, if the problem persists, you might wish
