    Definitely not 7 screws, could be 6 but I am guessing it was 2 like on the picture, the rest was removed before and the 3rd from the right is a push-button :P

    I still need to do the reassembly, I will try to pay attention to these details and take some pictures to improve the guide.

    • Caution: When removing the fan, be careful to not tear the attached ribbon cable.

    • Unscrew all five screws from the internal fan.

    Take heed!

    First remove the mainboard screws and take note of what goes where.

    The heatsinks will come off when you remove the screws securing the fan and you will have to clean them and reapply thermal compound.

    Far from done here..

    TAKE NOTE OF WHAT YOU REMOVE NEXT, you will need the notes when you put it together again.
