    Subject[PATCH v2 3/3] platform/x86: asus_wmi: Set default fan boost mode to normal
    Date
    Set default fan boost mode to normal for multiple reasons:

    1) existing code assumes that laptop started in normal mode and that is
    not always correct.
    2) FX705DY/FX505DY starts in silent mode and under heavy CPU load it
    overheats and drops CPU frequency to 399MHz [1]. Setting fan mode to
    normal avoids overheating.
