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.
